SPECIFICATION forming part 0f Letters Patent No. l744,444, dated November 17, 1903.
Application filed September 24, 19( )3. Serial No. 174,410. (No model.)
To all whom it may concern.-
Beit known that I, WILLIAM H. Voss, acitizen of the United States, residing'at Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Mechanical Movements; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which .form a part of this specification.
This invention relates to a novel mechanical movement designed to produce through the medium of a swinging actuating member alternate rotations or partial rotations of a shaft in opposite directions.
The mechanical movement herein illustrated is readily adaptable for operating the stirrer-blocks of washingmachines of that class wherein the block is rotated alternately in opposite directions to rub the clothes `against the interior walls of the suds-box of the machine; but the mechanism may be employed generally wherever it is desired to impart a like movement to a part of any other machine.
The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.
In the drawings, Figure l is a side elevation, with parts in section, of a washing-machine to which Amy novel mechanical movement is applied as the actuating mechanism foi` operating the stirrer-block. Figs. 2 and 3 are top plan views thereof, showing the parts of the actuating mechanism'in two different positions.
As shown in the drawings, A designates the suds-box of a washing-machine, and B the stirrer-block thereof. The shaft B of the stirrer-block extends upwardly through the removable cover or lid A of the suds-box and is rotatively mounted at its upper end in a bracket A2, rising from said lid or cover, and in a suitable sleeve A3, attached tothe upper side of said cover.
C designates a gear which is fixed to the stirrer-block shaft B just above the lid or cover A.
y D designates a horizontally-swinging actuating lever having a bearing-sleeve d at its inner end, which is rotatively mounted on the stirrer-block shaft between said gear C and the head of the bracket A2. Said actuatinglever is provided with a removable part or outer end D', whereby, while providing ample lever power, the parts may be compactly arranged for shipping and storing. y E designatesa gear which is located just beneath said swinging actuating-lever D, being rotatively mounted on a vertical pin or shaft CZ', extending downwardly from said lever, and said gear meshes with the gear C. Said gear E is herein Vshown as made of segmental form. Said segmental gearE is provided with a rearwardly-extending guide-arm E', which has guiding engagementwith a stationary part of the machine to which the mechanism is applied, the purpose of which is to impart a positive rotary movement to the gear E during the swing of the lever D, which rotary movement is in turn transmitted to the gear to rotate the shaft B. In the form of mechanism herein shown the guide-arm E is provided with a slot e, through which extends a guide-pin j", rising from a block or plate F, attached to the machine-cover A andl adapted to be fixed stationary to said cover.V Said pin f is preferably provided with an antifrictionroller f as shown in Fig. 1, thereby minimizing friction between the movable and stationary parts. The said block F, carrying the guide-pin f, is adapted to be adjusted toward and from the stirrer-block shaft B', and for this purpose the said block is provided with a longitudinal slot f2, through which extends the bolt f3, by which `the block is attached to the cover.
In the operation of the mechanism the lever D is swung horizontally from one limit of its movement to the other through the medium of the extension Dl thereof and in its swinging movement carries with it the gear E, which is in mesh with the gear-pinion C. By rea-1 son of the guiding engagement of the larm E' of said gear E with the pin f or other stationary part of the device such swinging movement of the lever D imparts a positive rotary motion to the gear E, which in turn rotates the gear C and connected shaft B. Inasmuch as the distance between the axes of rotation of the gea-rs C and E is a fixed one and inasmuch as the distance between the axis of rotation of said gear E and the guide-pin f varies in different parts of the swing of the actuating-lever D it will be observed that during the swing of the said lever D and while the gear E is being carried around the gear C in mesh therewith the gear E and its guidearm E' shift outwardly toward the guide-pin, which is permitted by the slotted connection of the arm with said guide pin or other analogous construction. In this manner the power applied to the lever D is transmitted through the gears E and C to turn or rotate the shaft B, and the direction of rotation of such shaft is reversed at each reversal of the swinging movement of the lever D. The lever D and the gear E, together with its guidearm E', constitute, with their connections, a compound lever, the fulcrum of the primary lever D being the shaft B', while the fulcrum of the secondary lever-to wit, the gear E and its arm E-is the guide-pinf. Said latter fulerum constantly changes during the swing of the lever D, owing to the shiftin g of the guidearm E relatively .to its guide-pin f. The length of the gear E is such relatively to the size of the gear C that said latter gear will be turned almost a complete rotation during each complete swing of the actuating-lever D. The relation of said gears may be varied, however, as desired in order to turn the shaft B more or less in each swing of the lever D.
The purpose of the adjustment of the guidepin f is to vary the amplitude of partial rotation or throw of the gear E and therefore vary the length of rotary movement of the shaft B in either or both directions. Thus it will be seen that if the pin f be adjusted toward the shaft B it will have the effect of lengthening the throw of the gear E, so that said gear and the gear C and shaft B will be rotated farther in each swing of the lever D. On the other hand, if the guide-pin be adj usted outwardly away from the shaft B' the gear will not be carried so far in each swing of the lever D, thereby limiting the length of rotation of the gear C and shaft B' for each swing of the lever D. It will be seen, therefore, that with a given relation or proportionment of the gears E and C various degrees of movement of the shaft B with respect to the length of rotation thereof may be provided. It will also be observed that, assuming the lever D be swung backward and forward at a uniform speed when the parts are adjusted for the longer throws of the gear E, the shaft B will be moved at a greater speed than when adjusted for the shorter throws of said gear E. The slot e of the guide-arm of the gear E is of such length as to be engaged at its ends by the guide-pin f at the ends of the throw of the parts, so as to prevent the gear E from getting out of mesh.
It will be understood that the form of the gear E may be varied while retaining the capability thereof of amplifying movement of the actuating-lever Z),which is imparted to the shaft B', and, furthermore, that the form of guide connection. between the gear-lever D and stationary part of the device, as the guide-pin f, may be varied.
