-J ingly illustrated in its application to a machine constructed especially for that purpose. lt will be recognized, however, that in various novel aspects the invention is not limited to machines for operatin y upon turn shoes Or to means for shaping that particular portion of the sole.

In order to shape or level satisfactorily the sole of a tui-n shoe, it is necessary to subject the sole to such treatment as to flatten the seam whereby the upper is secured to the sole,

to remove irregularities which are likely to be especially prominent in the shank portion of the sole, and in general to conform the n, sole to the transverse curvature of the bottom oi the last which is especially pronounced also at the shank. At the same time, it is necessary to guard against undue stretching in the direction of its length or otherwise distorting or injuring the single sole with which this type of shoe is provided, as might result, for example, from the use oi' heavy rolling pressure such as it is customary to use in leveling welt shoes.

ln view of these considerations, it has been found that in leveling the sole of a turn shoe,

' pulses to the bottom of a shoe and means for supporting and controlling the shoe to present it in such relation to the pressure-applying or leveling tool as to secure the desired results. The machine herein shown as an illustrative embodiment of the various features of the invention comprises a shoe support or jack which may be moved by power at the will of the operator in directions lengthwise of a shoe thereon to cause the tool to traverse the bottom .tot the shoe and by the use oi' which the shoe may also be tipped or inclined laterally as desired to vary its relation to the tool, in combination with a power-operated leveling tool which is reciprocated heightwise of the shoe to deliver repeated blows upon the shoe bottom under such control that its operation may be started and stopped at the will of the operator in-v dependently of the movement of the shoe support. The operator is thus enabled readily to determine and vary the position of the shoe in relation to the leveling tool and to cause dilierent portions of the shoe bottom to be subjected to varying amounts of pounding treatment as conditions may render desirable. v

Vhile in some of its aspects the invention is not limited in respect to thecharacter of the leveling tool, it is for some reasons considered preferable to use a roll so mounted as to permit it to turn about an axis extending laterally of the shoe in response to engagement of the shoe therewith. Among other advantages, this serves to avoid undue strain on the sole inthe direction of its length, such as might result from rubbing pressure, especially in operating upon the.

upwardly sloping portion of the sole at the rear of the ball-line where, in shoes having high-arched Shanks, the direction of the beating movement of the tool is at a substantial inclination to the length of the sole.

For the particular purpose of operatingV upon the comparatively narrow shank portion of a sole having a pronounced lateral curva-ture, as in a turn shoe, the roll illustrated is further provided with a V-shaped recess extending about its periphery, to adapt it to accentuate the pressure upon the opl posite side portions of the shank to assist in producing a close edge effect. It will be understood, however, that if desired a tool or roll of a different shape may be utilized, for examplesuch as to adapt it to be used upon both the forepart and the shank portions of the shoe bottom.

After the bottom of a shoe has been subjected to repeated pressure impulses or blows as above described, it is usually desirable to supplement this operation by the use of rolling pressure, in order further to insure that the sole will present a smooth and even appearance. In accordance with a further feature of .the invention, the machine herein shown is accordingly so constructed as to adapt the leveling roll to be used in both these different ways. For the purpose in view, there is provided means for controlling the reciprocatory movements of the roll in such manner as to bring the roll to a stop in pressure-applying relation to the shoe, whereupon the shoe may be subjected to rolling pressure by movement of the jack relatively to the roll. It will be evident that, with this means of control, the machine may, if desired, be used only to apply rolling pressure to a shoe. In order to permit the removal of the shoe, the machine is also adapted to bring A" the roll to a stop at the limit of its movement away from the shoe bottom, the controlling means being so constructed as to insure that it will come to a stop only at one or the other of its limits of movement toward and from the shoe bottom while enabling the operator to cause it tocome to a stop selectively in either of these positions.

In accordance with a further feature of the invention, there is provided a support for the leveling tool or roll kso mounted as to permit it to turn about an axis extending heightwise o-f the shoe, the construction shown including also spring means for normally centralizing the tool with respect to such turning movement. In operating immediately at the rear of the ball-line of the shoe the tool is thus permitted to adjust itself to the lateral contour of the shoe bottom with its axis in substantially parallel relation to the ballif line, while in operating on other portions of the shoe it is maintained in the position best adapted for use thereon.

Another feature of the invention comprises novel means` for .controlling the movements of the shoe support or jack. As herein illustrated, a single manual means is provided for controlling the power means whereby the Shoe support is moved in directions lengthwise of the shoe and for also tipping the shoe laterally at the will of the operator, the construction shown comprising for this purpose a controlling device carried by the shoe support and provided with a pair of handles whereby the operator is enabled to use both hands to controlV the dierent movements. By the use of such means the control of the shoe to present it at diHerent times in the desired relation to the leveling tool is greatly facilitated.

For controlling the reciprocatory movements of the leveling tool, the machine is provided with a manually operated clutch-controlling` member or treadle which is moved in one direction to start the tool in operation and in the opposite direction to bring it to a stop. In order to relieve the operator of the necessity of holding this member in the starting position until it is desired to bring the tool to a stop, there is further provided a device adapted to be utilized if desired to hold the member in starting position, the construction shown comprising a lock for the treadle with means enabling the operator to unlock or release it at will.

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

rIhe shoe support or jack is in many respects similar to the construction disclosed in United States Letters Patent No. 1,004,155, granted on September 26, 1911, upon an application of A. Eppler. It comprises a casting 13 pivotally mounted at 14: on the frame 16 of the machine for swinging movements lengthwise of a shoe on the jack, this casting having upwardly extending front and

rear arms

18 and 20 between which there is suspended on pivot studs 22 and 2l a shoe holder 26 havinO thereon means for supporting a shoe and its last, the supporting means comprising a last pin 28 and a toe rest 30. The last pin 28 is supported on a tipping block 32 which is pivoted at 341 (Fig. 12) on a heel post 36. 1n the construction herein shown the tipping block 32 is engaged by a spring plunger 38 which tends to swing the last pin in a direction away from the toe rest 30, and manually operated means is provioed for swinging the last pin in the opposite direction to clamp the shoe firmly down upon the toe rest. his means comprises hand lever 40 mounted on a shaft e2 which is rotatable in the heel post 36, this shaft having fast thereon a spiral gear 14 engaging a spiral gear 46 which is internally threaded for engagement with threads on a vertically movable rod 48. rl`he upper end of the rod a8 is in contact with a vertically movable plunger '-19 bearing on the tipping block 82 at the opposite side of its axis from the spring plunger 38. rlhrough these connections the tipping block is operated to clamp the shoe on the toe rest after the shoe has been mounted on the last pin 28. The hand lever 410 is so mounted that it may be moved lengthwise of the shaft l12 against the resistance of a spring 50 (Fig. 5) in its hub portion and may then be turned to bring a pin 52 thereon into position to enter any one of a series of holes 511 formed in a iiange 55 fast on the shaft 42, so that the lever may be connected to tl e shaft in different positions. 1t will be understood that the spiral gears 44E, L16 automatically maintain the parts in any position to which they are moved in acketing a shoe.

The toe rest 30 is adjustable along a guideway formed on a lever arm 56 which is pivoted at 58 on the shoe holder 26, the adjustment being eiiected by rack and pinion mechanism controlled by a hand-wheel 60. Ad-

ustment of the toe rest heightwise of the shoe is effected by swinging trie lever arm 56 about its pivot 58 throun` 1 connections including a hand-wheel 62 (Fig. 2) in the same general manner as illustrated in the above-mentioned Letters Patent.

In the use of the machine the shoe support as a whole is swung about its pivot 14, to carry the shoe forwardly and rearwardly at the will of the operator, by power-operatec means generally similar to that disclosed in the above-mentioned Letters Fatent, while at the same time the shoe holder 26 may be tipped to incline the shoe laterally as desired. The means whereby these movements are effected, including the novel mechanism provided for controlling the power-effected movements of the shoe support and for tipping the shoe holder, will be more particularly hereinafter described,

For leveling the sole of the shoe there is provided a leveling tool or roll 641 which, as herein shown, is particularly adapted to opcrate upon the shank portion of the sole and is so formed that it has a substantially V-shaped peripheral recess extending around it, as ,o

illustrated in Figs. 7 and 8. Thisroll is mounted to turn and also to slide freely lengthwise of its axis on a rod 66 (Fig. 7 supported on a holder 68 which has fast therein an upwardly extending shaft 70 mounted for turning movement in a bearing formed in the front end of a roll-carrying arm i 2 pivoted at 74 on the frame of the machine for swinging movements in a vertical pla-ne about a horizontal axis located at a substantial distance beyond the toe end of the shoe. The shaft 70 is confined in its bearing by a nut 7 6, and between the holder 68 and the lower face of the arm 72 there is a ballthrust bearing 7 8 (Fig. 7). The roll 64 is thus permitted to turn about an axis extending heightwise of the shoe, so that in operating in that portion of the shank immediately at the rear of the ball-line it may adjust itself, in response to engagement of the shoe therewith, to a position in which its axis is substantially parallel to the ball-line for better conformity to the contour of the last in that location. There is further provided means for normally centralizing the roll with respect to turning movement about the axis of the shaft 70, comprising an arm 80 (Fig. 6) which is keyed to the shaft 70 and a spring 82 connected at one end to this arm and connected at its other end to a screw 8a which is clamped in a projection 86 on the arm i' 2 and is adjustable to vary the tension of the'spring.

For imparting to the leveling roll reciprocatory movements heightwise of the shoe there is provided a lever 88 (Figs. 1, 2 and 3) mounted to swing about a rod 90 on the frame of the machine and carrying a roll 92 (Fig. 3) which is engaged by a path cam 941- formed in one side of a cam wheel 96 fast on a cam shaft 98. Fivoted on a pin 100 on the lever 88 is a block 102 connected by pins 103 to the lower end of a sleeve member 104 the upper end of which is connected to a plunger 106 (Fig. 2) Vslidingly movable on a rod 108. Between the plunger 108 and a collar 110 fast on the lower end of the rod 108 is a spring 112. rod 108 is secured between two clamp members 1141 and 116 which have opposed threaded recesses for engaging screw threads on the rod and are held in clamping position by tap screws 118. The clamp member 116 is pivotally connected at 120 to an ear 122 which is secured on the roll-carrying arm .72. lt will be understood that through these connections the arm 72 is oscillated about the axis of its pivot 74, and that when the leveling roll is carried into engagement with thel shoe by downward movement of the arm, the

The upper end of the spring 112 will yield in response to continued downward movement of the operating lever 88. Nuts 124 on the rod 108 are arranged to determine and to vary the initial compression of the spring 112 by engagement with the plunger 106 and thus to deternine the amount of pressure applied to the shoe by the roll. Since adjustment of these nuts has the edect of moving the rod 108 and, therefore, of varying the position of the roll heightwise of the shoe, there is provision for a compensatino adjustment by loosening the

clamp members

114, 116 and changing their position lengthwise of the rod 108.

The cam shaft 98 is operated through a clutch under such control that the operator may start and stop the reciprocatory movements of the leveling roll at will. In the machine herein shown power is derived from an electric motor 126 (Fig. 2) which by means of a pinion 128 on the motor shaft and an idle pinion 180 drives a gear wheel 182 loosely mounted on the shaft 98. The gear wheel 182 (Fig. 3) has on one side an internal friction clutch surface 184 to adapt it to serve as a clutch member, and for engaging this clutch surface there is provided a ceoperating friction clutch member 136 which is mounted for sliding movement lengthwise of the shaft 98 and is connected to the shaft by a spline 188. The clutch member 186 moved lengthwise of the shaft 98 by a yoke member 146 fast on a rock shaft 142 which is mounted on the frame of the machine and is provided with an arm 144 the outer end of'which is pivotally connected to a sleeve member 146 slidingly movable on a rod 148. The rod 148 has fast thereon a collar la() arranged to engage the upper end of the member 146 and thus to impart swinging movement to the arm 144 to release the clutch in response to downward movement of the rod 148. rl`his rod is connected at its lower end to a treadle 152 pivoted at 154 on a bracket 156 secured to the frame of the machine. Between the lower end of the sleeve member 146 and al member 158 which serves as a connection between the rod 148 and the treadle is a spring 160 through which movement is imparted vieldingly to the arm 144 to set the clutch in response to upward movement of the member 158 when the treadle is depressed. A spring 162 is connected to the treadle to hold it normally in its idle position and to release the clutch by returning it to that position.

(lo-operating with the clutch is a brake for immediatelv stopping the reciprocatory movements of .the leveling` roll when the clutch is released. rEllis brake comprises a band 164 arranged to act frictionally on the periphery of the cam wheel 96. The opposite ends of the band are connected respectively to dierent arms of a bell-crank 166 mounted on a rock shaft 168, and secured also on this rock shaft are a pair of lever arms 170 yto which a spring 172 is connected to assist in contracting the band 164 and thus applying the brake. For releasing the brake simultaneously with the setting of the clutch in the upward movement of the treadle-operated rod 148, this rod is extended upwardly and has mounted on its upper end a. block 174 pivotally mounted between the two arms 170. It will be understood that when the clutch is released by downward movement of the rod 148, the spring 172- is permitted to act to apply the brake, this spring suppleinenting the action of the treadle spring 162. It will be understood from the foregoing description that the reciprocatory movements of the leveling roll are started when the operator depresses the treadle 152 and that these movements will continue as long as the treadle is held in its depressed position. In order to relieve the operator of the necessity of holding the treadle depresser when it is desired that the beating movements of the roll shall continue for a considerable length of time, there is provided automatic means for locking the treadle in its depressed position. By refer-ence to Figs. 4 and 4a, it will be seen that there is mounted for vertical movement in a bracket 176 on the front end of the frame of the machine a plunger 17 8 which is adjustably connected by means of a threaded rod 180 and a. pin 182 to a member 184 secured to the treadle 152. Mounted for movement in a bearing in the bracket 176 in directions at right angles to the directions of movement of the plunger 17 8 is a locking pin 186 which is arranged to be projected over the top end face of the plunger 178 when the plimger is moved far enough downwardly by depression of the treadle. The pin 186 is connected to an arm 188 fast on a rock shaft 19() to which is also connected a lever arm 192. At its lower end the arm 192 is connected to a treadle 194 which is pivoted on van arm 196 of the bracket 176. A spring` 198 acts on the arm 192 to slide the locking pin 186 over the top of the plunger 178 when the plunger is depressed far enough to permit this movement, and thus to hold the

clutch members

132, 186 in operative engagement with each other. Then it is desired to stop the beating movements of the leveling roll, the operator depresses the treadle 194 and thereby withdraws the pin 186 from over the top of theplunger 178, whereupon the spring 162 raises the treadle 152 and thereby releases the clutch and applies the brake.

After the leveling roll has been utilized to beat the sole, and thus on turn work to flatten the seam and substantially conform the sole to the transverse curvature of the last in the shank, it is usually desirable to complete the shaping or leveling operation by rolling pressure in order to insure that the sole will present a smooth and even appearance. To

or the other of its limits of movement toward and from the shoe. To this end, there is secured to the cam shaft 98 a cam 200 3) having diametrically opposite raised portions arranged to engage a roll 202 mounted on a bracket 204 which is secured to the treadle-operated rod 148. It will be evident that when either of the opposite raised portions of the cam 200 is in engagement with the roll 202, the rod 148 is necessarily held in such a position that the clutch is set and the brake released. On the other hand, when either of the raised portions of the cam passes beyond the roll 202, the rod 148 is permitted to move downwardly and thus to release the clutch and apply the brake if the treadle 152 has been released so as to permit this action to occur. If it should happen that the leveling roll is thus brought to a stop in engagement with the shoe when it is desired that it be stopped at its opposite limit of movement, or vice versa, all that the operator has to do is to depress the treadle 152 momentarily to cause the cam 200 to turn half way around, whereupon the roll will be brought to a stop in the position desired.

The power-operated means for imparting to the shoe support or jack movements in directions lengthwise of the shoe is of substantially the same construction as that disclosed in Letters Patent No. 1,004,155, hereinbefore referred to. This means comprises a leatherfaced friction drum 206 (Fig. 1) connected with the jack by mechanism hereinafter described and arranged to be engaged on its periphery at` diametrically opposite points by two friction pulleys 208 and 210 which are driven constantly in opposite directions and which are so mounted that either pulley can be moved into engagement with the drum 206. The

pulleys

208 and 210 are driven by means of a belt 212 passing over

pulleys

214 and 216 secured to the shafts of the

pulleys

208 and 210 respectively, and also passing over an idle pulley 218 and over a pulley 220 secured to a driving shaft 222. The shaft 222 carries a pinion 224 (Fig. 2) engaged by the constantly driven gear wheel 132.

To permit the driving

pulleys

208 and 210 to be moved selectively into engagement with the drum 206, these driving pulleys, together with the

pulleys

214, 216 and 218, are mounted on a frame 226 which is pivotally supported on the driving shaft 222. By swinging movement of this frameeither of the driving

pulleys

208 and 210 can be carried into engagement with the drum 206 without altering the tension of the belt 212. Y

The connections between the above-described reversible friction mechanism and the jack comprise a pinion 228 mounted to rotate with the drum 206, a gear wheel 280 engaged by the pinion 228, a crank shaft 282 (Fig. 2) to which the gear wheel 230 is secured, and a link 234 connecting a crank pin 286 carried by this shaft to the swinging jack membeil 13. It will thus be understood that rotation of the drum 206 alternately in opposite directions oscillates the shaft 282 and through the link 284 oscillates the j ack about the axis of its pivot 14 to carry the shoe on the ack folwardly and rearwardly under the leveling ro The invention provides novel means for controlling the abovedescribed reversible friction driving mechanism and for also tipping the shoe holder 26 about the axis of its A)ivots 22 and 24 through the use of a single manually operated device arranged to perform both these functions. Secured to a rock shaft 288 (Figs. 1 `and 5) carried by the jack member 13 is an arm 240 connected by a link 242 to the rocking frame 226, and also fast on the rock shaft is an arm 244 extending upwardly and connected by a link 246 to a substantially U-shaped member 248 which is slidable lengthwise of a shaft 250 mounted to turn in a bearing in the arm 18 of the jack. Fast on the shaft 250 is a depending arm 252 provided with a slot 254 in which is mounted a roll 256 carried by the adj acent upwardly eX- tending arm of the shoe holder 26. It will thus be seen that by turning movement of the shaft 250 the shoe holder 26 may be tipped to one side or the other. Secured to the shaft 250fis asleeve member 258 along which the member 248 may slide, and between the opposite ends of this sleeve member there is provided a square portion 260 (Figs. 10 and 11) on which is slidably mounted a block 262 positioned between the opposite arms of the member 248. Mounted in the opposite sides of the block 262 are handles 264 which the operator holds with his two hands. It will thus be understood that by the use of the handles 264 the block 262 may be operated to turn the shaft 250 and its sleeve 258 and thereby to tip the shoe holder 26 in either direction desired in any position of the block 262 lengthwise of the shaft 250. By the use of the same handles the operator is enabled to move the member 248 either forwardly or rearwardly lengthwise of the shaft 250 and tie sleeve 258 and thereby to operate the arm 244 in such manner as to connect either of the friction pulleys 208, 210 to the drum 206 connected to the jack, thus causing the jack to be swung in either direction desired. It will be seen that in every instance the movement of the jack thus eliected by the friction driving mechanism is in the same direction as the movement of the controlling member 248.

To guard against any overthrow o the jack, the machine is provided w'th means ot substantially the same construction as shown in Letters Patent No. 1,004,155 for throwing the friction driving mechanism out of operation at a predetermined limit of swinging movement of the jack in either' direction, by automatically moving the frame 226 in a direction to disengage from the drum 206 that one of the driving

pulleys

208, 210 which is in operation. rlhis means comprises two rolls 266 and 268 (Fig. 1) adjustably secured to the gear wheel 280 and arranged to engage an arm 270 projecting from a sleeve 27 2 which is mounted to turn on the shaft 14 about which the j ack member 13 swings, the sleeve 272 being connected to the frame 226 by yielding means comprising links 274 and 276 and springs 27 8 (Fig. 2), the constructionof which need not be described in detail in view of the disclosure in the above-mentioned Letters Patent. When the jack arrives at apredetermined point in its movement in either direction, one of the rolls 266, 268 engages the arm 270 and through the yielding connections provided moves the frame 226 in the direction to disconnect the ack from the driving means. Y

As also illustrated in the above-inentioned Letters Patent, the machine is provided with means for steadying the jack in its swinging movements and Vfor stopping its movement when it is disconnected from the driving mechanism, comprising a brake member 280 (Fig. 2) arranged to press continuously on a brake disk 282 carried by the shaft 232. The brake member 280 is mounted on a pivoted lever 284 and is pressed against the disk 282 by a spring 286 which acts on the lever 284.

The frame 226 of the reversible jack driving mechanism is further controlled by a device of substantially the same construction as that disclosed in United States Letters Patent No. 996,707, granted on July 4, 1911, upon an application of A. Eppler, which serves4 to maintain the iframe yieldingly in a predetermined position when the handles 264 are released by the operator. This device coinprises a rod 288 Fig. 1) pivotally connected to the frame 226 and ext-ending through an eye-bolt 290 on the frame of the machine, with

springs

292 and 294 at opposite sides of the eye-bolt arranged to act on the rod with a tendency to maintain the frame in a predetermined position and against the resistance of one or the other of which the frame is swung by the operator vby means of the handles "7264. These springs are adjustable by means ot nuts on the rod 288 to vary the tension oi". either of them independently of the other, and by such adjustment the frame 226 may be held normally in a position in which both the driving

pulleys

208 and 210 are out of engagement with the drum 206. Preferably, however, the device will be so adjusted. as to tend to hold the pulley210 lightly in engagement with the drum 206 so 'i al control of the frame when it is desired to suspend the swinging movement of the jack in order to subject some particular part of the sole to repeated action of the leveling tool.

In the operation of the machine, briefly summarized, the operator mounts a shoe on the jack pin 28 when the jack is in'its normal idle position and by movement of the handle 40 tips the j ack pin to clamp the shoe tirinly upon the toe rest 30. He. then gi'asps the handles 264 and by pushing forwardly thereon connects the jack to the reversible friction driving mechanism to cause it to carry the shoe forwardly under the leveling roll 64 which is at that time held at its upper limit of movement. `When the iack arrives in a position in which the roll is over Vthe shank portion of the sole, the operator depresses the trea-dle 152 to set thc clutch and release the brake and thereby cause the roll to be carried repeatedly into and out of engagement with the shoe bythe action of the cam 94 to subject the sole to a. plurality of blows. Since the roll 64 as illustrated is intended to operate only onV the shank portion of the sole, the opera-tor will control the movements of the ack by manipulation of the handles 264 in such manner as to cause this portion only of the sole to be moved forwardly and ieaiwvardly under the roll as many times as desired. At the saine time, by further manipulation of the handles 264. the operator will tip the shoe holder 26 in opposite directions as desired to canse theI beating action of the roll to be accentuated upon the opposite edge portions ot the sole and thereby to impart to the sole the desired transverse curvature with its edges pressed closely against the upper. lt will be understood that while thus controlling the lateral inclination of the shoethe operator may at any time stop the swinging movements of thejack to canse any particular portion of the sole to receive repeated blows from the leveling roll.Y At any time in the action of the roll on the shoe. and particularly when it is acting upon that portion of the sole immediately at the rear of the' ball-line, the roll may turn about the anis of the shaft 70 against the resistance of the spring 82 to adjust itself to the transverse contour of the last bottom.

ln operating as above described, theoperator may hold his t'oot upon the treadle 152 until it is desired to terminate the beating action of the roll, or alternatively he may depress the treadle tar enough to cause it to be locked by the pin 186. t the treadle is thus locked, the beating action ot the roll will be continued until the operator depresses the treadle 19d` te unloclr the treadle 152. lVhen the treadle 152 is permitted to rise in response to the action of its spring 162, the clutch is released and the brake applied in the manner hereinbetore described. By reason of the action of the cam 260 the roll can come to a stop only at its upper limit of movement or at its lower limit of movement. It is usually desirable that, after the beating action of the roll upon the sole, the latter shall be subjected to rolling pressure in order to smooth it and thereby complete the leveling action. To permit that operation the roll should be brought to a stop at its lower limit ot movement, and if it should happen that when the treadle 152 is released the roll does not come to a stop in that position, it may be returned to that position in response to a momentary depression of the treadle. `While the roll carrier 72 is then held stationary, the operator will cause the jack to be swung bach and forth by the friction driving mechanism so that the sole will receive ro ling pressure, the roll at that time being held against the shoe by the compression of the spring 112. During such rolling action the operator will further tip the shoe holder as desired. V] hen the leveling operation has been completed, the operator will again momentarily depress the treadle 152 far enough to cause the clutch to act, but not 'tar enough to cause the treadle to be locked, whereupon the cam 200 will be turned far eno-ug"L to cause the roll to be brought to a stop at its upper limit of movement. The ack-controlling mechanism will then be manipulated to cause the jaclr to be swung outwardly to its idle position, or it the operator merely releases the handles 264, the jack will thus be returned automatically in response to the controlling action of the springs 292, 29et on the frame 226.
