DRIVING-WHEEL.

Original application filed June 14, 1915,

, which the following is a specification.

This invention relates to a device for transmitting motion to instruments of various kinds, as, for example, a counter of the kind shown in the drawing, and this application is a division of my copending application Ser. No. 33,898, filed June 1 1, 1915.

The invention has for its object the provision of a device of the character named which shall be of improved construction'and operation.

The invention is exemplified in the combination and arrangement of parts shown in the accompanying drawing, and described in the following specification, and it is more particularly pointed out in the appended claims.

In the drawing Figure 1 is a side elevation of one form of wheel embodying the present invention;

Fig. 2 is a sectional view substantially on the line 22 of Fig. 1; p

Fig. 3 represents the wheel shown in Fig. 1 as applied to a counter, a portion of the wheel being broken away;

Figs. 4 and 5 are elevational and sectional views respectively'of a washer forming a part of the present invention; I

Figs. 6 and 7 are detailedviews representing one of the arms of the wheel shown in Fig. 1; and

Fig. 8 is a section On the line 88 of Fig. 6.

In the operation of a counter such as that shown in the drawing, itis desirable to produce a partial rotation of the countershaft each time an object to be counted passes a given position relative to the counter. The particular embodiment of the present invention is especially designed to produce this result, but it is obvious that the invention may be applied to wheels for a great variety of purposes, and applicant does not wish to confine himself to any particular use to which his invention may be put.

The wheel shown in the drawing is repre sented as having four arms, but it is apparentthat' the number of arms may be varied Specification of Letters Patent.

to suit particular requirements. A wheel for the purpose indicated must be light and strong and in order that it may be shipped in the same box with the counter or'other instrument with which it isintended to be used, it should be capable of being taken apart and assembled readily. This, of course, is a. valuable characteristic, even when the wheel is shipped separately, because it permits of packing in a small space. The embodiment of the invention shown in the drawing inoludesfour arms 10. Each of these arms is made of a single piece of sheet metal bent in its middle,- as indicated at 11, and having the inner ends spaced apart so that the arms, when assembled, form a closed triangle, thus giving a strong construction of light weight. Astruck-up portion 12 extends longitudinally of each section of the arms, to insure rigidity. The inner ends of the arms are bent inwardly, as shown at 13, and each inwardly bent-portion is provided with two lugs 14. When the tions of the arms abut against one another, and the lugs 14: of one arm register with the lugs 14: of the next arm, as shown in Fig. 1.

Two disks 15 areprovided, each having four wheel is assembled, the inwardly bent poropenings 16fth'erein adapted to fit over the V double purpose of forcing the star wheel onto the shaft and holding the disks 15 together. If it is desirable to adjust the position of the star wheel relative to the shaft,

all that is necessary is to loosen the nut 20 which will leave the wheel free to be rotated about the shaft. When' the nut is again tightened, the wheel will be forced onto the tapered portion 19 and will again be in position to rotate the shaft 18 prevent lateral crushing of the the pressure of the nut. g

It will be seen that the construction described provides a light, skeleton structure which is strong and 'rigid'when assembled arms by The bends 13 and which may be easily placed in position upon the shaft to be driven, and which may also be easily taken apart and placed in small compass for shipment or other purposes.

I claim:

1. A take down star wheel for a counter, comprising thin sheet metal arms having struck-up reinforcing ribs longitudinal thereof.

2. A drive wheel having arms made of sheet metal bent at the central portion, thus forming supporting sections at an angle to one another, and means for securing said sections to said wheel in separated relation to one another so that said sections form two sides of what is in effect a closed triangle of which the portion of the wheel to which said sections are secured forms the third side.

3. A drive wheel comprising a plurality of arms made of sheet metal and having two supporting portions meeting at the outer extremity of the arms and separated at the inner portion thereof, and means for securing said separated portions in fixed relation to each other.

4. A drive wheel comprising a plurality of arms made of strips of sheet metal bent upon themselves, the ends of each strip having bent portions abutting against similar portions of the strips forming the adjacent arms, and means for securing the abutting portions together to form the wheel.

5. A drive wheel comprising a plurality of arms made of bent strips of sheet metal, having projecting lugs thereon, and disks having openings therein positioned over said lugs to hold said arms in fixed relation to one another.

6. In combination, a drive shaft having a tapered portion thereon, a drive wheel for said shaft adapted to bear on said tapered portion, and a threaded member arranged to force said drive wheel onto said drive shaft.

7. In combination, a drive shaft having a tapered portion thereon, a built up drive wheel having a pair of disks for holding said drive wheel in assembled relation, and hav ing openings therethrough to receive said drive shaft and a nut threaded on said drive shaft and arranged to hold said disks in operative relation and to secure said wheel to said drive shaft.

8. A take-down star wheel for driving counters and similar devices, comprising arms formed by strips of sheet metal bent upon themselves at the outer ends of the arms, and having the inner ends thereof spaced apart and held in fixed position rela tive to one another the contiguous portions of adjacent arms being braced against one another.

9. A take-down star wheel for counters and similar devices, having a plurality of arms formed from strips of sheet metal bent upon themselves at the outer ends of the arms, and having longitudinally struck-up portions therein to strengthen said metal strips.

10. A take-down star wheel for driving counters and similar devices, comprising a plurality of separable arms, and means for locking said arms in fixed relation with one another and for holding said star wheel in place upon the instrument to be driven.

11. A take-down star wheel for driving counters and similar devices, comprising a plurality of separable arms, hub members removably connected with said arms for detachably holding said arms in fixed relation to one another, and means for holding said wheel upon the portion of the device to be driven and for securing said hub members and arms in fixed relation with one another.

12. A take-down star wheel for driving counters and similar devices, comprising a lurality of arms formed by bending reinforced strips of sheet metal upon themselves, the bent portion of said strips forming the extremity of said arms, while the inner ends of said strips are bent inwardly to form abutment members which cooperate with abutment members of adjacent arms, later ally projecting lugs on the inner ends of said arms, and a disk having openings therein arranged to receive said lugs and to hold said arms in fixed relation to one another.

13. A star wheel for driving counters and similar devices, said wheel having arms thereon, each arm being composed of members arranged to form with the hub of the wheel a closed triangle.

14. In a drive wheel, an arm comprising a strip of sheet metal having a portion thereof bent laterally relative to the plane of said strip and serving to strengthen said strip against crushing action in the direction of the plane thereof.

15. In a driving wheel, an arm comprising a strip of sheet metal having a portion thereof bent relative to the plane of said strip to form an angle in said strip for strengthening said arm against lateral pressure, and means for exerting pressure on said arm adjacent the bent portion thereof and in the direction of the line on which said strip is bent, to hold the parts of said wheel in place.

In testimony whereof I have signed my name to this specification, on this 2nd day of November A. D. 1917. 7
