A primary object of the present invention is the provision of a leather polishing apparatus 5 which is simple and inexpensive in construction, and which is efficient and speedy in operation. A further object of the invention is the provision of a leather polishing apparatus which com- jacent the longitudinal center of the frame, and a like support it interconnecting the opposite end supports l3 intermediate the sides of the frame. The frame also includes opposite end vertical supports l1 and a vertical support I!!! ‘ ‘Di between the opposite ends of the frame. The numeral l9 designates a polishing roll which, in accordance with the invention, is pref prises a polishing roll, a conveyor or feed roll, 10 and a kick~oif brush cooperating with the pol- erably constructed of woolen disks as indicated ‘in Fig. 1, each of the discs preferably being con- 10 ~ structed of small pieces of sample wool as is in- . ishing roll; and separate adjustable driving means for the polishing roll, the‘ feed roll, and the kick-off brush. A still further object of the invention is the 15 provision of a leather polishing apparatus comprising a power-driven polishing roll, an adjust~ able power-driven feed roll for presenting leather to the polishing roll, and a chute for returning the polished leather to the operator. 20 A still further object of the invention is the provision of a leather polishing apparatus com- (heated in Fig- 3, the discs being fastened to a Wood core as indicated at 20 in Fig. 3. The polish ing roll may, however, be constructed of wool cloth suitably secured to the shaft later referred 115 to. The roll I9 is supported by a shaft 2| which at one end thereof is journalled in a bearing 22 and which inwardly of the opposite end thereof is journalled in a bearing 23. Each of the bearings 120 22 and 23 is adjustably supported on the threaded prising cooperating polishing and feed rolls which studs 24 projecting downwardly from a bearing are of improved construction for assuring accurate feed of the leather as well as 'a uniform ?n- supporting bracket '25 which is suitably secured to the supports [5. The bearings 22 and 23 can ‘25 ish to the surface thereof. A still further object of the invention is the provision of a leather polishing apparatus embodying novel cooperating elements to secure uniformity of polish on the leather and adjustable means for varying the readily be adjusted upen proper turning of the 725 nuts 25 On the Studs 24 whereby the polishing r011 i9 can be Properly adjusted With ‘respect to the feed roll, later described, as may be occasioned as the surface thereof becomes worn. so degree of polish. The invention consists in the improvements The shaft 2i extends beyond the bearing 23 and ‘30 has Suitably Secured theTetO externally 0f the hereinafter describedand claimed. In the accompanying drawings, forming a part of this speci?cation: 35 Figure l is a front elevational view of a pre- frame a belt-wheel 21 which is operatively con nected by a pair of V-belts 28 with a smaller belt Wheel 29 which is carried by the outer end of the 40 Shaft 311 Of a motel‘ 35, supported on ‘a Suitable 3'5 ferred embodiment of the present invention; base 32. Figure 2 is a left-hand end elevation; and Figure 3 is a right-hand end elevation of the construction illustrated in Figure 1. The meter 35 is preferably of three (3) horse power and has sui‘?cient velocity to drive the roll it at a velocity of substantially 850 revolutions The same numerals of reference are used to designate like and corresponding parts in the various ?gures on the drawings. The frame by which the various operating and driving elements are supported may be con4-5 structed of relatively heavy wood pieces or it may be constructed of angle-iron. The frame as illustrated is constructed of the former and com- prises vertical corner posts IE, top, intermediate, and bottom horizontal end sup-ports H, i2 and 50 !3,respectively, at the opposite ends of the frame, and a horizontal support it connecting opposite corner posts at each side of the frame intermediate the top and bottom thereof. The frame further comprises a pair of horizontal supports it 55 interconnecting the opposite end supports II ad- DB1‘ minute- ‘ - ' 4O In Order to provide Sufficient driving tension in the belts 28 as well as to provide for easy re placement thereof the motor base 32 is preferably adjustably mounted in the frame which may-be of any suitable construction and which as illustrated 45 preferably comprises guide-ways 33 in one of the rear corner posts !4 and in the support I 8, in which guide-ways are slidably disposed guides 34 on the base 32, the base being secured in any adjusted position by means of nuts 35 engaging 50 Studs 36 projecting thl‘ellgh elongated slots 3? in the base 32. The roll I9 is adapted topolish the surface of the leather which is presented thereto upon a suitable table 38 having an opening v39 therein to 55 ' 2 2,109,687 permit the polished leather to follow the chute, later described, as well as to provide operating space for the propelling or feed roll 40. The feed roll is mounted vertically below the polishing roll I9 and is co-extensive in length therewith. The feed roll preferably comprises a cork-covered cylinder suitably secured to a shaft M which, at opposite ends thereof, is journalled in bearings 42, each of which is supported by a base 43 slidably disposed in a guide-way 44 in one of the supports I‘I. Secured to the right hand end of the shaft 4I exteriorly of the frame is a rela tively large sprocket-wheel 45 in driving engage ment with a roller-chain 45, which chain engages 15 a small idling sprocket 41 and is driven by a small sprocket 48 ?xed on the shaft 49 of a motor 50. The motor 50 need only be of about three quar ter horse power to drive the feed-roll, which has a velocity of only about ten, (10) revolutions per 20 minute. The feed-roll 49 is adapted to be raised and lowered in the operation of the machine, and this is effected by means of improved mechanism which not only raises and permits lowering of 25 the roll but provides for an adjustable uniform pressure on the leather being polished. The roll the roll I9 as well as to de?ect the same toward the return chute, later described, a kick-off brush ‘I3 is provided. The rotary brush ‘I3 is carried by a spindle or shaft ‘I4, which shaft is journalled at opposite ends thereof in bearings 15 ?xed to opposite end supports I2. Secured to the shaft ‘I4 inwardly of the adja cent end of the frame is a belt-wheel ‘I6 opera tively engaged by a pair of V-belts ‘II which en 10 gage and are driven by a smaller belt wheel ‘I8 ?xed to the shaft 2I inwardly of the main drive belt-wheel 2'! carried thereby. In order to provide sufficient driving tension in the belts ‘II the same are engaged by an idle roll 15 ‘I9 suitably journalled on a block 80 vertically movable in a guide-way 8I in a bracket 82, the block being retained in adjusted position by means of a bolt 83. In order to protect the operator against in 20 jury from ?ying particles from the roll I 9 as well as the roll itself, a sheet metal guard 84 is suit ably secured at the upper edge thereof as by hinging to one of the supports I5, as indicated at 85 in Fig. 1, and securing the lower edge there 25 of in slightly spaced relation to the table 38 by 45.‘ is manually raised by means of a foot-treadle brackets 86. EI comprising a longitudinally disposed slat 52 supported adjacent each end thereof by one end The invention comprises an improved means for returning the polished leather to the oper 30 of a bar 53 whose opposite or inner end is pivot ally connected at 54 to an ear 55 projecting down wardly from the support I6. Pivotally connected at 55 to the support I6 adjacent each end there of is a bell-crank lever 51, one arm of which is 35 pivotally connected at 58 to an adjustable link 59 and the other arm of which is pivotally con ~ ator and which, in a preferred form, comprises 30 a sheet metal chute 81 which is preferably se cured at the upper edge thereof to one of the supports I5, as indicated at 88, and which is suitably secured at the lower edge thereof to a longitudinally-disposed strip 89 adjacent the slat 35 to the respective bearings 42. 52 of the treadle 5|. The chute 81, as is clearly illustrated in Figs. 2 and 3, is concaved toward the operator and has su?icient inclination to permit the polished leather to fall by gravity to the feet of the oper 40 ator. The chute 8'! is co-extensive in width with This construction provides a simple and effi cient means for raising the feed roll 40 into en brush ‘I3, and is preferably provided with lateral nected at 6!! to one end of a link BI whose oppo site end is pivotally connected at 62 to the ad jacent bar 53 outwardly of the pivotal connection 54. The links 59 are pivotally connected at 63 gagement with the leather as it is pushed forward 45 on the table 38 for compressing same between the rolls I9 and 4E! and feeding same forward during the polishing action of the roll I9. A coil spring 54 is preferably connected with the treadle and the frame, as indicated in Fig. 3, 50 to normally hold the feed roll in inoperative posi tion. In order to provide a uniform pressure on the leather being polished an adjustable stud E5 is carried by the slat 52 adjacent each end thereof 55 and is adapted to _. engage a stop 66 when the feed roll is fully elevated, as is illustrated in Fig. 3. The studs 65 are provided with adjust ing and securing nuts 61 and 68. In order to effect further adjustment of the feed roll the ad 60 justable links 59 may be shortened or lengthened. These adjustments in the feed roll actuating means further provide for varying the pressure on the leather for effecting different degrees of polish as may be desired on different grades of 65 leather. When the feed roll is in lowered or inoperative position the chain 46 will be slack and in order to provide su?icient driving tension in the chain when the feed roll is in raised operative position the idling sprocket 41 is carried by a block 69 vertically movable in a guide ‘ID in a bracket ‘II disposed on the right-hand support I2, the block being retained in adjusted position by means of a bolt ‘I2. In order to prevent adherence of the leather to the length of the rolls I9 and 40 as well as the guide-?anges 9B. In the operation of the con struction disclosed the leather is placed upon the 45 table 38, whereupon the operator presses the treadle 5| down until the studs 65 engage the stops 66, and the feed roll 40 will, through the linkage above described, be brought into engage ment with the leather and will compress same 50 against the polishing roll I9 and feed the same uniformly toward the kick-off brush ‘I3. The kick-off brush will release the leather from the roll I9, whereupon it will fall onto the chute 81 55 and return to the operator. The cork-covered feed roll is not only yieldable but affords suf?cient frictional engagement with the leather to uniformly and consistently feed the same forward, and the woolen disc polishing-roll presents a highly effective ?nishing surface to 60 the leather being treated. As the feed roll rotates only about ten ( 10) revolutions per minute while the polishing roll rotates about eight hundred and ?fty (850) revolutions per minute or eighty-?ve (85) times as fast as the feed roll, the surface of 65 the leather will be subjected to an effective pol ishing action by the roll I9. From the foregoing description, it will be seen that the improved machine in accordance with the present invention is highly ef?cient in opera 70 tion as well as being capable of polishing leather rapidly, and that the machine embodies such ad justments as to assure such efficiency in operation even after long periods of use. While I have disclosed a single speci?c em 75 3 2,109,687 bodiment of my invention, nevertheless it is to be understood that the same is to be considered as illustrative and not restrictive, the scope of the invention being de?ned in the subjoined claims.
