UNITED STATES PATENT OFFICE.
WESLEY E. LAIRD, OF MONTPELIER, VERMONT, ASSIGNOR OF ONE-HALF TO FRED H. PERRY AND BERT R. DEMERITT, OF SAME PLACE.
DEVICE FOR TRANSMITTING POWER.
SPECIFICATION forming part of Letters Patent No. 439,803, dated November 4, 1890.
Application filed March 26, 1890. Serial No. 345,465. (No model.) i
To all whom it may concern:
Be it known that I, WESLEY E. LAIRD, a citizen of the United States, residing at Montpelier, in the county of Washington and State of Vermont, have invented certain new and useful Improvements in Devices for Transmitting Power; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
- This invention relates to improvements in devices for transmitting power, which will be hereinafter more particularly described and pointed out.
In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of the invention. Fig. 2 is a side elevation of a modification. Fig. 3 is a plan View, enlarged, of the frame supporting the belt-pulley.
The object of thisinvcntion is to economize I space and to facilitate the adjustment of the belt to the driving-pulley.
In an electric-light station valuable spaceis occupied by long and expensive belts, requiring long lines of shafting and many bearings, Some device is also required to stop and start a dynamo at pleasure. This is usually accomplished by belt shifters and clutch-pulleys, all of which are expensive and soon prove a nuisance from getting out of order.
With the device herein to be described and illustrated I am enabled to run two machines in one-fourth of the space usually occupied for one, and by a simple device can stop, or start one machine without interfering with the other. This is accomplished with onefourth of the belting and shafting and with a less number of pulleys and bearings, &c., than now used, and without the usual beltshifters or clutch-pulleys.
A A A in each of the figures represent the dynamo-pulley.
B B is the main driving-pulley.
C O O is an adjustable pulley, which is supported in a frame E E E.
D D D is an endless belt, which passes around the pulleys A A A" and C C O, and in Figs. 1 and 2 is represented as clasping about one-third of the periphery of the driving-pulley B B.
In Fig. 1 two dynamo-pulleys A A are shown, which are to be operated by the pulley B. The frames E E in Fig. 1 are sustained in hangers F F, which are secured to the ceiling of the room. G G are sleeves,
which slide freely on the vertical rods F F of hangers F F. H H are bent levers, pivoted on rods R R, supported in the hangers F F. Each leverHH has a spring-pawl h h to engage with a ratchet r 1", attached to the rods R R in the hangers F F to secure the sleeve F in any desired position. At the end of the short arm H of the levers H H there is a connecting-yoke O O, which is pivoted to H", and also to apin K, which passes through the sleeves G G. The frames E E swing between -the sleeves G G, which can slide upon the rods F whenever the lever H H is moved in either direction. The sleeves G G support the frames E E by means of the pin K, which passes through the end of the frame. The sleeves G G aresupported by the yokes O 0, attached to rod K and to the end of lever H. By bringing down the lever H to the position shown in dotted lines the idler-pulley O, with the frame E, will be drawn away from pulley B, as seen in dotted lines. When the belt is required to be used, the frame E is swung back by hand and the belt is tightened by means of the lever H.
Fig. 2 represents a modification. A is the dynamo-pulley. Bis the driving-pulley. C 1s an idler-pulley sustained by a shaft e on the top of a frame E, which frame is pivoted at e to the base-block F secured to the floor. Attached to the frame E is an arm 9, in the outer end of which is pivoted a threaded nut G, through which is fitted a screw-bolt I, pivoted to a floor-block I at 1', having a handwheel H for its adjustment. By moving the arm g upwardly the belt D will be tightened, and vice versa.
I claim- The combination of the driving-pulley, the idler C, the driven pulley A, the belt D, the frame E, sleeve G, rod F, yoke O, ratchet 4', and lever H, substantially as and for the pur pose described.
In testimony whereof I affix my si gnatu re in presence of two witnesses.
WESLEY E. LAIRD.
