HEEL-NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 305,723, dated September 23, 1884.

(No model.)

To aZZ whom, it may concern:

Be it known that I, MERRILL A. TYLER, of North Easton, in the State of Massachusetts, have invented certain Improvements in- Heel- Nailing Machines, of which the following is a specification.

This invention has for its object to provide certain improvements in heel nailing machines, whereby, first, a heel may be pricked or perforated, nailed, and provided with a blind-lift at one jacking; and, secondly, different sizes of boots or shoes can be treated in the same machine.

The invention consistsin the improvements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a vertical central section of myimproved machine on line or m, Fig. 2. Fig. 2.1epresents a front elevation of said machine. Figs. 3, 4., 5, 6, 7, S, 8, 9, 10, 11, 12,13, and 14 represent detail views.

The same letters of reference indicate the same parts in all the figures.

In the drawings, A represents the general supporting-frame of the machine. B represents a horizontal bed or table, of circular shape, (see Fig. 10,) having any desired number of gangs of nail-holders 0, each holder being an orifice extending through the bed and of suitable size to receive a nail, and each gang being a group of such orifices arranged like nails in a heel. Said gangs are of different sizes, each being adapted to a different sized heel. In the present'instance the bed has three gangs, and is adapted to rotate on a fixed standard, D, Figs. 1, 10, 11, and 12, attached to the frame A. Each gang is thus adapted to be brought to the front of the machinethat is, to a position over the jack and under the awls and drivers, hereinafter described. The bed B is locked in as many positions as there are gangs of nail-holders by a Lil vertical bolt, E, adapted to slide in the frame A, and engaging with perforations G'in the bed. The bed Bis adapted to slide vertically on the standard D, and is supported by a spring, H, which enables the bed to have a yielding movement under downward pressure, thevcrtical arrangement of bolt E enabling the bed to be depressed to a limited extent without being disengaged from. said bolt.

I represents a plunger adapted to slide between vertical guides J J (see Fig. 2) on the frame A, and is reciprocated vertically by a driving-shaft, K, having a cam, L, connected by a connecting-rod, M, with the upper end of said plunger. On the horizontal bottom surface of the plunger I are formed two parallel shouldered guides, N N, adapted to receive between them and thus support a plate, 0, having a gang of awls, 1?, or a plate, O, having a gang of drivers, It. Said plates 0 O are placed side by side, and are adapted to slide in corresponding shouldered guides, A A A A affixed to the frame A at opposite sides of the plunger I, and coinciding with the guides N N of the latter whenthe plunger is raised, as shown in Figs. 1, 2, S, and 9, the guides A, N, and A being then continuous, so that said plates, or either of them, can slide from the guides A to the guides N, or from the guides N to the guides A or the reverse. The plates 0 O are disconnected from each other, and each, when it is supported by the guides N N, virtually becomes a part of the plunger, and rises and falls therewith; hence,

when it is desired to prick or perforate a heel, the plate 0, with its awls, is engaged with the guides N N of the plunger, the plate 0, with the drivers, remaining at rest in the guides A as shown in Figs. 2, 7, and 8. The awls are then operated by the plunger. When it is desired to drive the nails into the heel, the plate 0 ismoved into the guides A, and the plate 0, with its driver, into the guides N, the drivers being then operated while the awls remain at rest. The awls and drivers are thus made interchangeable.

It will be seen that as many awl and driver carrying plates may be employed as there are gangs of nail-holders in the bed B, the plates not'in use being held by the guides A or A Each gang of awls and its companion gang of drivers. corresponds in size with one of the gangs of nail-holders; hence the machine is adapted to as many sizes of heels as there are gangs of nail-holders. I

I prefer to couple together each pair of awl and driver holding plates by a bar, 13, which is provided with arms or studs 0 C, project ing through slots D D in the outer guides, A

l 8, so that they may be raised without binding on the plate O. The bar B is provided with a handle, F, which enables it to be moved back and forth. The slots D are of such length and are so arranged that they limit the movement of the bar B and the plate to the exact length required to bring one plate under the plunger 1, and leave the other at one side thereof, so that the plunger will not'bear on the plate which is to remain at rest.

A suitable locking device should be provided to engage each plate 0 or O with the plunger, so that when. the plunger is in motion the plate carried thereby will not be liable to accidental displacement.

T represents the jack on which the boot or shoe is supported. Said jack is pivoted at U to ears'on a slide or carriage, U", which is connected by a vertical pivot, U with a slide, U", and adapted to move horizontally toward and from the front of the machine between guides V, supported by avertically-rnovable frame or cross-head W, which slides in vertical guides at a, attached to the frame of the machine. 'The cross-head WV is provided with a vertical screw-threaded rod, b, projecting. downwardly, and entering a socket which is not threaded in a lower cross-head, W, which is adapted to slide in guides ca. The thread ed rod 72 connects the cross-heads NV and W, so that both will rise together when upward pressure is applied to the lower cross-head. The lower cross-head is provided with a j ournaled nut, 0, adapted to rotate in its upper end and receiving the threaded rod I). Said nut is formed as a gear-wheel or pinion at its "periphery, its teeth meshing with the teeth of a pinion, e, on a shaft, f, having a pinion, e, and journaled in suitable bearings on the frame of the machine, and rotated in either direction, as the operator may desire, by means hereinafter described, and thus rotating the nut or pinion c. It will be seen that the rotation of said nut or pinion in one direction will raise the rod 6, upper cross-head, V, and jack T, the lower cross-head remaining at rest,

I supported by a treadle, h, which is pivoted at i to the frame A. The shaft f or nut or pinion c are rotated by means of a counter-shaft, 7', journaled in bearings on the frameA, and having a pinion, c and two loose pulleys. 7a 7., driven in opposite directions, the one by a crossed and the other by a straight belt running on pulleys on a suitable drivingshaft. (Not shown.)

Between the pulleys is k is a friction-clut h, l, engaged with the counter-shaft j by a feather and groove, so that it rotates with the shaft, and is capable'of sliding, so as to engage'with either of the pulleys k. The clutch Z is operated by means of a fork or shipper, m, pivoted at n to a bracket on the frame A, and projecting into a peripheral groove in the clutchl, and a. lever, 0, rigidly attached to said shipper and extendingto the front of the machine, as shown in dotted lines in Fig. 1 its outer end being bent upwardly and provided with a handle, 1). It will be seen that by moving the lever 0 in one direction or the other the clutch Z will be engaged with one pulley k or the other, according to the direction in which the counter-shaft is to be roside of the operator to the other, as he stands in front of the machine, and not toward and from him.

q q represent lcverspivoted at 1- r to the base or support to which the jack is pivoted, and'adapted to oscillate in the same direction as the jack, said levers being at opposite sides of the jack, as shown in Fig. 2. The levers q q are provided at the inner sides of their upper ends with jaws or offsets adapted to bear against the opposite sides of the j ack or against a boot or shoe upper placed thereon. Against the outer sides of the levers q q bear rollers s s, journaled on slides ti, which are adapted to move horizontally between guides u a (see Fig. 3) aiiixed to theframe A. Said slides are moved simultaneously in opposite directions by means of a two-armed lever, c, pivoted at w to a fi'xed support, and connecting rods aa,connecting the arms of said lever, respectively, with the slide 25 and the slide t, as clearly shown in Fig. 3. When the lever 12 is turned in one direction, the slides t t are moved simultaneously toward each other, and their rollers are caused to press the levers q q against the jack or the boot or shoe upper thereon and force .the same to a central position-th'at is, to the exact position which the boot or shoe should assume with relation to the heel pricking and nailing devices before described. The weight of the lever 1; tends to ICO turn it in such direction as to press the levers q q against the jack; hence the latter is cen tered automatically, the operator grasping the lever only to remove the levers q g from the jack.

b I) represent jaws located above the-upper end of the jack T and its centering-levers q q. 1

. the proper position relatively to the nail-holders in the bed B and to the centered jack.

71 represents a top-lift spanker or plate pivoted to the rod D so as to swing horizontally thereon. Said plate is in contact with the under surface of the bed B, and is of such size as to cover a gang of nail-holders, as shown in dotted lines in Fig. 10. An arm, i, projects upwardly from the outer edge of the plate or spanker, and is bent over the upper surface of the bed, and provided with a block.

j, which serves as a bearing for the plunger I when a top lift is being applied, as described hereinafter. The spanker is provided with a handle, k, and with a spring-dog, Z, adapted to engage automatically with either one of a series of notches, m, in the periphery of the bed B, to hold the spanker in position for operation.

The operation of the above-described ma chine is as follows: The plunger I is first pro vided with an awl-bearing plate, 0, the toplift spanker is moved away from the gang of nail-holders under the plunger, a heel is placed between the jaws b b, and grasped by the inward pressure of said jaws caused by the gravitation of the lever d, the top lift of the heel bearing against the under surface of the bed B. The jack is moved out, as shown in Fig. 1, to receive the boot or shoe and is then moved inwardly, so that its heel-seat comes under the heel and is centered by the action of the levers q q and their operating-lever a, as above described, the jack being as yet dopressed so that the boot or shoe thereon is separated from the heel, the lower cross-head, XV, resting on a step or shoulder, 2, of the treadle-lever h. The operator now engages a depending dog, 0,whieh is pivoted to an arm, 1), on the upper crosshead, V, with a hook, g, on the treadle-lever 71, as shown in dotted lines in Fig. 1. The operator next, by a movement of the lever o, engages the clutch Z with the pulley 7.7, which rotates in the direction required to raise therod b and upper crosshead, XV, through the pinion-nut c and the described intermediate mechanism. Thecross-head W and jack Tare thus raised by the drivingpower until the heelseat of the boot or shoe is pressed firmlyagainst the heel, and the lat ter is compressed between the heelseat-and the bed B. \Vhile the jack and the cross-head \V are thus rising, the dog 0, by its engage ment with the hook q of the treadle-lever It turns the latter on its pivot, so as to bring a second step, 3, on said lever under the crosshead W, so that when the jack is raised as far as possible by the power applied through the counter-shaft (which fact is indicated by the slipping of the driving-pulley on the frie tion-clutch or of the belton the driving-pulley) the operator can, by applying his weight to the outer end of the treadlelever, turn the latter sufficiently to bringathird step, 4, on saidlever under the cross-head WV, thus giving both crossheads and the j aek an additional upward press nails are being driven.

that the plunger will not bear upon it.

me, which gives the heel a suitable compres sion The step 4 being new directly over the pivot of the leverh, saidlever has no tendency to turn on its pivot, and so supports the crossheads and jack, and maintains the compression of the heel. depresses the plunger I, causing the awls to pass through the nai1-holders and perforate the heel. \Vh en the plunger rises, a plate, P, with a gang of drivers, is slipped into the space between the guides U N of the plunger,- the plate P, with its awls, being at the same time removed. The nail-holders are neXt supplied with nails, preferably by means of a loader, such as is shown in Figs. 12, 13, and 14, the same being composed of a series of tubes, a-, set in plates h b", the lower ends of the tubes being normally covered by a sliding springplate, 0 perforated to coincide with the tubes a". The loader is supplied with nails and moved into a recess, d", in the upper surface of the bed B (the gang of nail-holders opening into the said recess) until the rear end of the plate 0 strikes the rear end of said recess and is arrested thereby, so that its perforations coincide with the tubes at", and allow the nails to drop into the nail-holders C. The leader is then removed, and the plunger is again depressed, the drivers being thus caused to drive the nails into the heel. The normal position in which the bed B is held by the spring H may be varied by means of adj ustable stops inserted in the frame A, and fornr ing bearings for the upper surface of the bed. The bed may therefore be adjusted so that the plunger in its descent will press the bed downwardly and compress the heel while the If such compression is not desirable, the bed should be lowered, so The plunger in its descent presses down the bed B, which it ermitted to yield by its spring H, and therefore presses the bed downwardly upon the heel and additionally compresses the latter while the nails are being driven. If the heel is to be supplied with a blind-lift, a part of the nails are allowed to project from the heel by shortening some of the drivers. The jack is lowered by turning the lever h on its pivot, so as to bring the lowest step, 2, under the cross-head. The blind-lift is then placed between the jaws b b, which before held the heel, and the top-lift spanker is moved to place between the top lift and the bottom of the bed B. The plunger Iis then forced down by the drivi ng-shaft; but the block j, interposed between the driver-holding plate at the bottom of the plunger and the upper surface of the bed B, prevents the drivers of the plunger from passing through the bed, as shown in Fig. 11, the downward pressure of the plunger being applied to the block j and through the latter pressing the yielding bed downwardly upon the heel, thereby pressing the blind lift The shaft K is now started and IIO firmly to its place on the heel, thejack being meanwhile rigidly supported by the lever.

" After this the plunger is raised, allowing-the bed B to bealso raised by its spring, and the jack with the boot or shoe is removed.

It will be seen that all the described operations-via, pricking and nailing the heel and applying the blind-lift-are performed with one jacking of the boot or shoethat is tosay, the boot or shoe remains continuously 011 the jack while all of said operations are being performed.

If desired, the nails may all bedriven entirely in, and the operation of supplying a blind-lift omitted.

The connection of the plate or carriage U supporting the jack, to the slide U, by means of the vertical pivot U enables the carriage U and the jack to be turned slightly on said pivot to adapt the jack to rights or lefts, a right boot or shoe requiring to stand at a slightly-differ-- ent horizontal inclination from a left boot or shoe.
