ATTHNEYS UNITED sTATEs PATENT oEEIoE.
WILLIAM FRANKLIN sIvIITHDEAL, or s-ALIsBUnY, NORTH' cAnoLINA.
CHUR/N.
To all whom it may concern:
Be it lrnown that I, WILLIAM FRANKLIN SMITHDEAL, a citizen of the United States, and a resident of Salisbury, in the county of Rowan and State-of North Carolina, have invented a new and Improved Churn, of which the following is a full, clear, and exact description.
The invention is an improvement in churns, and has in view a comparatively simple and inexpensive construction which may be shipped or stowed in knock-down form andL easily set up for use without particular skill.
The invention in general may be defined as consisting of a pyramidal frame having head-blocks spaced apart, the head-blocks having slots in vertical alinement ent-ering the ed es from one side of the frame, a handlever ulcrumed at the opposite side ofthe frame and having a cross-arm, a dasher shaft removably journaled in the slots and having a belt wheel, and a belt detachably connected to the crossarm and passing around t-he wheel.
Reference is'to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indica-te corresponding parts in all the views.
Figure 1 is a front elevation of a churn constructed in accordance with my invention; Fig. 2 is a side elevation of the same; Fig. 3 is a plan of the churn; and Figlf is an upper edge view of the cross-arm and connected parts.
The frame of the churn for supporting Vthe several operating parts is preferably constructed in pyramidal form to insure stren th and stability, the frame consisting of a ase 5,' spaced head- blocks 6, 6 elevated a substantial distance above the base, and downwardly and outwardly-inclined stand-- ards 7 supporting the head-blocks from the base and arranged at the corners of the frame. The head-blocks have slots 8 in approximate vertical alinement, the slots enter- Ing the edges of the blocks from one side of the frame and terminating a substantial distance from the opposite side of the frame. Removably journaled in these slots is a dasher operating shaft 9 having a belt wheel Specification of Letters Patent.
Application led April 30, 1909.
Patented May 3, 1910.
Serial No. 493,123.
10 fixed thereto intermediate the length of the shaft, and a socket 11 fixed to the lower end of the shaft, the socket having a vertical slot 12 entering its bottom edge, which is for the purpose of engaging a key 13 carried by the dasher stem and locking the stem and shaft against relative rotation. When the shaft 9 is operatively placed in the slots 8, the belt wheel 10 is arranged between the blocks 6 and bears on the upper face of the lower block and thus supports the shaft in place. In order that the friction between the block and the ends of the belt wheel 10 may be greatly reduced, the ends of the block are rounded, as clearly shown in Figs. 1 and 2.
At that side of the churn frame opposite the slots 8, two levers 14, spaced apart, are fulcrulned to the base 5, and at the height of the belt wheel are provided with a crossarm 15, the cross-arm being fulcrumed to the levers in order that the latter may be freely swung back and forth in operating the churn. The ends of the cross-arms have projecting pins 16, to which is detachably connected a belt 17 passing around and crossing at the pulley, this arrangement of the levers, belt, etc. obviously drawing the dasher operating shaft to the inner ends of the slots and thus maintaining the shaft in proper operative position during the operation of the churn. The levers as they are oscillated are guided and held outwardly from the belt wheel by a guide-bar 18, ex-
tending crosswise and secured to the adjacent standards 7 The several parts of thefrarne and handlevers, etc. are detachably connected by screws or other suitable devices, which enables the entire churn to be packed in a small space for shipment and stowage and easily set up for use without requiring particular skill. y
I-Iaving thus described my invention, I claim as new and desire to secure by Letters Patent:
The combination in a churn, of an open pyramidal churn frame adapted to inclose the churn receptacle and having headblocks, a vert-ical dasher operating shaft removably journaled in the head-blocks and having a belt-wheel arranged therebetween, an operating lever fulcrumed at its inner end to the frame and projecting upwardly In testimony whereof I have signed my at one side thereof, a oross-bar attached to name t0 this specification in the presence of the lever, and a guide for the lever arranged two subscribing Witnesses.
on one side of the frame, a bet passmg WILLIAM FRANKLIN SMITHDEAL, about the pulley and connected to the olpp'o- Witnesses:
site ends of the cross-bar, drawing the ever W. T. KLUTTZ,
to the guide. WILLIAM BRITTINGHAM SMOOT.
