FLOUR-SIFTER.

SPECIFICATION forming part of Letters Patent No. 553,845, dated February 4, 1896. Application ned nach 15, 1895. serial No. 541,868. or@ model.)

To' aZZ whom' t may concern:

Be it known that I, CARL P. EICHLER, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented certain new and useful Improvements in Flour-Sitters, of which the following is a specification7 the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle so as to distinguish it from other inventions.

The annexed drawings and the following description set forth in detail one mechanical form embodying the invention, such detail construction being but one of various inechanical forms in which the principle of the invention may be used. j

In said annexed drawings, vFigure I represents an axial section of my improved i'loursifter, and Fig. II a top plan view.

The body A of the sifter is of the usual cylindrical form, having the usual sloping upper edge, to give it the form of a scoop, and provided with the usual screen-bottom A. A handle-bail B, preferably formed from a strip of sheety metal, is secured with its ends to the low side of the body. An open-work stirrer C rests upon the screen-bottom and has preferably a substantially circular outline. Said stirrer may be formed from wire bent into serpentine or other open-work form, or it may be, as illustrated in the drawings, formed from a sheet-metal disk, cut out into the form of a grate or other reticulate pattern. The stirrer is held in contact with the bottom and is guided to have straight-line movement over said bottom by a rod C having sliding bearing for its ends in the sides of the sifter-K body, and to which the stirrer is soldered or otherwise secured. That end of the rod which projects into the lower end of the handlebail has a stop which is formed by the rod being bent at a right angle to form an open hook o. A movable handle D is yieldingly supported bya spring-coil d at its upper end in the upper end of the handle-bail, and has a pin d at its lower end, preferably formed by the end of the wire which forms the springcoil and which passes through the handle, which pin engages the hook of the stirrer-rod. A spring E is provided Within the sifter-body and is connected to the stirrer-rod to return the stirrer after it has been drawn toward the low side of the body by drawing the movable handle toward the handle-bail. An upward projection c is formed upon the stirrer-rod within the sitter-body and may be engaged by arms f radiating from a shaft F, which is transverselyjournaled in the sitter-body and is provided with a crank f for revolving it. By revolving the crank-shaft the arms will be caused to strike the projection upon the stirrer-rod so as to force it back against the spring, which will again force the rod and stirrer forward when the engaging arm slips off from the projection, whereby the stirrer will thus be reciprocated.

The open hook at the end of the stirrer-rod will admit of the stirrer being reciprocated without moving the movable handle, which is generally grasped together with the handle-bail when the sifter is in use.

The sifter can, on account of the provision Of the movable handle within the handle-bail, and the crank-'shaft7 be either held and actuated by 'one hand, or be held by one hand and actuated by the other, according to the convenience of the person using the sifter.

The above-described sifter is one form of improvement and addition to the style of sifter disclosed and claimed in United States Patent No. 513,489, for a flour-sifter, granted to me on the 30th day of January, 1894. In United States Patent No. 524, 892, for a sifter, granted to me on the 21st. day of August, 1894, I employed the movable handle disclosed in the former patent for the purpose of rotating a stirrer which was provided with an independent crank-shaft for rotating it, so that the sifter might be operated by the one hand grasping the handle-bail, by reciprocating the movable handle, or might be held by one hand grasping the handle-bail while the stirrer was rotated by turning the crank-shaft with the other hand. In the present form of sifter, forming the subject-matter of this application, the stirrer is reciprocated by either reciprocating the movable handle or by revolving the crank-shaft. Quicker and more effective action of the sifter is accomplished by the stirrer being reciprocated and returned by a spring than by the stirrer being rotated, particularly as the stirrer is returned with a jar by the action of the spring.

IOO

Other modes of applying the principle of.' my invention may be employed for the mode herein explained. Change may therefore be made as regards the mechanism thus disclosed,provided the principles of construction set forth respectively in the follmving claims are employed.

I therefore particularly point out and distinctly claim as my inventionl. In a flour-sifter, the combination of a sitter-body, a reciprocating stirrer upon the screen-bottom of the body, a movable handle connected to said stirrer to move it in one direction and to admit of it being independentl7 moved, a spring for returning the stirrcr, and a shaft journaled in the sitter-body and constructed to move the stirrer against the action of its spring when said shaft is revolved, substantialljv as set forth.

2. In a floursifter, the combination of a sifter-body; a movable handle; a reciproca ing stirrcr upon the screen-bottom of the body, provided with an open connection with the handle to adm it of the latter moving the stirrer in one direction and of permitting the stirrer to move independently, and provided with an upward projection g a spring connected to the stirrer to return it; and a rotary shaft inthe sifter-body provided with a cani which engages the projection of the stirrer, substanw tially as set forth.

In a flour-sitter, the combination of a sifter-body, a reciprocating stirrer upon the screen-bottom of the body and provided with a rod projecting through the side of the body and provided with a stop upon such projecting portion, a movable handle engaging said stop to reciprocate the stirrer in one (lirection and to admit of the stirrer being independentl);r moved, a spring connected to the stirrer to return it, and a sha-ft journaled in the body and constructed to reciprocate the stirrer against its spring when revolved, substan tially as set forth.

i. In a ilonr-sifter, the combination of a sifter-bodyv having a rigid. handle-bail, a reciprocating stirrer upon the screen-betteln of the body and provided with an upward proj eetion and with a rod projecting through the body into the bail and there having an open hook, a movable spring-handle on the handlebail and having a pin engaging' said hook, a spring connected to return the stil-rer, and a crank-shaft journaled in the sitter-body and provided with a cam en gaging the s1 irrer projection, substantially set forth.

5. In a ilour-sifter, the combination of a siftcr-body having a rigid handle-bail, a movable spring-handle on said bail, a stirrer, areturning-spring for the same, a rod upon the stirrer projecting through the walls of the sitter-body and connected to the spring-handle and bent at its middle to form an upward projection, and a cam-shaft engaging such projection, substantially as set forth.

In testimony that I claim the foregoing to be my invention I have hereunto set my hand this 13th day of March, A. I). 1805.
