VALVE-CHANGING DEVICE.

Application filed February 1, 1917.

To all whom it may concern:

Be it known that I, ALBERT BROADMEYER, a subject of the Emperor of Germany, and a resident of Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented a certain new and useful Improvement in Valve-Changing Devices, of which the following is a specification.

My present invention relates generally to valve changing devices, and more particularly to adjustable means for controlling the periodical opening and closing of the air valve utilized in paper feeding machines, and in connection with paper ruling machines to which the paper is fed, my object being to provide in the first instance simple, inexpensive, and readily adjusted means, constituting an improvement upon the corresponding means as shown and described in my ,Patent Number 1,183,626, dated May 16, 1916.

In paper feeding machines, the air eX- hausting connections leading to the suction cylinders, which pick up the individual sheets of paper at the beginning of the feeding operation, are provided with valves which are automatically controlled from the paper ruling or other machine to which the paper is fed, in order that the paper may be fed in properly timed relation to the operation of the paper ruling or other machine.

My present improvements relate particularly to adjustable means adjacent the paper ruling or other machine to which the paper is fed, in order that an adjustable control of the regulating valve may be had, to operate in connection with sheets of different size and secure the desired intervals between the sheets, the adjustments providing for ready change from sheets of one size to sheets of another size.

In the accompanying drawings illustrating my present improvements:

Figure 1 is a side elevation of a portion of a ruling machine, with my improved valve controlling parts, and showing an air valve with its controlling connections, in operative relation thereto;

Fig. 2 is a plan view of a portion of the ruling machine, and my improvements attached thereto;

Fig. 3 is a side view thereof, and

Fig. 4; is a vertical section taken substantially online.4 4 of Fig. 3.

Specification of Letters Patent.

Patented June 26, 1916.

Serial No- 146,048.

Referring now to these figures, and particularly to Fig. 1, I have shown at 246 a valve such as in my patent above referred to, for controlling the air connections to the suction cylinder of a paper feeding machine, the arm .248 of which is connected by a forwardly extending rod 2&9, extending through a portion of the frame 185 of the paper ruling or other machine to which the paper to be fed, the forward extremity of this rod 249 being pivotally united at 250 to the lower end of a lever 251, having an intermediate laterally projecting toe block 252, engaged and acted upon by a. cam 253 in order to periodically move the valve 246 to open position.

In Fig. 1 I have also shown the rod 249,

as in my patent above referred to, provided with an adjustable set collar 25st at the rear of the frame 185 of the ruling machine, and

surrounded by ,a coiled sprin 255, extending between the set collar and the frame 185 of the ruling machine, and the action of which is to normally create a rearward tension upon the rod to maintain the valve 246 closed.

The ruling machine, of which a portion only is shown, has a train of driven gears,

of which one 'isseen at 256 in connection with a cam head 25 6, and with this gear 256 a gear 257 is movable into and out of en gagement, gear .257 being mounted upon a shaft 258 on which the cam 253 is also secured.

The cam head 256 of the ruling machine just previously mentioned is provided at one point with a peripheral indicating line 259, for coiiperation with a rigid pointer 260 secured upon a portion of the frame 185 of the ruling machine adjacent the same, and

in registry with which the line 259 may be shifted when the gear 257 is withdrawn pair of spaced annular grooves 264 and 264:, as best seen in Fig. I, and said shaft is provided at its outer end with a milled hand wheel 265 and a rigid number wheel 266, the latter located below the rigid pointer 263.

Referring now to Fig. 3, a spring 267 is rigidly secured at one end to one side of the bearing 261, and is curved beneath the bear ing, with its opposite end projecting freely in a lateraldirection to form a handle 268, and with an intermediate stud 269 which, as seen in Figs. 3 and 4, projects upwardly through a comformable opening 270 in the lower portion of the bearing 261, and into one of the annular grooves of the shaft 258.

In the normal operative position of the parts the stud 269 is engaged with the groove 264, as shown in Fig. 4, the gear 257 being at that time in engagement with the gear 256 of the driven train of gears of the ruling machine. When, however, it is desired to change the time of opening and closing of the valve 246, the handle 268 of the spring 267 is lowered, withdrawing the stud 269, so that by grasping the milled head 265, the shaft 258 may be moved longitudinally in an inward direction to disengage its gear 257 from the gear 256. By releasing the spring 267 the stud 269 will then project itself within the groove 264:, so as to secure the shaft 258 1n inner inoperative position, permitting the operator to devote his entire attention to the matter of timing.

In timing the gears, gear 256 is rotated by hand until the mark 259 registers with the pointer 260, and the hand wheel 265 is turned, rotating shaft 258, until the desired number of the number wheel 266 registers with the pointer 263, this adjustment depending upon the size of sheet utilized at that time. When proper registry is had, the spring controlled stud 269 is again pulled downwardly in the manner before specified, and the shaft 258 moved outwardly without rotation, to again engage the gear 257 withthe gear 256, so that upon release of the spring 267, upward movement of the stud 269 within theinner groove 264 will again lock the parts in operative relation.

It is then obvious that, in the further operation of the parts, the cam 253 intermittently actuates the lever 251, the latter of which is pivotally mounted at its upper end at 271, as seen in Fig. 3, to a portion of the bracket 262, in order to move the valve controlling rod 249 against the tension of its controlling spring 255.

It is apparent that my present improvements provide readily controlled valve actuating means through the use of which the operator may quickly set the cotiperating parts, in accordance with the particular size of sheet to be fed to the ruling machine, and that by so doing, considerable time and work Will be saved in the practical use of paper feeding machines in connection with paper ruling machines to which the paper is being fed.
