SlEVE-OPERATING DEVICE.
SPECIFICATION forming part of Letters PatentNo. 314,904, dated March 31, 1885.
Application filed December 17, 1884. (No model.) I
To all whom it may concern.-
Be it known that I, Brennan D. Yosr, a citizen of the United States, residing at Glencoe, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Sieve-Operating Devices, of which the following is a specification.
My invention relates to a device for operating an ordinary hand-sie've, such as is used for household and other purposes. The object is to provide a convenient device which will support the sieve and enable the desired shaking motion to be given it, thus obviating the necessity of taking the sieve, as usual, in the hand.
In the accompanying drawings, Figure 1 is a side view of a table-top to which the inn-- proved device is attached, supporting the sieve above the table-top. Fig. 2 is a top r plan view of the same. Fig. 8 is a view of the device, excepting the clamp by which it is attached to the table-top. Fig. 4. is a view of the cross-bar which supports the sieve. Fig. 5 is a view of the clamp and part of the device.
The letter A designates the top of a table; B, an ordinary dough-mixing board, such as is commonly used by pastry-cooks. The sieve O is supported by an arm, D, above the mixing-board. This arm has two shoulders, a, and carries a cross-bar, I), provided at its ends with similar shoulders, a, and at its center with a notch,'c, which sets astride of the arm and meshes with a similar'notch thereon. By this construction the cross-bar and arm are halved together, and all the shoulders at and a are equidistant from the point where the two are halved.
Any suitable means may be used to secure the cross-bar. In the present instance a wire, d, bent in the form of a ring, passes through both cross-bar and arm and fastens the two securely.
The cross-bar and arm having the shoulders or and a equidistant from the attachingpoint constitute a seat for the sieve O. Sieves of various sizes may set on this seat. The arm is supported by its end 6 being attached in any suitable manner to a pivoted hub, F. This hub has a round bore, which is occupied by a fixed upright stud or shaft, G. A setscrew, it, enteringthe side of the hub,impinges against the stud, and serves to make the hub rigid with respect thereto. The lower end of the stud is attached to a clamp plate, I, and made fast thereto, and the clamp-plate has two jaws, it, one of which takes over and the other under the table-top B. A set-screw, a, in one of the jaws serves to make the clampplate fast to the table-top. A spiral spring, 1), surrounds thestud G, and its lower end rests on top of the clamp-plate, while its upper end bears up against the hub F. This spiral spring serves to temporarily support the hub, arm, and sieve when the set screw h is loosened, and if it is desired to raise or lower the arm and sieve, as indicated by broken lines in Fig. 1, the spiral spring will react or yield for that purpose. As the hub is pivoted on the stud, the sieve-supporting arm D may turn around the stud for an axis in a horizontal plane. By loosening the set-screw h the arm may be moved to one side so as to change the position of the sieve, as indicated by broken lines in Fig. 2. By the arm or its hub beingloosely attached on the upright stud G, and made fast thereto by the set-screw h, the sieve may be turned either in ahorizontal plane or adjusted vertically.
In constructing the arm provision is made so that it will spring or yield laterally. To this end the arm at a point between the sieve and hub is made thin, as at q. By having this spring feature in the arm while its supported end is rigid, the sieve may be vibrated in a horizontal plane. The desired shaking motion therefore may be given the sieve while it is supported on the arm. The sieve,being supported above the dough-mixing board and containing flour, may be operated by striking it at the side with the hand, which will cause it to vibrate or shake.
It is obvious that certain features of the invention may vary from the construction here shown without impairing the operativeness of the others.
Having described myinvention, I claim and desire to secure by Letters Patent of the United States- 1. In a sieve-operating device, the combinaat one end with a seat for a sieve, as set forth. at one end with a seat for a sieve, and having 2. In asieve-operating device, the coinbinaits other end loosely attached to the upright 15 tion, with an upright stud, of an arm having stud, means for making the arm rigid on the 5 aportion ofits length made thin, so as to spring stud, and a spring, 19, about the stud hearing or vibrate in a horizontal plane, provided at up against the arm, as set forth.
or vibrate in a horizontal plane, and provided I device, of an upright stud, an arm provided I one end with a seat for a sieve, and looselyat- In testimony whereof I aifix my signature in tached at its other end to said upright stud, presence of two witnesses.
and means for making it rigid therewith, RICHARD D. YOST. 10 whereby it may be turned in a horizontal plane XVitnesses:
