To all whom it may concern:

Be it known that I, MA'rrnrAs BRooK, a citizen of the United States, residing at Boston, in the county of sulfolkand State of.

Letters Patent of the United States No.

1,018,477 for improvements in lasting ma- An important feature of this invention is found in the combination with a support for one end of a last of a support for the other end of the last which is bodily movable laterally relatively to the first support about a center located between the two supports.

In the illustrated embodiment of the invention the center of movement is located under the last which is to be supported and substantially at the intersection of the median lines of the forepart and the heel part of a crooked last. The center may be adjustable from and toward the relativelystationary end support. This embodiment of the invention is particularly useful in supporting shoes for the operation thereon of end lasting or other mechanisms which it is desirable should work in symmetrical or other predetermined relation to the median lines of the adjacent end portions of each last presented thereto. For example, it is important that a shoe shall be so supported relatively to the heel band of a heel lasting mechanism that the band shall act symmetrically and uniformly in clamping the upper materials adjacent to the two ends of the heel-stiffener firmly against the opposite sides of the last. Also that a welt shoe shall be so supported with relation to the position and the direction of operative movement of the toe lasting plates that said plates shall advance symmetrically relatively to the upper and shall press it uniformly over the edge of the last at the two sides of the shoe-and agalnst the channel lip or shoulder to which it is to' be secured.

, With these considerations in mind the in-' vention is herein embodied for illustrative purposes in a shoe support for a bed lasting machine having a rest for one end of the shoe located in the "median line of the machine and relatively-to which the lasting mechanism for the adjacent end of the last advances symmetrically, and a rest for the other end of the last which is mounted to move laterally toward either side of the machine in a curvilinear path into the median line of the end of the last which it is to support. In the machine shown a last pin constitutes one example of a heel rest and theheel embracing band constitutes another form of heel rest because it is a heel end face abutment. -As I am advised it is new by this invention to provide in a jack the combination with a forepart rest of a heel end face abutment which is supported for bodily lateral movement about a center located in front of said heel end face to adapt its position to that of the heel ends of right and left crooked lasts supported with their forteparts in similar relation to the forepart res Other features of this invention include devices, which may be adjustable, for limiting the lateral movement-of the shiftable member of the shoe support, or for looking or both limiting and then locking said member; and further may include means for effecting adjustment together of the devices which limit or look against movement toward opposite sides of the machine.

A further feature of this invention-is to be found in a novel arrangement and construction of a heel support which'comprises a holder in which a heel post carrying a last pin is mounted to have a limited lateral movement against springs which normally hold the post centered. This movement of the pin compensates for inaccuracies which crooked last that is being supported. For

further adaptation of the support to the' rest upon the finished surface of the shoe leather and thus prevents injury to the shoe which might otherwise occur.

These and othere features of this invention, including certain details of construction and combinations of parts, will more fully appear from the following descrip-' tion of the illustrated embodiment thereof and will be pointed out in the claims.

The expression crooked last is sometimes used herein for convenience in refering to lasts in which the median line of the fore part is oblique to the median line of the heel part.

Figure 1 is a side elevation of a lasting machine equipped with this invention; Fig. 2 is a plan view of the machine showing a left shoe on a crooked last and supported in position for operation of the toe and heel lasting mechanisms symmetrically'upon the respective ends of the shoe; Fig. 3 is a longitudinal vertical section of the machine; Fig. 4 is a detail showing provision for adthe center about WhlCh the heel support turns; Fig. 5 is a section on the line 55 of Fig. 3; Fig.6 is a front view of the toe rest; Fig. 7 is a horizontal section through the toe post; Fig. 8 is a detail view of the locking devices for the heel support as seen from the rear of the machine in The frame 2 of the illustrated machine supports the toe-lasting mechanism A and the heel-lasting mechamsm B between which are located the toe rest 4 and the heel support 6. The heel support and the heellasting mechanism are carried forlateral movement by 'a. plate 3 which is connected pivotally with the frame by a pin 5. This pivot pin is located under the last and at a point removed from both ends of the last and at, or approximately at, the point of intersection of-the median llnes ofthe" heel part and forepart of the last. If desired, a the pin '5 may be adjustable-as, for, ex-

--ample, by providing a slot in the frame, as

shownin Fig. 4. By this means the center about which the heel support is movable may be differently ositioned for lasts in which the point of Intersection of the median lines is located farther forward or backward in the last. In the movement about the pin 5 the plate 3 slides fre ely overthe frame, being supported by rolls 1' as shown 1n Figs. 1 and 2 which travel on a curved track 25, and the movement is limited by stops 7, as shown in Fig. 2. These stops are adjustably mounted equidistant from the middle line of the machine upon a right and left threaded screw 9. The screw is provided with a crank 0 by which it may be turned for adjusting the two stops together toward or from the middle of the machine. These stops serve to limit the lateral movement of the heel support and when one of them has been adjusted into the right position for a right last, for example, the other one will be correctly located also for the left last and for all lasts of the same style. The

heel support is provided with a locking device adapted to cooperate with either of the stops 7. I This device comprises a movable that the operator may grasp the lever and the post and by a single movement unfasten the latch block from the stop and then move the heel support laterally about the pivot 5.

In bearings in the frame 2 there is mounted the cam shaft 8, Fig. 3, to which is fixed a ratchet wheel 10 engaged by a pawl, not shown, mounted on a circularly movable pawl carrier 14 and connected by arod 15 with a treadle 16, shown in Fig. 1, as well known in lasting machines. Mounted upon the shaft is a cam 20 which engages a roll on a vertically movable slide 22, guided in the frame and forming a movable support of the toe rest. This rest includes a rod 24 provided with an adjustable screw 26 at its lower end which sets upon the top face of the slide 22. The rod extends through a guide'28 which is located in the median line of the machine and-is adjustable forwardly and backwardly by a stem 29 in the toe lasting head, and is grooved to receive a 'screw which limits its turning movement.

6. A second slide '34, carrying the pad of the toe rest is movable lengthwise of the machine in the slide 30 and is normally held in a central position by the springs 36, also shown in dotted lines. By this arrangement of the'toerest and its' actuating mechanism the toe pad, which is normally stationary as to horizontal position and does not partake of the lateral adjustment of the heel restabout the center 5, may accompany the last in any slight shifting movement of the shoe either lengthwise or transversely of the machine and is raised for lifting the last inthe jackin operation. The

heel support, together wit the heel-lasting mechanism, is movable lengthwise of the plate 3, as in the well known Ideal lasting ,machine, from a retracted position which able rod 87 that slides laterally with theheel support, over the head of a loose plunger 88 which is operated from a cam 89 on the cam shaft 8 to release the hook. This release takes place as a part of the unjacking operation after the shoe has been lasted and occurs simultaneously with the lowering of the toe rest supporting slide 22.

The heel rest is carried by a-slide 40, see Fig. 3, which is movable lengthwise of the machine in the plate 3 from which it obtains its movement laterally about the pivot 5 as does also the heel-lasting mechanism.

For effecting movement of the heel rest lon-' git-udinally of the-machine in the jacking operation the slide 40 is provided on its upper face with rack teeth, which are engage-d by a pinion 47 on a shaft 44 which has a hand Wheel 45. The hand wheel is provided on its inner face with ratchet teeth which are engaged by a spring-pressed pawl 46, as shown in Fig. 2, to holdithe parts in their adjusted position. A spring 48 acting against the slide presses the heel rest forwardly away from the heel-lasting mechanism when the pawl 46 vis released from the hand wheel. The heel post is provided in its lower end with an adjusting screw 50 which rests upon a plate 52 connected pivotallyto the slide 40 at 54 and having an inclined face which rests upon the end of a screw 55. This screw is freely movable endwise in the carriage of the heellasting mechanism and is adjustable in a nut 56, which is supported by a spring 58. The screw thus provides a yielding support for the plate 52 and by its engagement with the inclined face of the plate causes the plate to be lifted as the slide-40 and heel post are moved rearwardly to draw the last into the heel band of the heel-lasting mechanism. This arrangement provides for adjusting the heel post vertically according to the size of the last inasmuch as the extent of the backward movement of the post into the band will vary according to the dis 'tance between the pin holes and the rear end of the last, being less for a large last than for a small one. This engagement of the shoe with the band causes the post, as it is pulled .backwardly by the engagement of slide 40 with the lowerpart of the post, to

'rock or fulcrum about the upper portion 41 of its guidewa-y in the slide 40 so-that the lower portion of the post, which is toothed on its rear side as shown in Fig. 3, is forced into engagement with pawls 53, the guideway in the slide. being somewhat longer from front to back at its lower'portion' than is the corresponding dimensionof the post so that this movement of the postis permitted. The teeth are formed to hold the post against downward movement, but offer no obstacle toj'the upward movement of the post. When the post is tipped out of contact with the pawls it is free to move either upwardly or downwardly. A rod is'arranged below the plate 52 and connected to atreadle 62, shown in Fig. 1, for raising the heel post and the heel end of theshoe or positively upholding them during the lasting operation if desired. The heel post, which at its lower end fits closely the width of the hole in its holder 40, is reduced somewhatvin width at its upper end, as shown in the sectional view Fig. 5-to permit the post to tip'sidewise. Springs 64:-

hold the post normally in its central posi-- tion, but allows it to tip toward or against the walls of the holder which furnish rigid stops to limit its movement. The last pin 65, which enters the pin hole of the last is tapered to permit some movement of the last thereon and is connected to the post by a ball and socket join-t. This provision for the post to move laterally and for the pin to move independently upon the post enables the heel support to adapt its position to-the position and the inclination of thepin holein the .last. This'is an advantage because the pin holes in lasts are not. always accurately located, nor are they always drilled j at the same inclination to the face of the last, and, moreover, in some very crooked lasts the'pin hole is located on the left side of the median line of the heel part of a rightlast, as in Fig. 5, and on the right hand side of this median line of a left last. The jacking operation effected by the ma chine is produced by depressing the foot the cam 20 to raise the toe rest positively,

thus forcing the last firmly back into the heel band and clamping it rigidly in posi tion to be lasted. The cam shaft also carries a cam 70 which actuates during this jacking operation devices, not necessary here to consider, which are connected with the heel band for closing the band about the sides of the heel portion of the last to force the upper materials, including the heel stiffener, snugly into contact with the sides of the last.

In the use of the machine the workman selects the shoe to be lasted and, according as the shoe is for a right-Ora left foot, he may preliminarily shift the heel -lasting mechanism laterally about the ivot'5 into approximately the position required for that particular crooked last, and cause the latch 1.1 to interlock with the stud 7, Fig. 8. He then places the shoe upon the heel support and runs the heel-lasting mechanism forwardly into its operative position where it is held by the hook 35, the forward portion of the shoe resting at this time upon the toe support and being adjacent to the toe wipers. The position of the shoe in the machine is then observed and if it is not such that the median line of the forepart of the last coincides with themedian linevof the machine and the toe-lasting mechanism faces squarely toward the toe end of the last or toward the median line of the forepart of the last the lateral adjustment of the heel support mechanism is corrected to obtain these relative positions by using the crank 0 to turn the screw 9 and slide the plate 3 farther, or retract it as may be required to position a shoe. This movement is transmitted through the plate 3 to swing the heel post 6 around the center 5. The toe rest 4 slides laterally and turns with the shoe durin this adjustment .so that no abrasion o the upper leather is caused. Then by means of the hand wheel 45 the heel post is moved rearwardly and upwardly for drawing the heel portion of the last firmly into the rear portion of the heel band and raising the last to present the bottom face of the shoe in the plane of the heel wiper plates. In this movement of the last rearwardly the toe rest slides backwardly, Fig. 3. The operator then depresses the treadle 16 for causing the jacking mechanism to be operated. In this operation the toe rest is lifted by its cam 20 to tip the shoe backwardly toward and into the heel band and the heel band is closed through motion communicated from the cam to clamp the sides of the last. These jacking operations having been completed, the workman, by means of thehand levers 79 and 106, connected with the usual lasting devices, works the upper over the toe and heel ends of the last into position to be secured. Usually the foot treadle G2 is employed for raising the last upwardly against the heel lasting plate to compact the. overworked upper material against the innersole before it is fastened. \Vhcn the lasting has been completed the camshaft is again actuated by the treadle 16 and the cams turned into a position to let the toe rest descend toward its shoe receiving position and to unlock the hook 35, thus permitting the heel -post"- and other devices controlled by said hook to move rearwardly by the contraction of the spring 80 and allowing the heel band to open for unclamping the shoe. In proceeding to prepare for lasting another shoe if it is a shoe for the same foot as the one last operated upon and is the same style of last, no lateral adjustment of the heel-support will be required. If the last is for the same foot but of a somewhat different style, being more or less crooked, a slight lateral adjustment of the heel support will position the shoe with the median line of its forepart symmetrical with relation to the median line of the machine and to the toe-lasting mechanism. When a shoe for the other foot is to be lasted the operator frees the locking block 11 of the heellasting mechanism fromthe stop 7 by manipulating the lever 13 and by movement applied through the post 17 he shifts the median line of the machine and to the toelasting mechanism for these mechanisms to support and operate upon the right shoe of a pair of shoes, supposing that the previously treated shoe was for the left foot. If at any time after a shoe has been jacked it is found that the median line of the forepart does not bear such relation to the median line of the machine or to the direction of advance of the toe-lasting mechanism that the toe portion of the shoe is presented accurately to the toe wiper plates, or that because of an irregularity in the formation of the channel lip the upper requires to be forced over the last bottom farther on one side of the shoe than on the other side, then the heel support will be adjusted laterally as may be required to shift the last into the required position. In this adjustment the heel support serves as the point of contact through which movement is imparted to the last for turning the latter. This turning movement takes place in practice about a pivotal point at or near the toe of the last, the shoe being more or less confined between the toe wipers; It is to be observed that the pivotal point about which the heel support turns is not necessarily the point about which the'last turns. The heel band of the heel-lasting mechanism which is movable with theheel post about the pivot 5 serves, independently of its lasting function, as oneform of end face abutment for the last toprevent rearward dis placement of the last and, by its lateral curvilinear adjustment said abutment adapts its position to that of the heel end of a right or left crooked last.
