ROTARY SWITCH.

SPECIFICATION forming part of Letters Patent No. 761,769, dated J une 7, 1904. Application filed March 4:, 1898. Renewed October 3, 1203. Serial No. 175,697. (No model.)

To aZZ whom it may concern: I

Be it known that I, ROBERT T. JOHNSTON, a

citizen of the United States, residing at Plainfield, in the county of Union and State of New Jersey, have invented a new and'useful Rotary Switch, of which the following is a speci-" fication.

v The aim of this invention is to improve the" switch. I Fig. 4 is an end elevation of part of the mechanism; and Figs. 5, 6, and 7 are diagrammatic views illustrating the action of my improved switch. 1

I will now describe the delivery mechanism shown in the drawings and in such description will be contained a description of my improved switch.

The operative parts hereinafter described may be mounted in any suitable framing, as A. F represents aformer over which a web or webs may be folded.

. IO-and 11 are the ordinary rolls used at-the nose of the former, and 12 and 13 are the drawing rolls or cylinders, which act to draw the web or webs over the former. tween the rolls 12 and 13 the folded web or webs is or are led by means of tapes (0 to-the cutting-cylinders 14: and 15, the tapes aturning down over the tape-roll 17 and the web or webs being guided to the cutting mechanism by means of suitable guide fingers 160. These cutting-cylinders .14 and 15 are preferably arranged to cleanly sever the web into sheets. From these cutting cylinders the sheets will pass down between the tapes I) and the guides 18 to a collecting-cylinder 20. The

From betapes 6 are led around the tape-

rolls

16, 25,

and 26, as shown, so as to embrace a portion of the periphery of the collecting-cylinder 20. Also bearing on the surface of the collectingcylinder 20 are the tapes 0, which are led around the tape-

rolls

21 and 22, as shown.

Guides 24 are arranged as shown, and the ends 240 of the guides form the entrance or meeting point of two pathways, one pathway being up around the collecting-cylinder 20 between the same and the tapes 0 and the guidin'g ends 180 of the guides 18, again between the collecting-cylinder 20 and the tapes 5, and the other pathway being away from the collecting-cylinder 20 between the said guides 2A and the tapes 6. Thesheets from the collooting-cylinder will normally pass into the pathway between the tapes 6 and the guides 24:, and to control the entrance of the sheets into the other pathway I use my improved switching mechanism, which I will hereinafter term the rotary switching mechanism S. The sheets, collected or otherwise, as they pass from the collecting-cylinder willrun out on the tapes I), down over guides 260, against a suitable stop 27. The tapes (0 are turned over the tape-rolls 23 to assist in carrying the sheets down on these guides 260. When the sheets reach the stop 27 a rotary tucker or folder T of the usual pattern will tuck or fold the sheets between the folding-rollers 28 and 29, and from these rollers the folded sheets will, be led, by means of the tapes a and d, to the delivery mechanism. The tapes (6 are turned up'over the folding-roller 28. From the folding-rollers 28 and 29 the tapes a and (Z are led over the guiding rolls or cylinders 30 and 31 to the cylinder or turning-roll 32. From the cylinder 32 the tapes a are led, by

means of tape-rollers 33, 34, and 35, back to stripped from the tapes by means of fly-fingers 39, mounted on the shaft 40, which shaft 40 is oscillated by means of a pitman 41, connected to a wrist-pin carried by the shaft of the cylinder 32, which pitman connects by crank 42 to said shaft 40. This mechanism will deliver the sheets onto the delivery-tapes 43, which are led around the rollers 44, 45, and 46, as shown, and these delivery-tapes are jogged or slowly moved by any of the usual mechanisms for this purpose to slowly deliver the folded products.

It will be seen that the fixed guides 38 and the tapes 43 form a wedging-pathway into the apeX of which the head of the rapidlymoving folded sheet is run. This will nicely and easily arrest the movement of the sheet, and just as this action takes place the fly-fingers 39 will knock the sheet down clear of the tapes (Z and the fixed guides 38.

The rotary switch, which is the especial feature of my invention, consists of a shaft 50, mounted in suitable brackets in the framing A, and on this shaft 50 are mounted arms 51, which arms are counterweighted, as at 52. A shaft 54 is arranged between these arms, as shown, and mounted on this shaft are a number of curved guide or switch fingers 55, which will intermesh with the projecting ends 240 of the guides 24. This shaft 54 has on the end thereof a crank or bracket 56, and a screw 57 is passed through the same and tapped into one of the arms 51, whereby by removing the screw and turning the arm the switch-fingers can be turned down toward the shaft 50 into an inoperative position, as shown in Fig. 3. The action of this rotary switch mechanism is as follows: By the gearing hereinafter described the rotary switch will make one turn for every two turns of the collecting-cylinder 20. It will be seen that from the point of the guide-fingers 24, as before specified, there is provided a long and short pathway for the sheetsthat is, the long pathway will include a travel around the collecting-cylinder. It also will be seen that the sheets will normally pass from the collectingcylinder out on the tapes 7); but every alternate sheet will be taken by the fingers 55 of the rotary switch and the leading edge thereof lifted to come into the bite of the tapes C upon the collecting-cylinder 20. This will cause every alternate sheet to pass around the collecting-cylinder and to associate with the next succeeding sheet. This action is shown clearly in the diagrammatic figures on the third sheet of the drawings. This switching mechanism is a very desirable mechanism for this purpose. The ordinary switch used for this purpose is eam-actuated and will rapidly and quickly wear itself out, while, on the other hand, a mechanism which continually rotates has no jars or shock imparted thereto and to get the operation before described.

does not depend on the accuracy of a cam or cams for its nieety of operation. l urther, a part which is rotary in action as compared with a part which oscillates or reciproeates has great speed, and speed is the desired object of all sheet-delivery mechanisms. It will be seen that the switch-lingers when adjusted to their operative position are rigidly connected to the shaft 50 or to the axle of the switch and that their action is dependent merely and only upon the rotation thereof, whereby cams, eccentrics, and other devices to operate said lingers are dispensed with. This construction provides a device which is very easy of manufacture, simple in its parts, of long life, and accurate in operation.

In the especial organization shown the cutting-eylinders will cut the sheets cleanly from the web, and these sheets will be associated as before described. This can be done without the use of accelerating-tapes, grippers, or pins and without tearing or leaving teats on the sheets, thus producing a very high-grade product.

By rendering the rotary switch inoperative, as before described, sheets can pass from the cutting-cylinders directly to the rotary folder, and thus either a single or associated product can be delivered. The rotary switch can also be rendered inoperative by disconnecting the gear on the shaft thereof from connection to said shaft by any of the usual key or clutch mechanisms, so that the rotary switch will not turn as the remaining parts of the mechanism are operated. \V hen this arrangement is used, the switch-lingers are left in a position clear of the collectiiig-eylinder when not in use. Although I have shown this rotary switch as used in connection with a collecting-cylinder, it is obvious, of course, that the same may be used to direct sheets into different pathways even if such pathways do not comprehend a collecting-cylinder.

The gearing for driving the parts may be of any of the ordinary forms, and the way .1 arrange the same in the device shown in the drawings is as follows: 501 designates a powershaft which carries a pinion 502, which meshes with a gear 500 on the shaft 50 of the rotary switch. The gear 500 meshes with a gear 200 on the collecting-cylinder, and the proportion in this particular device is two to one, so as The gear 200, by means of a suitable intermediate 201, drives the gears 150 and 141) of the cutting-cylinders. The d rawing-cylinders l2 and 13 are driven from the gear 141) by means of intermediate 142 and gears 120 and 13d. 3y means of gears 850, 351, and 321) the turning cylinder 32 may be driven from the gear 124). By means of gears 503 and 504 the rotary tucker is driven. By means of further gearing, as shown, which is not necessary to depinion t, which engages with an internal gear t, so that the tucker-blade will act in the ordinary manner to tuck or fold the sheets into the bite of the folding-rolls 28 and 29.

The details and arrangements herein described maybe greatly varied by a skilled mechanic without departing from the scope of my invention as expressed in the claims.
