HEEL-'NAILI'NG MACHINE.

SPECIFICATION forming part of Letters Patent No. 502,669, dated August 1, 1893. Application tiled May27, 1.892. RenewedJune 16, 1893. Serial No. 477,866. (No model/ To all whom t may concern.- Y

Be it known that I, OHARLESLW. GLIDDEN,

of Lynn, county of Essex, State of Massachusetts, have invented an Improvement in Machines for Treating Heels, of which the followf ing description, in connection with the accompanying drawings, is a specification, like 'letters and igures on the drawings representing like parts.

In another application, Serial No. 432,167, filed on the 7th day of May, 1892, I have shown and described a machine having nail assorting and presenting mechanism to present nails into one of a series of nail boxes, r5 said nail boxes in turn presenting the nails carried by them into place between a heel seat die and a series of nail drivers so that a series of heel blanks are brought in succession intov co-operative relation to the nail boxes and nail drivers, and the latter then act to drive the nails from the nail boxes into the heel blank. The machine referred to is so devised as to operate on several heel blanks at the same time, but the operations 2 5 simultaneously performed by the machine and all tending toward automatically loading a heel blank with nails, dier.

In my aim to further improve and simplify machines for automatically assorting nails and loadingr them into heels, I' have devised the machine herein to be described, it containing a nail assorting mechanism which may and will preferably be the same as in my said application, but which may be of any other usual or suitable kind, said nail assorting mechanism, of whatever form, having however a series of roadways closed preferably at their lower ends bya suitable gate.v The machine further contains a support for a nailbox which is located at some distance below the gate referred to, and the space left be roadways are turned or moved aside from line with the main roadways 'and nail box and the drivers are brought into the position previously occupied by the said auxiliary roadways and the said drivers are actuated to drive the nails from the nail box into a heel blank Sustained below the nail box preferably then impaled upon a heel seat die mounted upon a suitable carrier which may and preferably 6o will be arranged to co-operate with suitable heel blank compressing mechanism which may be substantially as shown in my said application or of any other usual or suitable shape, it having co-operating with it or not asdesired a gang of awls for pricking the heel. Herein it will be noticed that the auxiliary roadways act not as nail carriers, but only as guides.

Figure 1, in side elevation represents a suf- 7o ficient portion of a heel blank machine which taken in connection with the machine shown in my application, Serial No. 432,167, referred to, suciently represents my present invention; Fig. 1, a detail of the block a2 and gate 75 as; Fig. 1b, an under side view of the gate. Fig. 2, on a somewhat larger scale represents a section below the dotted line Fig. 1, the auxiliary roadways being, it will be seen, in their inoperative position. Fig. 3, is a verti- 8o cal section of the part' shown in Fig. 2, together with some of the actuating devices for the driver, which devices are omitted from Fig. 2. Fig. 4, is a detail showing the auxiliary roadways'in their nail guiding position, the nail 85 drivers being turned into inoperative position. Fig. 5, represents a portion of the forward ends of the carriers to which are attached the blank compressors or dies; and Fig.

6, is a perspective view of one of the com- 9o pressors or dies detached.

To simplify the description of the machine herein to be made the subject ofA this specification, I will premise by stating that the framework A, the cam N, the shaft A4, the slide bar n', actuated by the cam N,the system of links and joints marked c4, c, c7, d, d', ce, the slide block O3, actuated by theV toggle d, d', the rotatable carrier D5,.the heel seat dies E,

` there being two such dies shown, their co-oproo erating impaling pins 15, their actuating lever 17, the gear D', the shaft A13, the pinion D2 splined thereon and loosely in engagement with gear D and rotating the said carrier and its heel seat dies; the rod E', the lever G pivoted at G2 and servingas a yielding abutment for the plate G through which descends the series of awls 37 to prick the heel blank, in case the said awls are used and if it is desired to prick the heel blanks, the awl-carrying slide 39, the link il jointed 'thereto and actuated by a crank on the shaft A4,the auxiliary crank 43, the driver bar 4G actuated by a crank pin 44 thereon, the rack e111-, made vertically movable with the said driver bar and engaging the toothed .rod 5l in bearing 52, said rod carrying a spider 53, the sector @12 actuated by said rack e111, the tubes 6 to lead nails into the roadways g?, the slide C rod a7 to reciprocate the slide, and roadways Q7, the devices sustained by the slide C and instrumental in asserting the nails and delivering them point first into the roadways g7, the lever E5, the notched disk A15 fast on shaft A13 and engaged thereby, the clutch pulley E7 its actuating belt E5, and the gear t8 on the lower end of the shaft A13, and lever A12, pivoted at A10, the nail boxf, the drivers, driver plate e and aligning pin e7, and the springf4 are and may be all substantially as in my said application wherein the same are fully described and illustrated. In the application referred to, the lower ends of the stationary roadways terminated in a plate. In this present invention the lower ends of the said roadways terminate in a block a2, which has co-operating with it as shown, a gate a5, said gate being acted upon by a spring a4, see Fig. la, which normally keeps the holes a5, see Fig. lb, of said gate,out of register with the holes in the block a2.

The driver plate e is adapted to be slipped into suitable guides at the under side of the driver carrying arm 195, preferably pivoted at 195, upon the driver bar, one end of the said arm, as herein represented, entering a slot or space in the lower end of the driver bar.

The nail boxf acted upon by the spring f4 is normallykept in such position that the nail holes in the said nail box are out of register with relation to the holes 93 in the support 92, but when the registering pin e7 enters the hole es, which it does just before the drivers enter the holes in the nail box, the said nail box is thereby moved so as to register its nail holes with the holes 93 in the said supporting plate, so that the nails acted upon by the drivers may be driven from the nail box directly into a heel blank then resting upon a heel seat die or support E, the blank being preferably held there as against lateral movement with relation to the die, by the impaling pins 15.

The supporting plate 92 is represented as connected with a standardb3 attach ed in suitable manner as by a set screw 1114 to the framework of the machine, said standard having as represented a horn 1917 which constitutes a pivot for the arm 1912 which carries the auxiliary roadways b2, said auxiliary roadways having their lower ends connected with the said arm and their upper ends connected with a suitable plate 1310, provided with a series of holes, the said plate, as herein represented having a pin or projection as 1912, which when the auxiliary roadways are put into operative position, or in the position represented in Fig. 4, strikes the gate CL3, referred to, moving the latter and permitting the nails, the points of which are sustained by the gate, to pass through the auxiliary roadways and be delivered directly into the holes in the nail box. This done, the auxiliary roadways are turned or moved aside by devices to be described, and the driver arm 195, having the drivers below it, is swung into position previously occupied bythe auxiliary roadways, and the driver bar is depressed causing the drivers to act and drive the nails from the nail box into the heel.

mental in carrying theseries of drivers, is

connected or jointed by a link d5 with the arm 1918 supporting the auxiliary roadways, and said arm 195 is also jointed by a lilik r11 with a slide bar d5 having its shank fitted to slide in a guide (Z5, said slide as herein represented having a cam-shaped slot C11 to receive `a crank pin d8 actuated by a shaft d provided at its lower end with a'gear C110, said :shaft being represented mostly by dotted lines in Fig. l. The gear (11 referred to is engaged by a gear t8 fast upon the lower end of the shaft A15, common to my said application, but herein the gear D2 at the upper end of said shaft is of but half the size of the gear D connected with the carrier D5 carrying the heel seat dies.

It will be unnecessary for me to herein describe the manner of rotating the shaft A13, further than to say that in practice it has mounted loosely upon it a continuous rotating pulley forming part of a clutch such as described in said application, the construction being such that by the movement of the lever E3 a clutch bar co-operating with the said constantly rotating pulley is brought into operative engagement with the said shaf t and made to rotate when the said clutch mechanism is by its own inherent construction thrown out of gear leaving the shaft at rest until the clutch is again manually or otherwise actuated to come into operative engagement. lt will be noticed that the pin h1 connecting the link d4 with the arm 195 is extended upwardly, see Fig. l, loosely through a hole in an ear of said arm, and so also the link (Z5 connected with the arm which carries the auxiliary roadways is extended upwardly loosely through an ear-in the said arm 195. These long pins provide for the vertical movement of the driver, yet maintain the operative connection of the slide bar with the arm 195, and the latter with the arm 1912 having the auxiliary roadways.

This invention is not limited to the particular mechanism represented by which to connect and to actuate both the driver arm,

IIO

and auxiliary roadway'arm in unison, and instead of the said devicesit will be apparent to any one skilled in the art that modified forms of connections might be employed without departing from this invention, thel gist of which so far as the auxiliary roadways, the drivers, and the nail box or the heelblank support are concerned, lies in the or'- ganization of the said separate elements in such manner that while the nail box occupies a i'ixed position with relation to the roadways of a nail assorting mechanism, the auxiliary roadways and the nail driving mechanism occupy a movable position so that one after the'other comes into operative position in the space betweeny the nail box or heel support and the main roadways the one to act simply as a guide for the nails in their final passage into the nail box or heel blank, and the other to thereafter drive the nails into the heel blank.

Herein as in the said application I have represented compressing jaws or dies hw for compressing the sides of the heel as the latter is being compressed in its height, and I have so devised and arranged the movement of these dies that duringtheir iinal operation upon the heel blank they act to crowd the heel breast against the fixed die or breast plate.

In practice there is a tendency owing to the great resistance of the leather to move the dies or compressors longitudinally upon the levers or devices which close them together. So to eitectually provide against this I have in this instance of my invention provided the dies or compressors with one or more shoulders or steps, as 71.12, see Figs. 5 and 6, which co-operate with similar projections or shoulders ot' the levers bl. The auxiliary road-way when put as described,temporarily inline with the holes in the main road-ways, may be madey to deliver the nails dropped into them directly into holes previously made in a heel blank; and such a machine would come within the scope of my invention, for it would contain the series ot movable roadways which I believe I am the iirst to use. Yet in another application I have shown a series of auxiliary roadways made removable from the machine to adapt the said machine to heels of difterent shape and size, but herein the auxiliary roadways are moved aside out .of operative position to permit the nails to be driven.

This invention is not limited to the particular form shown of nail driving devices as any other novel or suitable device for acting on the nails and driving them may be employed without departing from my invention.

I claim- 1. In a machine for treating heels the following instrumentalities, vizs-a nail box; a stationary series oi' main road-ways located and terminating at a distance above said nail-box; an independent auxiliary series of nail-guiding road-ways adapted to be moved alternately into and then out of line with the holes in the main road-ways and into and outl of the space between said main road-ways and nail-box; a series ot` drivers also adapted to be moved into and out of the space between the said main road-ways and nail-box, and actuating devices for effectingk saidgmovements of said auxiliary road-ways and drivers, to operate substantially as described.
