HEELlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 510,012, dated December 5, 1893.

Application filed December 24, 1892. Serial No. 456,274- (No model.)

T0 at whom it may concern:

Be it known that I, ALVIN D. ELLIOTT, of Lawrence, county of Essex, State of Massachusetts, have invented an Improvementin Heeling-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and numerals on the drawings representing like parts. i

This invention has for its object the production of a novel mechanical organization for attaching heels to soles, the apparatus being also adapted for applying a top lift to the tread end of a heel, this invention being an improvement on that described in application Serial No. 453,641, filed on the 30th day of November, 1892. In the application referred to, the driver, as well as the templet and-its carrier, is actuated by springs released in succession during the attaching of a heel to a shoe, but the said driver-bar and templet are shown as located above the shoe support, and the latter is shown as actuated by a manually operated treadle or lever.

In this my present invention I have devised novel mechanical devices and have organized them in a power machine whereby the different or successive steps of attaching a heel and providing it with a top lift if desired, are carried out automatically, and in this machine I have devised devices for automatically moving theshoe holder into position to insure not only a firm contact of the sole with the seat end of the heel to be nailed to it, but also to suitably compress the material of the heel prior to the heel attaching operation, the devices for operating the shoe shoe support being, however, locked firmly in position during the driving of the nails,

the position atwhich the said shoe support is so held locked varying according to the height of the heels.

This invention is, it may be considered, also animprovementuponthatcontainedinUnited States application Serial N 0. 441,020, filed on the 23d day of July, 1892, wherein the provision for self'adapting pressure to the heel is broadly claimed.

Figure 1 is a right-hand side elevation of a heeling machine containing my improvements. Fig.2 is a partial front elevation of the machine shown in Fig. 1; Fig. 3, a partial section in the line on Fig. 1. Fig. 4 is a section on the line X Fig. 2. Fig. 5 is a top or plan view of the uppermost parts in Fig. 3. Fig. 6 is a partial rear side view of the machine shown in Fig. 1; Fig. 7, a partial section in the line sci-Fig. 6. Fig.8 is a section in the line on, Figs. 1 and 'i.

The frame-work A is and may be of any usual or suitable shape to sustain the working parts.

The Walking beam A pivoted at A the spindle A to which it is jointed, said spindle sliding in a bearing A the last slide A and its shoe holding post A, the clamp A for the rear part of the shoe, and the devices for adjusting said clamp, are and may be all sub stantially as in United States Patent N 0. 446,383, dated February 10, 1891.

The power shaft B has mounted loosely upon it a constantly rotating pulley B, it in practice, being part of a clutclnsubstantially such as employed on the main shaft in United States Patent No. 415,670, dated November 16, 1889, said clutch beingunder the control of a treadle B and a pawl E the removalof the pawl from the stop lug B of the clutch efiecting the engagement of the clutch with and so as to rotate said shaft.

While it is preferred to useaHorion clutch for simplicity and certainty of operation, yet any other usual or suitable clutch pulley may be used instead and yet be within the scope of this invention.

The power shafthas a suitable eccentric B surrounded by the strap of a link B jointed at its end at 2 to a cam device B represeuted as pivoted at 3 on a fixed part of the framework. This cam device, see Figs. 2 and 3, is represented as having two similar acting faces to contact with preferably rolls ct, carried by a pin a. mounted in the upper end of a slide a shown as a pin sliding loosely in a suitable bearing or socket in the frame. This slide is extended through a orosstail a having attached to it suitable rods a extended through, as herein shown, adjustable bearings a in lugs a forming part of the framework, said rods above said bearings passing through strong spiral springs ed, the upper ends of the springs made adjustable as to their effective strength by the nuts a acting against shoulders or collars a on the rods, the said springs normally acting to elevate the rods and with them the cross head a which in practice is suitably shaped to receive and sustain the templet a Just below the cross head a", the rods (1 are provided with depressing devices Inherein shown as hubs mounted loosely on said rods and having fingers 4, and arms 5, said arms being connected by a suitable springer actuator 12, said depressing devices, as herein devised, being made movable so as to permit the release of the driver-bar when the drivers are to act.

The front part of the frame-Work has suitable bearings, best shown in section Fig. 3, the upper bearing receiving and guiding the upper end of a driver bar I) having mounted upon it a suitable receiver b for the driver plate I) having a gang of drivers 5 adapted to rise through holes in the templet and act on and drive nails from said holes so that their point ends protrude through the heel b resting on the templet and enter the heel end of the sole b of the shoe 12 held in usual manner on the shoe holder or post A The driverbar having been extended through a suitable actuating spring I)", has its lower end extended through a tubular nut b which as shown constitutes not only a bearing for the said bar but also an adjusting device for the spring 13*. pressing devices I) referred to, see Fig. 3, have near their ends downwardly projecting lugs provided with semi-circular notches, the fingers near the lugs being adapted, in the descent of the cross head a under the action of the cam device B to act on the receiver b to thus depress the driver bar and compress its spring b During the operation of depressing the driver-bar the lugs referred to enter notches c in the frame A, and the semi-circular notches of the lug embrace trip rods 0 extended horizontally through suitable hearings in the frame, one of the ends of said trip rods being embraced by cases 0 inclosing springs 0 one of which is shown by dotted lines Fig. 4, said springs at one end acting against a suitable shoulder 6 on the rod, the other end of the spring being seated on the case, so that said springs normally act to keep the ends of the pins out in the position shown in the drawings. These trip pins are for a short distance reduced in diameter where they are embraced by the lugs of the fingers 4. The fingers having acted as described to depress the driver-bar, will hold said bar depressed until the fingers are moved by the trip pins to release the driver-bar. This is done in the following manner: I have mounted upon the' frame-work at d a trip-lever d, the lower end of which is borne by the springs a against a trigger cl pivoted on a pin d of a depending The under sides of the fingers of the destand 01 properly secured to the frame-work. The trigger, as represented, has a crank arm 7 jointed to an eccentric strap (1 embracing a suitable eccentric or equivalent device d on the main shaft B. Thelower end of the trigger has co-operating with it a spring e which acts against a latch e mounted on the pin d and provided preferably with a roll 6 to engage the cross-tail when depressed, and thus constitute a locking device to retain the cross-head and its templet depressed with the springs a compressed. The lower armof the trigger has extended through it a stud 6 which is extended through an opening in the said locking device and is thereafter provided with a cross-pin 8. Let it be supposed that the cross head and driverhave been partiallyjdep ressed, the mechanism being left in such condition whenthe machine was stopped after its cycle of operations, the stopping being for the purpose of enabling a heeled shoe to be removed and another shoe'to be heeled to be put into place. In this condition, the last slide and shoe are substantially in their highest positions. the templet aheel preferably previously loaded, will put his foot on the treadle and release the clutch to start the shaft 13*. This will cause the cam device to be moved, see Fig. 1, to the left and effect the complete depression of the cross-head with the templet,

The operator having applied a heel to.

and willfully compress the templet springs a in order that they may at their subsequent expansion spank on a top lift, and during the descent of the said cross-head the driver will be fully depressed and its spring compressed, and the trigger, drawn at its lower end toward the shaft B will by the spring e cause the locking device e to engage the cross-tail. During the descending operation of the cross- .head of, a suitable eccentric or equivalent f,

shown by dotted lines Fig. 1, will act through the eccentric strap f to elevate the same and cause a slip device thereon to act and elevate the rear of the walking beam, thus depressing the post A and the shoe to effect the placing of the heel end of the shoe against the seat of theheel, the pressure exerted being sufficient to resist the impact of the nail drivers on the nails when driving the nails into the shoe. During the movement last described, or while the shoe is being clamped or pushed against the heel, the trigger link 11* is moved in the direction of the arrow thereon in Fig. 1 and the pressure alluded to having been attained, the trigger in its movement with said link acts'against the permitting it to be actuated by a quick blow to drivethegangof nails into theheel and shoe.

This done, the devices for operating the walking beam in their continued action lift the last post A and remove the attached heel from the templet, the head ends of the nails slightly protruding from the tread end of the come into position between the heel and the be employed for that purpose.

templet, and now to spank the topdift onto the nails at the tread end of the heel, the templet carrier must be released. To do this, the

shaft A in the mean time has moved sufficient-ly through its cycle of motion to push,

the link d in the direction opposite the arrow in Fig. 1,and in so doing, the pin8 acts against the locking devicee and removes itfrom the cross-tail, thus tilting the springs 0. out to throw the cross-head and templet upward to effect the spanking operation. In the continued movement of the shaft, the stop-lug B is arrested by the pawl B and the clutch device is disengaged and the machine is stopped in the parts in the position Fig. 1.

It will be remembered that the driver-bar descended first, and then the crosshead, and as the cross-head was raised the fingers 4 of the depressing device rising in unison with the cross-head, are by the spring I) again turned into position to catch onto the receiver 19 in the first partial descent of the cross head in effecting the separation of the templet from the tread end of the heel preparatory to removing the heeled shoe. In the machine herein described the movement of the driver-barin the direction to compress its actuating springis dependent upon the movement of the cross-head carrying the templet.

This invention is not limited to the shape or number of springs used to actuate the templet carrierand templet.

The cross tail-rods and cross-head constitute what are designated as a templet carrier.

The trip pins 0' constitute releasing devices for the depressing devices I), but this inven tion is not necessarily limited to the exact construction shown for the releasing device, as any usual or suitable equivalent device may The spring m acts normally to keep the outer end of the treadle 13 elevated.

Referring again to the link f, it has at its upper end a box or enlargementf chambered for the reception of a cam ringf fixed in the box and provided at its interior with aseries of cam surfaces, shown best in Fig. 7. The cam ringf 'receives Within it the ring-like hub f of a lever f, the said hub being cut through at intervals, herein supposed to be cut at three places to form spaces for rolls f". The box f supports loosely a cylindrical nut f said nut being loosely surrounded by the hub of the lever f the nut engaging the threaded portion of a steep screw h, pivoted at 7d on a link 7L2, in turn pivoted to the walking beam at its rear end.

The lever f and rolls constitute a clutch to, at the desired times, grasp and prevent the rotation of the nut f the nut being grasped when the link f is to positively move the walking beam or shoe carrier, to eEect the positive pressure on the heel preparatory to driving the nails.

The parts carried at the opposite ends of the walking beam are of such weight with relation to each other and the fulcrum of the beam, that when a shoe is applied, the overbalanced front end of the beam has a tendency to descend, and the first part of this descent is aided by the friction of the rising nut f on the screw it, the nut itself being then restrained as to its free rotation by only its friction against the box.

The leverf is kept in place in the box f by a suitable cover m, and a spring m',one end of which, see Fig. 7, is attached to the lever, and its otherend to an arm m of the cover,acts normally to move the clutch in the direction of the arrow Fig. 7 to effect the grasping of the nut. The clutch is, however, for the most part of the time, held out of its operative position by a suitable latch m pivoted upon a latch-carrier m, shown as a slidebar, frictionally held in boxes m attached to the link f.

The latch-carrier has an ear m through which is extended loosely a releasing device, shown as a rod m said releasing device being represented as pivoted at its lower end to a stand m attached to the frame, said rod having as part of it a nut or collar on which in the ascent of the link f and the carrier on, arrests the ascent of the carrier and effects the release of the clutch to enable the spring m toinstantly operate the clutch and restrain further rotation of the nut f this releasebeing effected after the heel seat end of the sole of the shoe and the seat of the heel have been put together with the desired preliminary pressure. The latch referred to has pivoted upon its long arm (see Fig. 1) a rod n provided with a collar 72, the lower end of the rod being extended through a hole in a fixed ear n and below the said ear the rod may have if desired a collar Fig. 1 shows the shoe as applied to the shoe holder and with the parts in position to start the machine, a heel resting upon the nail box. The operator releases the clutch controlling the rotation of the main shaft 13, and the link f rises, the clutch controlling the nut f be ing held out of operative position by the latch m The latch continues to hold the clutch until the nut m of the releasing device meets the ear m of the latch carrier, at which time the ascent of the carrier is arrested and the latch is immediately pulled away from the clutch, permitting it to clutch and restrain the rotation of the nut, and thereafter the nut, held positively during its further rising move- 7 partially driven nails from the nail box preparatory to the top-lift carrier turning and putting its top-lift into the space between the tread end of the heel and the nail box, at which time the top-lift is spanked upon the heads of the nails, as previously described. Just before the completion of the descent of the link f, the lower end of the carrier m meets a projection of the stand m and is arrested, while the link continues to descend, and the outer end of the clutch lever is put into position to be engaged by the latch, the latter having been turned somewhat upon its pivot on the carrier by the contact of the nut n with. the stop 01 so that the outer end of the clutch is practically carried below the point of the latch, the said latch thereafter by a slight movement about its pivot eifecte'd by the nut or collar n striking the under side of the stop n engaging the end of the clutch and turning the same in the direction to release the nut.

The nut, co-operating with the screw re- "fcrred to, constitutes what may be denominateda slip device, and the clutch referred to, in its co-operation with the nut, enables the latter to slip-on the screw or to move the screw in unison with it longitudinally,.at the desired times, as has been fully described.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
