In the ends of the cylinder 40 are placed the cylindrical pistons 48 and 49, and the cylinder provided with two sets of induction and eductionorts 50, 50, 51, 51 one set at each end, to w rich ports are connected pipes for carrying the motive-fluid to and from each end of the cylinder.
While but a single cylinder is shown for the reception of the istons it is obvious that other means may e employed to receive them, the two compartments constituting in effect independent cylinders, although joined in the present instance.
The cylinder 40 is closed at each outer end 10 and open at the inner portions 4()'----40'- leading into the opening -tl. on the inside are the recesses 50", 51 with which the ports 50 and 51 communicate, and which recesses lead from these ports to the opening all.
On the protruding end 39 of the stem 22 is secured a collar 52 having the flanges 53 and groove 54. Near this collar 52 is located in bearing 55 a guide-rod 56 having the feather 57. Sleeved 011 this guide-rod 56 and secured from rotation is a spool 58 having the heads 59, 59. sleeved is a barrel GO'having a curved finger 61 which fits within the groove 54 of the collar 52 and a depending lug 62. The length of the barrel 69 is less than the distance between the heads 59, 59 of the spool 57, there being a space 63 as shown in Fig. 4. On the guide-rod 56-is fastened an adjustable limiting stop 64. Extending from the head 59 of the spool is an eye 65 in whicn by double nuts 66 is held the end (37 of a pistonrod (in extending from a piston head (59 within a cylinder 79 secured to the machineframe in convenient juxtaposition lo the spool 58. The cylinder 70 is provided with orts 71, 72, one on each side of the piston mad ()9, to which the pipes for the motivefluid are connected.
Located near the spool '58 and substantially in line with the cylinder 70 is a frame 73 provided with the supports 74, 7-1 in which is loosel held a rod 75 to which is rigidly but ad ustably attached a dog 76. In the frame 73 is formed the cylinder 77 in which is located the piston-valve 78, having the head 79 and stem 80. Around the stem 89 is a spiral spring 81 which bears between thehead 79 and an end bearing 82. The piston-head 79 has two circumferential grooves 83, .84, and at its end 85 a notch 86, opening outside of the open end of the cylindcr 77. At this end the cylinder frame has a rabbet 87 over which projects the outer end 88 of a spring-actuated plunger 89, which is located in a recess in the support 74. Projecting out from the frame 73 at this end are cars 90 in which is pivoted an anglelever 91, the upper end 92 of which rests in a At the ports On this spool loosely notch 93 in the end of the rod 75, and the lower end or heel 94 of which is turned in under the lower end of the plunger 89 and alined WiillLthG notch 86 of the piston-head 79. Communicating with the interior of the cylinder 77 at the piston-head 79 are the induction and *cduction ports 95 96 for the motive-fluid and the, eduction-port '97 connected with a whistle or other signal or alarm 98,the position of the ports being properly located in relation to the grooves 83, 84. The piston-head also has a recess 79 communicating with the groove 84, but not with the groove 83.
Leading to the induction-port 95 of the cylinder 7 7 is a motive-fluid supply-pipe. 100, and connected with the eduction-pipe 96 of the cylinder 77 is a pipe 101 which is connected with the induction-port 50 of the cylinder 10, while. a pipe 10?. connects the eductiou-port. 50 of the cylinder 10 with the port '71 of the cylinder 70.
Leading to the imluction-port 5] of the cylinder to is a motive-fluid supply pipe 193, and connected with the educt-ion-port 51 of the cylinder 40 is a pipe 104 which is connected with the port 7'. of the cylinder 70.
With the various parts in the position shown in the drawings the stock is at its extreme forward movement, and the clutchactuator 10 is binding the chuck 18 against the stock, holding it firmly for the operation to be had upon it.
'lhe'motive-iluid is admitted through the pipe 193 and induction-port .51 to the cylindcr 40, passes out through the eductionport 51 through the pipe 104, and through the port 72 of the cylinder 70, and moves the piston-head (59. The fluid in the cylinder 7() in front of the piston-head (59 is forced through the port 71, pipe 102, port 59 and recess 50 out through the opening 41 in the cylinder 49. The pressure upon the piston-head 69, through the piston-rod 68., moves the spool 58 which carries the secondary sleeve 60 and through the arm 61 acts upon the rear of the primary sleeve 2:2 retracting it along the stock aml with it the feed-grip to a position where it is ready to mow the stock forward. ism not necessary to be shown the motiveiluid is now cut oil from the pipe 193. aml supplied to the pipe 100, passes through said pipe 109 and induction port- 95 to the cylindcr 77, (the piston-valve 78 being in the normal position shown in Fig. 4) and hrou'gh the groove 83. pipe 191 and cduction-port 50 into the cylinder -19 back of the piston The prissurc now moves the piston 18 for ward and through the arm 46 and yoke 38 slides the collar 34 forward releasing the levers 29. The spring-plungers 21 force the chuck-actuator 10 from off the chuck 17 releasing the grip of the latter upon the stock, the conical end-13 of the head 11 By valve-mcchanpassing between the levers 29 and by the shoulders 32 of said levers. As soon as'the piston 48 has made its'traverse accomplishmgthe result thus described the'mo'ti vefluid passes through the port 50, through the pipe 102 and port 71 into the cylinder 70 behind the piston-head ,69 causing it to move backward and through mechanism already described, causing the feed-grip 22 to move the stock forward another space. As the piston-head 69 moves away from the port 71 the air in front of the piston is exhausted th ough the port 72, pipe 104, port 51, an( recess 51 out through the opening 410i the cylinder 40. i
As soon as the stock is in its forward or operative position, the motive-fluid is cut oil from pipe 100 by a valve (not shown) which opens an exhaust to the atmosphere, and is ticn admitted through pipe 103. and induction port 51 to act upon the fluid-piston 49,
moving said ston to the p'osition'shown in Fig. 3, and e, levers 29 are forced toward each other, the shoulders 32 moving on the conical end 12 of head 13, and advancing the sleeve and chuck actuator 10 to close the chuck 17, thus causing the chuck to grip the stock and hold it for operation. As the motive-fluid operates the piston 49, the fluid back of thepiston 48 exhausts through the port 50, pipelOl, ports 96 and 95, and pipe 100 to tie atmosphere through the valve above mentioned. .Further' operations con- .tinue as already described.
In the operation of the device should the stock become exhausted and the sleeve 22' be empty when retracted, the momentum of the secondary sleeve would overcome its friction'upon the spool 58 and said sleeve will move up against the head 59 on spool 58. Now the lug 62 and adjusted tappet 76 are so spaced apart that under normal positions when there is stock in the machine the drag of the feed-grip on said stockkeeps the secondary sleeve 60 from sliding on the spool 58 and the lug 62 from striking the tappet 76, but should the sleeve 22" be empty and the secondary sleeve 60 slide on said spool 58, the lug'62 .will strike the tap et 76, causing the rod 75' to be actuated; I his .causes the an-,
le-lever 91 to turn on its ivot and force its ower end 94*into linewitrthe notch 86 of the piston-valve 7 8', and the spring 81 then presses said valve 78inwardly until theeduction-port 96 is closed and the end of the recess 79 of the valve covers the inductionport 95 in the cylinder. The motive-fluid supply isvthus cut off to the cylinder 77 and the cylinders 40 and 70, the exhaust-fluid passing through the recess 79 groove 84, port 97, and whistle 98, as indicated in Fig. 5, and sounding an alarm during each rotation of the spindle; To restore the piston 78-to normal osition, it is pushed back by hand UP again locked by the angle-lever 91.
of alarms may be substituted there-for without departure from the invention.
