INTERMITTENT-OPERATING MECHANISM.

Specification of Letters Patent.

Patented Nov. 14, 1911.-

Application filed December 29, 1910. Serial No. 599,899.

To all whom it may concern:

Be it known that I, NoRRIs V. YOUNG, a citizen of the United States, residing at Wilsonville, in the county of Clackamas and State of Oregon, have invented certain new and useful Improvements in Intermittent- Operating Mechanisms, of which the following is a specification.

This invention relates to an improvement in intermittent operating mechanism and has for its object to provide an attachment for presses and machines requiring an intermittent motion, whereby certain parts thereof may be set into operation at a given moment; and further that the frequency of such motion may be varied and controlled.

The invention further consists of certain novel features of construction and arrangement of parts which will be hereinafter described in detail, and pointed out in the claims.

I accomplish these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is an enlarged bottom plan of a switch mechanism. Fig. 2 is a top plan of driving mechanism, partly in section. Fig. 3 is a plan of measuring portion of my improved mechanism. Fig. 4 is a side elevation of a cam wheel and other parts. Fig. 5 is a side elevation of a measuring wheel, showing the teeth in part. Fig. 6 is a detail view of a track containing switches and operative machinery. Fig. 7 is an' enlarged detail of the switches and is a detail 'of an inlet switch. Fig. 9 shows the tracks with a difi'erent means for operat ing the inlet switch. Fig. 10 is a detail of a modified form of inlet switch. Fig. 11 is a bottom plan of Fig. 9. Fig. 12 is a detail of a member of the outlet switch. Fig.1?) is a detail of a brake. Fig. 1 1 shows the driving link as it is about to leave its engagement with wheel 1 to enter the inlet switch.

Similar characters indicate similar parts throughout the several views.

In the drawing 1 designates the framework of a baling press or any machine upon which my device may be applied. Mounted in the said frame are the shafts 2 and 2* operating in the bearings 3 and 3* respectively and with which are integrally formed their respective gear wheels E and E.

vWithin the hollow shaft 2* is secured the ward movement.

bearing shaft 1 and upon the outer end of which is firmly secured, by means of a key, or otherwise, the large wheel 1. Formed integrally with the hollow shaft 2*, at its outer end, is the crank 1", against the base of which the inner boss of wheel l bears.

The drive wheels E and E are operated by any suitable motor through the gearing E. As they are rotated on their bearings, the plunger rod D, which is pivoted to the crank pin d, formed upon the oppositely arranged spokes of the said wheels E and E, is made to reciprocate with each revolution, driving with it a plunger head 5, carrying compressed material 5 by which, teeth of wheel F mounted on the shaft J, which has its hearing at a convenient point on the framework 1, are engaged, and thereby rotat'ed a distance equal to thickness of material compressed by the plunger in one for- This movement causes shaft J to revolve, carrying forward crank K, the pin of which projects between the spokes of wheel M; and after moving over the space between two adjacent spokes the pin contacts with the adjacent spoke, carrying the wheel around with it. When the drive wheels shall have made a sufficient the wheel F to make one complete turn, the operative mechanism of the device will then be set in motion.

Let it be assumed that the cam wheel M,

,mounted on the end of the shaft J outside of the frame 1, is in the position shown in Fig. 4, and that the machine is in operation.

With each stroke of the plunger rod, when material to be pressed reaches the measuring wheel, the cam wheel will be turned a short distance in the direction of the arrow as above stated, and the shoe 0, will describe a corresponding distance on the periphery thereof, until it reaches the recess Q, into which it will move, in response to the action of spring S on the rod P at the end of which said shoe is mounted. The rod P is pivotally connected to the link T, which, in turn is pivotally connected to the crank arms U and V, as shown most clearly, in detail, in Fig. 7. The said arms are rigidly connected to what may be termed the outlet switch point stub shafts W and X respectively, on which are rigidly fixed switch When the arm U is carcomes to its closed lied tothe right by the above described movement of the rod P, it swings the switch point Y downward. At the same time the arm V swinging to the right, causes the switch point Z to turn upward to the stop Z, leaving the space between said points open, for a purpose to be hereinafter described. It will be observed by reference to Figs. 1 and 6, that a track 1, formed concentrically about the shaft 1, is secured upon the frame 1, the said switch points forming a portion thereof. As above stated, the crank 1 is formed at the outer end of the hollow shaft 2 and rotates under the flanged periphery 1 of the wheel 1*. To the outer end of the crank is pivoted a link 1 carrying at its free end the fixed shank 1 secured at right angles to the link and of a length which permits it to rotate without striking the frame. The end of the shank is journaled at a point opposite the track 1, to receive the guide wheel 1 When the track 1 is closed and the wheel 1 is being rotated at its inner face, as shown in Fig. 6, there will be no interruption of this continuous movement until the circuit of the track is broken. The lug 1 on the crank 1 prevents the link from dropping inward away from the track. As was seen above, the revolution of the drive wheel, which carries the crank 1 and the wheel 1 also operates the plunger rod D, which causes the shaft carrying the cam wheel M to rotate. Again, it was seen that when said wheel M rotates till the shoe 0 enters the recess Q, that movement of the rod P will throw open the switch points Y and Z, with the latter standing directly in the pathway of wheel 1 Continuing the revolution, wheel 1 will pass through the switch to the outside of the track where it will move freely at the periphery thereof. After it emerges, the link engages the lug 1 and drives the wheel 1 along with it. Moving on thus, the wheel 1 contacts with the lower tongue 1 of the inlet switch 1*, rotating it on the pivot 1 so that the rear end thereof drops into the path just passed by 1 This revolution of 1 sets in motion those portions of the machine whose activity is required only at stated intervals. Upon completion of a revolution at the periphery of the track, the wheel 1 contacts with switch point Y, forcing it into closed position in the track and carrying with it link T to the left, which also closes point Z. The end 1 1 of the switch l standing in the path of wheel 1', against the stop 1 switches the wheel to the inside of track 1 again, and, as it passes on, it moves over the upper tongue 1 of the inlet switch, rotating it on its pivot till it position and completes the track. When the link T and rod P were carried to the left, as above described, it released shoe 0 from the recess Q; and cam the inlet switch opens to wheel M, which is free to swing on shaft J, is rotated by the eccentric weight N, to the position had in the beginning. This free rotation of M is limited by a crank pin L projecting from crank K, which is rigidly connected to shaft J, as described above and shown dotted in Fig. 4.

Inlaid in the side of the track is a plate 6, held by bolts 7 and 7, adapted to bear against the inlet switch, to hold it from free rotation, the spring 8 being provided to sustain the plate, but yet to allow it to yield sufliciently to permit the switch to move, in response to the action of wheel 1.

Upon the frame is secured a brake 10 provided with a shoe 11 to bear against the stop 11 on the inner edge of the wheel 1 for holding it in position for the succeeding operation.

When the rod P is pulled to the right by spring S, it also pulls link T containing the slot 12, in which the pin 13 of the latch lever 14 operates, by pulling it fro-m under the inlet switch, thus opening the latch. This lever is pivoted by shaft 15 in the bracket or support 4: and to its outer end is secured the spring S fastened by its opposite end to link T at 16. The movement of the wheel 1 after it enters the inlet switch, forces the latter into position, against the latch, which is free to move against the tension of the spring S, and as it does so, the latch 17 comes in place beneath it, holding the switch closed, till opened again by the operation as above described.

In the machine as above described there is a unit revolution of the driver 1 outside the track 1". It may be desired to provide a plurality of consecutive revolutions in that ,position; and I have shown in Fig. 9 a

mechanism whereby the driver will traverse the outside of track l more than once, before permit the guide wheelto return within the track. Here the shaft 1 is extended sufliciently to receive the pinion 30; and upon the frame is secured the bracket 38, in which is formed a bearing to receive the shaft 29 carrying the gear 31, meshing with the pinion 30. Upon the lower part of the frame 1 is secured the bracket 37 provided at its lower end with the wide bearing 40, to receive the shaft 39 of the bell crank 32. the front end of said bell crank is secured the roller 36, and to the other end is pivotally secured the link 33, which is pivotally secured at the other end to the arm 34, which is rigidly secured upon the pivot shank 1 of the inlet switch P. In the operation of the machine, the guide wheel 1 will travel at the inner face of the track 1 To what may be called as above described, till the outlet switch is opened by the spring S. As the guide wheel emerges through the track, the. link 1 engages the projection 1 at the point where framework, a shaft mounted it previously left it, when entering the inlet switch, as shown in Fig. 14-. The wheel 1, as it revolves, carries with it pinion 30, which is secured thereto. The pinion, in this case, is formed with one-half the number of teeth contained by wheel 31, and, therefore, makes two revolutions to one of the latter, though the comparative number of revolutions may be varied to suit the work at hand. Upon a spoke of wheel 31 is formed a cam 35, adapted to contact with the roller 36, when in the position shown in dotted lines in Fig. 9, when the inlet switch is closed. The cam forces the roller 36 to the position in full lines, rocking the bell crank on its shaft, which in turn pushes the link 33 to the rear, carrying the arm 34: with it, there by rocking the inlet switch on its pivot, leaving it open to receive the guide wheel, upon its return to that point. The switches will be closed in the same manner as formerly described, the wheel 1 contacting with the tongue P, of the inlet switch, after having closed the outlet switc Having thus described my invention what I claim as new and desire to secure by Letters Patent, is-
