CONTROLLING DEVICE FOR USE IN SHEET-FEEDING AND LIKE MACHINES.
Specification of Letters Patent.
Patented Nov. 16, 1915.
Application filed June 24, 1915. Serial No. 36,142.
ployed, for instance, to supply a high-speed press having an automatic sheet registering mechanism it frequently happens that the feed of the individual sheets must be suddenly interrupted. In such a case it is desirable that the high speed press as well as certain moving parts of the sheet registering and sheet feeding mechanisms are not disturbed from and allowed to continue their regular motion. On the contrary, these'devices should be capable of continuing their movement and of remaining ready for immediate use at their normal speed as soon as they are thrown into action.
The object of this invention isto prevent the injury to or breakage of such moving parts due to their sudden stoppage and the delay which must necessarily result if such parts, after being stopped, have first to attain their normal speed.
Now, this invention has for its object to control the chief moving parts in the sheet feeding mechanism, viz the combing device and the roller supplying the bank of sheets to the same, so that the actual feeding operation of these parts may temporarily be stopped at will without preventing them from continuing the movement which they derive from the driving means.
To this end according to'the present invention, the lever which serves in a known manner to automatically raise the combingv wheels of the sheet feeding mechanism is connected to a manually operated device which is also employed to control the sheet feeding roller. By the. actuation of the said device the operation of the combing wheels, the sheet feeding roller and the sheet brake are simultaneously interrupted for any desired period of time. i
The invention is illustrated by way of example in the accompanying drawings, in which Figure 1 is a lateral elevation of the principal parts of a sheet feeding machine provided with the controlling device. Fig. 2 shows some of the parts indicated inFig. 1 p
in the position which they assume during the action of the controlling device, certain other parts being omitted for the sake of clearness, and Fig- 3 is atop plan view of Fig. 1.
Secured to an operation shaft 2 is a hand lever 1. The same shaft also carries a cam 4 which serves to raise the combing wheel 3 by depressing an arm 5 arranged on the shaft 6 which as usual carries also the lever 8 which is adapted'to cooperate with the carrier 7 of the combing wheel 3 in a well known manner, This carrier 7 is constructed in the form of a housing containing the driving gear for the combing wheel. Mounted on the shaft 2, moreover, is a toothed segment 9 meshing with a corresponding segment 10 on a shaft 11. Secured to the shaft 11 is an arc-shaped cam 12 so as to move with-the segment 10 in which movement the cam 12 cotiperates with a cam 13 which is rotatably arranged on the shaft 2. These two cams are adapted to lock the lever arm 5 in the position to which ithas been depressed by the cam 4 as indicated in Fig. 2. The cam 13 also serves to control the operation of the driving mechanism for the sheet feeding roller 32.
When in the position shown in Fig. 2 the cam 13 bears, by means of its recessed rear end, against a pin 27 on a rocking arm 28 which, by means of a hub 15, is loosely rotatable on the shaft 2. By means of a connecting rod 34 the-rocking arm 28. is connected 'in a well known manner to the rocking arm 35 which carries the ratchet pawl 36 actuating, by means of the usual ratchet wheel and through the agency of the toothed Wheels 37 and 38, the sheet feeding roller 32 in an intermittent manner. The member fordriving the mechanism shown in the present case is a crank disk 23 to the crank pin 30 of which is attached a connecting rod 29, the free end of which is provided with a slot embracing a pin 40 secured on the rocking arm 28. According to the position of the pin 40 within the slot in the connecting rod 29 the rocking arm 28 is moved by the connecting, rod 29 to a greater or smaller extent and this movement is transmitted by the connecting rod 34 to the rocking lever 35 and, consequently,,to the feeding roller 32. Now, by the cam 13 above referred to the rocking arm 28-may be moved to such a position as to prevent any movement from" being imparted to it by the connecting rod 29 or only a movement so slight as to be insuflicient for the pawl 36 to engage "a new tooth of its ratchet wheeL. In this case the usual spring 31.can likewise no longer retract the connecting rod 34: and, accordingly, the ratchet gear cannot perform any feed action. While, however, by raising the combing wheel 3 with the aid of the hand lever 1 the feed of sheets from the pile feeding roller by the combing device is interrupted a certain amount of feed would still be' possible as the usual sheet brake l8 continues to perform its movement on the bank of sheets 26 In order to prevent this also an .arm '14: is secured to the shaft 2 and has its free end attached to a connecting rod 16, the other end of which is connected to the guide rails 17 which support the carriage 20 upon which the sheet brake is mounted. The rails 17fare connected to two rocking levers 19 to which a swinging movement is imparted from a cam 22 by a connecting link-25, of which one end is guided on'the cam by means of a roller 24. By rotating the hand lever 1 into the position shown in Fig." 2 the rails 17 are raised by the arm 14 and, accordingly, the brake 18 is moved out of the path of the sheets while the transmission of movement thereto from the cam 22 is interrupted by the roller '24 being thrown out of engagement thereing wheels, a hand operated lever controlling the combing wheels, and cams actuated by the movement of said hand operated lever whereby the supply roller and the sheet brake are simultaneously interrupted when the combing. wheels are raised from the sheets.
2. A controlling device for use in sheet feeding and like machines comprising a brake support so as to move the brake out of contact with the bank of sheets.
3. In a controlling device for use in sheet feeding and like machines, a sheet feeding roller, a rocking arm transmitting movement to the roller, .a controlling shaft, a toothed segmentthereon, a second toothed segment meshing therewith, a cam actuated by the second segment, and a locking cam on the controlling shaft cooperatingwith the cam actuated by the second segment.
4. In sheet feeding and like machines, a hand operated controlling device adapted to temporarily interrupt the operation of the combing wheels, the sheet feeding roller and the sheet brake simultaneously comprising a separate shaft, a hand operated lever thereon, and means in connection therewith for temporarily interrupting the operation of the active parts named. i
