Brickner, Muskegon Heights, Mich., as signor to Brîckner-Kropf Machine Company, ' Muskegon Heights, Mich., a corporation of Michigan Application October` 19, 1936', Serial No. 106,400 4 Claims. (Cl. 29-76) lI’his invention relates to a filing machine which is particularly useful for the purpose of> filing and lapping die punches though of course it may be used for filing other work. However, 5 in the process of making punches for dies', after the same have been roughed out to approximate size it has been considered heretofore necessary to do the final finishing and honing operations upon the punch by hand, this adding to the cost of the punches'and in fact being a large item in the cost. In accordance with my inven tion a very practical and useful filing machine is provided, particularly adapted for the purpose stated and' in which the ñle is held at its upper 15 end above the work to be ñled, the lower por tion of the iile is free of any connection and mayl operate upon a die punch directly downward to a shoulder at the lower end of the die punch,V which is substantially if not entirely a universal. 2U element or part of die punches. The machine is further equipped with means for angular adjust ment whereby the ñle or the work may be ad justed at an angleY to the perpendicular so that the die punch operated upon by the ñle may 25 be filed at an angle either from its. upper end> downwardly and outwardly or from. itsV upper end downwardly and inwardly. There. is also pro vided a means for adjusting the file holding part> of the machine in a vertical> direction so that 30 files of different lengths may be used in the Like reference characters refer to like parts in thediiïerent figures of the drawings. The machine includes a supporting pedestal l having a head 2 at its upper end above which is a generally horizontal table 3 which has down wardly extending ears 4 between two oi its op posite edges, a pivot rod 5 passing through the ears and through suitable lugs on the head2 of the pedestal whereby the table may` have a limited angular adjustment about the axis cf 10i the rod 5. An ear or lug 6 extends downwardly near one of the sides of the table 3 and is ver tically slotted, through which passes a set screw 'I threading into the head'V 2 of the pedestal to> secure the table 3 in any position to which it may be adjusted. It is evident that adjdstmentv may be made within the limits prescribed for the length of the slot in the ear or lug 6. - ‘ At the rear side of the head 2> an arm 8, inte- grally formed therewith, extends rearwardly' and 20 upwardly and terminates in a; split sleeve 9 hav ing upper and lower ears 9a; at its rear side above and below the parting in the sleeve and which may be drawn together by a screw l0 toY clamp the sleeve upon a cylindrical boss H which ex tends laterally at the lower end of a substanf tially vertical arm I2 of a support for the ñling head. At the upper end of the arm> I2 'a hori-y zontal arm i3 extends forwardly so as to lie over the table 3, terminating in a head I4. . The head I4 at its front side is machined to provide a recess for the reception of two» spaced very readily quickly and accurately adjusted to v apart vertical gibs I5> and i5 which areV fastened to the head I4' at its front'sid'e by means of any desired length. suitable machine screws.

Fig. 5 is a fragmentary' view illustrating a feature of the construction for the angularly adjustable mounting of the support for the filing 55 head. the gibs thereby making it desirable that the wear be thus compensated. The slide i8 hasl 45 a plate I9 at its front side permanently secured so asV tov be in effect integral therewith. The slide unit at the lower end has forwardly ex tending jaws 20 which may be clamped by means of, a clamping screw '2l against' the shank of al ñle 22, the ñle extending downwardly toward the table as shown. ' ' ' ' " ' _i An electric motor 23 is supported onV a‘suit able bracket or shelf at the; rear side ofthe pedestal I and has a‘driveA pulleyllllon its shaft; 50. 2 ` ` 2,114,994 which, through an endless belt 25, drives a driven pulley 26 secured to a shaft 21 mounted for ro tation in suitable anti-friction bearings in and extending through the cylindrical member I I. At its opposite end the shaft 21 is equipped with a cylindrical head 28 which has a T-slot 29 in its outer face passing diametrically across the head. f j ' On a suitable pivot 30, at the upper end of perpendicular may be attained. It is further evi dent that the holder for the upper end of the ñle shown in Fig. 4 is one which can take the shank of the ñle whether of the cross section shown in Fig. 4 or any other conventional cross sectional shape used for the Shanks of ñles. The machine described has proved very prac tical and' useful', eliminating as it doesv a very great deal of the-hand filing which has hereto 10 the arm I2, a bell crank lever is mounted for fore been considered necessary in machining die 10 rocking movements, having a downwardly ex- f"punches to substantially accurate finished sizes. The invention is defined in the appended claims tending arm 3| and a forwardly extending arm. and is to be considered comprehensive of all 32 as best shown in Fig. 3. The arm 3| at its lower end is equipped with an open framel 33. forms of structure -coming within their scope. I claim: 15 A bolt 34, having a head 35 located in the T-slot 1. In a machine of the class described, a sup 29 (Fig. 2), passes through a block 36 which is located in the frame 33 and slidable between its vertical sides. A clamping' nut 31, to clamp against the frame 33, is threaded onto the outer 20 end of the bolt 34. By means of this construc tion there is an adjustment of the bell crank lever relative to the rotative axis of the head 24 where by the arc of movement of the bell crank lever may be varied, being increased the farther the 25 bolt 34 is moved away from the axis of rotation of the shaft 21 and the head 28 thereon. The forwardly extending arm 32 of the bell crank lever is forked atits front end and carries a pin 39 which extends through a horizontal 30 slot in the rear side of a block or member 38 to ñxed onto the end of the shaft, an eccentric pin on the head, an L-shaped crank medially pivoted on the said support, one end of the crank being slotted to receive the said eccentric pin to cause oscillation of the said L-shaped crank, the other arm of the L-shaped crank having an 'ex tension thereon and means cooperatively asso ciated with the extension and the said plate to cause reciprocation of the said plate. 2. A filing machine of the class described hav-` 40. ing a pedestal, a horizontal table, means for A, screw 4I passes through a clamping block member ’42 being of less length than the slot 40, ' so that by loosening the screw 4I theslide with f the attached ñle may be verticaly adjusted to any 30 mountingl the table for tiltingmo-vement relative 35 ly to the pedestal, a horizontal supporting sleeve, means for mounting the` supporting sleeve- at right angles to the axis of the means about which ciprocatory movements, the length of the ystroke being governed by the position in which the the table is tiltable, an L-shaped support includ ing a boss, near one end of said support, oscil latable in said sleeve and having its otherend extending above the table, a sliding mechanismn frame 33 is held relative to- the head 28, the position of the file relative to the table 3 being slidably mounted upon said arm for movement toward and away from the said table, means for f desired position. It is evident that , with the motor 23 operating the file is given vertical re governed by the adjustable connection ofthe adjustablyV clamping the said boss in said sup slide I8 to the member 38, and the angular posi Vtion of the ñle relative to the perpendicular being governed by the adjustment of the member I2 and the cylindrical boss II at its lower end in the clamping sleeve 9.

In case the punch is not thus enlarged at its lower end so as to make the shoulder 45, there will be the same condition present in effect in 65 that there will be a horizontal shoulder between the lower end of the punch and the block 44 on which it rests. The file, being held at its upper end and depending below the head supporting’it, may be used to file the punch 43 to the shoulder 70 at 45.
