IMPROVEMENT IN HEEL FILING AND BUFFING MACHINES.

Specication forming part of Letters 'Patent No. 175,882, dated April l1, 1876 i application filed July 24, 1875.

To all whom it may concern:4

Be it known thatwe, HEEMON O. TOWER and JOHN N. TOWER, both ofthe town of H udson, county ot' Middlesex, State of Massachusetts, have invented a Heel Filing and Buffin g Machine, of which the following is a specification Our invention has for ils object the combination, in a single machine, of a filer and a sandpapering or huiiing device, in such a manner and with such additional appliance that the combination furnishes a machine which .will smooth the bottoms of boots and shoes in a i rapid and thorough manner.

Figure 1 is a front elevation of our machine.

Fig. 2 is an end elevation of the same. Fig. 3 is a plan of the saine. Fig. 4 is a view of the device for holding the hoot or shoe. Fig.

5 is an enlarged plan of the device for holding the boot or shoe.

Let A represent the frame of the machine, to which the working parts are attached. B is the main or driving shaft. C is a belt, eX- tending from the pulley C, Fig. 1, to the shaft D of the sand-paper roll D. This sand-paper roll is inclosed in casing E', Figs. l, 2, and 3. E is an ordinary blower, driven by the belt P', which serves to draw oli" the dust which is made by the sandpaper on D. This blower also acts to make a draft to draw olf the lings and dust that is made by the ille-Wheel F3 ,Figs 2 and 3, the current passing through the pipe F, Figs. 1, 2, and 3. F3 is a file-wheel, inclosed in the casing F2, and driven by the shaft F4, pulley H, and belt K, Fig. 1. object of the file-wheel F3 is to take oft' the The V ends of the nails, and to even the surface of the leather-that is, bring the surface Of the heel to an even surfnce--sothat the sand-paper on 1) has only to put on afinal finish, thus saving the sand-paper from most of the work. The file-wheel F3, working roughly, rapidly reduces the surface of the heel, and thus saves time. The jack for holding the boot or shoe is shown at L, Fig. 4. This jack is provided with an adjustable end piece L3, Figs. 3, 4, and 5, and is attached to a movable arm, M, Figs. 2, 3, 4, and 5. This movable arm M is hung on an adjustable pivot at M1, Fig. 5, and is held back by the spring N, Fig. 5. It can be thrown forward by the foot-lever N4, Fig. 2, which acts through the strap N3, Fig. 2, N1, Fig. 5. Thejack L swings on the arm M, and is held by the spring-clutch L3 L4, the pin L4 playing in an annular groove (not shown) on M. The opening in L, Fig. 4, is provided with a lixed key, M2,whicl1 tits in a corresponding keyway, M3, made on M, Fig. 3, so that the jack L cannot turn below the position shown in Fig. l, though it is free to be turned up for receiving the boot or shoe.

We claim- The combination of the jack L, provided with the spring-clutch L3 L4, the adjustable arm M with the tile-wheel F3, all substantially as shown and described.
