(Cl. '7-i-428) 4 Claims.

This invention relates to a counting mechanism and more especially to a novel means for selectively driving any one of a plurality of resistering devices from the same source.

The invention is particularly applicable to pick counters which are used upon looms in textile mills to keep an accurate record of the production of the loom for each shift. Where a loom operates only one shift each day, it is only necessary to have one registering device; whereas if there are more than one shift; the number of registering devices must be increased accordingly. It is evident that where two shifts a day are operating in the mill, it would be useless to place a triple registering counter on the loom; whereas if a dual register is installed upon the loom and the mill changes from two shifts a day to three, then it will be necessary to add an additional registering device.

It is, therefore, an object of this invention to provide a counting mechanism constructed in separable units which may be easily attached or detached from a loom to increase or decrease, respectively, the registering devices according to the number of shifts operated.

It is a further object of this invention to pro vide a counting mechanism comprising a casing having a plurality of registering devices therein, and a second casing detachably mounted thereon which has another re istering device therein with means including a drive shaft, for driving the fist registering devices selectively and also means for disconnecting said second registering device upon a selected connection with one of the first registering devices. By providing a structure of this type, it is possible to have detachable counters which may be joined together when the shifts in the mill are increased, thereby making it possible to use a minimum number of registering devices.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds, when taken in connection with the accompanying drawings, in which- Figure l is an isometric view of a counting mechanism embodying the invention;

Figure 6 is a vertical sectional detail view taken along the line 6-6 in Figure 3.

Referring more specifically to the drawings, the numerals l8 and Ilindicate lower and upper casings having covers I2 and [4 respectively secured to the front side thereof. The cover i2 has apertures l5 and I6 therein, whereas the cover l4 has an aperture l1 therein. Through the apertures i5 and it, suitable figure wheels l8 and 19, respectively, are visible and these figure wheels have suitable figures thereon which when disposed opposite their respective apertures, will indicate an accurate reading of the number of operations performed by a machine. The aperture IT has figure Wheel 23 visible therethrough which is similar in all respects to figure wheels l8 and ill just described.

The figure wheels 18, I9 and have associated therewith suitable gears 2|, 22 and 23 which are adapted to mesh with pinions 24, 25 and 26 on shaft 27, 28 and 29 respectively. The function of the last-named pinions is to properly rotate the figure wheels to cause an accurate reading to be registered. The figure wheels l8, I8 and 20 are rotatably mounted around shafts 3D, 31 and 32, respectively. These shafts have gears 33, 3 and rotatably mounted therearound, said gears being directly connected to gears 31, 33 and 39 and the figure wheels, by means of p-inions 24, 25 and 25.

Meshing with the gears 33, 34 and 35 are worms 4!), ill and The gears and 4| are rotatably mounted around sleeves 46 and 41 (see Figure 2) which sleeves act as bushings for a vertically disposed drive shaft 43. The lower end of shaft 38 has a fitting 49 secured thereto secured to the lower end of this fitting is a link 53, which link is also secured to another fitting 5!, said fitting 5! having a rod 52 secured to the lower side thereof which is driven by the machine upon which the counting mechanism is mounted.

Disposed around drive shaft 43 and between the worms 4%) and 4| is a grooved member 55 having spring pressed plungers 5B and 51 in opposed ends thereof which are adapted to engage notches 58 and 59, respectively, in the end of worms M1 and 4!. Of course, these plungers are only allowed to penetrate these notches when it is desired to connect drive shaft 48 to a 2 particular set of figure wheels. It will be noted that the member 55 is slidably keyed as at so to shaft 48.

The grooved wheel normally meshes with a gear segment ill on shaft (52. I'his shaft extends through the front cover 52 and has mounted on its outer end a suitable operating knob 64. Fixed in the face of this knob and adjacent the face of the cover if is a pin $5 which fits into either one of cavities es, bl or 68 in the face of the cover, depending upon which counting mechanism is desired to be connected to the drive shaft. This pin 65 is normally held in the selected cavity by means of a compression spring 69 disposed around shaft 52, which spring has one end thereof abutting against the inner face of cover l2 and its other end disposed against a cam l6 which forms an integral part of the shaft. When it is desired to move the grooved wheel upwardly into engagement with the worm 4 i, it is necessary to pull the shaft 62 and its associated knob 64 to the right in Figure 2 or toward the observer in Figure 5, and then rotate the knob in a clockwise direction in Figure 5, until pin will be disposed opposite cavity (it, at which time the knob may be released and the spring 63 will force the pin 65 into this cavity. When it is desired to connect the shaft 43 with the lower worm ail, the knob is turned in an opposite direction until the pin 65 can be released into cavity 58. In other words when pin is disposed in cavity 65 the figure wheels is are connected to shaft is and when this pin is in cavity 63 the figure wheels 58 are connected.

The worms l9 and M are normally held in stationary position, when disengaged from the groove wheel by means of spring-pressed dogs 15 and 5%, respectively. All of the above described mechanism is substantially shown and described in my co-pending patent application, Serial Number 242,824, filed November 25, 1938. It is thought, however, to be necessary to show this much of the former embodiment in order to more clearly disclose the advantages of the present invention.

As heretofore stated, one of the primary objects of this invention is to provide an apparatus where one or more additional registering devices may be superposed upon the present device to take care of additional shifts which might be put on in the mill. Since it is necessary to provide a registering device for each additional shift in the mill and since the number of shifts in a mill vary from time to time, it naturally follows that means must be provided whereby the number of registering apparatus may be varied accordingly. I have therefore provided a novel means whereby the additional counter may be added without disturbing the advantages of the original unit.

The upper end of the drive shaft has a cavity 88 therein which cavity has a diametrically disposed pin 8! therein fitting in a groove 32 in the lower end of a shaft The shaft 83 is axially alined with the shaft 48 and is slidably mounted in the upper casing i l In the position shown in Figure 2, the shaft 83 is connected to the shaft 43, therefore, the registering device in the upper casing driven by the shaft 83 will be operated.

The intermediate portion of the shaft 83 has a diametrically disposed pin therein the ends of which are disposed in longitudinally disposed grooves 85 in worm 22. Also fixedl secured around an intermediate portion of the shaft 83 is a grooved collar 82 by any suitable such as diametrically disposed pin 89. This grooved collar is adapted to accommodate a fork member which fork member is fixedly secured around a vertically disposed shaft 9|, said shaft 9| (Figures 2 and 6) being mounted for vertical sliding movement in the upper casing I I as well as in the upper portion of the lower casing ID. A spring 92 normally forces the shaft Hi downwardly and thereby forces the notch 82, in the lower end of shaft 83, into engagement with the pin 8! in the upper end of shaft 43. It is, therefore, seen that when it is desired to disconnect the upper registering device from the shaft 48, that the upper shaft 83 must be raised by means of the shaft 9|, so that the notch 82 will be raised to such an elev tion that it will not engage pin 8|.

The lower end of the rod 9| is adapted to rest upon the upper end of a member I90, said member being slidably mounted in bosses NH and l 02 (Figures 3 and 6), which are integral with the sidewalls of the lower casing ID. The member ifiil is normally confined in suitable grooves in these bosses by means of plates Hi3 and I04, respectively. By referring to Figure 3, it will be noted that the intermediate portion of member 580 has a notch H35 cut therein in which the cam member 10 is adapted to operate. The upper side of this notch is substantially horizontal and is allowed to rest upon the upper portion of this cam. When in the position shown in Figure 3, neither of the registering devices in the lower casing Id is connected to the drive shaft 48, but the upper registering device in casing 14 is connected since the pin 8! in the lower shaft fits into the notch 82 of the upper shaft.

Let us suppose that it is desired to connect the upper registering device in the lower casing, that is, connect the apparatus so that the figure wheels [9 will be in operation. Then it is only necessary to turn the operating wheel 64 in a clockwise manner in Figure 5, which will cause the shaft 82 to rotate in a clockwise manner in Figure 3. Upon the rotation of this shaft 62 in this manner, the cam 18 will raise the member 1% and at the same time raise the rod 9|. Since this rod 9| is connected to the associate drive shaft 83, this shaft will likewise be raised so as to disengage its lower end from the upper end of drive shaft 43.

When it is desired to connect the drive shaft with the lower counting mechanism in the lower casing, that is to cause the figure wheels I8 to be in operation, then the operating handle 64 is turned in a counter-clockwise manner (Figure 5) which will turn the shaft 62 and the cam 10 in a counter-clockwise manner in Figure 3. This motion will likewise cause the upper shaft 83 to be raised to a disengaged position.

As heretofore stated, when it is desired to have the upper casing only in operation, the parts are placed in the position shown in Figure 3 at which time the lower registering devices will be out of operation; whereas the upper device will be in operation due to the fact that the shafts 83 and 43 remain connected because the low side of cam if is supporting notch ms in lifting member I03.
