BRAKE.

Specification of Letters Patent.

Patented May 8, 1917.

Application filed April 28, 1914. Serial No. 835,013.

To all whom it may concern:

Be it known that I, GLENN SMrrn, a subject of the King of Great Britain, residing at Youngs Cove, in the Province of New Brunswick and Dominion of Canada, have invented new and useful Improvements in Brakes, of which the following is a specification.

This invention relates to the type of churns in which the body is mounted to have a movement imparted thereto, the operating means being a motor of the spring variety.

The invention relates more particularly to the means whereby the churn body is supported and operated, the driving mechanism being controlled by means of a brake which may be set to hold the churn body stationary or to admit of it receiving a comparatively fast or slow movement.

The invention consists of the novel features, details of construction and combination of parts, which hereinafter will be more particularly set forth, illustrated in the accompanying drawing, and pointed out in the appended claim.

Referring to the drawing, forming a part of the specification,

Figure 1 is a front view of a churn embodying the invention.

Fig. 2 is a detail view of the churn power.

Fig. 3 is a detail view of the brake mechanism.

Corresponding and like parts are referred to in the following description, and indicated in all the views of the drawing, by the same reference characters.

The churn body 1 may be of any construc tion or shape and is mounted to have a rotary movement imparted thereto. The supporting frame comprises a base 2 and uprights 3 and 4C. Trunnions 5 and 6 project from opposite sides of the churn body and are mounted in the uprights 3 and 4. The churn power is mounted upon one of the uprights and the brake mechanism upon the other upright, thereby distributing the parts.

The churn power is contained within a case 7, which is secured to the outer side of the upright 3. A gear wheel 8 is secured to the outer end of the trunnion 5 and forms an element of a train of gearing by means of which motion is imparted to the churn body from a motor spring 9 mounted upon a shaft 10 to which a crank 11 fitted. It is to be understood that a ratchet connection is provided to enable the winding of the motor spring.

A wheel 11 is secured to the outer end of the trunnion G and is adapted to be engaged by a shoe 12 carried by a set screw 13 mounted in a bracket 14: attached to the upright 4:. The speed of the churn may be regulated by proper adjustment of the set screw 13 to cause the shoe 1? to engage the wheel 11 with a greater or less pressure. By turning the set screw 13 to cause the shoe 12 to bear hard against the wheel 11 the churn may be held stationary, which is desirable when filling or emptying the same.

From the foregoing description, ta, en in connection with the accompanying drawing, the advantages of the construction and the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which i now consider to be the best embooimeut thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when de sired as are within the scope of the claim. appended hereto.

Having thus described the invention what is claimed as new, is

In a device of the kind describes, in combination a standard, including a pair of upright bars, pintles mounted in said bars, a rotatable body supported upon saic pintles between said bars, a brake wheel mounted upon one of said pintles, a bracket secured to one of said bars beneath said wheel, a brake shoe having a boss formed therebelow, a threaded bolt passing through said bracket and having a swiveling support in thd boss of said shoe, a wing head formed upon said threaded bolt, and a lock nut threaded onto said bolt and adapted to engage said bracket, said brake shoe being arcuate andof a greater length than said boss.

In testimony whereof T affix my signature in presence of two witnesses.

GLENN SMITH.
