CHARLES W. GLIDDEN, OF LYNN, ASSIGN OR TO JAMES W. BROOKS, TRUSTEE,
OF PETERSHAM, MASSACHUSETTS.
HEEL COMPRESSING AND LOADING MACHINE.
SPECIFICATION forming part of Letters Patent No. 502,668, dated August 1, 1893.
Application filed January 3, 1893. Serial No. 457,094. (No model.)
of Lynn, county of Essex, State of Massachu-- setts, have invented an Improvementin Heel Compressing and Loading Machines, of which the following description, in connection with the accompanying drawings, is a specication, like letters and numerals on the drawings representing like parts. l
This invention has for its object to simplify and improve the apparatus shown in my application, Serial No. 432,167, filed May 7, 1892. In that application I have shown two rotary tables or carriers, one for moving a series of nail boxes, and the other a series of heel seat dies, and also a set of awls and a set of driv ers, the heel being pricked in a compressing die and being thereafter carried by the heel seat dies in line with the loaded nail-box and the drivers. In this present invention l have dispensed with the series of heel seat'dies and their rotating carrier, and with the awls for pricking the heel, and instead I deposit the heel to be illed with nails from the automatically loaded nail box, upon a heal seat die mounted upon a rising and falling die plunger, the latter effecting the placing the heel blank in a heel compressing die adapted to compress the heel from edge to edge, and at the same time the heel seat die in its vertical movement co-operates with a yielding or other abutment and compresses the heel vertically. This vertical compression of the heel, however, is effected against the bottom of the table or carrier 'upon which rests the loaded nail boxes, and the drivers, connected with a suitable driver bar, drive the nails directly from a nail box into a heel, this being practical in many classes of heels now used. In this present invention I have provided the driver-bar with a suitable rack or projection to actuate, at the proper times, mechanism for automatically assorting and distributing nails into the nail boxes, the nail assorting and distributing mechanism being substantially the same as in said application. During the operation of driving the nails from the nail box into a compressed heel, the drivers descend through a guide plate, which is held pressed iirmly down against the nail box during the heel compressing and nail driving operations, but when the carrier for the nail boxes has to be moved this driver guide plate, performing the function of. an abutment, is slightly lifted to thus free the nail box from the friction of the plate, in order that the nail box and carrier may be moved freely with the minimum of power.
The peculiar features in which this invention consists will be hereinafter more fully described and pointed out in the claims at the end of this specification.
, Figure l of the drawings in side elevation, showsa sufficient portion of a heel compressing and loading machine to enable my invention to be understood; Fig. 2, a partial front or left hand elevation of lthe machine shown f in Fig. 1,' but with the nail assorting and distributing mechanism removed; parts of the devices being in section to better illustrate the construction and operation of the machine; Fig. 2a, a detail of the lower end of shaft A13. Fig. 3 is a partial section in about the line x, Fig. 2, the rack for actuating the nail asserting mechanism, together with the parts at the lower endof the shaft supporting the nail box carrier being omitted. Fig. 3 is a detail showing the guide-plate detached. Fig. 4 is a partial section below the line x,`Fig. 2. Figs. '4a and 4b are details of the parts connected with the lower endof the shaft A13. blank feeder in plan; Fig. 6, a longitudinal section thereof, and Figs. 7 and 8 are sections respectively in the lines mgl-.00, Fig. 5.
Referring to the drawings, A represents portions of the frame-work, the same being of any usual or suitable shape to sustain the working parts, to be described. The main shaft A', its pinion A2 engaging a gear A3;
'the shaft A4 on which the gear A3 is loosely mounted, said shaft having two cams B, N, and a crank pin 42; the shaft ne rotated in some suitable manner and provided with au eccentric to reciprocate a link nl; a/nail as- Fig. 5 isa detail showingthe heel toothed shank 51 attached to part of the nail assorting mechanism; the jaws b7 pivoted at bs and carrying at their front ends the side compressors b9, represented chiefly by dotted lines in Fig. 4,saidcompressors beingshown as attached to the levers by pins at x1; the lever vgpivoted at r and actuated by the cam B, said leverbeingjoined at its lower end, by suitable toggle jointed arms, with the rear end of the levers D7; the lever Gr', pivoted at G2; the rod Gr5 pivoted to the right hand end of the lever G and extended through a' spring G3 to normally keep the front end ot' the lever G pressed toward the top of the side compressing dies with a yielding pressure determined by the screw G7; the elbow lever A7 to control the time of engagement of a suitable clutch with the constantly rotating gear A3; `the link A8 connected to said lever A7 and to a hand lever A9, pivoted at A10 and extended forwardly and provided with a hand piece and with a point A12 to engage at propel-time and restrain the rotation of a plate A15 fast on the shaft A13; the lever Ff1 co-operating with said clutch plate; the slide a actuated by the cam N and connected by a link c4 to a toggle lever c, c7, shown by dotted lines in Fig. 1; the elbow link c8 jointed to the toggle d, CZ', the member cl of the toggle being pivoted at cl2, while the member d of the toggle is pivoted to the shank of the plunger or die-carrier O3. the pulley E7; the lever t2, t5; the spring t7; The belt EG to rotate the pulley E7 continuously; the link 41 surrounding the crank-pin 42; and the breast-plate 32, see Fig. 3, are and may be all substantially as represented in said application, wherein the same letters are used to designate like parts, so that said parts need not be herein further specically described. There is a slight difference, however, in the shape of the lever E3, a portion of the upper end of the lever being omitted from this present case, and herein the plunger C3, instead of carrying a plurality of heel-seat-dies, has fixed upon its upper portion a heel-seat-die E having suitable holes for the reception of suitable impaling pins 15 attached to a block 17 having a vertical movement by or through a suitable lever 0 pivoted on the block c3 and forked to embrace a Jin of the block 17. The outer end of the leve 9 enters a slot 12 in a bar 13 suitably attached to the frame-work, so that as the block C3 is lifted by straightening the toggle d, d', as provided for in said application, the lever 9 meets a portion of the bar 13 and is lnoved to force the impaling pins 15 into the heel then lying upon the heelseat die, the said pins aiding in withdrawing the compressed heel from the mold at a suitable time. The shaft A13, common to the said application, is provided at its upper end with a carrier 300 suitably chambered to receive nail boxesf provided with suitable nail holes 91, and with a positioning hole es for the reception of a positioning device e7 carried by a driver-bar 301. The said mailboxes are normally acted upon by springs f4, which in their normal position keep the nail holes in the nail boxes ont of line or register with the holes 3G in what I denominate the templet plate f forming part of the carrier 300 and upon which rests the lower sides of the nail boxes. These nail boxes, the templet, the rotating carrier, the means for rotating the shaft A13, and the positioning device c7 are and may be substantially as in said application. The positioning device e7 by its pointed end entering the hole e8 in the nail box, moves the nail box against a spring f1 to bring the holes 0l therein in line With the holes 36 in the templet, so that the drivers 302, connected with the driver-bar 301, in turn connected with the link 41 by the pin 40, may act upon the nails which are loaded automatically into the nail box through the nail asserting mechanism, and main and auxiliary road-Ways, as provided l'or in said application, and drive the said nails directly from the nail box into the heel then held in the compressing die, the upper or tread end of the hecl being pressed :firmly against the templet, the top side of the nail box being acted upon at such time by the guide plate 304, it having a series of holes, seeFig. 3, to receive and guide the drivers, and at the same time the said plate acts as an abutment to rest upon and hold the nail box and templet down firmly while the heel is being compressed vertically, the templet at such time constituting, it will be obvious, the upper side of the compressing mold, the side or edge compressing die being closed upon and acting to compress the heel from edge to edge, and from its rear side toward its breast intime and order substantially as provided forin the said application. The guide plate 304 has three side walls and an open side, as best represented in Fig. 3, two of its sides at its interior being provided with like notches 306, adapted to receive snitable projections 307, see Fig. 2, extended laterally therein from the driver-bar near the lower end.
In the application referred to, and as herein provided for, the spring G3 normally acts to keep the front end of the lever G pressed down in a yielding manner by a measured force, and herein the front end of said lever bears normally upon the side walls of the plate 304, but owing to the fact that the carrier 300 in its intermittent movements is brought into the space below the plate 304, it becomes necessary, in order to avoid friction, to lift the plate 304 when the said carrier is to be moved, and this is provided for by the projections 307 on the driver-bar entering the notches 306, the said projections during the last part of the upward movement of the driver-bar meeting the upper ends of the notches referred to in the walls ot' the plate 304, thus lifting said plate or abutment bodily from contact with the nail-boxes.
Herein I have provided means to positively lift the front end ol' the lever G while the driver-bar is lifting the guide-plate 304. To
IOC
IIO
do this I have provided the wheel A3 witha cam projection 207, see Fig. 1, which acts on a cam roll 208, mounted in suitable ears on the rear end of the lever G.
The driver-bar, as herein shown, has connected to it at its front side a rack 209 which engages the sector e12 to effect the operation of the nail asserting mechanism.
I have herein provided means for automatically feeding a heel blank into position over the heel seat die when the plunger carrying the said die is depressed, or when the toggle d, d', is not straight.
The constantly rotating pulley E7 referred to, formsppart of a clutch device, and, as also provided for in said application, it acts as a double clutch, that is, it actuates` the clutch part w to control the times of rotation of the shaft A13, and at its lower side it actuates al clutch part t loose with relation to the shaft A13 and having attached to it a cam 312, the said cam being kept on said shaft by a suitable pin or projection entering an annular groove 317, see Fig. 2, in the shaft' A13 at its lower end. This cam 312 receives in its groove a suitable roll or stud of a lever313, pivoted at 314, said lever having at its upper end a link 315, jointed at 316 to a carriage 317 X having a pusher 318 made adjustable on said carriage by a suitable adjusting device 319, which may be a screw, so that the pusher may be adapted to heels of different sizes. A spring 320 is attached to oneend of the carriage and at its other end to a heel blank support 321, the heel blank being laid upon the said support and against the said pusher, said support sliding upon a slotted plate or guideway 322 attached to a suitable stand 323 fixed to the frame work. The carriage 317 X is moved by the cam 312 in a direction to push a heel into position above and upon the heel seat die, when the latter is in its lowest position, and in the operation of the carriage in feeding a heel blank into working position. The heel support 321 and carriage 317 X move substantially in unison until the end of said support meets a suitable stop, which may be a portionof the heel seat die, and thereafter the support remains at rest While the carriage and pusher continue their movement to push the heel blank from the support into position upon the heel seat die to be elevated thereby at the next rise of the plunger C3, the said die putting the blank into the space between the open side compressing dies carried by the jaws 57.
Referring to Figs. 6 to 8 it will be seen that the heel blank support is composed of separate side pieces made adjustable toward and from each otherby suitable adjusting devices 325, herein shown as right and left threaded screws.
This invention is not limited to the exact shape of the pusher or to the exact manner shown of connecting it with the carriage, and it is obvious that the said pusher may form an integral part of the carriagev and that as an equivalent of adjusting the pusher or the carriage, the `link 315 may have a right and left adjusting nut 336 as shown in Fig. 2.
In the production of boots and shoes, the heels thereof are generally applied automatically in a heel nailing machine, the heel blank vbeing previously prepared for the nailing machine in various different ways( The heel blanks are composed of lifts brought together in a suitable mold, and thereafter the blanks are pricked for the reception of nails, and the nails are loaded or inserted in the pricked holes by suitable drivers.
In all machines for compressing and loading heel blanks for heel nailing machines, the blank has always been pricked by awls to thus prepare it for the reception of the nails to be, loaded therein.
In the machine herein described it will be noticed that the pricking of the blank is dispensed with and that the nails are driven directly from the nail box into the compressed heel, the machine containing Vsuitable compressing jaws to co-operate with the heel seat die and hold the blank on all sidesduring the loading or driving operation.
Having described lmy invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a machine for treating heel blanks, the following instrumentalities, viz :-a vertically movable plunger havinga heel seat die adapted to mold the heel seat end of the heel blank; a vertically movable driver bar having a series of drivers and a driver guide plate, both arranged directly above the said heel seat die; and a rotatable carrier having a series of nail boxes or holders adapted to be brought in succession into the space between the said heel seat die and driver guide plate whereby a heel blank after having been compressed vertically and While the carrier yet remains in the position in which the heel blank was compressed vertically, may have nails driven directly into it from-the nail box ,or holder then inl position, substantially as described.'
2. In a machine for treating heel blanks, the following instrumentalities, vizz-a vertically movable plunger having a heel seat die to mold the heel seat end of a heel blank; ak
`vertically movable driver bar having a series of drivers, and a yielding abutment, the said drivers being arranged directly above the said heel seat die;y and a rotatable carrier having a series of nail boxes or holderswhich are adapted to be brought one after another into the space between said heel seat die and abutment, whereby a heel blank may be cornpressed vertically, and while yet in the same position have 4a series of nails driven into it from the nail box or holder, substantially as described.
3. In a machine for treating heel blanks, the following instrumentalities, viz:-jaws to compress a heel'blank from edge to edge, a vertically movable plunger having a heel IOO seat die shaped substantially as described to mold the heel seat end of the blank and 1ocated directly in line with the space between said edge compressing jaws; a vertically movable driver bar having an attached series of drivers, and an abutment, the said parts beinglocated at the opposite side of the space between said edge compressing jaws, and a rotatable carrier having a series of nail boxes or holders, and means to move the same, wherebyT the said nail boxes or holders may be put successively in position between the said abutment and drivers on the one side and the said edge compressing jaws, and means to actuate the plunger carrying the heel seat die to project a heel into the space between the said jaws and compress the same while the nail box or holder is in position under the abutment and nail drivers, to operate, substantially as described.
4. In a machine for treating heels, the following instrumentalities, viz:-a reciprocating driver-bar; a series of drivers, a heel seat die,andavertically movable plunger on which it is mounted, combined with an intermittingly rotatable carrier having a series of nail boxes, which are put in succession in the space between said drivers and heel seat die, edge compressing jaws, and a yielding guide plate to co-operate with the heel seat die du ring the vertical compression of the heel blank, substantially as described.
