POVER-TRANSMITTING DE VICE FOR WASHING-MACHINES.
Specification of Letters Patent.
Patented Feb. 16, 1909.
-App1ica.tion filed March 16, 1907. Serial No. 362,735.
To all whom it may concern: 7
Be it knownthat I TnoMAs J. \VINANs, a citizen of the United States, residing at Bingh-amton, in-the county of Broome' and State of New York, have invented a'new anduseful Power-Transmitting Device l'or "ashiri'gddachines, of which the following is a specification.
This invention relates to power-trans- 'mitting devices employed in the conversion reciprocatory or oscillatory moprovide a connecting rod ol' 'tl1is character to permit the oscillatory member to cushion upon momentum absorbing springs, the yielding of which would depend upon the weight and velocity of said oscillatory memher, but causing said connecting rod to I shorten or lengthen without a prejudicial effect upon the el licien'cy ol the rotary driving member, because there is no reversal of the stress on the spring in said connecting rod while doing so- A still further ob'ect of the invention to provide a novel orm of cushioning con necting rod which may be readily adjusted for the purpose oi increasing or decreasing the cushioning cll ccts, or to compensate for fatigue oi the cushioning spring or springs.
With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangenn-nt of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details-of the structure may be made without do art- -'in from the spirit or sacrificing any the ac vantages of the invention.
In the accompanying drawingsz-Figure 1 is an elevation, part1 in section, of a portion of a washing mac line rovided with a connecting rod embodying t e invention.
Fig. 2 is a. plan view of the same, the tub being removed. Fig. 3 1s a sectional elevation of the connecting rod. Fig. 4 is a trans- 5 verse sectional view of the same. Fig. 5 is a view showing the various parts ol' the rod detached.
Similar numerals ol' rcl'crrncc arc em ployed to indicate corresponding parts throughout the several figures of the drawings.
i igs. 1 and of the drawings show the application of the invention to a washing machine, wherein designates the tub or clothes container, that is mounted on a spider 11, the latter including'a numlzer of arms which are carried by a frame 1'. rigidly secured to a central supporting shaft 1;), Whiehis free to oscillate in suitable hearings formed in a frame Ll. The tub or clothes container is arranged to swing in a horizontal plane, and if it contains a large quantity of and detergent, there is lifiely to he considerable strain on tho motoi mechanism in reversing the direction of movement at the completion of each sll'olitfi.
hi the present instance the apparatus is iarrangcd to be operated through or from a vertically disposed shalt 16 which is conncctcd to and may be driven from any suitablc source of )ower, for instance, a small water motor. ht the lower end of this shaft is a crank 17 which is connected to the l'raine 12 by the rod which forms the subject of the present invention, the frame .12 being providod with a laterally projecting lug 1S having an opening for the reception of the end of the rod. sections, the two principal parts of which comprisc a pair of U shaped .mis 2t) and 21. These are of the same size and length and intorlit, that. is to say, the cross bar of each his in the space between the two arms of the other, and the common plane of one set of arms is at a right angle to the similar plane 01' the other set of arms. The cross bar 01 each of these arms is provided with a threaded opening for the reception of a small rod 22, each rod having an upturned end ortion, one to engage in the opening of the ass 18, and the other to engage a corresponding opening in the crank 17. Extending outward from the ends of the arms of bar 20 are lugs 2% and similar lugs reject from the arms of the other bar. T iese ugs form opposite end bearings for a helical compression spring 26, and the ends of said clothes and a corresponding amount of water responding rod of the bar 21.
spring bear also against small cross bars extend carried by the small spring 3 against the spring is compressed when tensile or 2.ll+50, one of which is rod 22 of bar 20, and the other by the eel- As a result of eraser beyond the sides thereof, and a mounted upon both bars and seated said lugs and projections, whereby this construction, any movement imparted compressive stress is exerted on the ends. of
from either end'of the connecting red as a whole will result in compression of the spring: whether that force he exerted in one direction or the other,-ior instance, it in rig. 3 force is applied from the crank in the direction of the arrown, the block 30 would act against the end of the spring and tend to press the same against the block 29 of the 1S resistance to the.
. beyond, and a spring mountc upon both her 20, so that if there movement, the spring will lie compressed, and the shock will Le gradually aLsor Led lielore the positive movement in the direction of the arrow a starts.
lar manner when the tub nears the limit of its movement in either direction, the spring will he compressed in 'one instance between the two blocks 30 29, and in the other letween the two lugs 25-34 and in this manner the motion of the tub will is gradually arrested, and the power thus stored will Le utilized as the spring naturally expands in the starting of the return movement, so that no shock or jar can occur, and the operation may he carried on noiselessly and without danger of brealzagc ol' the parts.
I claim:
1. A yicldable pitman comprising a pair of intcriitting Ushaped bars, the ommon plane of the two arms of one bar being at right angles to the similar plane of the arms of the 1 other bar, the terminal of each bar being provided with outwardly projecting lugs and the bent portion of each bar being provided with blocks transversely 1f the force is applied 1n the direction oithe arrow b, the lugs 1 against one end of the thereof arranged to I said pitman.
2. A yieldable pitrnan comprising a pair of interfitting U shaped bars, the common plane of the two arms of one bar being at right angles to the similar plane of the other bar, the terminals of each bar being provided with outwardly projecting lugs, auxiliary blocks.v
2 held at the bent portion of each bar to extend transversely thereacross and project therebars and seated against said lugs and blo lrs whereby the spring is (ompressed when ten sile or compressive stress is exerted on the ends of said pitman.
3. The combination in a washing machine, of anioscillalory member having an indeterminate arcuate movement, and a (onnccting rod for transmitting movement thereto, said rod including a pair oi interlitting U shaped bars, the common plane of the two arms ol' one bar being. at a right angle to the similar plane of the arms of the other bar, the terminals of each bar being provided with outwardly projecting lugs, auxiliary blosks arranged one at the end of eaoh bar, threaded rods passing through the bloehs and bars, and a spring mountedupon both bars and seated against said lugs and blo;:hs, whereby said spring is (ompressed on pushingor pulling strain exerted on the rod from either end in either direction.
In testimony" that-l claim the foregoing-as my own, I have hereto affixed my signature in the presence of two witnesses.
