Greenough, Beverly, Mass, assignor to United Shoe Machinery Corporation, Paterson, N. 3., a corporation of New Jersey Application December 22, 1936, Serial No. 117,163 9 Claims. (Cl. 12-‘-i) This invention relates to ?nishing machines a rotating tool it) which applies a ?nishing and is illustrated herein as embodied in a ‘machine adapted for ?nishing the heels of shoes. The ?nishing of shoe heels by the use of the 5 usual type of ?nishing machine requires an oper ator to present the work successively to a number of different ?nishing tools arranged at spaced points along a ‘rotating shaft. The losses of time and energy of the operator occasioned by thus 10 moving the work from place to place are ma~~ terial and ‘are factors which it is an object of the present invention to avoid. I To this end, the presentation of the work to the" ?nishing tools of the ‘illustrated machine is 15 effected at one operating point past which the tools are moved in succession as a result of being mounted, in accordance with ‘an important fea ture of the invention, on a constantly moving carrier or turret, the spacing of the tools on the 20 turret being determined with reference to the dif ferent amounts of time required to carry out the granted December 20, i898, upon the application 5 of Z. Beaudry, and is ?'Xed on the left-hand end of the shaft i2 (Fig. 1) which is supported ad jacent to the tool by an arm M, the latter being fixed to a bracket l6 which is fastened to the machine column iii. The shaft I2 is also ro- 10 tatably mounted at its right~hand end in a hear ing member 2E1 ?xed to the top of the column It. The shaft 12 is driven by a belt 22 which runs over a pulley 24 ?xed to the shaft l2, the belt being driven from any suitable source of power, v15 as an electric motor 26. The ?nishing medium is supplied to the tool it by a disk 28 rotatably mounted in a medium holder 30, the construction and mounting of which is the same as that of the machine illus~ >20 trated in Letters Patent of the United States No. various operations so that there is substantially no 1,636,333, granted July 19, 1927, upon the applica; lost time between the completion of one opera? tion and the arrival at the operating point of the tion of J. F. Standish. As will be fully understood from the above-mentioned Standish patent, ad, justment of the disk 28 transversely of the axis 25 of the tool It is effected by turning a crank 32 25 succeeding ?nishing tool. > As herein illustrated, the ?nishing tools have a uniform orbital movement with respect to a tool for applying ?nishing medium to the work, the applying tool being located conveniently with re— 30 spect to the operating point of the ?nishing tools whereby a minimum of movement of the operator is required in presenting work to the ?nishing tools after the work has received an application of ?nishing mediumv 35 These and other features of the invention‘. will be apparent from the following description when read in connection with the accompanying draw lugs and will be pointed out in the claims. In the drawings, 40 medium, such as wax with or without ink, to the heel. The tool If! is of the “type disclosed in Letters Patent of the United States No. 616,432, ' Fig. 1 is a front elevation of an illustrative ma chine embodying the invention; Fig. 2 is a side elevation illustrating the ?nish ing tools and the turret upon which they are mounted as viewed from the left-hand side of the 45 machine shown in Fig. 1; and ~ which operates a slide 34 on which the holder 39 is mounted. The slide 34 is mounted in a dove tail slideway formed in a block 35 which may be clamped to the upper end of the bracket iii in 30 any desired position of adjustment axially of the shaft 52 by means of bolts 33 which pass through elongated slots E6 in the bracket 55. The disk 28 may be driven from the shaft M by any suit able means, such as beveled gear connections, as 35 illustrated in the Standish patent, or by means of a belt 42,'as in the present machine, which runs over a‘ pulley "i4 ?xed to the shaft l2 and a pulley 58 associated with the disk 28. The shoe heel, having had wax applied thereto 40 by the tool it, is next moved to an operating point in front of the machine to which ?nishing tools comprising a padding wheel (38, a rand burnishing and beading wheel 50 and two rotary brushes 52, 5a are brought in succession as a result of their 45 being bodily rotated, as will be described later, in an orbital movement with respect to the tool hand side of the machine shownin Fig. 1. it and shaft I2. Each of the above-mentioned Although the present invention may have ap ?nishing tools is journaled in a head 56 and each plication in a machine adapted for performing head is adjustably' ?xed in a turret comprising 50 50 any ?nishing operation on a shoe, it is disclosed herein with reference to the ?nishing of heels a disk 58 having a tubular hub 68 journaled in the bearing member 26 and adapted to receive of shoes. In the finishing of a shoe heel by the the shaft M. A guard member EiZ'surrounds the use of the illustrated machine the heel, which will have been prepared for the ?nishing operation as I heads 56 and has a series of elongated slots 64 55 by scouring and bui?ng, will ?rst be presented to adapted to receive screws 66 threaded into the 155 Fig. 3 is an elevation as viewed from the right 2 2,110,933 heads 56. Alined radially with respect to the slots 54 are other slots 68 formed in the disk 58 and adapted to receive clamp bolts 10 for secur ing the heads 55 to the disk 58. The disk 58 is rotated at a relatively slow uniform velocity, so that the operator has enough time to present the work to the tools, by a gear train comprising a worm gear 12 ?xed to the hub 65, the gear being driven by a worm 74 carried by a shaft 15 jour 10 naled in an extension of the bearing member 28 and having mounted on its end remote from the worm 74 a worm gear 18. The gear "I8 is driven by another worm 86 mounted on a shaft 82 jour naled in the bearing member 20 and carrying a 15 pulley 84 at its outermost end in the plane of the ~ pulley 24 to facilitate its being driven by the belt 22. Thus, when the motor 26 is operated, the wax-applying tool shaft l2 will be rotated and the ?nishing tools 48, 55, 52, and 54 will be bodily ro tated with respect to the tool iii at such a speed that each tool will remain in the vicinity of the operating point above referred to long enough to enable an operator to ?nish that operation for which each operating tool is intended to be used. 25 The angular spacing between the ?nishing tool heads 55, as illustrated herein, is irregular and is to be determined with reference to the differ ent amounts of time required for each ?nishing operation, this angular adjustment of the ?nish 30 ing tools with respect to each other being per mitted by the slots 64 and 68 which allow the heads 55 to be adjustably clamped in the turret in any desired relation to each other. t will be noted with reference to Fig. 2 that the greatest 35 spacing between the tool heads 56 exists between that carrying the brush 54, which is the last ?n ishing tool to be brought to the operating point during one cycle of the operation of the machine, and the padding tool 48 which is the ?rst tool to which work is presented after it has received an application of wax from the applying tool Hi. This wide spacing of the padding wheel 48 and the brush 54 gives time for the operator not only applied thereto, the shoe heel will be ?nished by being operated upon successively by the padding wheel 48, the rand burnishing and beading tool 55 and the brushes 52 and 54. Owing to the above-described slot arrangement by "which the heads 56 may be angularly adjusted relatively to each other in the turret, the spacing between the ?nishing tools may be readily controlled with reference to the time required for each particu lar ?nishing operation so that there will be sub stantially no lost time between successive finish ing operations as explained above. It will thus be apparent that a minimum of effort is required of the operator in presenting the work to the applying and ?nishing tools and that by prop erly relating the speed of rotation of the turret and the spacing of the ?nishing tools an eilicient speed in carrying out the various ?nishing op erations is encouraged. Having described my invention, what I claim as ‘new and desire to secure by Letters Patent of the United States is: 1. In a shoe ?nishing machine, a rotating ?nishing medium applying tool, and a plurality of finishing tools mounted for movement bodily in - a path surrounding the axis of said applying tool at a constant velocity’ past an operating point at which a shoe is presented to said tools in succes sion, said ?nishing tools being irregularly spaced so as to permit the operator to interchange a l ?nished shoe for one to be operated upon and apply medium thereto during the period when the last ?nishing tool leaves and the ?rst tool reaches the said operating point. 2. In a shoe ?nishing machine, a plurality of ?nishing heads each comprising a tool, a carrier for said heads, means for moving said carrier con tinuously whereby said tools are successively moved through an operating position at which a shoe is presented to said tools, said heads being 40 mounted for adjustment on said carrier in the direction of itsmovement thereby to permit spac ing said heads relatively to each other in accord ance with the time required for each ?nishing to place a ?nished shoe aside but also to pick up one to be operated upon and to apply wax to operation. 3. In a shoe ?nishing machine, a plurality of the latter as the padding tool 48, owing to the movement of the turret, is moved to the oper . ?nishing heads comprising tools adapted to be used in succession in ?nishing a shoe, a carrier ating point. It will be understood that the angu lar spacing between the ?nishing tools 48, 50, on which said heads are mounted for adjustment 52, and 54 may be adjusted at the will of the relatively to each other, and means for moving operator to suit the requirements of various types said carrier at a uniform velocity whereby said of work so that there will be substantially no loss heads are successively moved through an operat of time between the different ?nishing operations. ing position at which a shoe is presented to said The ?nishing tools 48, 55, 52, and 54 are also tools, the space between that head used to com plete the ?nishing of one shoe and that used to : rotated about their own axes by connections com begin the ?nishing of the succeeding’ shoe being prising belts 85 which are driven by pulleys 88 which are ?xed to the shaft 12 between the arm greater than the space between successive heads used in ?nishing the same shoe thereby to com l4 and the disk 58. ' pensate for the time required in substituting for Although the operation of the illustrated ma a ?nished shoe one to be operated upon. 60 chine will be clearly understood from the fore 4. In a shoe-?nishing machine, a tool for ap going description, it will now be summarized. The holder 39 having been adjusted to bring the plying ?nishing medium to a shoe, a turret wax-applying disk 28 into the desired relation carrying a plurality of rotating tools to which a 7 to theapplying tool H1 and the motor 26 having shoe having had medium applied thereto is pre— been started, the operator presents the heel of a sented, and means for continuously rotating said shoe to be ?nished to the applying tool it which turret whereby said rotating tools are bodily applies and distributes the ?nishing medium or rotated with respect to said applying tool, the last and ?rst tools on said turret to which the wax evenly over the peripheral surface of the heel. Owing to the proximity of the applying tool iii to the operating point at which the work is presented to the ?nishing tools 48, 55, 52, and 54, the operator is able merely by swinging his body and without moving his feet to move the shoe from the applying tool id to the ?nishing tools. After having had ?nishing medium or wax shoe is presented being spaced from each other at a greater distance than that between other successive tools thereby to permit the inter change ci a ?nished shoe for one to be operated upon and the application of medium to the latter by the use of said applying tool. 5.
