MATTHEW H. KOLLOOK, OF PHILADELPHIA, PENNSYLVANIA.
IMPROVEMENT IN Dumm-ENGINES.
Specification forming part of Letters Patent No. 137216,. dated March Q5, 1S? 3.
To all whom it may concern:
Be it known that I, MATTHEW H. KoLLooK, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented anew and valuable Improvement in Steam-Engines for Street-Cars 5 and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification and to the letters and iigures of reference marked thereon.
The drawing is a side elevation of a section of a car embodying my improvements.
My invention has reference to that class of locomotive-engines known as dummy, and particularly to those employed for street-ears, where the engine and boiler are placed on the front platform ofthe car, and is an improvement on the patent granted to R. H. Long, dated January 24, 1860. The object of my improvements is twofold: rst, to do away with the rattling noise which has heretofore rendered these engines so objectionable; and, secondly, to prevent the rising-aud-fallin g motion of the car upon its springs from breaking the teeth ofthe gear-wheels.
In engines of the class to which my improvements particularly relate a vertical or upright boiler is employed 5 and it has been found necessa-ry for obvious reasons to communicate motion from the piston-rod to the gear-wheel by means of an intermittent pinion.. The gearwheel is, of course, mounted on the car-wheel axle; and heretofore the boxes of this axle were arranged to move vertically in straight bearings as the body of the car was raised or lowered on its springs. The pinion was placed on the same pla-ne with the drivin g-wheel, because, if placed above or below it, the movement of the car on its springs would jam the pinion and gear-wheel and break their teeth. For the same reason the pinion and gear-wheel were geared loosely, and hence arose the objectionable noise already referred to. To obviate these defects, to gear the pinion and wheel snugly, and always to preserve their close contact without incurring the breakage of their teeth, is the object of my improvements. My invention, then, consists in locating the pinion on a plane either above or below that of the gear-wheels, and in constructing the boxes of the car-wheel axle to move in curved bearings concentric with the pinion.
In the drawing, A is a section of a streetcar with an upright boiler, B, on the front platform. C shows the cylinder, which will have a piston-rod connected by a crank-arm with the pinion D. E is the ear-wheel, and E a gear-wheel on the same axle meshing with the pinion D. The axle of the pinion, it will be observed, is on a plane above that of the car-wheel axle, for the purpose already described. It may be placed on a plane below that of the car-wheel axle with the same result, but I prefer the arran gement-illustrated. The boxes of the car-wheel axle are shown at F. They are made with curved sides adapted to the bearings F', which bearings are concentric with the axle of the pinion` D. By this means the pinion D and wheel E remain always in gear, whether the body of the car be elevated or depressed upon its springs.
What I claim as my invention, and desire to secure by Letters Patent, is
l. The arrangement of the pinion D either' above or below the horizontal line-of the caraxle, but parallel therewith, to allow the spring to be4 independent of the axle, and still keep the pinion in gear.
2. The combination of the pinion D, arranged as described, and the concentric bearings of the car-wheel axle.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
MATTHEW H. KOLLOCK.
