Description

M. J. WALKER. GEAR CASING. APPLICATION FILED JAN.29, 1911.-
Patent ed Dec. 25, 1917.
Mann J. wnxna, or NEWCASTLE; WYOMING. V
' GEAR-CASING.
Specification of Letters Patent,
Application filed January 29, 1917. Serial No. 145,176.
To all whom it may concern:
Be it known that I, MAUD J. WALKER,-{L
citizen of the United States, residing at Newcastle, in the county of Weston, State of Wyoming, have invented certain new and useful Improvements in Gear-Casings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in gear casings and particularly to gear casings used on clothes wringers.
One object of the present invention is to provide a device of this character which can be quickly and easily applied to the or- -dinary wringer without any modifications to the wringer.
Another object is to provide a device of this character which will protect the clothes, as they pass between the rollers of the wringer, from catching in the gears, both from the inside and from the outside of the wringer.
Another object is to provide a simple cheap device of this character which is formed of a single piece of metal and includes the inwardly and outwardly protecting features, above-mentioned.
Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.
In the drawin Figure 1 is a front elevation of a portion of a clothes wringer showing my invention applied thereto.
Fig. 2 is a side elevation of the same.
Fig. 3 is a vertical sectional view taken on the line 3-3 of Fig. 2.
Fig. 4 is an enlarged plan view of the blank from which the gear casing is formed.
Referring particularly to the accompanying drawing, 10 represents a. portion of a clothes wringer frame, .and 11 the gears which drive the rollers 12. Mounted on the side of the frame 10 is a casing, represented as a whole by the reference character A, which covers the said gears to prevent the catching of the clothes therein as they pass between the rollers.
The casing is formed of a single piece of sheet metal, and includes a body portion 13, having a circular opening 14, through which the crank handle shaft 15 is arranged to project, when the casing is in proper position onthe wringer frame. At each end of the body there is formed a tab, represented respectively at 16 and 17, each having the sector-shaped wings 18 extending from the opposite sides thereof. Connected to the center of the outer longer edge of the tab 16, by means of the neck 19, is a plate portion 20, from the outer end of which there extends inwardly a longitudinal open-ended slot 21. This slot receives the before-mentioned shaft 15, as shown in the figures showing the application of the device to the wringer. The ends of the body are separated from the tabs 16 and 17 by the fold lines 24, while the sides of the body are separated from side tabs 22 and 23 by the fold lines 25. On each side of the neck 19, and connected to the end tab 16, are the perforated ears 26, which receive screws or other suitable fastening devices 27 for the purpose of attaching the casing to the frame of the wringer. The outer end of the tab 17 is formed with a flange 28 provided with perforations for the same purpose. When folded the plate portion is disposed in parallel relation with the body portion of the blank with its opening or slot in alinement with the circular opening of the body. The gears of the wringer will be disposed within the casing, the main or body portion effectively protecting the clothes from engagement with the gears from the outside of the wringer, while the plate portion, which is disposed between the gears and the frame of the wringer, will prevent the catching of the clothes, in the gears, from the inside.
The entire device is formed from a single blank of metal, and can be readily applied to the ordinary wringer without any modifications to the wringer. Furthermore, the casing can be easily applied by anyone Without mechanical skill or the use of special tools other than the ordinary screw driver. The fact that the device is made from one piece of sheet metal provides a device which can be stamped out in large quantities at a very low cost, and can be sold at a figure within reach of everyone.
WVhat is claimed is:
1. A gear casing for a clothes wringer comprising a housing arranged to be secured to the frame of the wringer and inclose the gears, said housing having a plate portion disposed between the housing and the wringer frame for preventing the engage- Patented Dec,
v ment of clothes passing through the rollers the body, laterally extending Wings on the tabs, a plate portion connected to the intermediate portion of one of the tabs by a neck,
plate portion being formed with an 10 elongated open-ended slot, and attaching means on the said tabs.
In testimony whereof, I aflix my signature; in the presence of tWo Witnesses.
