For locking the cross-head 17 in position during the upward movement of the table 4, locking eanis 22 are provided secured to a rock shaft 23 mounted in the frame of the machine above the cross-head 17. which cams are adapted to he swung inwardly over the cross-head, until they contact therewith and to be swung outwardly to allow the cross-head to be raised. The. cams 22 are swung inwardly by the force of a spring 23*, and are. swung outwardly by mechanism comprising a cam on the cam shaft It), the lever 2-1 pivotally mounted at its rear end upon the oted 111 the lower portion of the machine frame of the machine and provided at its forward end with a roll engaging the cam, and a. link 25 connecting the forward end of the lever 24' to an arm 26 secured to the rock shaft 23 and projecting rearwardly therefrom.

Except. for slight changes in the shape and arrangement of certain of the parts, the

mechanism so far described is constructed the machine, however, tSllOt actuated, and j and arranged to operate in the same manner table 4 when the jack is in position beneath 3 its operating form. The table 4 is actuated at the proper times during the operation of the machine by mechanism comprising a cam on the cam shaft 10, a toggle lever 16, and a link 17, connecting the toggle lever and cam.

To automatically regulate the amount of pressure applied to the sole of a shoe and thus vided for permitting the cross-head to de"-- scend until a form is seated upon the sole of a shoe, for locking the cross-head in position during the upward movement of the table 4 chine described in the patent hercinbefore referred to. in the machine disclosed in said patent the cam shaft is driven by means of a worm meshing with a worm wheel secured to the shaft and this construction is retained in the machine illustrated in the drawings accompanying this application, the worm wheel being indicated at 37 and the worm at 28.

and for raising the cross-braid after the sole of 5 the shoe has been leveled.

'llie-forins 2 are held in position thereon by means of locking pins 19 mounted in the form carriers and en gaging holes in the straps secured to the forms, and the fUl'HIK'zll'l'lOF-s are supported from the cross-head I? so as to be capable of a slight rocking niovcnicnt as is common in this class of machines. The mechanism for permitting the cross-head 17 to descend and seat a form upon the sole of a shoe and for raising the cross-head after the sole of a shoe has been levt-lcd, comprises a cam on the cam shaft It), a lever 30 pivoted at its rear Also as in the machine of the patent,'the worm .28 is mounted upon a shaft j 29 which is driven through s iiral gears 30 from a driving shaft- 31 journa ed iirthe rear portion of the frame of the. machine below and parallel with the, aim shaft. in the machine of the patent the driving shaft 31 and the shaft 2!) are rotated constantly, the wornr i being loosely mounted upon the shaft, 2.) and a positively acting clutch being provided for connecting the worm and the shaft to start and stop the cam shaft. A clutch act'uating mechanism is provided for actuating t the clutch to stop the cam shaft with a jack and form in a pos tion 0t pressure, and a tiining mechanism is also provided which acts on the clutch actuatingmechanism to cause said mechanism to start the cam shaft after the jack and form have remained in a. posi tion of pressure for a. prcdeterminml length of time, this timing mechanism being driven from the shaft 29. in embodying th various features of the present invention in the i machine of said patent, the worm 28 has been end to the frame of the machine and provided at its forward end with a roll hearing against the cam and a link 3] connecting the Hunt end of the l vel' and the crosshcad.

rigidly secured to the shal'tg!) and a friction clutch has been provided between the driven pulley and the. driving shaft 2%]. ;\lso a.

clutch actuating mechanism has been provided for actuating the friction clutch to disconnect the driving shaft and pulley when ajack and form are in a position of pressure, and a timing mechanism driv n from the pul machine, a. spring 39 surrounding therod 38 amlintorposed between the sleeve and one 7 end to the rear end of the rod 325: byineans of ley which acts on the clutch actuating mechanism' to cause-said mechanism to connect the driving shaft and pulley after the jack and form have been held in a position of pressure for a predetermined length of time. By the provision of a friction clutch between the driving shaft and the driving btilley, and i of a timing mechanism which is driven from f the pulley, the machine can be t'l own into and out of operation without subjecting the working parts to injurious stra us or shocks. and the machine can be Optl'tiiitllii a more certain and ellicient manner. r

Toinsure the stopping of the driving shaft as soon as the driving pulley-is disconnected therefrom, a brake is preferably applied thereto, and in the constructionillustrated in the drawings this brake is connected to the clutch actuating mechanism so as to be. actuated simultaneously with the friction clutch.

It is desirable that the'rotation of the cam shaft be. stopped when the table4 is at the limitof its upward movement, and in order to secure this result and prevent any forward rotation of the cam shaft after the driv-- ing pulley has been disconnected from the driving shaft, the machine illustrated in the drawings is provided with a brake arranged to engage a disk on the cam shaft, and with mechanism for actuating the brake to stop the rotation of the cam shaft when the jack and form are in av position of pressure.

The driving pulley is indicated at 32 and is mounted to rotate looselyupon the. driving shaft. The friction clutch consists of two members, one of which is formed on -the pulley and the other of which is rigidly secured to the driving shaft so as to rotate therewith. The clutch member Which is secured to the driving shaft is indicated at 33; To connectand disconnect the driving shaft and pulley, the pulley is moved longitudinally on. the shaft. The clutch actuating mecl'ianisni for moving the pulley comprises a cam 34 secured to the cam shaft 10 outside ol'the worm gear 27, a sleeve 35 provided with an upwardly extending arm 36. and a downwardly extending arm's-57, a rod 558 7 mounted to rock and move longitudinallyin bearings supported from the frame ,of the o i the bearings for the rod, a. leveitf4t). pi vdtally mounted in the rear. portion il the. frame of the machine and connected at one pins projecting from the forked end ol' the i lever into a grooved block 41 secured to the rod, an arm 42 rigidly coni'iected to the lever 40, a lever 43 connected atone end to the. linb of the driving pulley by means of pins projecting from its forked end into a groove 3 in the. hub, and a rod 4-1 connecting the other,

end ol the lever 43 and the. arm 42. The

parts of this mecha'iiism, as'will be apparent from an inspection of lfigs. 1 and .3, are soarranged that the pulley is moved in a direciion to disconnect the pulley and driving shaf't by the. action of the cam 34 and is moved in a direction to'connect the driving shaft and pulley by the action of the spring 39. When the machine is at rest with both 1 of the jacks at the front of the machine in.

their position of presentation, the parts of the clutch. actuating. mechanism are in the position illustraieilin Figs. 1 and 3, the arm i so ol'ihe sleeve It?) being engaged by one of he projections on the can] 34;, and the rod 38 being held in the position to which ithas been moved by the cam against the force of the spring 3%). To start the machine the arm 36 is swung inwardly by swans to be hereinafter described, and is thereby moved out of engagetnmit with the projeetion on the cam 34. As soon :is the arm 3!} moves out of engagementwiih the projection on the cam 34, the rod 38 is moved to the left by the spring an'l through the connections above described the driving pulley It. is moved into engagement with the i-luti-h member 33. The driving pulley reinains in t,-ngageinent with the clutch member 32-} until the. cam shaft it) has made one-half of a. revolution, at'whieh time the other projection on the itl-Iii engages the arm so, and the rod 35 is returned to the position indicated in Fig. 1, thereby moving the driving pulley out of engagement with the clutch member 33. The arm 313, after being moved inwardly out 100 of engagen'ient with a projection on the. cam 34, is returned into the path of niovei'i'ient of the other projection by means of a'spring 45 acting on the lower end of the. arm 37, as best shown in Fig. l). r

The brake for stopping the rotation of the. driving shaft as soon as the. driving pulley is disconnected therefrom, is illustrated in. de-

tail in Fig. 1t), and comprises two brake shoes 46 and 47 pivotally mounted upon a lixed stud 4-8 and arranged to nearly surround a disk 49 se nrml to the driving shaft. 7 At the. opposite sideof the. driving- -;haft from the. stud 48 the brake. shoe 46 is pro vided with av bell crank-lever 50 pivotally1 5 mounted thereoii, and the short: horizontal arm,ofthishell crank is eo meetrtnl bylii'ikSl to the brake shoe -17. Thelong-vertical ar-molj the bell crank 50 projects through a slot in the short arm of the l \'er 4 s that th hell'12o crank fitl'is oscillat d whenever the lever +1 is oscillated. it will be a'p arent frinn tiii iiispeetion of Figs. .2; and It) that int-belt -crank 50 is o cillat d to cause the brake."

driving shaft, and that the bell crank St) is oscillated to move the brake shoes hi and 47 out. of engagement [ill the disk 4U when 13o are in a position of presentation.

&

the clutch actuating mechanism is actuated to connect the driving pulley and driving shaft.

The brake for insuring the stopping of the camshaft with the jack and form in a position of pressure, is illustrated in detail in Figs. 11 and 12, and, as shown in these figures, comprises a brake shoe 52 pivotally '56 is so located on the cam disk that the brake shoe is caused to engage the disk when the jack and form are brought into a position of pressure and the driving pulley is disconnected from the driving shaft. By means of the screw 55 the. pressure of the brake shoe upon the disk can be regulated as desired.

The projections on the cam 34 of the clutch actuating mechanism are so located that the driving pulley is disconnected from the drivingshaft when a ack and form are in a position of pressure, and against when the jack has been returned to its position of presentation. As has been stated, the arm 36 is moved inwardly out of engagement with the cam 34 by the operator in order to connect the driving shaft and pulley when both jacks jack and form is under pressure the arm 36 is also moved inwardly to connect the driving shaft and pulley, but this movement of the arm is produced automatically by means of a timing mechanism driven from the driving pulley. This timing mechanism is best illustrated in Figs. 3, 4,8 and 5). Referring to these figures 57 indicates a spiral cam or Worm secured to a shaft 58 journaled in the lower portion of the machine frame and constantly rotated from the pulley 352 by means of a chain passing over sprocket wheels 5!) and 60 secured rcspcctively to the hub of thc pulley and ashort shat-t 61, spiral gcars (S2 connecting the shaft 61 and a shalt (i3, and bevel gears 64 connecting the shaft (33 and the shaft 58. Parallel to thc shaft 58 a rod 65 is mounted in the frame of the machine so Whena Normally, the tripper is held in a position in which the teeth 67 are out of engagement with the worm 57 by means of a latch 70, the lower end of which is held in engagement with a projection 71 on the tripper by means of a spring 72 acting on the upper end of the latch. Upon the worm gear 27 an arm 73 is secured (see Figs. 1 and 2) and this projectionis' so arranged that it comes into engagement with the upper end of the latch and moves the latch to relcase the tripper 66 just before or at the time that the cum shaft is stopped with the jack and form in a position of pressure. As soon as the tripper so is rclcascd it is moved by the spring (59 to bring the teeth 67 into engagement with the worm 57, and while the tecth remain in engagement with the worm the rod (35 is moved longitudinally and the outer end ofthc tripper no bearing against the arm 37 of the clutch actuating mechanism moves this arm outwardly and the arm so inwardly until the arm 36 is removed from cngagcmcnt with the cam 34 and the clutch actuating mechanism acts to connect the driving shaft and pulley. When the clutch actuating mechanism thus acts, the rod 38 and the arms 36 and 37 carried thereby move toward the left as viewed in Figs 1 and 8, and the arm 37 acts on the triner 66 to swim it about its )lVOl/ to'a n h 7 position in which the teeth (57 are out of engagement with the worm 57, in which position it is locked by the latch 70. As soon as the tripper is disconnected from the worm 57- the rod (55 is returned to its initial position by the action of the spring -15.

It will. be evident. that the initial position of the rod (35 determines the length of time during which the cam shaft remains at rest with the jack and form under pressure. To enable this time to be varied as desired an adjustable stop 74 is provided, which is arranged in the path of movement of an arm 7'5 secured to the rod (5:1 .'ll|e st p 74 is mounted upon the shalt 5s and upon a shalt 76 which forms the pivotal support for the starting treadlcs l5, and to enable the stop to be conveniently adjusted by the operator it is conncctcd by means of a rod 77 to the lower end of an arm 7h secured to a short rock shalt 7!) to which rock shal't an adjusting lcvcr is secured 'lhc adjusting lever so is located at the front of the maclllnc in and upon this rod is pivotally lnounlcd a tripper in the form of a lcvcr (Hi, the inner ism projects.

end ol which is provided with a scrics of teeth (37 adaptcd to mesh with the worm 57 and the outer cnd of which is provided with a notch (5H through which lhc lowcr cnd ol' the arm 37 of the clutch actuating mechan- 'lhctrippcr (it; is actcd upon by a coilcfd spring (3!! which tends to hold the teeth 67 in mcsh. with the worm 57.

From an inspection of Figs. 1, I: and h, it

will be sccn that tho trippcr (H3 is so conslruclcd and armngcd that a morclncnt ol' lhc rod (35 longiludinullv will nlovc lhc Illlll 337 outwardly, and thc arm no inwardly, whct hcr or not the tcct h ()7 ol the lrippcr are in cllgag'emcnt with 11:". worm 57. 'lhc rod treadles of the machine illustrated in the.

drawings are accordingly shaped at their rear ends to cooperate with blocks 83 secured to the rod 65, the shape and arrangement of the rear ends of the tieadles and the blocks being such that a depression of either treadle moves the rod 65 longitudinally a sullicient distance to throw the clutch actuating mechanism into operation.
