LASTlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 542,199, dated July 2, 1895.

Application filed July 27, 1891. Renewed October 18, 1894. Serial No. 526,320. (No model.)

To all whom it may concern.-

Be it known that I, DAVID LAKE, a citizen'of the United States, and a resident of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain Improvements in Lasting-Machines, of which the following is a Specification.

Myinvention is based on the improvements in lasting-machines made by WVhiffen, Lake 85 Lake, and for which application for Patent was filed in the Patent Office on October 14, 1889, Serial No. 326,932. The object of my invention is to simplify the construction of the machine and to make the several parts adjustable in series, so as to last shoes of different sizes and shapes. This object I attain in the following manner, reference being had to the accompanying drawings, in which Figure 1 is a plan view of my improved lastingmachine with the last in position. Fig. 2 is a transverse sectional view showing the different parts open to receive the'last and upper. Fig. 3 is a transverse sectional view showing the upper grasped by the nippers, the last forced into the upper, and the presSer-pad pressing at the sides. Fig. 4 is a transverse sectional View showing the nippers released and the presser-pads pressing the upper against the insole on the last. Fig. 5 is a side view of the machine with some of the parts removed. Fig. 6 is a longitudinal section of the upper part of the machine on the line 1 2, Fig. 1. Figs. 7 to 14 are views of the different lifting and pressing cams. Fig. 15 is a perspective view of the lifter-carrier for adjusting the height of the presser-pads. Fig. lb is a perspective view of the shifters for controlling the lateral movement of the presser-pads to adapt the machine to shoes of different styles. Figs. 17 and 18 are detached views of the presser-pads and carriers. Fig. 19 is a perspective view of the front presserpad-carrying lever, and Fig. 20 is a plan view of the last. v

Before describing the details of the invention I will give an outline illustration of the working of the machine.

The machine has indicator-marks in two places, one in connection with the resser-pad lifters and the other in connection with the presser-pad shifters. The lifters regulate the pads to accommodate a last for different-sized shoes, and the shifters are regulated to accommodate lasts of different shapes, but the operating mechanism remains the same for all styles and shapes of shoes.

The presser-pads themselves are numbered and lettered for the different sizes and shapes of shoes,'so that if a N0. 4 shoe is to be lasted, style D, the lifter is moved to the four index and the shifter to the 4 index, and a set of 4-D pads are placed in their respective positions around the last-support. The last is now placed on the supports and the upperplaced over the last, the edge of the upper passing into the open jaws of the nippers around the last. The machine is then put in motion, the grippers first closing upon the edges of the upper, merely holding the upper by friction, and the last is forced up into the upper by the movable last-support, moving the upper in the jaws until a certain point near the edge of the upper is reached, when the jaws take a positive hold upon the upper, the last-support moving to its final position, at which point the upper is tightly drawn over the last. The pressenpads then bear upon the sides of the upper at the lower edge of the last, the nippers are released from the upper, and the presser-pads turned under the upper, so as to force it against the under side of the last or insole, it being understood that the insole and inner edge of the upper are coated with cement prior to the adjustment of the last in the machine, as fully set forth and claimed in an application filed by me on the 26th day of September, 1894, Serial No. 524,137. The stop-rods which press uponthe upper portion of the last are then moved to allow the shoe to be withdrawn from the ma- 9o chine, after which the operation can be repeated on another last and upper.

' Referring to the drawings, A is the base of the machine, mounted on suitable supports or legs a, and A is the table, mounted on legs 5 or standards 0., secured to the base A, as

clearly shown in Fig. 5. It will be noticed that in the present instance all the prime movers are slides adapted to slide vertically on ways on the frame. These slides are moved 10o by cams B 13 13 B on the cam-shaft B. Both faces of the cams have cam-grooves cut in them, as clearly shown in Figs. 7 to 14.

D is the pad-plate, by which the pads are moved toward and from the last. This plate is connected to levers D by connecting-rods D and links D as clearly shown in Fig. 2. Each lever D" has a pin or roller d, one eutering the cam-slot b, Fig. 7, and the other entering the cam-slot 0 Fig. 14. These two cam-slots are cut alike, so as to give the same vertical motion to the plate D.

E is the gripper-plate, on which are mounted the series of grippers, to'which are connected the series of presser-pad blocks, the vertical reciprocating motion of this plate not only lifting the grippers, but also turning the presserpads on the last. This plate is connected to levers E by rods E and links E A pin or roller e on each lever enters the cam slot c and cam-slot bflFigs. S and 13.

F is the jaw-plate, to which are connected the jaws of the nippers, the vertical motion of the plate opening and closing the jaws. This plate is connected by links F and. rods F to levers F pins or rollers f on the levers F F entering the cam-slots c and 0 Figs. 10 and 12.

G G are the last-supporting rods, which are adapted to move vertically in suitable bearings, which are connected by links G2 to levers G rollers or pins 9 on the levers G G entering the cam-slots b and b Figs. 9 and 11. one another, if necessary, so as to give the toe portion of the last a different movement from the heel portion.

The several levers E F and G are attached to brackets A secured to the base A of the machine.

A are vertical guide-rods, on which the plates D, E, and F slide, as clearly shown in Fig. 5.

H H are hollowspindles, each carrying at its upper end a fixed head h, to which is pivoted a jaw 7L, and pivoted to this head or to the jaw h is a jaw h having a smooth surface and a. serrated or roughened surface.

Around the heel portion of the upper I prefer to place the jaw 71.2 on the fixed jaw of the head 72, while around the toe portion I prefer to place the jaw ]L2 on the movable jaw h. A sleeve 2' acts upon the jaw it, this sleeve 2' being carried by a rod 2', (shown by dotted linesin Fig.- 2,) which is connected to a rod I, passing freely through the gripper-plate E and through the plate F. On each jaw-rod I are springs 1, the spring 2 being confined between a nut t and the plate F and the spring 71 being confined between the plate F and a nut 2' one spring being confined on one side of the plate F and the other spring being on the opposite side of said plate. These springs can be adjusted by their respective nuts, so that more or less pressure can be applied to the jaws; but in case of accident the ment.

These two cams can be cutout of line with springs will yield sumciently to prevent any breakage of the jaws.

The spindles H H are carried by the gripper-plate E and have pinsjj, which are adapted to bearings e on the plates E to allow the spindles to have free movement toward and from the last.

.T J are collars loose on the spindle ll, and between them and the pins j are springs J, which tend to keep the collars up againstthe bearings J carried by projections J on the plate E. The under sides of these bearings J are slightly V-shaped on the line of the pivotpins j, and the upper sides of the collars J are also V-shaped to correspond to the cut of the bearings J so that, while the grippers can have free movement laterally toward and from the last, they are always returned. to the normal position, clearly shown in Fig. 2. The slots inthe cams which operate these two plates E and F are so timed that the plate F moves first to close the jaws, after which the plate F returns to open the jaws and the plates E and F are lowered, so that the jaws will clear the pressers.

No special arrangement is necessary to adjust the series of jaws for different sizes and shapes of shoes, as sufficient play is allowed for the purpose.

I will now describethe presser-pad arrange- The presser-pads m are carried by blocks M, to which they are secured, as clearly shown in Figs. 17 and 18. These presser-pads are preferably made of rubber and are backed with a metallic plate m, having a grooved lug m through which passes a locking pin or bolt 777.. Hence by operating this bolt the pad can be readily removed from the block M- and another pad substituted therefor. Passing through the block M is a pivot-pin n, the two wings n of the block passing on each side of a curved arm N of a lever N. This curved arm has a curved slot 7L2, through which the pin n passes and by which the block is guided. The lever N is pivoted at p to a vertically-adjustable post P, the arm N of the lever being connected by a ball-joint to a post Q by a connecting-rod R, made in two parts 0' r, and between these two parts is a spring r adapted to the spindle r on the part r. The lower portion of the part 7' forms a casing for the spring, as clearly shown in Fig. 2, so that there will be a yielding pressure on the pad when forced against the upper.

S S are two slides situated on each side of the machine and adapted to slide toward or from each other on the pad-plate D, and on these slides are bearings S, in which are inclined slots .9.

The posts Q are adjustable in the pad-plate D and have pins q g, which are adapted to the inclined slots sin the bearings S, and the slides S have lugs s, in which are screwthreaded orifices, to which is adapted a screwrod S having a hand-wheel 5 by which it is turned, so that by turning this screw-rod as clearly shown in Fig. 2.

S in one direction the slides S are moved apart and the pivot-points ofthe connectingrods R are raised, consequently throwing the pads nearer to the center of the machine, while if a reverse motion is imparted to the screw-rod S the slides are drawn together and the pads are moved away from the center of the machine, owing to the fact that the pivots of the rods R are lowered. Hence by this mechanism the pads are adjusted to accommodate diiferent shapes of shoes.

The posts P, carrying the pivot-pins of the levers N, are adapted to sockets P, which have their bearings in the table A. Each post is adjustable vertically in its socket by means of a screw-plug 19', between which and the end of the post is a spring 13 surrounding a rod, 19 screwed into the shank of the post, Thus each post P can be adjusted separately to make up for irregularities and for wear. On each socket is a pin t, and each pin is adapted to an inclined slot t in a yoke-frame T, Fig. 15, which I term the lifter. To the yoke .proper T are connected the armsT T in which are the inclined slots 6', these arms being secured to the yoke proper by pins or by bolts F. A screw-stem U, mounted in bearings U on the table A, is adapted to a threaded opening i in the lifter T, and this screw-stem is provided with a handle U on turning which the lifter can be moved on the table, and owing to the inclined ways if, in which the pins 25 of the sockets P rest, the sockets, posts, levers,

and presse'r-pads are raised and lowered and the pads are thus adjusted to accommodate lasts of different sizes.

The lifter-frame can be constructed in a different manner from that herein shown without departing from my invention; but for convenience I construct it as described above.

Connected to the pin n of each block M, or to any convenient point on the block, is a rod M, connected to a vertical rod M which passes through ways in the table A and through ways in the gripper-plate E. Springs u u are mounted on this rod M above. and below the plate E, and nuts u and a are adapted to the threaded portions of the rod, so that the tension of the springs can be regulated and the rod M adjusted vertically to accommodate the block M. This rod M turns the block M from the position shown in Fig. 3 to the position shown in Fig. 4, and the of the lever by which it is carried, so that the gripper will not be in the way of the presserpads when acting.

On thetoe presser-lever shown in Fig. 1 are chine with a pair of hand-nippers, which he uses in drawing the toe of the upper over the last while the nippersof the machine are drawing the remainder of the upper overthe last, as I have found thata much more satisfactory result is obtained by having the attendant draw down the upper on each side of the toe by hand-nippers, while it gives the attendant sufficient to do to keep him at the machine, and thus prevent had work by neglect of the operator.

The cam-shaft B is driven from a drivingshaft 0 through the medium of a worm Oand a worm-wheel C The worm C is loose on the shaft 0, but can be clutched thereto by a clutch G a clutch-lever C being in engagement with the clutch and connected by a rod 0 to a treadle C (Shown in Fig. 5.)

On a standard A is an arm to, pivoted at to, which is for the purpose of guiding the operator in placing a last on the machine, as it will be understood that the heel of the last must be set in a certain position 011 the lastsupport, and by having the indicator-arm w the last X, Fig. 20, can be marked, as shown at 00, when first applied to the machine, so that it can always be set in the same position in respect to the arm w, and the abutment-rods W W can. be adjusted accordingly, the abutment-rod W fitting the ordinary orifice X in the heel portion of the last, Fig. 20. The abutment-rod W has a shoe 00 which rests upon the toe portion of the last, as clearly shown in Fig. 6. Each rod is adapted to bearings 2, carried by arms Z, projecting from the standard A. The bearings are adapted to slide on the arms Z Z, and adjusting-screws z are mounted in hearings on the arms and adapted to nuts on the bearing 2, so that on turning these screws the rods can be moved toward or from each other, and thereby adjusted for-lasts of different lengths. On each bearing zis a rod 2 on which slides a sleeve .2 and between the sleeve and a nut .2 is a spring 2 Projecting from the sleeve 2 is an arm 2, and through the arms on each sleeve pass the abutment-rods, and on each abutment-rod is a fixed collar 10 so that it will be seen, on referring to Fig. 6, that the abutmentrods W W are forced upon the last by the spring 2 but will yield for any independent vertical motion of the last. Each sleeve Z3 is provided with a handle w Fig. 1, so that by simply turning this handle the arm 2 can be thrown out clear of the rods to allow for the free adjustment of the abutment-rods.
