SPECIFICATION forming part of Letters Patent N o. 601,938, dated April 5, 1,898. Appnmion sie@ January 15, 1997. sam No. 619,296. (Nb model.)

To a/ZZ whom it may concern: y Be it known that I, MATTHIAS BROCK, of Boston, county of Suffolk, State of Massachusetts, 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. This invention relates to machines for lasting boots and shoes, the invention having especial bearing upon the devices for operating inthe vicinity of the ends of the last.

In my experiments conducted with the idea of improving lasting machinery I have found that certain advantages are to be gained by giving to the lasting devices and last a relative rising--and-falling movement in an inclined direction as distinguished from a truly vertical direction,as heretofore-for instance, by giving the lasting devices such an inclined rising-and-falling movement that they may be made to move away from or clear themselves of the last when dropped in their lowermost position, or they maybe made to follow during their upward or rising movement approximately the'inclined line of an overhanging end or portion ofthe last. One means of producing this rising-and-falling movement in an inclined direction is by providing a fulcrum about which said lasting devices are made to rise and fall, this fulcrum movement also presenting the added advantage that it presents less weight of parts to be moved and" less friction; hence is more easily and conveniently manipulated.

My invention vfurther relates to a lastingmachine having an end clasp adapted-to embrace the end of the last, the same having the capacity for a combined opening-and-closing movement for adapting itself to wider and narrower or larger'and smaller lasts and a swinging movement. to. adapt it for right or left lasts. f

The features of my invention will be hereinafter more particularly described, and pointed out in the claims.

In the drawings, Figure l, lin side elevation, illustratesone embodiment of my invention; Fig. 2, a top or plan view of the parts .view similar to Fig. 2, with the top plate and parts carried thereby removed; and Fig. 5,a

detail illustrating one manner of mounting vthe end clasp in accordance with my invention.

Referring to the drawings, in the particular embodiment of my invention selected for illustrationr herein, A is a sliding carriage mounted to slide in the direction of the length of the last in suitable bearings or supports, (not shown,) said carriage at its outer end being shown as provided with avertical bracket A', provided with a suitable guideway for the vertically-adjustable slide a, held in vertically-adjusted position in suitable manner, as by the clamping-screw a. To the upper end of thisslide a is fulcrumed at d2 a yoke a3, provided at its lower end with a suitable bearing' for the reception of a trunnion-pin b on the outer end of the head B, the latter having a rolling movement on said trunnionbearing in the yoke a3 and a rising-and-falling movement with the yoke d3 aboutthe fulcrum a2.

At its opposite side edges the head B is suitably grooved for the reception of the sliding cam-plates h', held at their upper edges in position in said grooves by the'top plate or cover h2, suitably secured to the head, and held laterally in said groovesby the side plates b3, also secured'to the head. These sliding cam-plates b at their ends adjacent the last or form L are shown as provided each with an inclined or cam slot b4, the cam-slots in the two plates on opposite sides of' the head being inclined in opposite directions, said cam-slots receiving the pins b5 on the upper ends of the links o6, which constitute the lifting or swinging supports for the free end of the head, said links .h6 being jointed at their lower ends to the arms 57, fast on a shaft bs, journaled in suitable bearings b9 on and preferably constituting a part of the sliding carriage A.v

In a bracket blo, depending from the under side ofthe head B, is journaled the shaft bu, having fast upon its opposite ends the arms 612, one at least of which is shown as and IOO preferably fitted with a handle by which said shaft may be rocked. These arms Z212 rise in suitable engagement with the sliding camplates b', so that when said shaft is rocked by means of the handle described it will cause simultaneous forward or backward sliding movement of the cam-plates b',which, through their cam-slots acting in connection with the pins b5 on the swinging supports b for the head, will cause said head to be rolled in one or the other direction, according to the direction of the sliding movement of the said camplates, this rolling movement being caused by the opposite inclination of the cam-slots, which when the cam-slots are moved in the same direction cause one side of the head to be raised and the other to be lowered. The links or swinging supports 116 are themselves held against any considerable lateral movement by or with said cam-plates by the wallsV shown.) By depressing the rod c( and its end 1 of the lever referred to, the shaft 198 will be.`

rocked to operate, through the arms 117 and the swinging supports b, to raise the free end of the head B about the fulcrum a2, While depression of the rod e5 will cause depression l or lowering of the free end of the said head1 'also about said fulcrum, and this rising-andfalling movement of the free end of the rod B is in no wise aifected by the roll which may have been previously given to the said head,` by the parts described, because herein thel swinging supports cooperate with and in effect constitute a part of the means for imparting the roll to the lasting-head.

' The end of the last is preferably held upon asuitable end support, as S, of suitable shape and construction, it, as herein shown, being adjustably connected at s with the `sliding carriage A.

Referring now particularly to Fig. 4, the

head B is shown as provided at its upper side with a longitudinallyssliding top plate B', guided at its edges by the gibs BX, said slid-1 ing plate being provided with a semicircularl groove d, which receives the correspondingly- 1 curved blocks d on the under side of and seg cured to the end lasting devices, shown asl wiper-plates D D, suitably shaped at t-lieiri edges adjacent the last to meet and operatel upon the material to be lasted about the end l of the last.

The curved blocks d' are shown as provided with pins cl2, which are engaged by the forked ends of the levers (Z3, fulcrumed at d4 and having their opposite or outer ends provided with suitable slots to receive the pins Z5 on the longitudinally-movable actuating-slides d6, arranged in suitable guideways in the gibs BX. These slides d6 are shown as provided with projections (t7, which rise through suitable slots in the cover b2 and at the top of said cover enter slots d8 (see Fig. 2) in the opposite ends of the adjusting-lever d, fulcrumed upon the center pin or stud d10, carried by the head and passing through a slotv du in the sliding plate B referred to.

The lever df is extended at one or both its ends to furnish means by which the operator can readily and simultaneously slide the blocks or slides d6 in opposite directions to thereby change the relative positions of the pins d5 and through the levers d3 swing the lasting-plates D to a greater or less extent to adapt the median line of the opening between said plates more or less to approximately the median line of the last, eithera right or a left.

The lever di is locked in one or another of the positions into which it is moved after having adapted the lasting-plates D to the shoe to be lasted by means of a suitable locki ing device (shown as a latch (Z13, Fig. 2) which engages one or another .of the series of teeth C114 upon oneof the side plates b3 of the head.

A spring d, Fig. 3, interposed between the lever dg and the nut d1, fitted on the top of the fulcrumed stud d10, holds the latch CX13 in normal engagement with the series of teeth d, but permits disengagement of the latch .and teeth by slight raising of the said lever when it is desired to move the latter. v

Referring again to Fig. 4, the sliding plate B', which carries the lasting-plates, is provided at its rear end with a rising stud c, upon which is pivoted the lastinglever E, fulcrumed at one end upon the stud e', rising from the head B through a slot e2 in the sliding plate B'. By means of this lasting-lever E the operator is enabled to move the plate B forward and back at will, causing the levers cl3, fulcru med upon the said sliding plate and held at one of their ends by the fixed pins d5, to move the lasting-plates inwardly and outwardlythat is, to 4close and open the "same for lasting the material over and upon the last in a manner Well understood by those skilled in the art.`

Referring now particularly to Figs. 3, 4t, and 5, F is a suitable end clasp arranged in a recess in the front of the head on the sliding carriage, the same being herein shown as coniposed of a strip or band of leather or other suitable liexible material f, (see Fig. 5,) backed up by a chain f', the latter at its ends attached to the inner short ends of a pair of levers h h, fulcrumed at h in the ends of the curved arms h2, the latter in turn fulcrumed upon a pin 71,3, fast on the end of a slide-bar 1 71.4, arranged to slide longitudinally in a suitable guideway in the upper side of the head B. The long arms or tail portions of the levers h h are connected by a spring h5, which tends to normally open the clasp F.

. The rear end of the slide-bar 7a4 is provided ICO IIO

with adepending lug h5, (see Fig. 3,) adaptedl for engagement by the upwardly-extended curved finger m, fast on the outer end of a lever m', loosely fulcrumed upon the shaft bi1, carried at the under side of the head B, said lever at its end opposite the finger fm, being provided with an aperture m2, which receives the rod m3, held loosely by and between the posts m4 on the sliding carriage A. The

curved finger fm is adjustably connected with the lever m to provide for necessary adjustments by means of the screws m5 on the finl vger passing through suitable slots (shown by dotted lines, Fig.l 3) in the lever. As the head B is swung upwardly about its fulcrum a2 the raising of the shaft b by and with said head causes the lever m', held at one end by the fixed rod m3, to be rocked or turned to cause its curved finger m to engage the lug h5 on the rear end of the slide-bar h4 and carry the latter forward in'and with relation to the rising head, thereby, through the curved arms h2, carrying the levers h and the clasp bodily forward to embrace the end of the last, the pressure and closeness with which said clasp embraces the end ofthe last depending upon the adjustment of the parts as'pr'ovidedfor' herein provided the arms h24 with lugsh,

which depend through suitable openings in the head B, and beneath the latter said lugs are right and left threaded to receive the right and left threaded ends of an adjustingn screw k7, squared at its ends Aor.- otherwise suitably formed to enable it to be rotated to vary the opening orv separation of the said arms h2, they being moved to open or close the entrance to the clasp according as the said adjusting-screw 717 is turned in one or the opposite direction. Y

The operation of my invention as herein embodied is as follows: The last with'the `ma'- terial to be last-ed thereupon is arranged upon a suitable -usual jack or support with its end, herein shown as the toe end, firmly held down upon the toe-rest S, the lasting devices being down and back out of the way; The operator now preferably engages the handle-lever 1912, and through the parts connected there-- dle, (not shown,) depresses the rod c6, Fig. 1,1 and through the swinging support 5G raises' the free end of the head with the parts thereupon, causing the curved finger m-to-press the clasp F forward toward the last simulta` neously with the upward'or rising movement of the clasp by the upward swinging of the the end of the said last.-

'ment of the said clasp the material will be wiped tightly and smoothly upward and about It will be noticed that this upward swinging movement of the head B with the lasting devices and clasp is about the fulcrumc, the axis of which is arranged (see Fig. l) preferably above the level of the bottom of thelast at the end'thereof, so that during the upward swinging movementlthe parts have also a movement toward the end of the last, the curve or arc of the rising movementV of the device shown approximatiig the line of an overhanging ende. g., of the toe of a last-so that when fully raised the parts have movedinwardly beyond the most'extreme part of the end of the last to hold the material under the overhang tightly against the last. Having raised the parts so that the'lasting-plates are at or about the level of the bottom of the last the operator, bymeans of the lasting-lever E, moves thesliding plate B bodily'forw'ard to cause the lasting-plates D to close. over and upon the last to lay the edges of the upper. or vother material acted upon down tightly upon the bottom of the last, this closing movement of the plates D being repeated as many times as desired prior to the tacking or otherwise securing of the upper upon the bottom of the last. By means of the lever dgoperating inthe manner described the lasting-plates D may be either prcliminarly or at anytime during their subsequent movements swung more or less to the right or left to adapt them tothe median IOO line of a rightor left last, so that they shall .j

more effectually move'in from the sides of the last, this adjustment for rights and lefts taking place, preferably as herein shown, about an imaginary or actual center which is substantially under or coincident with the middle ofthe toe of the last. The clasp F may be opened and closed for wide and narrow-lasts by means'of the screw k7 described,`and the said clasp is further adjustable as to thel direction in which it opens to meet right and left lasts by reason of itsbein g mounted upon the arms h2, fulcrumed at h3 on the slide-bar h4. As the clasp'moves forward to'meet the end of the last it has a bodily-swinging movement, together with `its carrying-levers h and arms h2, about the center h3 to adapt itself to the last end in whichever direction said last en'd may point, so that said clasp is auto- IIO matically adjustable to meet right and left lasts, and since this adjustment of said clasp is about a center substantiallyunde'r the middle of the toe of the last this adjustment for rights and lefts is effected without chafing or injury to the material of the last. The clasp at its under side preferably rests upon a suitable support-for example,the extended end of the slide-bar h4, which-,holds the clasp in proper position during its upward-wiping lnovement.

A clasp constructed and mounted as herein described possesses double advantagesviz., it is capable of expanding and contracting to fit the varying` widths of last or to adapt itself to different curvatures at the ends of the lasts, and it also has in addition thereto the swinging movement to adapt its median line to the median line of the last end, whether the last be a left or a right, so that I have the adj ustability for the-width of the last entirely absent in clasps, so far as known to me, heretofore made adaptable for rights and lefts, and I further have the capacity to adjust for rights and lefts heretofore, so far as I am aware, entirely absent in prior clasps which are adjustable to meet varyin g widths of lasts. While I have herein shown and described my invention in connection with one embodiment thereof, in which embodiment the relative adjustment between the lasting devices and the last is effected by the movement of the lasting devices instead of the last, my invention is not necessarily limited to this embodiment, for it is evident that the same may be varied in many ways without departing from the spirit and scope of my invention.

In the apparatus herein illustrated and described the wiper-plates D, which are one form of lasting devices, act during the upward-swinging movement cf the head to engage the material upon the last and wipe the same ahead of them, so that when they subsequently move inwardly to lay the material upon the bottom of the last they move below any wrinkles which may have been put into said material in the upward wiping of the same about the last end, the upward-wiping movement of said lasting-wipers taking place in an inclined direction, which may approximate the overhanging of a last end.

The clasp F, which constitutes a form of u pward-wipin g means and which is independent of the lasting devices or wiper-plates, also, and I believe for the first time, has an inwardly-inclined movement relatively to the last, which may approximate the line of overhang at the end or any other part of a last or form.
