LASTINGTMACHINE.

To all wlw/m t may concern.'

Be `it known that I, RONALD F. MCFEELY, a citizen ofthe United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in 'LastingfMachinea of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several be driven. The gripper .is used to seize anal* pull the upper while lasting the shank, forepart and toe of the shoe, but is not necessary for lasting the heel seat, the upper materials of which are simply wiped over upon the innersole and tacked, For advantageous use the gripper must stand open ready to receive and seize the upper` when the machine is started andl it must be ren-' dered inoperative while the heel Seat is being lasted. Also the combined wiper and tack carrier must at such time be retracted ready to advance to"its work vand be loaded with a tack when the machine starts. In last-ing welt shoes small tacks are fully inserted to fasten the heel seat, and on other parts of the shoe long tacks are left with their heads and stems projecting from the work for convenient withdrawal after the welt attaching operation. The raceway y must be adjusted to supply short and long tacks and the driver -stroke must be regulated to obtain the desired full and partial insertion of such tacks. For expeditious use these adjustments should be correlated. 'The long tacks-are inserted near the edge of the shoe and the short heel seat tacks must be located Amore remotely from the edgel but ont of the way of the heel attaching nails.

vided by which the several adjustments are correlated and provision is made for effecting these adjustments with a minimum loss of time and expenditure of energy by the machine operator. In the arrangement of the controlling mechanism and in the pro visions for correlating the adjustments are to be found important features of this invention which, together with certain more important combinations of parts and novel details of construction, will now be described with the aid of the accompanying drawings and will then be pointed out in the claims. j` I Figure l is a side elevation of a hand method lasting machine equipped with controlling mechanism, built in accordance with this invention, for the gripper, tack driver, tack raceway, and the edge gage by`wl1ich theshoe is positioned to receive the tacks at different distances from the edge of the shoe bottom.

Iiig.l 2 is a perspective view of controlling devices for regulating the operation of the gripper updraw mechanism, the length of the driver movement, the position of the tack raceway and the position of the edge gage.

Fig. 3 .is a plan view of that portion of the mechanism shown in Fig. l which deals with the edge gage and the raceway.

l Fig. 4 is a plan view of the controlling devices for the updraw regulation.

Figs. 5 and 6 are respectively side andv end elevations of the-mechanism for concolumnin the foot of which is a powershaft bearing a driven pulley, a loose pulley and connecting clutch mechanism controlled byl a treadle as in said patent. l In the head of the machine isthe cam shaft 5 to which is fast its pulley 6 connected by a belt 8 to the lloose pulley onthe power shaft. The clutch lBy'this invention controlling means is protreadle is connected with a brake releasing rod 10encircled by a spring that normally Lester? holds it depressed. The brake shoe l2, which is arranged to bear upon the inner tace ot' the pulley rim as in Figs. l, 5 and (5, is carried on a lever l ulcrumed on the machine trame and normally upheld by a light spring 13 located under it. 'lhe brake is reversely moved by a cam on shaft 5. y'lhe cam, through the brake, controls the Work receiving; position of the gripper and the combined tack carrier and wiper. rlhe cam has one high, brake-setting point and is adjusted to apply the brake at that point in the cycle of the machine at which the gripper is open and the tack carrier and wiper is retracted. The cam acts downwardly through a roll 2l and collar 'forming part oit' a vertical slide which is movably guided in the machine head and is upheld by a spring- 19. The collar transmits mtion yieldingly through a spring;` 23 encireline,` the spindle 24 and thence through an adjustable foot 25, Fig. l, which normally rests upon a slide 2G movable horizontally in the brake shoe l2 and held in place by a retaining plate 2in', lig. 8. 'l`his slide has an opening into which the wedge-shaped end ot the tl'eadle-actuated rod l() is movable to withdraw the slide `trom under toot 25 to release the brake, the slide being,` returned by its spring 27 into the path olf the brake setting cam 2O -only atter the tresdle has been released. The spring; 23 prevents a harsh action ot' the brake in case the clutch is not opened quite as soon as the brake is vapplic l. ln this construction it will be noted that when the operator depresses the treadle to start the machine the slide 2o will be withdrawn from beneath the toot 25 thereby releasingvthe brake which will be lifted by the spring,l ll. The mechanism is now tree to be started by further depression ot' the treadle to set the friction clutch in 'the usual manner as will he apparent from the showing.: ot' Fin'. l. 'through the friction clutch the operator may now, by manipulating the treadle, cause the gripper to close and perform its lasting' operations and may stop at any time required. This enables the operator to make sure that the stock is properly lasted bet'ore allowing the machine to taster the upper., complete itsl cycle and stop. This construction` therefore, givesthe operator control oi? the machine duringa substantial part o'l its cycle during which the lastmg merations of the machine are performed and provides means for automatically stopping the machine at a predeterinihed point in the cycle, for example, after 'the upper has been secured and the gripper has opened. ln a broad Way this brake setting' and releasing mechanism is ot the ltype shown in my earlier' United States Letters Patent No. 791,986 of lune 6, 1.905, but is an imprei/ement thereon in some respects.l No

claim* is made herein to the partienlar construction of this present mechanism, the right beingr reserved to cover that invention in a separate application.

rl`he cani shaft 5 has gripper cams which include the updraw cam 30 having a path in its Jiront side face through which reciprocating motion is communicated to a slide 32 to raise the rear end ot the updraw lever and thereby lower the open 1gripper to stock receiving position. As herein shown the gripper lowering torce is transmitted through intermediate stops or devices 36, Figs. 2 and Ll, which are normally held by a lspring 37 in operative position between the lever and the slide 32, or a llange on the slide. but are capable of separation and withdrawal trom such position, as indicated in dotted lines, Fig. et. When so Withdrawn the slide will reciprocate idly without lifting; the adjacent end ol lever 8.3 and the t g'rippcr will be held up in an inoperative positiom for heel seat lasting. by the stress of a spring 38 which acts downwardly upon the lever in the well-known way described in said iirst mentioned patent.

"he tack driver 5() is raised by a cam and depressed by a spring as fully shown and described in said prior patent and stops or devices 5G which are also broadly like the corresi'mndini;` parts in said patent are arranged between a collar 5l on the driver bar and the head through which the bar is guided to limit the descent ot the driver and produce partial insertion ot' the tacks carried by the reciprocating wiper (30. 'lhc pair et driver stops or devices 5U have toothed connection with one another as do thepair ot' stops or devices 3G tor the gripper and said pairs are connected together by a rod asshown in l"igs. l-anvd 2 so that when the gripper stops 36 are retracted7 and `the gripper is consequently inoperative for heel seat lasting, the driver stops are also'withdrawn and the driver makes its lull stroke for lull insertion of the heel seat tacks.

'l`he tacks are supplied to the tack carrier and wiper by a double racevvay (35 which is shit'table sidewise to present its long tack carryingl groove and itsl short tack carrying groove alternatively to the tack Separating mechanism 7() by which the tacks are taken one at a time from either racei'ay and delivered to the tack carrier, as is well understood in the art. rlhis adjustment of the raceivay is made by a rod connection Gl with a stud (38, Figs. 2 and t), mounted eccentrically in a pinion G6. 'lhe pinion 66 on a shaift 59 is turned by a segment G7 on a vertical shaft 69 connectedwitlr the rod 55 which connects together the driver stops and the gripper stops. 'lhis vertical shaft has a hand lever 78 by which it can be turned and caused to ett'ect simultaneous adjustment et the raceway to provide small tacks, `the its 'driver stops to allow full insertion of such tacks, and the gripper stops to discontinue the effective operation of the gripper.' Reverse adjustment of the vertical shaftlnakcs the opposite adjustments of said parts suitable lfor side and forepart lasting. 1f nov centric connection 77, Figs. 3 and 9, with a link 7l that extends backwardly to a lever 72. One end of the lever has an adjustable pin and slot connection 74 with a portion of the machine head, and the other end of the lever is connected to an edge gage carrier 75 which is mounted to slide from front to back on a guide rib on the lower face of the machine head. These parts are organized so that when adjustment of the controlling devices is made by means of vertical shaft 69 to withdraw controlling

devices

36 and 56 for suspending the operation of the gripper and providing full insertion of the heel scat tacks the gage carrier 75 is retracted or moved inwardly toward the bodyof the machine to allow for the insertion of the heel scat tacks inside of the location for the heel attaching nails. The extent of the movement imparted to the edge gage for this purpose can be varied by the pin and slot connection which the link 71 has with the lever 7'2 and the normal position of the edge gage carrier can be varied to suit different conditions by the adjustable connection 7 4. In addition to the forth and back adjustment of the gage carrier the usual thick 'edge gage 80, which is u'sed while lasting the heel seat but is in the way while lasting .the shankbecause it is too thick to reach into the Shanks of'many styles of shoes, is connected with the controlling mechanism so that it is brought up into position'for use when adjustment of the other parts is made for heel'seat lasting and is turned down out of the way when adjustment of the gripper, racking devices. etc., is made for shank and side lasting, the thin edge gage 79' remaining in operative position.

For this purpose the vertical shaft 69 is connccted h v a crank arm 81 and link 82, Figs.

Q and 3, with a toothed segment 84 which'v drives a rack 85; rlhe rack meshes with thc pinion 86 sec'ured to a pivot pin mounted in the front end of the gage carrier and upon which the thick gage is fastened. By these connections the thick edgev gage is turned up and downby movement transmity ted from thc vertical shaft 69.

In the use of a machine of this invention, an operator will start lasting a `shoe at one side of the shank as is the custom. For

this purpose he will find the machine at, rest with the wiper a-nd tack block retracted l to permit proper presentation of the shoe in the machine and the gripper jaws open for the reception of the upper, these conditions having been provided for by the controlling

devices

12, 20 when the machine was last brought to rest.` A single adjustment of the vertical shaft 69 and the controlling devices connected therewith will now position all of the operating parts suitably for lasting the shank by locating the gripper stops 36 in position to cause the gripper' to operate, by locating the driver stops 56l 1n position to leave the tacks upstanding for subsequent withdrawal after the welt attaching operation, by shifting the raceway to cause it to furnish long tacks required for shank and, side lasting, and by turning the thick edge gage down ont of the way of the shoe and advancing the" edge gage carrier 75 to cause the thin edge gage to position the shoe for locating the tacking line in desired proximity to the edge of the shoe bottom. The improvements provided by this invention save the time of the operator required to make the separate adjustments necessaryy formachines as heretofore built.L When the side lasting is completed and the heel seat lasting is to be commenced, the machine will again cbme torest with the tack block and wiper in retracted position and the gripper upraised with its jaws open.

A single, adjustment of the vertical shaft 69 in the direction reverse to that in which it was previously turned will now withdraw the gripper stops 36 from under the updraw lever so that the updraw cam and its slide will therefore fail to lower the. gripper 'to upper seizing position and the gripper will remain upraised out of the waycf the operator during the heel seat lasting'. Si-

multaneously with this adjustment the stops 1 56 will be withdrawn from the tack driver,

permitting the driver t0 make the length of the stroke for full insertion of the heel seat tacks. The raceway will be shifted to deliver short heel seat tacks; the gage carrier 75 will be retracted for positioningy the tacks inside the-line of heel nails and the thick edge gage will be swung upwardly into operative position. The expedition with which the required adjustments can be made and the certainty lthat the machine will always position the wiper and tack block and the gripper in readiness for receiving the workso that the'irst cycle of the machine can always be utilized, as herein provided for, enables this invention to increase the capacity of the machine.
