JOHN J. COFFEY, OF BROOKLYN, NEW YORK.

WASHBOARD.

Application filed August 24, 1315.

To all fui/tom t may concern Be it known that I, JOHN J. COFFEY, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Washboard, of which the following is a full, clear, and exact description.

This invention relates to washing' and scrubbing and has particular reference to the construction of wash boards.

Among the objects of the invention is to improve the construction of a wash 4board with respect to simplicity and strength of construction and its sanitary nature in practice.

With the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed herein, still for `the purpose of illustrating a practical embodiment thereof reference .is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which- Figure 1 is a front elevation of a preferred embodiment of the invention one corner being broken away; Fig. 2 is a vertical section on theline 2--2 of Fig. 1; Fig. 3 is a transverse sectional detail of the line 3 3 of Fig. 1; Fig. 4 is a perspective detail of the rubbing surface shown in Fig. 1; and Fig. 5 is a similar view of a modified form.

Referring more particularly to drawings, I show a wash board construction compris ing a frame composed of wood or other suitable rigid material and including side rails 10, a top rail 11, and a plurality of stiffening rods 12 and 13, extending transversely between the side rails. I prefer to use two of the bars 12 arranged in the same horizontal plane just below the top of the frame and in front of and at the rear of the central plane of the structure. These bars 12 therefore, serve not only as stiifeners or reinforcement means for the frame but also as temporary holders for the bar of soap or the like in practice.

The side rails and the top rail are rabbeted or grooved at 10 and 11 respectively for the reception of the body portion of the device, said body comprising a ller 14 consisting of a sheet of wood or its equivalent extending ,laterally into the rabbets 10 and 11 and faced front and rear with a double Speccation of Letters Patent.

rubbing surface of sheet metal or its equivalent and including a. front face 15 and a rear faceklG connected by a loop 17 embracing the rod 13 where the face plate passes around the lower edge of the filler. At the sides and top the rubbing surface is co-extensive with the filler and hence projects into the rabbets aforesaid on both sides of the filler making a close snug neat fit in the side and top rails, such connection being made secure and permanent by the rods 12 and 13.

The front rubbing face'l comprises a corrugated portion 15a, side flanges 15b and a smooth upper panel 15C, spaced rearwardly from one of the rods 12. As indicated in Figs. 1 and 4 the corrugations 15a are of isosceles triangular form in cross-section with the ends thereof beveled off as shown at 18. rlhe margins 151 are wide enough to allow considerable clearance between the beveled ends 18 and the side rails allowing free drainage space forthe suds, and since the rubbing surface is fitted snugly in the rabbets 10 and no sharp corners are left at the ends of the corrugations there is no place for the collection and retention of lint, dirt or the like. The back face 16 also is corrugated and may be formed of the corrugated part and also the smooth panels 16b and 16c the same as the front face. A loop 17 makes a strong and smooth connection embracing the bar 13.

In the modification of Fig. 5 the rubbing surface is constructed of a continuous piece of sheet metal or its equivalent, including triangular corrugations 20, a smooth Side margin 21 and a forwardly projecting semicylindrical bead 22. The margin 21 is wide enough to insure a clear space between the bead and the side rail adjacent' thereto."

p from said rods, the corrugations of the rubhing surfaces having their ends clear of name to this specification in the presence of and spaced laterally from th) side rails, two subscribing witnesses. there being a semi-cylindrical ead formed along the ends of the corrugations and of a JOHN J' COFFEY' 5 depth substantially equal to the altitude of Witnesses:

the corrugations. ARTHUR LITTMAN, In testimony whereof I have signed my SGNNE P. MENKE.
