SPECIFIGATIONforming part of Letters Patent No. 522,522, dated July 3, 1894.

Application filed March 15, 1894- Serlal No. 503,718. (No model.)

v To all whom it may concern.-

Be it known that I, LEVI HERTZLER, a citizen of the United States of America, residing at 'Mechanicsburg, in the county of Cumberland and State of Pennsylvania, have invented certain new and useful Improvements in R- tary Bolts for Flour, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relatesto certain new and useful improvements in bolting reels for flour, the following being such a full, clear and exact description as will enable others skilled in the art to which it appertains to make and use the same. i

The object of the invention is to provide in bolting reels for flour means for automatically cleaning the screens employed, thereby increasing the capacity and efficiency of said ree s. 1

A further object of the invention is the provision of novel means whereby screens may be fixedly secured or released at the will of the operator; in which lattervcondition the said screen will fall and cause the stock which has collected in the meshes of the cloth toj'ar loose and fall out. p

A further object of my invention is the production of a device which will possess advantages in strength and durability and at the same time be simple of construction, efficient and satisfactory in use and comparatively inexpensive of manufacture.

The invention further consists in the pecu:

ence is had to the accompanying drawings forming part of this specification, andwherein like characters of reference indicate corresponding parts in the several views,-of which- Figure 1, is an end view of a bolting reel with the head removed and with the lockin g levers for securing the screens omitted. Fig. 2, is a perspective view of the same with the outer cloth removed. Fig. 3, isa vertical sectional view of one of the ribs.

In the drawings, 1, denotes the shaft of an ordinary bolting reel provided with the series of radial projections 2, 2, to which are secured ribs 3, forming the frame Work of the reel. The ribs 3 are provided with abevel 4 allowing'a portion of the stock to drop on the as cending side of the cloth, thereby producing a more uniform distribution of the stock on the cloth.

The screens 5 are secured tothe shaft 1, in any suitable manner and are bound at 6 to prevent fraying of the same; the whole screen being supported on the radial projections and ribs heretofore described.

The rods 6 are bent to form projections 7, 7, which engage the screens as shown and retain it in position when desired. If the screens are to be released the angular projections 8 of the rod should be sprung on the opposite side of the securing 'pin 9 when front movement will be allowed, while the securing of the screen again can be readily accomplished as will be: obvious. These rods are secured nal ribs provided with beveled rear faces, the

screens attached to the shaft and detachably secured at the outer end substantially as and for the purpose specified.

2. A bolting reel provided with a shaft, ra-

dial projections and longitudinal ribs with beveled rear faces, and screens, in combination with the rods by which the screens are detachably secured to the ribs for the purpose described. 7

In testimony whereof I affix mysignature in presence of two witnesses.

LEVI HERTZLER.
