To all -whom it may concern:

Be it known'that I, THOMAS K. KEITH, a citizen of the United States, residingat Boston, in the county of Sufi'olk and 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 on'the drawings representing like parts. 4

My invention has for its object to provide an improved lasting machine for use in lasting boots and shoes.

' In the following specification, taken in" connection with the accompanying drawings, I have disclosed my invention as embodied in the best form of machine now known to me, althoughvit should be understood that my invention is not restricted in its embodiment -to the dparticular machine here shown and describe but may be varied within the scope of the invention here disclosed.

The machine here shown as illustrative of my invention, may be described generally as containing a cplurality or series of lastv suports, each a ast upon or'aboutwhich it 1s desired the apted to support or carry a upper of a boot or shoe shall be lasted. These last supports, with the lasts thereupon are presented in succession to suitable end lasting mechanism or mechanisms which operate to last the material over and about the end or ends of the last, the material at such time being-preferably clamped smoothly about and against the last on a line immediately below the line of action of thelasting devices by clamping members of an improved form, said members being constructed toretain the up 'er in clamped position about'the last unti the completion of the operation of securing the upper in lasted position by the fastening means.

From the lasting devices, the support carrying the last, is automatically presented to a suitable fastening means, preferably a tacker, by which the lasted upper is secured by tacks in lasted position upon the last. Upon the completion of the fastening operation, the support is returned to its original position, and during such movement the clamping members are automatically released in order that the operator may remove the lasted shoe .from' the support and substitute therefor another last having thereon the usual parts of a shoe to be lasted.

The movement of the support to carry the .the former case starting the operation of the fastening means and in the latter case suspendin the operation thereof.

The lasted material is preferably retained by the clamping members about and upon the last during the interval required for the transfer of the last from the lasting devicesto the fastening means, in order that there may be no danger of the -material slipping from its lasted position. Preferably the fastening means or tacker is also made to perform the function of a lasting device, and to this end, under the embodiment of the invention herein disclosed, it comprises a casing which terminates in a widened portion to constitute a wiper. A

reciprocating driver is located within the casing, the driver being actuated by suitable mechanism operating to cause it to drive tacker, as here defined, is by appropriate mechanism given inward and outward move ments relatively to the edge of the last in order that it may, during its inward movements, wipe or press the material of the up per smoothly down upon the innersole, and at the termination of such wiping and pressing movements the driver is actuated to drive a fastening through the upper and innersole. The end of the tacker engages the upper at the extreme edge of the innersole and is maintained in continuous engagement with the upper from such extreme edge to the end of its inward movement, where the fastening is driven, the wiper being then lifted from the upper and returned out of contact therewith until it reaches the position to repeat such operation.

In order that the inward and outward movements of the fastening means, or tacker, may always take place at different port-ions of the last in the direction of its lng movement of the fastening means, or

prehends the provision of suitable mechauism whereby to insure that the inward movement of the fastening means shall always be substantially at a right angle to the adjacent portion of the periphery of the last. p a

A further feature of the invention (5011] prises the provision of instruim-ntalities for imparting a step-by-step traveling movement to the fastening means. and means for automatically controlling this step-by-step movement according to the length of the shoe upon the shoe support which is in position to receive fastenings from the fastening means.

Preferably tacks of different lengths are eiuployed, the longer tacks being utilized in the vicinity of the ends of the lasts, and the shorter tacks along the sides thereof,

and means is herein shown for automatically selecting the longer or shorter tacks as the lasting at any particular point may require.

The machine of this application constitutes an improvement upon and a development of the machine shown in application Serial No. 633,693 filed April 24, 1897, and all broad claims to subject-matter common to the two applications are found in the earlier case; also those features of this invention which relate particularly to the tacking mechanism are covered by Patent No. 978,297 which was granted December 13, 1910, upon a divisional application, While those features which involve improvements in shoe supports are covered in divisional application Serial No. 589,682 filed October 29, 1910.

Other features of the invention, including important combinations of parts and details of construction, will be hereinafter more specifically described and claimed.

' Referring to the drawings, in the machine there shown as illustrating my invention,

A is the bed, of suitable shape and construction to sustain the various parts of the machine. Upon this bed A is erected a suitable column a, the 'upper end of which is provided with a vertical pivot stud 0/ shown in dotted lines Fig. 2, and upon which is pivoted to rotate horizontally, the carrier B. This rotating carrier B carries a plurality of last supports, herein shown as two in number and of similar construction, hence a description of one will be sufficient, it being understood that corresponding. parts of both supports are similarly lettered.

Referring particularly to the last support at the right Figs. 1 and 2, and also to Figs.

.5 to 8 inclusive, said last support consists of a movable base 7), shown as a turn table, having a depending pivot or journal stud b looselyjournaled in the end of the carrier B, said table consequently rotating about a vertical axis in the carrier B which latter is itself rotatable.-

Referring now particularly to Figs. 5 to 8 inclusive, the table 6 at one side has erected upon it a stationary post 6 thread ed at its upper end to receive the rotatable nut 5 the upper end of which is provided with a suitable heel pin 1) adapted'to enter the usual socket in the heel end. of a last, to hold the latter in position as indicated in dotted lines Fig. Rotation of the nut 6 causes vertical adjustment of the heel pin 6 and corresponding vertical adjustment of the heel end of the last.

At its side opposite the heel support described, the table I) is provided with a second post I), recessed at its upper end to i receive freely the lower end of 'thevertical adjusting screw 1), supporting at its upper end the toe rest or block b of suitable shape and construction to support properly the toe end of the last, as indicated in dotted lines Fig. 5. A nut b threaded upon the screw 6 rests upon the upper end of the post 6 and supports the screw and the toe rest- 6 of the sci'ew and likewise ofthe toe rest I)", to acconnnodate the various lasts. The toe rest is restrained from rotation and is guided in its vertical movement, by two guide rods 6?, which work in suitable apertures in the top of the post 71 C otiperating with each last support are slnnlarly constructed clamping or holding means which I will now describe, referring still to Figs. 5 to 8 inclusive, said clampin means, as I have herein chosen to illustrate the same, constituting also a guide or track which conforms to the outline of the bottom of the last. The heel post I) carries ahorizontal pin 0 upon which are mounted, at opposite sides of the post, like levers a, the upper ends of which are connected by links 0 with the free ends of the heel clasp, shown as composed of like segments or members 0 jointed together at the middle or back of the heel, as indicated at c, Fig. 6. Movement of the levers 0 away from the heel of the last in the direction of the arclasp members 0 to open and release the heel of the last and the material thereupon;

opposite or forward movement of said levers acts to close the heel 'clas tightly about the heel end of the last an the material thereupon. The toe post I) is likewise provided at its base with a transversely extended pin, indicated at 0 upon which are pivoted, 'at opposite sides of the post, similar levers 0, shown as broken away in Fig. 5 to expose parts between the same. The upper ends of these levers c are loosely connected by links 0 with the free ends of the toe clasp members 0 jointed together at I c in a manner similar to that described with reference to the heel clasp members. Movement of the levers c in the direction of the arrows thereon away from the toe of the last, acts to separate and open the toe clasp members away from the toe of, the last, and opposite movement thereoftoward the toe of the last acts to close the toe clasp members about the last and the material thereupon.

The clamps for the sides of the last are shown as composed principally of the links or members d, d, (P, flexibly connected or jointed together, asshown in Fig. 6 said members presenting exterior corners between the flat topedges and vertical outer sides thereof, such shaped guides or members enabling the feeler end, to be described, to ride accurately thereover and retain proper engagement therewith during the lasting operation. The links (i and d at opposite sides of the last, and consequently the connecting links (Z are pivotally supported by vertical screw bolts upon the upper ends of levers d 03*, the levers d being rigidly secured to like and parallel horizontal shafts (i Fig. 6, journaled in suitable hearings on the table 6, while the levers d are loosely mounted upon the said-shafts, but are connected therewith each through the medium of a pin d playing in a recess. or pocket d of a collar (i fast on its shaft (l While every rotative. movement of either shaft d is communicated to its lever (P, the lever (l thereon is moved only when the walls of the pocketd in the collar (i contact with one or the other side of the pin (i so that there is a certain amount of lost motion between the levers d and their respective shafts d, to enable the side clamps the more readily to fit the varying contours of the lasts, along the sides thereof. Obviously the number of links or members composing the side clamping devices and the shapes thereof, may be varied as desired and according to the various contours of lasts upon which it is necessary to clamp the material.

The levers (5 d, are provided respectively with heels d", between which and the table are, interposed suitable springs (i which tend constantly to throw the, upper ends of the levers and the clamping members carried thereby, inwardly, toward and against the sides of the lasts or the material thereupon.

To remove the levers and clamping members'fromthe sides of the lasts, Ihave provided the toggle levers d, Fig. 6, connecting the levers (Z at opposite sides of the last, and which when straightened separate the said levers and by rotating the shafts 61 also separate the levers d and consequently the side clamping members d, d, d

To operate the toggle levers d, I have provided the operating lever 01 pivoted at 01 to a post erected on the table, said lever d having an arm at which is connected with suitable actuating mechanism which will be hereinafter described in connection with the operation of the machine.

To draw the toe and heel clasps toward their respective'ends of. the last, I have provided the bail 0 Fig. 5, having its ends ointed respectively to the heel clasp levers 0'. Connected with the crown of this bail is the rod 0. which is extended horizontally through a vertical slot in the toe post 6 see Fig. 5. A' spring 0 is interposed between one face of the toe post If and a collar 0 fast on the rod 0 and a spring a is inter posed between the oppositeface of the said toe post 6 and a yokec connecting the like toe clasp levers 0 said springs tending normally to equalize or center the bail and rod 0 with'reference to the toe post 6 The outer end of the rod 0 at the left Fig. 5, is

provided at its underside with ratchet teeth 0 adapted to be engaged by a dog a" o a,

' collar 0 slipped upon the said rod 0 This collar, held by said dog, serves as a back support for a face cam a surrounding the the material at rod 0 and provided with a suitable handle 0 by which it ma be rotated about the rod Rotation of this face cam 0 in one direction, for instance, upwardly, as indicated by the arrow Fig. 7, causes its cam face to cooperate with a corresponding face on the yoke 0 to force the said yoke and the toe clasp toward the toe of the last, and at the same time draw the rod 0 and the bail 0 in the opposite direction simultaneously to draw the heel clasp against the heel end of the last, thereby simultaneously clamping both the heel and toe ends of the last. Opposite movement of the handle 0 and its cam 0 effects a release of the heel and toe clamps or clasps. By means "of the dog a the position of the collar 0 on the rod 0 may be varied to accommodate the. toe and heel clasps to lasts of varying lengths.

To facilitate the release of the heel and toe clasps I have extended the toggle joint pin d Fig. 6, vertically above the toggle levers, so that when the said toggle is straightened to release the said clamps, the inwardly moving pin d will act upon the cam surface 0 of a lever 0 pivoted at 0 to the bail, and will lift the said lever causing its free end to engage the tail of the dog a and disengage the said dog from the ratchet teeth on the rod 0, thereby freeing the collar 0 and face cam 0 and permittingthe springs 0 a, to throw the heel and toe clasps quickly away from their respective ends of the lasts. After the parts have been thus released, obviously it is necessary to return them approximately to their former positions before rotation of the face cam 0 will become operative to clamp the toe and heel clasps against the opposite ends of the last, and to accomplish this quickly I have provided the lever 0 Fig. 5, pivoted at 0 to the base of the post 5 and which, whenstruck by the hand. of the operator, operates to push the collar a and the cam 0 the yoke 0 its levers 0 and the toe clasp quickly to the right, until the toe clasp brings up against the toe of the last, when the parts are automatically locked in'that position by engagement of the (logo with the ratchet teeth on the rod 0.

Thereafter, rotation of the cam about. the

rod 0 will draw the heel and toe clasps mg on the table I). 'A dog- 6 pivoted to the f, Fig. 1, they bein base of the toe post 6, is held by a spring nect ed by links f which in turn are con b'n0rmall v in engagement with a series of ratchet teeth 6 shown in dotted lines, Fig. 5, and formed in or on the table 5, whereby the post I) is prevented from accidentally moving too close to the heel post, as for instance during the time when the last is removed from the support, said dog, however, not interfering with the free movement of the toe post away from the heel post when necessary to accommodate longer lasts. This relative adjustment of the toe and heel clasps to accommodate lasts of different lengths necessarily requires that the effective length of the side clamping means be extended to thereby accommodate lasts of different lengths, said extending means being herein represented as a series of fingers e, pivoted loosely upon pins 6 carried by the levers d at opposite sides of the last. Springs 6 are interposed between. the respective levers d and the nearest fingers e to retain the latter frictionally in any position into which they are moved. Then it is desired to move the toe and heel clasps closer together to accommodate a shorter last, one or more of the fingers e at each side of the last is turned down into a' horizontal position, the fingers next to the toe clasp being first turned down, and thereafter the second and then the third fingers at each side of the last. These fingersconstructed as herein described, serve not only as clamping members but also to preserve the continuity of the last shaped guide or track formed about the last by the clamping members and clasps, as will be more fully hereinafter described.

Referring now to Figs. 1 to 4 inclusive, the end lasting mechanism is constructed and arranged to operate upon the upper on the last only while the last is carried by the last support which may for the time being, he held in the position indicated at the right of Figs. 1 and 2. The construction of this end last-in mechanism will best be understood by re erence to Figs. 1 and 3. Referring to the latter figure, f, f, are two treadle levers fulcrum at f to the base of the column a. These treadle levers have connected to them by universal joints f, the lower ends of the supporting rods f to the upper ends of which are connected by pivots f the supporting plates f which carry the lasting mechanism. This lasting mechanism may be of any suitable or desired construction capable of lasting or turning inwardly and downwardly the material at or near the ends of the last. I have herein shown such mechanism as of the wellknown wiper type, the wipers being indicated at caused to close and open as they are a vanced and retracted by studs 1", f, working in slots f, f, in the top plates f These studs are connected by other links f with the actuating block f which is given aforward and back reciprocating motion by and from a suitable hand lever f connected therewith 70 by a link 1. The vertical inclination of the lasting plates for the toe and heel, to accommodate the spring at the ends of the last, is varied by means of the adjusting screws f" interposed between the plates f and suitable stop surfaces formed by bending the rods f as shown in Fig. 3.

The normal positions of the end lasting devices are shown in dotted lines Fig. 3, wherein the supporting rods f are swung apart about their respective fulcra at the universal joints f thereby removing their respective end lasting mechanisms free and clear from the last support and connected parts. The lasting mechanisms may be brought together and in close proximity to the ends of a last, preparatory to lasting, by swinging the supporting rods f toward each other into their full line positions Fig. 3, where they are automatically caught and retained by the dogs f thereon cooperating with the locking teeth f on the locking bar f carried by the column a. These dogs may be released by the operator, for the withdrawal of the lasting mechanisms, in any suitable manner, as by the handles f.

lVhen the upper and inner sole have been assembled in the usual way upon a last, the latter is first placed upon the last support, which is at the right, i. e. the front of the machine, as the operator stands at the right hand end of the machine Figs. 1 and 2. The operator next moves the handle (7 to force the toe clasp against the toe ofthelast, and the cam handle 0 to tighten both the toe and heel clasps against their respective ends of the lasts. He then releases the toggle (1 in a manner to be-hereinafter described, to permit the springs d to throw the side clamps against the material at the sides of the last, the operator-at the-same time, with the assistance of his pincers, or in any other suitable manner, drawing the sides of the upper upwardly about the body of the last in order that the same may be held by the side clamps in a stretched condition upon the last. With the material thus held firmly to the last in a plane or line just below the bottom of the last, or just below the line of action of the lasting wipers, the operator swings the supporting rods f, carrying the end lasting mechanisms from their dotted line positions toward each other into their full line positions Fig. 3, thereby bringing said end lasting mechanisms up to the respective ends of the last where they can be operated to last the material thereupon. Of course the clamps and clasps referred to are still in position holding the upper to the last. The operator now, through the memeans or tacker.

dium of the handle levers f, Fig. 1, advances and closes the toe and heel plates to lay the material at the toe and heel of the last, and after the material has been crimped and laid down upon the upturned bottom of the last or upon the innersole thereon, it is there compressed by depression of the treaclle levers f, f, by the foot of the operator, which act through the rods 7' to correspondingly depress the entire lasting mechanisms, causing the heel and toe wipers f to press the crimped and folded material tightly down upon the innersole, the compression continuing only so long as the operator holds the treadles, or either of them depressed. The arrangement of the pawls causes them to force the lasting mechanisms farther overthe shoe when depression by the treadles f is efiected, as will be obvious from Fig. 3. After the compression, the treadles and wipers are raised by springs f", Fig. 2, the lasting plates are then withdrawn, and with the toe and heel clasps and side clamping members still in position clamping the upper tight-1y against the sides of the last, thereby holding the upper in its lasted position, the operator releases the dogs f holding the lasting mechanisms up to the last, thereby permitting the lasting mechanisms to fall away from the last into their dotted line positions Fig. 3 by their own weight, after which the carrier B is rotated to carry the last support with its lasted and clamped shoe into the position at the left Figs. 1 and 2, for the purpose of having its upper tacked or secured permanently in position or to the innersole, the shoe previously lasted and swung into such position and now having its upper permanently secured, being at the same time swung to the right into position in front of the operator, where it is removed and a new last, upper and innersole placed in position and lasted while the one previously lasted is being tacked or secured.

I will now describe the mechanism or means which acts upon the lasted shoe when carried away from the operator by rotation of the carrier B, to secure one lasted upper to the inner. sole while another upper is being positioned and lasted by the operator. This mechanism is shown at the left Figs. 1 and 2 and in detail principally in Figs. 9 to 15 inclusive. Referring first to Fig. 2, the bed A at one side the column a is provided with a suit-able bearing a for a shaft h, upon which is fulcrumed one end of each of two links h", Fig. 18, said links at their free ends carrying a second shaft h which serves as a fulcrum or pivotal support for the oscillating or in and out moving double standard if for the fastening At its free end, Fig. 2, the oscillating standard h constituting sustaining means for the fastening means is provided with suitable guideways 71. for a head h free to travel to and fro or slide in said standard and suitably shaped and constructed to hold the preferably inclined driver tube or tacker casing 715, best shown at the right Figs. 9 and 10. This tacker casing h may contain usual tack or fastening driving devices, I having for convenience herein shown said casing as provided with a proper nose h, preferably widened, as shown in Figs. 13 and 1 1, the better to serve as'a wiper to meet and wipe the material of the upper over and lay it upon the innersole, and within said casing reciproca tes the driver h", Fig. 13, connected with and actuated by the reciprocating driver carrier k This driver carrier is actuated by a bell crank lever h, Fig. 10, connected with the upper end of the carrier, and fulcrumed at 72. in a part of the head h; A spring 72 tends constantly to move the driver and its carrier into their lowermost or tack driving positions, they being lifted therefrom into their elevated positions through the medium of the bell crank lever 72., the lower end of which is provided with a roller h which runs in contact with a suitably shaped driver cam 71,, shown in dotted lines Fig. 10, fast on a shaft-h journaled in suitable hearings in or on the head 12.. 7 its hearings in an upright h of the head h is extended at one end beyond said head, as indicated in Figs. 9, 3 and 4:, said shaft having a groove as h which receives a key or spline fixed to a sprocket wheel h, driven by a sprocket chain h from a sprocket wheel 72." fast on the shaft h, Fig. 19, hereinbefore referred to, said shaft dur ing the traveling movement of the fastening means sliding through the sprocket wheel, this being necessary in order that the sprocket wheel may rotate the shaft h in all positions of the tacking means during its traveling movement in one and then in an opposite direction. The shaft 72., Fig. 2, is shown provided with a gear wheel h inmesh with and driven by a Wheel it fast on the shaft h, which is the main shaft of the machine.
