Specification of Letters Patent.

Patented Mar. 8, 1921.

Application led August 6, 1920. Serial No. 401,613.

To all 'whom t may concern.'

Be it known that I, JOSEPH STYRBINSKI, a citizen of the United States of America, re-

siding at Michigan City, in the county of,

for its primary object to provide an ash sifter embodying an inclosing casing with a vibratory sifting screen suspended therein.

A further object of the invention aims to provide in-an ash sifter, a casing having a vibratory frame with a sifter screen supported thereon and operable eXteriorly of the casing, a removable tray being slidably associated with the bottom of the sifter casing for removing the screened ashes therefrom.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the appended claim.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views,

Figure 1 is a side elevational View of an ash sifter casing constructed in accordance with the present invention,

Fig. 2 is a top pla-n view of the same with the cover removed, and partially broken away to show the sifter screen mounted upon the vibratory frame within the casing and the operating arm for the frame,

Fig. 3 is a vertical cross sectional view taken on line III-III of Fig. 1, showing` the ash receptacle at the lower end of they casing.

Fig. 4 is a fragmentary sectional view showing the vibratory screen-supporting frame, and

Fig. 5 is a detail fragmentary perspective view of a portion of the screen-supporting vibratory frame.

Referring more in detail to the accompanying drawings there is illustrated an ash sifter embodying a casing having side walls 1 and 2 and end walls 3 and4 carried by the bottom wall 5 supported on corner legs 6, the upper end of the casing being provided with a cover 7, hinged as at 8 to the side wall 2 and carrying an ordinary hasp 9 at the free end thereof for engagement with the side wall 1 of the casing, the cover being more clearly shown in Figs. 1 and 3.

As shown in Figs. 1 and 2, lifting handles 10 are carried by the end walls 3 and 4. A vibratory screen-supporting frame is suspended within the casing and includes side strips 11 secured by the rivets 12 to the upper edges of the side walls 1 and 2 as shown in Figs. 3 and 4 and positioned beneath the inwardly-bent upper edges 13 of the side walls. The strip 11 adjacent each end thereof is bent upon itself 'to provide a U-shaped bracket 14 in which is secured the upper end of a resilient hanger strip 15, a mounting strip 11 being positioned on each side wall of the casing with the lower ends of the resilient hanger strips 15 connected to the angle ends 16 of the transverse bars 17, thus forming a rigid connection between oppositely-positioned hanger strips. As shown in Fig. 4, a longitudinal supporting strip 18 connects the transverse bars 17, the strips being secured thereto as at 19. A rectangular frame 20 has the lower edge thereof inwardly-flanged and is attached as at 21 to the supporting strips 18 to provide a supporting frame for the sifter screen. A sifter screen 22 is of rectangular formation as shown in Figs. 2 and 3 and has a reticulated bottom wall 23 with the entire screen memhandle 31 is positioned in the lower end of.

the casing and is adapted to be removed therefrom to dispose the ashes and other refuse sifted from the screen and received therein.

Assuming that the sifter screen 22 is filled with material to be sifted, such as ashes, with the cover 7 closed in the position shown in Figs. l and 3, theV handle 27 shifts the arm 24 upon the pivot 25 to reciprocate the vibratory frame suspended by the resilient strips l5, the strips 15 vibrating and carrying therethrough the frame 20 which supports the sifter screen 22 and a single movement of the handle 27 will communicate a series of continuous vibratory movements to the sifter screen within the casing, it is believed that the constructionand operation will at once become apparent, it being noted that the resiliency of the strips 15 provides for continuous successive vibratory movements in response to the operation of the handle 27.

While the form of the invention herein shown and described, is what is believed to be the preferred embodiment thereof, it is nevertheless to be understood that variousforms, modifications and arrangements of the parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, nwhat l claim as new and desire to secure by Letters Patent, is

An ash sifter of the type described comprising a casing, a side strip secured to each side of the casing adjacent the upper edges thereof, each strip being bent outwardly adjacent the ends thereof to provide brackets, flat resilient strips having the upper ends thereof secured in the strip brackets with the major transverse axes thereof extending transversely of the casing, a transverse bar rigidly connecting the lower ends of the resilient strips and spaced from the sides and ends of the casing, longitudinal strips secured to the transverse bars and projecting outwardlypof, the same, a rectangular frame secured to the ends of the longitudinal strips, a sifter screen supported on the longitudinal strips within the rectangular frame, an arm projecting outwardly from one of the transverse bars, and a handle lever pivoted in a side wall of the casing and with the inner end thereof connected to the free end of the arm for vibrating the sifter screen supporting frame.

In testimony whereof I affix my signature.

JOSEPH STYRBINSKI.
