No. 391,149. Patenjned Oct. 16, 1888.
.7022: Miami? 95.13 x13 3 (l the M40130 UNITED STATES PATENT OFFICE SPECIFICATION forming part of Letters Patent No. 391,149, dated October 16, 1888.
Application filed April 25, 1888.
T0 aZZ whom it may concern.-
Be it known that I, JOHN M. HUNT, a citizen of the United States, residing at Cedar Town, in the county of Polk and State of Georgia, have invented a new and useful Improvement in Chorus, of which the following is a specification.
My invention relates to improvements in that class of reciprocating churns which employ rotating gear-wheels to impart motion to the dasher-rod, the rotary motion of said wheels being converted into a reciprocating motion by means of a crank-pin and crosshead; and it consists in certain novel features hereinafter first fully described,and then specitieally pointed out in the claim.
In the drawings, Figure 1 is a perspective view ofa churn provided with my improvements. Fig. 2 is an edge view with the churnbody removed. Fig. 3 is a detail view showing the crosshead and the crank-disk in perspective.
Referring to the drawings particularly by letter, A designates the base, of any desired size and of any suitable material. Upon the base, near one edge of the same, I erect the standard B, having its upper portion bent slightly toward the front, forming the elongated recess D, and provided with the integral forwardly-projecting arms 0 O on its front side near its center and at its top end. These arms 0 O are provided in their outer ends with vertical perforations or apertures, through which the reciprocating rod carrying the cross head works and by which it is guided. A bar, E, similar in construction to the upper portion of the standard, is bolted to the rear side of the same, a vertical space, F, being thereby provided in which the driving-gearing is ar ranged. This driving-gearing is consequently supported entirely by a single standard, and is arranged very compactly, besides being protected by the bar E and the upper portion of the standard. The said gearing consists of a horizontal shaft, K, journaled in the bar E and the upper portion of the standard at about the centers ofthesame, and projecting through and in front of the standard, a gear-pinion, J, and a balance or fl y wheel, L, being mounted on the said shaft between the standard and Serial No. 271,761. (No model.)
the bar E. The pinion J is in engagement with a gearwvlieel, G, mounted on the inner end ofa short driving-shaft, provided with a crank-handle, I, on its outer end and journaled in the bar E between the center and top of the same.
A crank-disk, M, is secured to the front end of the shaft K, and is provided on its front face near its circumference with a forwardlyprojecting crank-pin, N, which is surrounded by a collar or roller, 0, by which the friction and wear between the contacting parts is reduced to a minimum.
Q designates the cross-head, secured to the reciprocating rod R, mounted in the arms 0 of the standard, as shown. The cross-head is provided in its rear side with a groove, P, which is engaged by the crank-pin and in which said pin plays, the front side and the top, bottom, and ends of the cross-head being closed, so as to entirely cover the crank-pin, and thereby prevent access of grit and dirt thereto, which would accumulate in the cross head and tend to clog the same and consequently render the operation of the device difficult and uncertain, besides increasing the wear of the parts. A U-shaped yoke, S, is adjustably secured to the reciprocating rod above the cross head by means of a set-screw, s, and the dasher-rod T is mounted in the ends of the forwardly-projecting arms of the yoke, as shown. 'By means of the set-screw s the yoke can be quickly and accurately adjusted to the height of the churn-body, and the dasher-rod is adjustably secured in the arms of the yoke, so that the dashers U can be accommodated to the quantity of cream in the churn-body, and these adjustments may be effected either independently or together.
It will be readily seen from the foregoing description that I have provided a very compact, simple, and efficient churn, which is easy and light in its operation, and which can be quickly and easily adjusted to effectively operate with churn-bodies of various heights.
I am aware that crossheads and crank-disks have been heretofore employed in. churns and that dasherrods have been adjustably supported, but I make no broad claims to these features.
Having thus described my invention, I claim- 1 As an improvement in churns, the combination of the standard having the integral forwardly-projecting arms 0 G on its front side, the bar E,bolted to the rear side of the upper portion of the standard, a space, F, beingleft between said bar and standard to receive the driving gearing, the shaft K, projecting through and in front of the standard, the crank-disk mounted on the front end of said shaft, the crank-pin on said disk, the roller surrounding said pin, the reciprocating rod mounted in the arms 0 O, the cross-head secured to the said rod and having a groove in its rear side engaged by the crank-pin and its JOHN M. HUNT.
