SHOE=SLUGG|NG MACHINE.

SPECIFICATION forming part of Letters Patent No. 487,404, dated December 6, 1892. Application iiled July 1l, 1892. Serial No. 439.719. (No model.)

To all whom t may concern.-

Beit known that I, SOLOMON MAROELLA CUTTER, of the city of Quebec, county and Province of Quebec, Canada, have invented certain neW and usefulllnprovements in Shoe- Slugging Machines; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to machines for au- Io tornatically supplying loose nails from a reservoir or hopper to a nail-guiding throat from which the nails are driven by a reciprocating driver, and has for its object to provide a more eiicient, durable, and less-complicated l5 machine than has hitherto been produced, and, further, to provide a novel and improved vstock-feeding device which coacts With the slugdriving parts to secure the better inser tion of the slug. zo The invention consists in the several improvements Which I will now proceed to describe and claim.

In the accom panying drawings, forming part of this specification, and in Which like sy1nz5 bols indicate corresponding parts, Figure 1 is a left-hand side elevation of the head portion of a machine embodying my invention; Figs. 2 and 3, respectively side elevation and plan views of the raceway; Fig. 4, avertical transverse section of machine on lineman, Fig. 1; Fig. 5, a front or face view of the head portion ofthe machine; Fig. 6, a detail face view of one section of the cam-roller for operating the race- Way, a portion of the lever being also shown in elevation; Fig. 7, aside elevation, partly broken away, of the same section of cam-roller; Fig. 8, a detail sectional view showing cams and lever connections for operating the feed; Figs. 9 and 10, detail sectional views of the 4o slug-receiving or throat portion of the head of the machine and showing the feeding end of the raceway respectively in its forward and backward positions and the slug-holder and slide in cross-sections. Figs. l1 and 12 are face views, partly in elevation and section, of the same parts as shown in Figs. 9 and 10. Fig. 13 is a horizontal section of the front portions of the head on linee'z, Fig. 12; and Fig. 14 is a right-hand or reverse side elevation of the head portion of the machine shown in Fig. 1.

A is the upper end of the standard or pedestal ot' the machine, its lower portion not being shown, as my invention is confined solely to the parts carried by the head portion or frame B, which is bolted to it.

O C O2 are vthree standards formed in one with or secured to the frame B and projecting up from it, those O C2 at opposite ends to carry the driving-shaft D and the other O' 6o centrally to carry the lever for operating the slug-driver.

The shaft D has mounted upon it the iiy- Wheel D' and fast and loose pulleys D2 D2, a cam E for operating the slug-driver, a double cani E E2 for operating the Work-feeding mechanism, a pulley F, from which a rotating nail-reservoir F', of any usual construction, is Worked by bandf, a grooved roller G for operating the raceway, and a cam Q for 7o operating the combined slug holder and releaser.

The slug-driver II is of the usual form and secured to a cross-head or dovetailed plate I-I', Working in a vertical guideway formed by 75 face-plates H2 H2, screwed to the standard C2,

a positive up-anddown motion being imparted to it through a lever J, pivoted in an arm C2, extending from the standard O and having its inner end forked to connect with 8o a block J', which is arranged to slide :in vertical guideways in the standard O2, and to carry a rolierj, which works in the groove of the cam E, the leverJ being connected at the other end bya link J2 with the cross-head H'. 85

H2 H4 are additional faceplates covering the operating parts inthe lowerportion of the standard O2, that H4 forming one side of the vertical throat for the slugs.

The raceway along which the slugs travel 9o from the reservoir F' is constructed and operated to conduct the slug to a position immediately above the vertical throat ornail` tube O and in the axis of the slug-driver and its construction may be thus described: It is formed of a solid inclined bar K, having a base block or foot K', provided with dovetail flanges 7c to fitcorresponding guidouays lo' it', formed on the base-plate of the frame IB and to slide to and fro therein, the bar being roo' grooved centrally' in its upper surface to afford a passage-Way K2 for the slug-bodies.

Two adjustable cover-strips 7a2 k2 are set on the bar K the required distance apart to support the slugs by their heads while allowing them free passage, and these strips project forward beyond the lower feeding end of the raceway-body, so that when the raceway is moved forward the slug at the eXtreme end will be located directly over the throat and beneath the driver.

A yielding slug-releaser in the form of a lever L, bent so that one portion will lie fiat on the upper surface of one of the cover-strips 7a2 and present a pointed iingerl across the extreme end of the raceway-passage and another portion turn down over the side of the raceway and receive the pressure of a coiled spring l against its end, is pivoted at L to the top of the cover-strip 7a2 and has a downwardly and forwardly projecting ear or lug Z2, by means of which an extension from the slug-holder coming in contact. therewith, as will be hereafter explained, can free the lower most slug. An adj ustable protector-strip M, extending about half-way up the raceway, is also attached thereto, as shownin Figs. 2 and 3, to prevent the slugs jumping out.

The forward movement of the raceway is effected by means of a lever N, pivoted at n to a bracket N', projecting out from the rear of the standard C2 and having one end pivotally connected at n with the raceway and the other end carrying a roller n2, working in the groove of the roller G, the construction of which roller I will now describe. It is preferably composed of two halves g g, one of which has the sleeve portion G2, required for securing it to the shaft, formed in one with it and the other half being secured to such sleeve portion. The inner faces of these halfsections are correspondingly shaped to present an inclined groove or guideway, the rotation of which will impart reciprocal movement to the lever N, and in addition to this a number of adjustable studs g2 g2 are screwed through the section g, as shown in Figs. 6 and 7, so that their ends will project laterally into the groove and produce a shaking or tremulous motion in a longitudinal direction in the raceway at the proper time for the delivery or release of the lowermost slug.

lReferring now to Figs. 9, l0, ll, l2, and 13, the slug-holder proper consists of 'the bar or nger P, which is an extension from the plate S, working horizontally in from the side of the head B, the lever-arms P P2, pivoted in the bearing P2, and the cam Q being its operating mechanism, and such bar holds the slug firmly between its end and the block p, forming the upper portion of the right-hand side of the throat. The holder P is yieldingly connected with the lever-arm P2 in order to accommodate different sizes of slugs by means of an arm P4, projecting from the lever-arm P2, a stud s and slot s in the plate S, a rod s2 with one end pivoted to the end of the plate and the other passing through a hole in the bent end of the arm P4, and a coiled expansion-spring s3, acting between the end of the arm P4 and the pivoting-shoulders of the rod s2.

S' is the extension from the finger P, but out of line of the slug-driver and slug and moving in front of Sallie for the purpose of operating the yielding slug-releaser or lever L, as before described.

The feeding mechanism consists of the vertical awl V, formed on the inner end of a horizontal shank or slide V, carried in a groove 1; in the foot portion V2 of a bar V2, located in an inclined guideway or passage-way V4 in the framework-head B, which gnideway is wider than the bar in order to allow of a slight lateral movement of the bar therein, as will be more fully explained in the operation of the machine. The upper end of the bar V3 is attached to the free end of an arm V5, fixed by set-screws v o on the forward end of a shaft V6, running parallel with the main driving-shaft D and being carried at front and rear ends, respectively, by an arm c, projecting from standard C2, and an arm or extension c from the standard C. The shaft VG is encircled for the greater part of its forward length by a sleeve-W, as shown in Fig. 14, and on this sleeve are lixedly set, first, an arm W, carrying at its lower end a pusher bar or rod W2 for acting on the foot of the bar V3, as will be fully explained hereinafter, and such arm W being connected with said bar V3 at its lower end by retractile spring W3; secondly, a collar W4, to which is attached one end of a spring W5, coiled around the sleeve between the collar and the arm c and to which latter its other end is attached, and, thirdly, an arm V, tixcdly set in place and carrying a roller w on its free end to bear on the periphery of the part E of the double cam E E2, a second arm V7 being lixedly set upon the shaft V6 beyond the end of the sleeve W and carrying a roller o" on its free end to work in a cam-shaped groove e2 in the part E2 of the double cam E E2.

When the raceway is in its forward position, as shown in Fig. 8, with the slug directly over the throat O, the holder P through leverarms P P2 and cam Q is thrown forward to grip and hold it fast between its end and that of the block p, and the slug is freed from the releaser or finger Z by the extension S' having moved such a stop out of the way of the slug, so that it only remains to withdraw the raceway, which is done by means ofthe groove of the roller G, which acts through the lever N to draw the raceway back a sufficient distance to free the slug from its end,leavingit held between the holder P and the block p when the driver T descends to drive the slug down the throat into the work, the indentation in which latter caused bythe feedingawl facilitating the entry of the slug.

While the slug is being driven the awl V forms the lower right-hand side portion of the throat O, as shown by the dotted lines in Fig. 11, and simultaneously with the upward movement of the driver T the awl moves in a IOO ITO

right-hand direction to the required point over the work where the next slug is to beinserted, and it is then driven down into the work and by a left-hand movement carries it to its position under the driver T, after which it is withdrawn from the work, leaving ahole for the reception of the slug, and takes the position shown by the dotted lines to form the lower portion of the right-hand side of the throat O, as before mentioned. This motion of the awl V is secured by the contours of the earn E', (acting upon lever W5, sleeve W, arm YV', and pusher-rod W2) the groove e2 in cam E2, (acting through lever V7, shaft V6, arm V5, and bar-V3,) and the springs VV3 NVS, the spring VS serving to draw the bar V3 in the required right-hand direction (the rises 2 and 3 of the cam E being arranged to regulate the several movements) and the spring V serving to hold the roller on arm W(i against the periphery of cam E. An adj usting-screw w3 in the framework-head B is used to regulate the spacing of the slugs in the work by stopping the right-hand movement of the bar V3 at different points. The spring W3, in combination with the vertical surface or notch Y on the side of the bar V3 and the adj listing-screw w3, also provides that while the bar is in an inclined position the downward movement of the awl V shall be perfectly vertical.
