JOHN E. MOINTOSH, OF AUBURN, NEW YORK.
ENGINE-CRANK.
SPECIFICATION forming part of Letters Patent No. 360,711, dated April 5. 1887.
Application filed February 10, 1857. Serial No. 227,135. (No model.)
are sufficient to balance the crank and con 5 To all whom it may concern.-
Be it known that I, JOHN E. MolN'rosH, of the city of Auburn, State of New York, have invented certain new and useful Improvements in EngineOranks, of which the following is a description, reference being had to the accompanying drawings.
The object of my invention is to balance the reciprocating parts of an engine. This object is accomplished by means of a novel construc tion of the cranked axle of the engine and the combination therewith of a balancing-weight of novel construction, by means whereof the crank, crank-pin, and connecting-rod are effectually balanced with the least weight of metal and the construction of the above-mentioned parts much simplified in comparison with the devices heretofore used to produce a like effect.
In the drawings, Figure 1 is a side view of the cranked axle of an engine, showing the balancing-disk in section upon the line :0 y of Fig. 3. Fig. 2 is an end view of the cranked axle and collar thereupon; and Fig. 3 is an interior face view of the cranked axle, collar, and balancing-disk.
A cranked axle, a 7) db a, is formed with the collars c c concentric with the axle a a and adjacent to the crank I) I). The collars are integral with the axle a a and crankarms b b, and the peripheries of said collars are turned in a lathe to make a fit with the balancing-disk, which latter is bored to fit thereon, as shown in the drawings. The balancing-disks are two in number, and adapted to the collars c 0, although one only is represented in the drawings. They consist of a hub, 6, connected by a Web, f, with a peripheral rim, 9, of about the thickness of the crank-arms b and collars c. This peripheral rim is for appearance and for concealment of the crank simply.
The counterbalancing-weight h is cast solid with the web f and rim 9, of which it forms a part, and the weights of both balancing-disks nected reciprocating parts, as above mentioned. The diskfis provided further with a lug, is, upon the web thereof, opposite the weight 71, which lug is finished to fit the end of the crank-arm b, and is secured thereto by 0 a key, m.
Between the collar 0 and the hub e of the disk I insert the plugs a a n to further secure the disk, and these plugs are threaded,screwed to position, and cut off flush with the faces of 5 balancingdisks mounted upon said collars, 65
substantially as described.
2. The combination of the shaft, crankarms, crank-pin, and collars concentric with the shaft, all integrally constructed-with balancing-disks mounted upon the concentric (101- 0 lars, and having their rims concentric with the shaft, substantially as described.
3. The shaft, crank-arms, cranlcpin, and concentric collars, in combination with balancing'disks provided with lugs k, fitted to the 7 5 end of the crank-arms and secured thereto by the key m, substantially as described.
4. The shaft, crank-arms, crank-pin, and concentric collars, all integrally constructed,
in combination with balancing-disks fitted 8o upon said concentric collars and secured thereupon by the screw-threaded plugs n n a, substantially as described.
