Description
UNITED STATES E. P. RUSSELL, OF MANLIUS, NEW YORK.
IMPROVEMENT IN DRIVINGr-WHEELS OF HARVESTERS.
Specification forming part of Letters Patent No. 49,439, dated August 15, 1865.
pattern-face up (with the pins init) on the mold-board. Fig. 2 represents the pins as they are placed in the tlask or mold at the time of casting. That part of the drawing represented as wood is, in practice, of iron or sand. Fig. 3 shows the manner of attaching the friction-rollers to the driving-wheel after it is cast.l
The nature of my invention consists in cast- :ing the driving-wheels ot' harvesters, horsepowers, &c., around the pins of their frictionrollers, so as to dispense with the necessityof y. drilling the pinholes; also, in casting the pin and its hole in the friction-roller with smoothchilled surfaces.
In the drawings, A represents the drivingwheel. This wheel is some four feet in diam'- eter. Only a cross-section ofit is shown in the drawings.
B is the friction-roller. Each driving-wheel is provided with some twenty of them, working on equidistant pins in the rim of the wheel.
C is the pin upon which the roller B plays. Its head is countersunk in the roller. Th other end of the pin passes through wheel A,
and is rigidly secured thereto by the nut a..
E represents the mold-board; F, the sand and ask.
The friction-pulley B is cast upon a steel pin. When nearly cool the pin is driven out by a blow ofa hammer, so as to leave a smooth, hard-chilled hole for the pin G. The pin C is made by placing a wroughtiron pin (having a thread on the upper end) in a metallic mold.
The molten iron is then cast around the Wroughtpin, thus producing the pin C of about an inch and a quarter in diameter with a hard, smooth :chilled surface and a suitable head to ll the countersunk hole of the pulley.
My improved mode of casting thewheel, is as follows: I first take a'idriving-wheel pattern (or a linished driving-wheel) and drill and countersink the necessary number of pin-holes at equal distances apart in it. I then place the pattern upon the mold-board E' (see Fig. 1) face upward, and insert the pins C, as shown, in their holes. The mold-board is then filled with sand. I then turn the mold over (see Fig. 2) and withdraw the pattern, leaving the pins in their proper places in the sand and mold. The metal is then run into the mold, thus casting the wheel around all the pins. By this means I am enabled to dispense with the necessity of the labor and the cast-iron wheel, cure a better and a tighter t ot' the pins in their holes. When the wheel is cool it is rc- Inoved from the mold. A slight blow ot' a hammer upon the pins will drive them out ot' their holes. As each pin is removed itis put through a friction-pulley, B, andthen replaced in the same hole, and the nuta is then put upon it and drawn up closely, so as `to hold the pin immovablptight in the wheel. (See Fig. 3.) I
By my invention the pulleys, havingchilled holes working around chilled pins, wear a much longer time and with less friction (and at less cost) than it' the holes were drilled and the pins turned, and the pins are more uniformly equidistant and tighter in the wheel than would be the case if each wheel had to be measured and laid of and each hole drilled.
Having thus fully described my invention, what I claim as new, Letters Patent, is-
The combination of the drivingwheel A, the pin C, and friction-roller B, constructed in the manner and arranged substantially as described.
In testimony that I claim the above I have hereunto set my hand this 3d day 1865.
of April,
E. P. nUssELL.
