ETHELYN E. COLE, OF BENTON, WASHINGTON.

FLOUR SIFTER.

Application filed June 22, 1923.

To all whom it may concern:

Be it known that 1 ETHELYN E. COLE, a citizen of the United States, residing at Benton, in the county of King and Stateof \Vashington, have invented new and useful Improvements in Flour Sifters, of which the following is a specification.

This invention relates to kitchen apparatus, particularly to sitters, and has for its object the provision of a novel sifter for mixing and sifting the flour and other dry ingredients used in baking.

An important object is the provision of a sifter of this character in which the sifting action is accomplished merely by shaking the device back and forth in the hand,

rubbers being provided upon each side of the sifting screen.

Another object is the provision of a device of this character which has its body portion provided with detachable caps or cups which will enable the dry ingredients to be run through the device repeatedly without it being necessary to deposit the ingredients in an auxiliary receptacle, the device in this way effecting a great saving in time, labor and materials.

An additional object is the provision of a sifter of this character which will be simple and inexpensive in manufacture, highly efficient in use, durable in service and a general improvement in the art.

With the above and other objects and advantages in view the invention consists in th details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:

Figure l is a side elevation of the complete device,

Figure 2 is a longitudinal section therethrough,

Figure 3 is a cross section,

Figure 4 is a detail perspective view of the pivoting bracket,

Figure 5 is an enlarged detail section showing the slidable closure plate,

Figure 6 is a detail elevation looking toward the sliding plate,

Figure 7 is a detail view illustrating the manner of formation of the guides for the sliding plate,

Figure 8 is a detail section showing the cover holding means and Figure 9 is a detail section showing the Serial No. 647,120.

manner of holding the screen within the shell or casing.

eferring more particularly to the drawings the numeral 10 designates the cylin drical body of the device which may be constructed of tin as is customary or any other suitable sheet material. The top of this receptacle is designed to be closed by a removable cap 11 held in place by means of a co-acting projection and groove 12 and 13 constituting a species of bayonet slot connection. The lower end of the body is preferably slightly reduced as indicated at 14 for engagement within the open end of a detachable cup 15 likewise held in place by a projection 16 and co-acrting groove 17. This cup 15 is formed with a series of ridges or grooves 18 which designate graduations so that the volume of flour or other dry material within the cup may be ascertained.

Located within the body is a sieve or screen 19 of suitable fineness having its edge bound with a metal binding 20 held within a slit groove 21 in the body. The binding might be omitted but it adds stiffness to the screen and is therefore preferably employed. Secured within the body against the inner wall thereof is a Ushaped bracket 22 riveted, soldered, or otherwise held in place, while at a diametrically opposite point the material of the body is slit as indicated at 23 and 24 and the edges of the slit are turned in and subsequently rebent to provide guide flanges 25 located at opposite sides of the resultant opening 26.

In connection wit-h the screen I provide a rubber structure formed preferably from a single length of wire twisted together at 27 intermediate its ends to define a handle 28 and two arms 29 located at opposite sides of the screen. The arm port-ions 29 are bent into serpentine shape as indicated in the cross sectional view to provide a relatively large effective rubbing surface, or to provide long lines of contact of the arms with the screen. The free ends of the arms are bent in opposite directions and rebent as indicated at 30 with their terminals 31 pivoted within suitable holes in the arms of the bracket 22. Adjacent the twisted portion 27, the arms 29 pass through a curved plate 82 which is slidable between the guide flanges 25 and which is of considerably greater length than the opening 26 so as to cover this opening at all times and prevent flour r other material from leaking out whenthe device is in use. The device is used by pouring the flour onto the sieve and shaking the device back and forth while holding itby the handle 28'. The rubber arms 29 rubbing against the sieve will eii ectually break up any lumps of flour or other dry ingredients and also commingle them properly. This is the ordinary uSe but the device isparticu-larly well adapted for the more important operation oi not only breaking up the lumpsbut mixing together the ingredients in those-instances where repeated sifting is necessary. In this case the cup 15- is' engaged uponthe bot-y, the dry materials are placed within the device, and engaging the cap 11 in place. When the device is then held upright and shaken all the material will be broken up and mixed by being torced through the screen. All the material will then be in the cup 15. The dev ce is then turned over and the operation repeated which willv bring all the materialagain through the screen untilit accumulates within the cap 11., after which inversion is then accomplished and the operation repeated in this way as many times as the recipe may call for. The advantage is that there is a great saving 0%? time and labor as well as in material as there is nothing lost by placing the material in any auxiliary receptacle. 7 From the foregoing description and a study of the drawings it will be apparent that I have thus provided a simply constructed and inexpensive sitter which will be highly efficient for all the purposes specified and which on account of its simplicity is not likelyto get out of order at any time,- ample provision is made for preventing leaking or loss of material from any source.

While I have shown and described the preferred embodiment of the invention it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from thespirit of the invention or the scope of the subjoined claims.

Having thus described my invention 1 claim;

1. In a flour sitter, a hollow body, a screen secured within and extending across the intermediate portion thereof, a U- shaped bracket secured against the inside of the wall and straddling said screen, the body being formed with an elongated lateral slot opposite said bracket, channeled gnides formed integrally with the body at the longitudinal edges of said slot, a curved plate slidable along said guides, and a rubbing member formed from a single length of wire and inchidling arms extending through said plate and arranged at opposite sides of the screen, each arm having its intermediate portion of serpentine tormation and terminating at its inner end in a hook, said hooks being oppositely arranged, directed toward the screen and pivotally engaged with the arms of said bracket.

2. A flour sitter comprising an elongated hollow cylindrical body, receptacles detachabl'y connected with the ends 01 the body, screen within the body, a pair oi? rubbing arms pivoted at one end within the body and located at opposite sides of the screen, said arms having their screen engaging pmti-ons termed serpentine, said body being formed with an elongated slot pern-iittinnlateral movement of the rubbing arms, and a plate carried by the arms and always covering said slot, said arms being both formed from a singlelength of wire having; its intermediate portion twisted to form a bandle and having its ends terminating in pivot extensions, and a bracket located within the body and with which said pivot ends are: engaged.

In testimony whereof I allix my signature.

lvllns. ETHELYN E. COLE.
