Description
UNITED. STATES PATENT rrrcn,
BENJAMIN H. SNAVELY, OF PENN TOVNSHIP, LANCASTER COUNTY, PA.
IMPROVEMENT IN SEPRATORS.
Specification forming part of Letters PatentNo. B019530, dated April 5, 1870.
To all whom it may concern,.-
Be it known that I, BENJAMTN H. SNAVELY, of Penn township, in the county of Lancaster and State of Pennsylvania, have invented certain Improvements in Separators, of which the following is a specification.
The principal part of my invention relates to the regulation 0f the blast of the fan by means of aweighted lever-arm which is so arranged as to give the fan-shaft an eccentric bearing on one side and cause the belt to slacken, and thereby diminish the speed and make it self-adjusting, so as to keep it up to a fixed point, according to the adjustment ofthe weight on the lever-arm.
The drawings illustrate the construction, as well as minor improvements not specially claimed.
Figure l is a side elevation of theeonstrue `severally anticipated in the patents of Messrs.
Bergen, Osborn, and Geiser, differing, however, in the arrangement and combination, that perhaps might entitle me to some claim. I will, however, simply mention them: First, the trough T of' the conveyer has a threefold triple crank, Q Q, to which nine rakes are connected, the alternate third in unison, the teeth of which are so arranged with the stroke or crank motion as to bring them directly over an open slot made across the bottom V in their downward dip, while at certain intervals a hooked tooth is inserted, to hold the straw and aid in more effectually shaking out the grains that may be entangled therein.
Pshows alarge driving-pulley on the lower crank-shaft.
R is a triangular cam-pulley, with rounded corners, to operate the rod S, held in a pivot on the trough or side T, and secured by a joint in the plate fw on lower bottom, U, and vibrates the same. On the opposite side ofthe machine, Fig. 5, I also use a horizontal shaft, a', geared by a bevel cog-wheel, Z, to one, Y, 011 the end ofthe fan-shaft. vided with cams p, of a peculiar rounded quadrangular shape, and hinged spring-beaters r, connecting with the shoe and Screen inside,
This horizontal shaft is prof the arrangement of whiehprcduce remarkable results by their harmony of action; but I confine my claim to the device for regulating the blast. This consists of a lever-arm, F, with teeth g, :for a sliding weight, G,.and a longitudinal slot, 7L, for the rod II on the hanging frame I. This lever F has also a bearing, j', for the fan-shaft M, and terminated by a pivotbearing, by which it is held in the bracketarm N, fastened below to the bed-beam A, so that when the lever-armis moved upward the fan-shaft is slightly raised, thereby slackening the belt C, which connects the fan-pulley B with the pulley D on the shaft of the spiked cylinder or thrasher. The same weighted lever, operated in like manner, but connected with a hanging`pulley so arranged as to press against the belt to increase the speed, I have also tried; (the bearing of the fan-shaft in that case was stationary,) but, after trial, find the arrangement shown to be the most satisfactory.
The swinging frame I I, with its cross-strips K, is balanced centrally above the fan-shaft M in bearings E. The fan L revolves between this swinging frame, and when driven with excess of speed will cause the frame I to raise on the inner side, and, being connected with the slotted lever-arm F by the connecting-rod H, will actuate the lever and slacken the belt in the manner before stated. The sliding weight on the lever-arm is to adjust the tension of the bolt and regulate the' degree of the current or speed of the fan to a certain fixed standard, to which the fan is held by the counterpoise adapted to the required speed.
I am aware that various devices are employed to regulate the action of thefan in separators; but Iv am not aware that a weighted .lever calculated to tighten or slacken the belt which connects the cylinder and fan-pulleys was ever before used for that purpose, therefore,
Vhat I claim as my invention, and desire to secure by Letters Patent, is'- The slotted lever-arm F, with its sliding weight G, in combination with the swinging frame I K, with its connecting-rod I-I, for the purpose of acting upon the belt e, which actuates the fan-pulley B, for the purpose of regun lating the speed of the fan, substantiallyin the manner and for thepurpose Specified.
