vSPECIFICATION forming part, o f Letters Patent No. 653,042, dated July ,3, 1900..

- Application tied october 5,1899. serai No. 732,657. ou man.)

Be it known that we, WILLIAM SELLERS and JOHN SELLERsBANoRoFT, citizens of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Shoe-Lasting Machines, of which the following is a full, clear, and exact description, reference being had to the'accompanying drawings, which form a part of this specication. y

Our invention relates to that class of shoemachines which stretch ythe upper over the last and secure it to the insole by glue or'cement-such, for example, as that' described and claimed in the Letters Patent ofA the United States issued to William Sellers, John Sellers Bancroft, and Mauritz O. Indahl, assignors to William Sellers it Oompany,:In corporated, April 10, 1900, No. 647,037; and the object of this invention is to improve the machine forming the subject-matter of said patent by perfecting the structure and operation of the crimping devices, the pincers or nippers, and the rocking clamps and folders which operate upon and against the side and under surface of the last at the shank;

To these ends our invention consists in providing means whereby the bars that slide underneath the last and crimp the leather of the heel and toe at different points preparatory to the operation of the bars for folding the leather underneath the last at the heel and toe are caused to be automatically retracted in proper sequence to permit the folders to operate.

It further consists in the provision of an equalizng device connecting the sets of rocking clamps and folders on each side, whereby no pressure will be exerted against the last by the folders first coming in contact therewith until the corresponding folders on the opposite side are brought against the last and whereby in the subsequent operation of the machine the clamps on opposite sides will be caused to press with equal force against the last.

It further consists in a special construction of the pincel-s or nippers that act upon the View of the machine.

leather at the toe whereby the jaws of the nippers are caused to first clamp the leather and then shift their position preparatory to being moved down to stretch the leather over the last, in improved automatic mechanism for imparting tothe nippers the desired operation, and in the provision of means whereby the jaws of the nippers'may, if desired,

kloe closed and their position shifted by manual 'means preparatory to the automatic operation of the machine. I

It further consists in certain details of construction and combination of elements to be tial respect from th'e machine specifically described in the Letters Patent No. 647 ,037, hereinbefore referred to. We shall then describe more particularly the structure and operation of the improvements forming the subject-matter of this application.

In the drawings, Figure 1 is a partial end Fig. 2 is a section on line 2 2 of Fig. l. Fig. 3 is a plan view of the machine. Fig. at is a partial section showing the rocking clamps and folders and equalizing devices. Fig. 5 is a detail section through one ofthe crimpers and its actuating mechanism. Figs. 6 and 7 are detail views of the pincers. Figs. 8 and 9 are diagrams showing the nippers in different positions.

l is the frame of the machine.

l is the main bed-plate, and lb the supplementary bed-plate, supported by the main bedplate on standards or posts.

2 indicates the supports arranged to receive the last 3. The last is clamped in position upon these supports by last-clamping mechanism, not herein shown, as the same forms no part of our invention. The insole is secured 'upon the bottom of the last by means of temporary nails or pegs. The upper is drawn down over the last, the depending edges having been previously prepared with glue to adhere quickly to the insole, which is similarly prepared to insure adhesion when in the operation of the machine the upper is folded inwardly against it.

4 indicates the nippers, three in number, which set upon the leather at the toe, and 5 the nippers, six in number, which act upon the leather at the shank. The nippcrs 5 are the samein construction as those described in the said Patent No. 647,037 and extend down through and engage the table A and are connected with the tables B and B', which are bolted together to act as one. By means of the downward movement of the tables B and B the jaws of the nippersare closed upon the depending edge of the upper, and by a further movement of said tables, together with a simultaneous movementof table A, the nippe'rs are drawn bodily down, stretching the upper down closely over the instep. After the tables remain stationary the required length of time that it is desired to hold the upper stretched tables B and B move up to relieve the grip of the pincers, and then tables A, B, and B' move down together to carry 'the pincers out of the road of the folders that subsequentlycome into action. The nippers 4 operate, generally speaking, in the same way to pull the upper down closely over the toe. Their construction, actuating mechanism, and operation will be hereinafter more fully described. To secure the 4leather thus stretched against retraction upon the last at the heel and toe, we provide the clamps or clamp-bars 6, there being nine at the toe and seven at the heel, and the binders, crimpers, or crimping-bars 7,which are eight in number, four at the toe and four at the heel, and arranged alternately with respect to the clam ps. The clamps are caused to press against that part of the upper lying against the last immediately above the insole, while the crimpers, which are pointed bars, are at the same time caused to move inward underneath the last, bending certain portions of the depending leather inward preparatory to the folding operation, and which, in addition to coperating with the clamps to prevent retraction of the upper, prevent the irregular overlapping of the leather at the sharp curves of the insole at the heel and toe by the subsequent action of the folding-bars. The clamps are secured to the rocking carriages 8, which are pivoted to the supplementary bed-plates and connected, by means of spring-pressed rods 9, with the lower table C and are thrown into action by the upward movement of the lower table. The crimping-bars slide in guides on the frames 29, and their construction, actuating mechanism, and operation will be hereinafter more fully described.

To bend the edges of the upper inwardly against the insole at the heel and toe, a series of folding-bars 11 are provided, ten in number, five at the heel and five at the toe. These folders slide in guides on the five end carriages 8 at the heel and toe, respectively, and each is actuated by means of a bell-crank (not shown) below Ithe bed-plate of the machine. The folders are caused to move in after the clamps have acted, and the clamps remain stationary during the operation of the folders, while the crimpcrs are caused to be retracted to permit the folders to move in without interference by mechanism to be hereinafter described.

The mechanism for acting upon the instep is as follows: ln place of the clamps G at the heel and toe the rocking clamps or pads 13 are provided, six in number, three at each side of the machine. Each of these pads is secured to the ends of two parallel horizontal levers 14, pivoted upon two parallel upright levers 15, pivoted to the rocking carriage 16. The carriages are pivoted to the supplementary bed-plate and are connected to springpressed rods 17, connected with the lower table C. The pads 13 are thrown toward and against the upper by the upward movement of thc lower table, and then by the subsequent folding in of the parallel-lever mechanism the pads move down and draw the leather tightly about the instep and downward around the curve thereof.

In place of the sliding folders 11 at the heel and toe we provide the rocking folders orpads 18, which are twelve in number, six on each side. Four of these pads are carried by the four carriages 8 at the junction of the toe and shank, two of them are carried by the two carriages 8 at the junction of the heel and shank, while the remaining six are carried by the carriages l 16, which also carry the rocking clamps. Each pad is carried by its carriage in the following manner: Upon the carriage are pivoted a spring-actuated bellcrank 19 and a lever 20, the bell-crank and lever being connected by alink 2l. A springpressed arm 22 carries at its forward end the pad, which is connected by a link 23 with the lever 20. To the arm 22 is pivoted a link 24, which is slidably connected to the carriage. The carriages are connected, as before de- IOO IIO

scribed, with the lower table C, which by its upward movement brings the pads 18 adjacent to the bottom of the last. Spring-pressed rods 25 connect the bell-cranks 19 with the upper table A, which by the downward movement thereof draws the bell-cranks, which, through the link and lever connections described, impart a rolling lnotion to the pads 18, effecting a pressure and adhesion of the edge of the upper against the insole.

The tables A, B, B', and C are actuated by means of cams underneath the bed-plate of the machine; but as these and their connections with the tables are fully described in the Patent No. 67,037 it will be unnecessary to here illustrate or describe them.

We will now describe more particularly the mechanisms which embody the invention forming the subject matterof this application.

The machine herein described is designed to last both right and left shoes. The mechanisms on each side of the machine that are provided to effect the lasting operation are precisely the same. inasmuch as the inside of the shank of a shoe differs in contour from the outside of the shank, the inside of the shank being also hollowed out more than the outside, :it will necessarily happen in the operation of the machine that the clamps and folders on one side will contact with the upper on the last before the clamps and folders on the other side. In the absence of auxiliary mechanism the clamps and folders immediately after engaging the upper would begin to exerta progressively-increasing pressure, the result of which would be that first there wouldbe lateral pressure against only one side of the shank and subsequently an .unequal pressure on opposite sides. This would eect an unequal stretching of the upper on opposite sides, and the lasting would therefore not be properly accomplished. We have provided mechanism whereby after the clamps and folders on one side are brought int-0 contact with the last they will be prevented from exerting any substantial pressure thereupon until the clamps and folders on the opposite side are brought into contact with the last, said mechanism operating as well to shorten the time necessary to bring the later-acting clamps and folders into contact. This mechanism is as follows: On each carriage 16 and on each of the four carriages 8 contiguous to the carriages 16 at the toe and on each of the two carriages 8 contiguous to the carriages 16 at the heel is a depending link 26, pivoted to a lug 27 on the supplementary bed-plate, this link constituting the only means for supporting the carriage on the supplementary bedplate. The links 26 of immediately-opposite carriages are connected together by means of the equalizing-bar 28, which is slotted at its ends to engage pins on the links 26. It will readily be seen that when the clamping-pad and foldingpad of any one carriage are brought into contact with the last by the rocking of the carriage on its pivotal connection with link 26 any further upward movement of the spring-pressed rod will draw the lower end of the carriage and the upper end of the link 26 outwardly, moving the equalizing-bar laterally and moving also the immediately-opposite carriage inwardly on the pivot of its link, this continuing until by the combined lateral movement of the equalizing-bar and the upward movement of its spring-pressed actuating-rod the immediately-opposite carriage is rocked to the extent necessary to bri-ng its clamps and folders against the upper. It will readily be seen that not until then do the clamps and folders first brought in contact with the upper exert any substantial pressure thereupon and that in the subsequent operation the equalizing-bars insure an equal and opposite pressure being exerted by immediately opposite clamps and folders carried by the specified carriages.

It is necessary, as before stated, to withdraw the crimping-bars preparatory to actu- 'pivotal su pport.

.block 49 are the rods 53 and 54.

l'ating the five folders at the toe and the five 32, which extends down through an orifice in the lower table C, the operating pressure being applied through the spring 33 to cushion its action.y The upward movement of the rod 32 tilts the bell-crank and moves the crimping-bar inward, as shown and described in said PatentNo. 647,037. To retract the crimpers, we provide the following mechanism: 34 is a bell-crank pivoted to the frame 29, one arm of which is pivoted to a rod 35,which extends down through the upper table A. The other arm of the bell-'crank 34 engages the end of lever 36, intermediately pivoted on the bell-crank 3l. The opposite end of lever 36 engages a fixed stop or abutment 37 on the frame 29. When in the operation of the machine the. upper table has moved down to a distance suflicient to engage the washer on the lower end of rod 35, the rod 35 is depressed, rocking the bell-crank 34 and moving out the lower end of lever 36. As theupper end of lever 36 is prevented from moving inwardly by its engagement with the frame 29, the upper arm of bell-crank 31 is swung out to withdraw the crimper, the spring 33 yielding to permit the rod 32 to be depressed.

We shall now describe the construction of IOO the toe-nippers 4 and their actuating mech- Y per ends of the side pieces, is the member 40,l

having the jaw 4l and a cam-slot 42. In the slot 42 is a block or roller 47a, said block or roller being substantially the width of slot 42.

Pivoted on the rod 43 is the bifurcated mem- Aber 44, embracing the member 40, having the jaw 45 and the cam-slots 46, said slots being at an angle with slot 42. Extending through slots 42 and 46 and block 47a is the pin 47,

connect-ing the upper ends of the side pieces 48, the lower ends of which are secured to a block 49, slidable on the side pieces 39. The pin 47 is of size sufficient to substantiallyfill the slots 46, forming blocks or rollers in said slots 46.

50 is a block between the side pieces 39, and 5l a dog-sprin g connected with the block 50 and adapted to engage the inset 51L on the member 40 to limit the extent of outward and .upward movement of the member 40 ou its Secured to the block 38 is a l tuberrr 52. Projecting downwardly fromthe extends through one side of the block 38. The

' The rod 54,

IIO

rod 53 extends through the block 3S and tube 52, as well as through upper table A and hori- Zontal plates 55 and 56, and has a loose washer 57, which normally rests underneath plate 55, and a tight washer 58, which normally rests above the plate 5G.

59 is a block which rests upon the upper table A and through which extends the lower ends of tube 52 and rod 54.

60 is a nut on the lower extremity of tube 52 and abutting against the under surface of block 59.

G1 is a spring interposed between blocks 38 and 59 and surrounding the tube 52.

62 is a spring interposed between blocks 49 and 59 and surrounding the rod 54.

G3 is a spring interposed between washers 57 and 5S and surrounding the rod 53. The plates 55 and 56 are secured together to act as one and may be made of a single casting.

64 is a bolt extending through the central table B and plate 55. Surrounding the bolt i is a spring 65.

GG is a foot-treadle pivoted 011 the frame of the machine.

G7 is a rod connecting the foot-treadle with the bell-crank 68, pivoted on the frame of the machine, one arm beingconnected to the rod G7 and also to the rod 67, the other end of which is connected to the plate 56;

69 is a spring-pressed locking-lever having a detent 70. When the treadle is depressed to operate the toe-pincers, as will be hereinafter described, the bell-crank 68 engages and depresses the lever G9 until it passes beyond detent 70, whereupon lever 69 springs back into its normal position and locks the bellcrank from returning after the pressure upon the foot-treadle is removed.

When the treadle is depressed, the first operation is to draw upon the block 49 against the action of the comparatively-light spring G2, thereby swinging the nipper-jaw members and their directly-actuating parts from the position shown in Fig. 6 successively into the positionsjshown in Figs. 8 and 9. The same movelnent of the treadle necessarily compresses spring G5. Further movement of the treadle through the medium of spring 63 draws down upon the nippers bodily, compressing spring 6l and necessarily further compressing spring 65.

When the machine starts, the table B will first move downward until it is opposite the plate 56, permitting the spring 65 to expand. Before table B has reached this position the upper table A is caused to move downward, the spring 61 by the expansion forcing the block 59 to follow up the table A. The tables then move down together. Further downward movement of table B draws down plates 55 and 5G. The rod 53 is further depressed, drawing down the nippers still farther until the upper is stretched tightly over the last. Further downward movement of table A "permits the spring 61 to expand to its fullest extent. After the leather is stretched as tightly .as possible any further movement of table will merely compress spring 63. Both tables then remain stationary for an instant until the clamps have reached their limit of movement. Table B is then caused to move upwardly, permitting the spring 63 to expand to its full extent. Further upward movement of table B carries up the rod 53 and block 49, permitting spring G2 to expand and opening the jaws of the nippers. After the table B has reached its lowermost position and before it has moved in its upward movement to a point opposite the plate 56 the foot-treadle is released by the following mechanism: 71 is a projecting cam fastened to one of the cams 72 for operating one of the tables. This cam is in alinement with the locking-lever 69 and at the proper time engages locking-lever 69, unlocking bell-crank G8 and disengaging the foot-treadle and holding it disengaged until the rod 53 is moved up, as before described. After the nippers are released both tables move down together, carrying the nippers out of the road to permit the folders to be operated.

Having now fully described our invention, what we claim, and desire to protect by Letters Patent, is-
