This invention relates to sole pressing machines and is illustrated herein as embodied in a machine of the type disclosed in Letters Patent of the United States No. 861,746, granted July 30, 1907, upon an application of B. F. Mayo.

Machines of the type illustrated in the abovementioned Letters Patent are provided with twin sole pressing mechanisms each comprising a shoe supporting member and a cooperating sole pressing member mounted for swinging movements relatively to each other, and with treadle controlled power operated means for operating the twin mechanisms alternately, one shoe support and pressing member remaining at rest at the 5 front of the machine in a work receiving position while the other support and pressing member are swung rearwardly to apply pressure progressively to the sole of a shoe. 7

In the operation of the machine a shoe is re- 2 moved from and another shoe placed on the sta tionary support before the treadle is depressed by the operator to connect that support and pressing member to their operating means. In mounting a shoe on or removing it from the stationary 2.5 support it is the usual practice for the operator to extend one or both of his arms somewhat across the machine. If the shoe upper is of comparatively stiif and heavy material considerable effort is required to force the heel end of the upper 0 down on the heel end of the support and in this effort the operator may slip and fall more or less forwardly upon the machine. In that event there is danger of injury to the operator by having that arm which is close to the moving support and pressing member crushed between that support and member as they swing relatively to each other to apply pressure to the sole of a shoe. Furthermore, any accidental depression of the treadle for connecting the stationary support and pressing member to their operating means may result in one or both of the operators arms or hands being caught between that support and pressing member as they are swung rearwardly. It is, therefore an object of the present invention 5 to provide in such a machine means for preventing the arm or hand of an operator from being caught between the shoe supporting member and the sole pressing member as these members are moved relatively to each other to apply pressure to the sole of a shoe.

According to a feature of the invention, novel means is provided which is movable in a direction opposite to the direction of movement of the shoe support and pressing member to prevent the arm or hand of an operator from being caught between these parts during the sole pressing operation. As shown herein, this means comprises a pairof bars which extend upwardly, one on each side of the support and the pressing member, a considerable distance above the upper 0 surface of the support. Preferably and as illustrated, the bars are mounted for swinging movement about the same fulcrum as the support and means is provided which is controlled by the swinging of the sole pressing member about its fulcrum for swinging the bars about their fulcrum in a direction opposite to that of the movement of the support and pressing member. In accordance with a further feature of the invention the construction is such as to accelerate the movement of the bars past the supportand pressing member to insure the removal of the operators arm or hand from between these parts before they have been moved into position to apply pressure to the sole. In accordance with another feature there is provided means arranged to lessen the. force of the action of the bars on the arm or hand of the operator, this means, as illustrated, comprises a yielding device between the bars and their operating mews arranged to permit the bars to yield to a limited extent as they engage the arm or hand of the operator before the bars are'moved positively forward to remove the operators arm or hand from between the shoe support and the sole pressing member.

A further feature of the invention consists in novel means that may be utilized, as an alternative, for stoppingthe operation of the machine if the arm or hand of an operator is in position to be caught between the shoe support and the sole pressing member as they are moved to apply pressure to the sole, the construction shown comprising a two-part lever for supporting the abovementioned bars, the parts of the lever being mounted for relative swinging movement to connect the bars and their operating means to means for stopping the operation of the machine when the forward movement of the bars is obstructed by the arm or hand of, an operator.

The above and other features of the invention including various. novel details of construction and combinations of parts will now be more particularly set forth by reference to the accompanying drawings and will be pointed out in the claims.

In the drawings,

Fig. 5 is a View in front elevation of the parts shown in Fig. 4.

The machine herein shown, like the "machine of the Letters Patent mentioned, is provided with duplicate sets of shoe supports and pressing.

members, each set comprising a last carrier or jack and a'cooperating sole pressing form, each set being operated independently of the "other to apply leveling pressure progressively to the sole of a shoe. The jacks-and forms are mounted to operate as in the machine of said Letters Patent with the exception that the axis about which the forms oscillate is located to the rear of the axis about which the jacks oscillate, instead of being located in the same vertical plane with said axis. Only one set of jacks and forms is shown in detail or need be referred to for an understanding of the present invention.

As shown in Figs; 1 and 2 each jack is pivotally mounted upon a transversely extending shaft 12 mounted in suitable bearings carried by the frame 14 of the machine. Each jack is'connected by a link 16 to a carrier 1'7 for a sole- .pressing form 18 which carrier ispivoted at 20 to the frame 14. The jacks are connected by links 22 to treadle-controlled power-operated means in the same manner as in the machine of the Letters Patent above referred to. The means for imparting operative movement to each jack and form is not shown herein but is fully illustrated and described in said LettersPatent. It will be understood that a shoe is mounted on a last 21 on the jack 10 by the operator when 'the jack is in its outermost position and that, in the operation of the machine, the jack and its cooperating sole-pressing .form are swung inwardly or rearwardly away from the operator to apply rolling pressure to the sole, after which the jack and form are brought to rest with the jack in its outermost position to permit a shoe to be removed from the jack and another shoe placed thereon.

Threaded into the outer end of the shaft 12 and concentric with the axisthereof isashouldered stud 24 upon which there ispivotally mounted a bracket 26 provided with a forked upper end to the arms 28 of which there are secured rods or-bars 30 which extend upwardly,one on each side of and close to thejack 10. Means are provided which will presently be "described for swinging the bracket 26 and the bars 30 forwardly as the jack and its cooperating form are swung rearwardly to apply pressure progressively to the "sole of a shoe mounted on the jack. As shown, the bars 30 extend upwardly a considerable distance above the upper surface of the last 21 so that in their forward swinging movement they engage andpush forwardly the hand-or arm of the op erator if it is in such a position that it would be caught between the bottom of the shoe on the jack l0 and the form 18 as the jack and form come together during their rearward swinging movement. of the bars 30 is accelerated in order to insure removal of the operators arm or hand from between the jack and form before the jack and form are moved rearwardly into position to apply pressure to thesoleas will behereinaiterdescribed.

Pivotally connected aty32 to the bracket 26 is a rod 34, the upper end of which is pivotally connected to one arm 36 of a bell-crank lever 38 pivoted at 40 to a bracket 42 secured to the frame 14 of the machine. The bell-crank lever 38 is provided with an upwardly and rearwardly extending arm 44 the upper surface of which is formed asa cam 46. The lever 38 is urged in a counter-clockwise direction as viewed in Fig. 1 by a spring 48, one end of which is connected to the arm 36 and "the other end of which is connected to "the frame 14. Movement of the lever 33 under the influence of the spring 48 is limited by engagement of the cam 46 with a roll 50 which is carried "by the pivoted sole pressing form carrier 17, the'construction being such that asthe solepressing 'form 18 is swung downwardly and rearwardly'from its fully forward position, the bellcrank lever 38 is swung in a clockwise direction as viewed in Fig. 1 and through the rod '34 and bracket 26, the bars 30 are swung in a counterclockwise direction from a position rearwardly of the jack -10 forwardly toward the operator. The

lever 38 is partially enclosed by a'cover 52 se-- cured to the frame 14, the upperportio'n of which is cut away to permit the roll 50 to engage the cam 46. The configuration of the cam 46 is such that the forwardly swinging bars 30 are moved at a greater rate of speed than the rearwardlyswinging jack and form so that the bars 30 will be forward of the bite where the shoe bottom and form meet before the shoe bottom and form engage each other. Thus any part ofthe operators arms or hands which maybe in positionto be injured by being caught between the shoe bottom and the form will be forcibly removed by the forwardly swinging bars '30be'iore the sole pressing form 18 engages the shoe bottom. The upper ends of the bars 30 are bent forwardly as shown so-that if the sleeve of the operators coat,

for example, catches on one of thebars, the bar,

as it swings rearwardly, will release the sleeve and not-drag it and the operators arm back into As shownparticularly in Figs. 1

bent somewhat rearwardlyfrom its lower end and. 'tlnan forwardly, as shown in Fig. '1, so as to pro Preferably the forward movement vide more clearance for the left arm oftheoper- 'at or'while he is removing a shoe fromor placing a shoe on the right-hand last. In placing a down on'the la'stby placing'his lefthand around "-the heel endand partly on: the tread surface of the shoe In mountinga shoe on the right hand "jack, the operat'ors left 'arm naturally comes close to the swinging .jack and form on the "left and, accordingly, the inner bar of the left-hand pair is shaped as above described so as not to interfere unduly withthe operation of placing a shoe on the right-hand last. The shape of this bar, though bent, is such that it will prevent the operators left arm from being caught between the left-hand last and form.

For permitting the bars 30 to yield to a limited extent in their forward movement after they engage the arm or hand of the operator there may be provided a yielding device for connecting the bars 30 and their operating means.

As shown in Fig. 3, instead of the rod 34 there may be provided a rod formed in two parts connected by a sleeve 54 which is secured to the lower portion 56 of the rod and is provided with a pin 58 which extends through a lengthwise slot 60 formed in the lower end of the upper portion 62 of the rod. Between the ends of the lower and upper portions of the rod there is mounted in the sleeve a spring 64 which is arranged to yield when the forward movement of the bars 30 is obstructed and this yielding movement is limited by engagement of a collar 66 secured to the upper portion 62 with the upper end of the sleeve 54. The slot 60 is of sufiicient length to permit the spring 64 to yield until the collar 66 engages the upper end of the sleeve 54 after which the bars 30 are moved positively forward to remove the arm or hand of the operator from between the jack and form.

The illustrated machine like the machine of the Letters Patent previously mentioned is provided with mechanism under the control of the operator for disconnecting the jack and form from their operating means at any point in their cycle of operation. This mechanism which is not shown or described herein in detail since it is fully shown and described in the Letters Patent hereinbefore mentioned, is controlled by a pull rod 68 (Fig. 4) which extends forwardly into a. convenient position to be grasped'by the hand of an operator and forward movement of which is operative to throw the operating mechanism of whichever jack and form are being operated out of operation.

The illustrated machine may be provided with means for connecting the operating means for the bars 30 to the pull rod 68 to stop the operation of the machine when the forward movement of the bars 30 is obstructed by the arm or hand of an operator. As shown in Figs. 4 and 5 there is provided a two-part lever 70, the parts of which are mounted for relative swinging movement, for supporting the bars 30. The lower portion 72 of the two-part lever is pivotally mounted on the shouldered stud 24 and has pivotally connected to it at 74 an upper portion 76 to which the bars 30 are secured and which is normally held against a stop '78 formed on the lower portion 72 by meanslof a spring 80. The lower portion 72 has pivotally connected to it a rod 34 which is preferably a solid rod as shown in Fig. 1. The upper portion 76 of the two-part lever is provided with a downwardly extending arm 82 provided with ratchet teeth 84 which are arranged to engage, upon relative movement of the upper and lower portions of thetwo-part lever 70, ratchet teeth 86 formed on a segment lever 88 which is pivotally mounted on the shaft 12 and is connected to the pull rod 68 by a link 90. From the above description it will be seen that as the bars 30 in their forward movement are obstructed by the arm or hand of the operator relative movement between the upper and lower portions of the two-part lever '70 is permitted, by reason of the yielding of the spring 30, until the ratchet teeth 84 engage the ratchet teeth 86 formed on the lever 88, after which as the two-part lever is moved forwardly the pull rod 68 is also moved forwardly to stop the operation of the machine. It will be seen also that any forward movement of the bars 30 after the ratchet teeth have become engaged and before the machine is stopped is in a direction to move the arm or hand of the operator, which is in the path of the forward movement of the bars, away from the jack and form. Removal of thearm or hand of the operator permits the spring 30 to disengage the ratchet teeth 84, 86 after which the machine resumes its operation. The mechanism above described for connecting the bars 30 to the pull rod 68 is substantially the same for each jack and form, there being two rearwardly extending links 90 connected to the pull rod 63.
