V MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 281,939, dated July 24-, 1883. Application filed June '7, 1883. (No model.)

To all whom it may concern:

Be it known that I, O; F. STEDMAN, of Fre. donia, in the county of Chautauqua and State of New York, have invented certain new and usefulImprovementsinMechanicalllfovements for Operating Ohurns and \Vashing-lVIachines;

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being hadto the accompanying drawings, which form part of this specification.

My invention relates to an improvement in mechanical movements for operating churns and washing-machines; and it consists, first, inaweighted swinging pendant which has connected to its upper end an arm which is provided with means of attachment for the dasher of a clmrn or the pounder of a washing-machine; second, in the combination of the swing ing pendant, the frame in which it is pivoted, and an adjustable frame having springs at tached thereto for regulating the movement of the pendant; third, in the combination of a weighted swinging pendant, having an arm attached to its upper end, with a suitable spring, arm, or catch, which is secured upon the upper side of the frame, for holding the dasher of a churn or the pounder of a washing-machine, all of which will be more fully described hereinafter.

The object of any invention is to provide a mechanical movement which is especially adapted to be used where a reciprocating movement is required, as in churns and pounder washinganachines, and which is so constructed that it can be operated rapidly and easily.

Figurel is a vertical longitudinal section of a machine embodying myinvention. Fig. 2 is a plan viewof the same. Fig. 3is a rear view.

Arepresents the stand or frame upon which the tub or churn is to be placed. Rising upward from one end of this frame are the two standards B, between the upper ends of which is pivoted the swinging pendant or frame 0. This frame is secured by means of setscrews D and short rods or journals E, which pass outward through the upper ends of the frame C, washers F, and the upper ends of the standards B. Short hearings or journals are used, as here shown, for the purpose of allowing the swinging frame or pendant G to be removed from between the standards B whenever it is desired.

Pivoted to the upper ends of the two standards B, and reaching across their tops, is the holding-band or cross-piece G, which braces the standards together. Vhen it is desired to remove the swinging frame 0, it is only necessary to remove the set-screws and then force the short bearings or pivots inward, when the frame can be readily removed. To the upper end of this swinging frame or pendant O is rigidly secured the arm H, which projects outward any suitable distance, and which has a slot, 1, cut in its outer end, to allow the churndasher or clothes-pounder to be inserted therein. In order to connect this churn-dasher or clothes-pounder directly to the arm, there is secured upon its top a spring holding device, J, which consists of two spring-prongs, which are forced apart as the dasher or pounderrod is forced in between them. After the rod has been forced in between them they spring back and hold it, so that there is no danger of its be coming displaced.

Secured to the lower end of the swinging frame or pendant C is the weight L, which weight is secured to the frame or pendantGin such a manner as to project as far beyond it as possible in an outward direction. The manner of attaching the weight L to the pendants causes the pendants to swing inward,and thus cause the arm H to assume an angle upward. By means of this construction a much greater upward stroke is obtained. This weight, attached to the lower end of the swinging pendants, gives them a momentum, so as to cause them to vibrate back and forth, having once been started in motion, and thus make it much easier for the operator to keep them in motion. The weight also enables a harder stroke to be given with less exertion to the operator, who

' keeps the pendant 'in motion by means of the handle P.

In order to regulate the movement of the pendant and prevent its movement from jarring the standards, there is attached to the standards the two supports 0 for the springs Q. These supports have their ends bent at right angles, as shown, so as to catch over the outer or inner sides of the standards, and each of these ends is made slotted, as shown, so that these supports can be adjusted back and forth, for the purpose of bringing the coiled springs nearer to or farther from the swinging frame or pendant. The springs Q are secured to these supports just opposite the center of the pendants or frames, and as the pendant swings back and forth it alternately strikes the springs, compresses them, and then the recoil of the spring throws the pendant in the opposite direction. In this manner the motion, after it has been once started, can be readily and easily kept up for a much longer time than could be done were the springs not used. By adj usting the spring-supports, the length the weight- 2. The combination ofthe frame A, the stand ards B, the swinging pendants 0, having the arm H attached to their upper ends, and the weight L attached to their lower ends, the weight L being attached to the standards so as to project outward beyond them as far as pos sible, substantially as described.

3. The combination of the weighted swinging pendants, having the arm H attached to their upper ends, with the spring-catch J, which is secured upon the top of the arm, substantially as specified.

4. The combination of the standards, the weighted swinging pendants, having the arm H attached thereto, the spring-supports, and the springs, substantially as shown.

5. The combination of the frame A, the stand ards B, the swinging pendants, having a weight attached to their lower end, and the arm H to their-upper one, the spring-supports, and the springs, substantially as set forth.

Intestimony whereof I affix my signature in presence of two witnesses.

O. F. STEDMAN.
