SPECIFICATION formi-ngpart of Letters Patent No. 60 1 ,934, dated April 5, 18 98.

Applicationfiled April 14, 1896.

To all whom it may concern;

Be it known that I, 'MATTHIAS BROOK, of

Boston, county of Suffolk, State of-,- Massal chusetts, have invented an Improvement in Lasting-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts. v

In United States Letters Patent No; 548, 86 2,

granted to me under date of October 29,1895,

I have shown and described alasti'ng-machine wherein thewipers are made to open and close to wipe the upper .over and upon the inner sole and are also connected with a cross-bar which is manually movable to vary the lateral position or adjustment of the wipers to adapt the same to last ends of difierent inclinations or swing-such, for instance,as lasts either rights or lefts.

In this my present invention I have provided one form of vmeans'whereby the wipers or lasting devicesand the last are automatically and relatively adjustable to adapt said lasting devices or wipers to last ends having, different inclinationsthat is, a difference in swingwhether the lasts be rights or lefts.

Myinvention further comprehends means automatically and means manually foreffecting the relative adjustment of the said end Wipers and last to meet the varying swing, of a last, whether a right or a left, the said antomatic or the said manual means to be'employed by and at the will of the operator, according as automatic or manual means is desired.

Figure 1, in side elevation, represents the I head of a lasting-machine embodying my invention with the toe portion of a boot o'r shoe to be lasted shownin operative position. Fig. 2 is a front elevation of the apparatus shown in Fig. l with the boot or shoe omitted. Fig. 3 is a top or plan view of the apparatus shown in Figs. 1 and 2, showing also a boot or shoe .2

in position to be lasted. Fig. 4 is a longitudinal sectional View of the operative 'parts-of the head, taken on the line a: m, Fig. 3; and

Fig. 5 is an under side view of the cap for thetipping plate, with the side-wiper plates,

Serial No. 587,488. (No model.)

l their carriers, and the longitudinally-movable l slide-bar upon which they'are mounted.

Referring to the drawings, Figs.- 1 to 4, incl'usive, I have herein shown a tipping-plate holder A, having upturned ends a a to form bearings for journals b'b, respectively, of a tipping plate B, whereby the latter is adapted torock or tip laterally,suitable springs S (see Figs. 1 and 2) preventing undue movement of 3 the tipping plate upon its journals.

The tipping-plate holder A is mounted on i trunnions a extended through longitudinal slots c in the upturned part of the base 0, pivoted at C, Fig. 1, to a carriage D, which is adapted to slide longitudinally on the frame, said base 0 being freely rotatable about its said pivot O to-enable said base and the parts 5 carried thereby to freely adapt themselves to the inclination of the end of the last, as will be hereinafter described. The rear end of the carriage (see Figs. 1 and 3) is herein shown as provided with a rackibar'd tobe engaged at times by a suitablyshaped tooth 'd on a lever d pivoted to an jeajr a on the tipping-plate holder, whereby j the head of the machine may, when desired, be manually swung laterally about the pivot '0 and, if necessary, held in adjusted position on the carriage. The pivotal point of the head is shown in alinement with the center of the end of the last, and by the lateral adjustment of the head the side-wiper plates or wipers (to be described) are adjusted to the varying inclinations of the sides of the last for example, the last in a right or a left boot or shoe. I

- The base G is shown provided with a rearwardly-eXtended-and upturned horn C ,Fig.1, slotted at O to receive a stud of on the tipping-plate holder, and by means of an adj ust ing-screw a, connected by a ball-and-socket joint to one end of the horn and extended t through a threaded opening in theear a the tipping-plate holder A may be tipped upon its trunnions a to vary the inclination of the tipping plate from front to rear.

A toe-rest e of any suitable construction isherein shown as mounted upon a slidebar 1 c, Fig. 2, longitudinally movable in a guideway D, forming a part of the carriage and vertically adjustable by means of a cam D on a cam-lever D adapted to rock on a suitable stud by means of a hand-lever D all as in my other application hereinbefore referred to.

The tipping plate B has a raised portion 12 thereon to form a support for an actuatingcam F, provided on its under side or face with a cam-groove f and in its upper face with two cam-groovesf'f (see Figs. 3 and 4,) for a purpose to be described, the said cam being mounted on a suitable stud F, as clearly shown in Fig. 4c.

The tipping plate has adj ustably connected thereto a bracket g, in which is mounted an elbow-lever g, pivotally connectd at g to a toe-wiper holder 9 the other end of the lever being connected by a knuckle-joint g to a slide-plate 9 adapted to slide in a recess in the tippingplate B and provided with a suitable roller or other stud g to enter the camgroove f on the actuating-cam.

' The toe-wiper holder isvertically socketed to receive therein the shank 9 Fig. 1, of an end-wi per or clasp carrier, shown as a grooved plate g upon the inner or concaved face of which is secured a pad of leather or other suitable material, which constitutes one form of wiper or clasp to wipe the upper about the end of the last as the said Wiper or clasp is elevated by the rocking motion of the elbowlever g, the latter being actuated by a partial rotation of the cam F.

The end wiper or clasp may be free to swing laterally upon its shank g to accommodate itself toa right or a left boot or shoe, its shank g being shown as circumferentially grooved, asat g to receive a pin g", held in the socket, and which restrains said shank against endwise movement without interfering with the rotation thereof, said shank and its socket be- ,able bolts or screws, as 10, Fig. 3.

ing, however, provided with holes 9 into or through which said pin may be inserted to restrain said shank and its wiper against rotative movement, and thereby lock the same rigidly to the base and parts carried thereby for automatic adjustment, as will be hereinafter described.

An abutment h, to position the toe of the boot or shoe when placed upon toe-rest e, forms a part of an ab utment-plate h, adapted to slide longitudinally in a wiper-carrier support 7c, shown as a slide-bar movable longitudinally in the cap G, secured to the tipping plate above the actuating-cam by suit- A roller or other stud 71.2 on the under side of the abutment-plate enters the cam-groove f to be reciprocated thereby, the shape of the cam-grooves f and f being such that the abutment h is Withdrawn from the toe of the boot or shoe as the toe-wi per g is elevated.

The cap G is recessed upon its under side,

as stated, to form a guide for the slide-bar it, having a roller or other stud It to enter the cam-groove f and longitudinally slotted at k to receive a lug 72. on the abutment, for a purpose to be described.

In the construction herein shown, referring to Figs. 4 and 5, wiper-carriers m are pivoted at m to the under side of the slide-bar k, which herein constitutes one form of wiperactuator, said carrier being rocked or swung laterally by means of cam-plates at, secured to the wiper-carriers in suitable manner, as by a screw-and-dowel connection at n Fig. 5, the cam-plates extending at opposite sides of and above the slide-bar 7c and having therein slots 02 to be entered by fixed pins or studs 25 on the under-side of the cap G, whereby as the slide-bar 7c is moved forward the wipercarriers m will be moved forward and also plates being slotted at o concentrically to the said center to receive therein suitable adj usting-screws 0 on the carriers, whereby the plates may be adjusted upon their carriers independently one of the other to adapt them to the particular shape of the boot or shoe which is to be lasted. 7

The inclination of the sides of the boot or shoe at or adjacent the toe or heelz'. e., the swingvaries according to whether the shoe is a right or a left shoe and also according to the particular style of last, and to adapt the apparatus herein described to act upon either a right or a left boot or shoe or 011 rights or lefts of different styles it is necessary to laterally adjust the wiper-carriers and the said'wipers or Wiper-plates and the last relatively preferably about the center of movement m which latter is located in a line drawn along the bottom of the last from the center of the toe to the center of the heel thereof, and in this instance of my invention such adjustment is provided for by swinging the entire head of the machine about the pivot G of the 'base 0. By means of this lateral adjustment of the wiper-plates I am enabled to cause the latter to approach the sides of the last uniformly throughout their lengths and to wipe the upper over the last equally, inasmuch as the leading edges of the side-wiper plates can be brought up to the upper to act upon it simultaneously at each side of the toe.

It is obvious that the mechanism shown and described, without. substantial change and without invention, may be employed 'at the heel end of a last tolast the material thereat and likewise be adjustable thereat to meet differences in swing, for with rights and lefts the heel end of. the last varies proportionally as the toe end, and since substantially the same mechanism hereinbefore described is all that would be necessary to' accomplish the lasting and adjustment at the heel I have not shown the same.

As in my other application hereinbefore IZC.

referred to I have provided a tack or nail puller claw r to engage a tack or nail 50, (see Fig. 3,) driven into the upper at the under side of the center of the toe, said claw being formed on the end of a rocker-arm r, pivoted at r on the cap G, said arm being rockedon its pivot by means of a dog 1*, engaged by the lug h on the abutment-plate h when the, latter is moved rearwardly to withdraw the abutment, a pin r on the dog engaging a suitable ear r on the arm r.

To hold the tack or nail puller in raised position when withdrawn, as described, I have provided a spring-catch s on the cap to engage the foot r of the arm 4".

To prevent the inner sole from being moved rearwardly by the wiper-plates when wiping the upper thereover, I have provided a downhold if, adjustably mounted in a hub 25 on a rocking arm i pivoted at r and acted upon bya spring 8 to normally lift it, the arm having on its under side a locking-ear t to engage a shoulder 7 5 on the cap G and retain the downhold in place against the action of the spring. The arm is slotted at its pivotal point at 15 to permit longitudinal movement thereof when a lug t on the arm t is engaged by the cam-plates n in their forward movement to thus withdraw the projection i from the shoulder 75, the action of the spring 8 then lifting the downhold into inoperative position. A rest t on the cap is located in the path of movement of and acts as a limiting-stop for the upturned end i of the arm 25 when moved into inoperative position by the spring.

The actuating-cam F is partially rotated in 7 one or the other direction by .means of a suitable handle F movement thereof in the direction of the arrow 100,,Fig. 3, acting by or through the several cam-grooves f f f and the intermediate connections to withdraw the abutment h and move the toe-wiper or'clasp g to wipe the toe of the upper about the last and also to actuate the tack or nail holder, while the wiper-plates or wipers are moved. forward and closed to wipe the upper uniformly and with an equal draft over the sides of the toe of the last. Movement of the han-" dle F opposite to the arrow 100 restores the abutment and wiper plates to their original position ready to last another shoe, the operator moving the tack or nail puller and the downhold into their position by hand.

While the base and supported parts of the head may be manually adjusted laterally on the carriage prior to lasting or even after the partial rotation of the cam, in either of which cases the end clasp g is preferably left free to swivel in its socket to adapt itself to the toe when it meets the latter in rising, yet for the most expeditious operation of the machine the pin 9 will be inserted in the holes g to lock the clasp g rigidly to the base and parts carried thereby, includingthe side wipers, and the handle-lever d is permitted to remain in its elevated position out of engagea left last, as soon as it is raised toward a.

right last the clasp g on meeting the last will automatically adapt itself to the different inclination of the sides or swing of this right last and will thereby automatically swing the head to which it is rigidly attached by the pin g into corresponding position, also in proper alinement with this right last, thereby swinging the wipers into proper position with relation to the sides of the last and accomplishing automatically what would otherwise be accomplished through the medium of the handle-lever d the clasp when pressed tightly against the end of the last furnishing sufiicient power to swing the necessary parts automatically into proper position in alinement with the median line of the last.

When the machine is set to operate automatically, the end clasp g? fulfils the function of and forms one form of positioning device for automatically positioning the parts in proper operative position relatively to and determined by the last. 7 v

My machine, therefore, iscapable of either automatic or manual operation at the will of the operator, and it is evident that my invention is not to be restricted to the particular construction herein shown and described.

In another application, Serial No. 637,850, filed May 24, 1897, I have shown different means for obtaining the automatic relative adjustment of the lasting devices and last, and in said other application, Serial No. 637,850, I have claimed such automatic relative adjustment broadly and generically.

In another application, filed May 24, 1897, Serial No. 637,850, I have shown other mechanisms for accomplishing automatically the right and left adjustment herein referred to to meet the variations in swing presented by the ends of lasts, whether rights or lefts, said IIO other application containing generic claims relatively-fixed center, a lon gitudinally-movable slide -bar supported in the head, and wiper-plates mounted to swing about a common center on said slide-bar, combined with actuating means to move the wiper-plates forward and to close them over the toe of the last, substantially as described.

2. In a machine for lasting boots and shoes, a laterally -movable head mounted to be swung about a relatively-fixed center, a slidebar in the head, wiper-plates, and carriers therefor, mounted to swing about a common center on the slide-bar, and independent adjustable connections between said carriers and wiper-plates, combined withactuating means to move the carriers forward and to close the wiper-plates, lateral movement of the head about its center adjusting the wiperplates to act uniformly upon the sides of the last, substantially as described.
