MATTHIAS BROCK, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY COMPANY, OF PATERSO'N, NEW JERSEY, A CORPORATION OF NEW JERSEY.

LASTING-MACI-IINE SPEED-CONTROLLING MECHANISM.

To all wiz-m t may concern Be it known that I, MATTHIAS BROCK, a citizen of the United States, residing at .we Boston, in t-he county of Suffolk and State of Massachusetts, have invented certain Improvements in Lasting-Machine Speed-Controlling Mechanism, of which the following description, in connection with the accompanying drawings, is a specification, like refcal driving mechanism is caused to actuate operating tools at one or another speed according to the position to which a treadle is depressed. In the use of this particular lasting machine the operator'h'olds the shoe in his 1 f'. hands for the action of the gripper and tack driver upon it and this presentation of the shoe requires skill and involves substantial physical eiiort when continued throughout a days work. It is therefore important to make s: other conditions as easy as possible for the One of the desirable conditions operator. is freedom to stand squarely and firmly upon both feet. It hasbeen found in practice that a substantial degree of fatigue results from the use of the invention of said patent andil the practical value of that invention is substantially reduced by reason of the fact that while using one of the speeds provided for, the operator must stand on the heel only of one foot to maintain the treadle in a mid position.

It is the specific object of this invention to overcome this difficulty by providing a'- rm and complete rest for the o perators treadle controlling foot in all positions of the treadle.

More broadly, it is an object of this invention to improve speed governing mechanism generally wherever the invention can be applied.

The several features of the invention willl be explained in connection with the accom@ panying drawings showing a plurality of embodiments thereof and then the generic invention, together with one species thereof Specification of Letters Patent.

Figure 1 is a side elevation of the lower "1' portion of a lasting machine of the hand method type such as shown in said patent and equipped with the variable speed mechanism which forms the subject-matter of that patent, together with a treadle stop Il' made in accordance with this invention Fig. 2 is a side elevation showing a pre`J ferred embodiment of this invention; Figs. 3 and 4 are perspective views showing inoperative` and operative positions respectively 'f'l of the treadle stop shown in Fig. 2; Fig'. 5 shows a third embodimentof the invention comprising a treadle with two foot plates arranged at different distances from the floor; Fig. 6 is'a perspective view of the si treadle controller shown in Fig. 1 and gov- -erned by the knee of the operator; Fig. '7 is a diagrammatic view indicating the lateral displacement of the speed controller effected lby partial and by full depressions of the treadle.

The shaft 2 having the fast pulley 4l turned continuously by belt 5 and having, the fast clutch element 6 is the driver and voperates through loose pulleys 8 and 10 which alternatively coperate with the fast clutch element 6, to actuate the large or the

small pulleys

12 and 14 for turning shaft 15: to operatethe gripper and the tacker of the The clutch element 6 normally occupies the central relation to pulleys 8 and l() which is shown in Fig. 1V

and this position is maintained by forceA transmitted through the lever 16 pivoted on the link 17, through the treadle rod 18 and the treadle 20 from the spring 22 that eX-' tends from the treadle to the frame and holds the treadle uplift-ed. These parts are or maybe all as described in said patent.

In the form Shown in Figs. 1 and 6 a treadle stop 25, comprising a hook to eX- tend under and into supporting engagement with the treadle foot plate, is adjust-ably at, tached to a lever '26 pivot-ally connected with the machine column at 27 and having its up per end in the path of a second lever 28 that extends into the knee fork 30 in which the operator rest-s the knee of the leg by which he stands on the treadle 20. Inward pres-l `sure by the knee swings the stop 25 under the treedle 2O from which position it is Withdrawn by spring 32 when pressure is relieved.

In the construction shown in Figs. 2, 3 and l a treadle stop 35 is pivoted between ears 36 on one lateral side of the treadle footplate and is held by a spring 38 in the position shown in Fig. 3 and in full lines in Fig. 2. The stop 35 has en arm which e.\:- tends inwardly and is inclined upwardly over the foot plete of the treadle in position fer the operator conveniently to engage end Swine the ermupvrdly and .the body Q th'e's'top 'downwerdly engage the door by e. pivotal movenlenl: ofthe forepart pf the feet which is 0.11 the .tremila while his Weight continues to rest upon the heel of that foot.
