Application filed (ictober 24, 1916. Serial No; 127,368.

To all whom it may concern: Be itknown that I, JOHN EsTocK, a c1t1- zen of the United States, residing at Yon- 'kers, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Mechanical Move-- ments; and I do hereby declare the following to be 'a full, clear, and exact descrlptlon of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame. This invention relates to new and useful 1 improvements in mechanical movements and tension on the driving chain.

the principal object of the invention is to provide a device for increasing power.

Another object of the invention is to' provide a device consisting of a fulcrumed lever, the long end of which is driven by a suitable motor or other power generating device which lever has its short end connected to a suitabl connecting rod and crank for turninga shaft to operate a drive wheel, which may be used for turning varlous machines. r a

A still further object of the invention is to provide a novel means for adjusting the A still further object of the invention is to provide a device having a balanced lever so that the power wasted in moving the lever will be minimized. With these and other objects in view the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and.accompanying drawings, in wh1ch:

Figure 1 is a side view in elevation of a power increasing device constructed in accordance with this invention.

Fig. 2-is a top plan view of Fig. 1. Fig. 3 is an end view of the device. Fig. 4 is an end view fromthe opposite end of Fig. 3.

Fig. 5 is a vertical sectional view on line H of Fig. 3. I

Fig. 6 is a horizontal sectional view on an enlarged. scale taken on line 66 of Fig. 3.

Fig. 7 is an enlarged fragmentary detail sectional view of a pair of the standards showing the method of adjusting the bearm s.

%ig. 8 is an enlarged fragmentary sec tional view of one end of the lever showing the b alancing weight and method of securmg the same in place, and

Fig. 9 is a transverse sectional view on line 9+9 of Fig. 8.

Referring to the drawings, the numeral 1- designates as an entirety the base of the device comprising a pair of parallel side bars 2 held in spaced parallel relation by transversely extending end bars 3. Suitable intermediate bars 4 are positioned between the side bars 2 and near the end bars 3 in spaced parallel relation and extending. upwardly from the transverse bars 4: are standards 5 which are held in spaced parallel relation by suitable longitudinally and transversely extending bars 6 and 7 respectively. These bars 6 and 7 are arranged adjacent the upper ends of the standards 5 as clearly shown in the drawings. Upon reference to Fig. 2 it will be seen that the standard to the right is supported on extensions on the bars iwhich are braced by suitable reinforcing brackets 8 illustrated in the drawings. Extending upwardly from the bar 3 are suitable standends 9 connected at their upper ends by a transversely extending bar 10 and a suitable connecting bar 11 extends between the standards 9 and 5 as shown in Fig. 5.

Extending upwardly from the side bars 2 near the end of the machine opposite that to which the bars 4 are connected are suitable standards 12 and intermediate the ends of said side bars are standards 13. These standards are arranged in pairs and connected by transversely extending bars 14: and longitudinally extending bars 15. The bars 15 are recesses as at 16 and a suitable cap 17 is fitted over each of said bars and provided with recesses 18 which a-line with the re:

cesses 16 and form bearing openings in which the drive shaft of the device is mounted. Suitable braces 17 are connected to the standards 12 and 13 intermediate their upper and lower ends as clearly shown in Fig. '1. Extending upwardly from the side bar 2 on the right are standards 19 supporting at their upper endsa suitable transversely extending bar 20 which is provided with a central recess 21 and has a cap 22 fitting thereover which is recessed as at 23 to form a bearing in which the fulcrum pin is mounted. This fulcrum pin supports the lever in operative position as clearly shown in the drawings. Suitable standards 22 extend upwardly;;from the base intermediate the ends ofthe bars and serve to brace the same centrally in order from sagging. v

Mounted in the openings formed by the recesses 17 and 18 is the main drive shaft 24 carryingat its outer end the fly wheel 25 to prevent them and intermediate its ends with a belt Wheel 26. This, belt wheel is mounted between the standards 22 as shown in Fig. 4. A crank 27 is connected to the inner end of said shaft and has rotatably connected thereto a connecting-rod 28 which is pivoted at 29 to the lever designated generally by the nu meral 30. The lever 30 above referred to comprises an arm 31 provided with a fulcrum pin 32 which is rotatably mounted in the recesses 21 and 23 and this arm is provided at the end nearest the fulcrum pin with a'recess or pocket 33 for the reception of suitable weights 34. These weights are retained in place by a strap 35 which fits over the end of the lever as clearly shown in in suitable journal bearings ,50 mounted be-v ournals for the shafts 41 of the drive chain;

Suitable wedges 42 are driven into the recesses 37 beneath the guides 38 and it will thus be seen that the distance between the sprocket may be varied in order to vary th tension on the chain.

The shafts 41 are mounted between their respective pairs of standards 5 and ,the inner ends of said shafts are provided with sprockets 42 over which the chains 43 pass. The sprockets 42 are preferably positioned near the upper ends of the standards while suitable sprockets 44 are mounted in similar bearings and on similar shafts near the lower ends of the standards. The shafts of the sprockets 44 are designated by the.numeral 45 and carry suitable drive sprockets46 over which the drrvdchains' 47' pass. Thesedrive.

chains are driy en by thelarge sprockets 48 mounted on the shaft 49 which is supported tween the standards 9 and 5. I

Extending between the chains 43 and carried therewith is a suitable connecting pin 51 which extends through the slot 36 in the lever 30 so that upon movement of the chain the lever will be oscillated.

It will be apparent from the foregoing that in use the device is driven by connecting a suitable motor or engine to the belt wheel.

52 thuscausing the shaft 49 to revolve and I drive the sprockets 48 thus driving the sprocket 46 through the medium of the chains 47 which in turn drive the shafts 45 and the chains 43. Assuming that theconnecting pin 51 is carried by the runs of-the chain to the right in Fig. 5 and that the wheel 48 is operating in a clockwise direction, it will be seen that the lever 30 will move downwardly until the pin reaches its lowermost distance of travel whereupon the same will start upwardly on the opposite run of the chain thus causing the lever 30 to oscillate. The oscillatory movement of the lever will cause the shaft 24 to revolve thus operating the" fly wheel 25 and the drive wheel 26. I

While in the foregoing there has been shown and described the preferred .embodie ment of this invention, it is to be understood that such changes may be made in the combination and arrangement of parts as will fall within the spirit and scope of the invention as claimed.
