SOAP-FLAKER.

SPECIFICATION forming part of Letters Patent No. 739,175, dated September 15, 1903.

Application led May 22, 1903. Serial No. 158,324. (No model.)

To all whom it may concern/.f

Be it known that I, WILLIAM G. HAWLEY, a citizen of the United Statesof America, residing in NewYork city, county and State of New York, have invented an Improved'Soap- Flaker, of which the following is a specification.

This invention has for its object to improve the construction of soap liakers or shavers for lavatory use, so that they can be cheaply constructed, readily operated, be of sightly appearance, and be convenient for use.

In the accompanying drawings, Figure lis a sectional elevation on the line 1 1, Fig. 2. Fig. 2 is a sectional front view of the soapflaker on the line 2 2, Fig. 1. Fig. 3 is asection of the back of the case on the line 3 3, Figs. 1 and 2. Fig. 4 is a sectional view of the soap-shaving cylinder detached. Fig. 5 is a sectional view of a modification, and Fig. 6 is a plan View of the upper end of the feedscrew.

The main frame of the device comprises a fixed part in the form of a backplate C and a cylindrical inclosing casing B, hinged at K to the back plate C, which latter is mounted upon astandard N, suitable for attachment to the top plate of a fixed Washbasin. Through an opening in the front of the inclosing casing projects the closed front face of the soapshaving cylinder A, which is shown separately in Fig. 4. This shaving-cylinder A is separable from the back plate and is provided with an outwardly-projecting rim or flange A at its inner open end. lThe outer surface of this iiange is fitted into a bearing in the outer casing B, and the ange is held in position when the casing is closed and latched or locked, as at l, by means of an inwardlyprojecting liange or shoulder-b in the outer casing and an annular projection o, on the inside surface of the back plate C. A bearing is thus formed in which the shaving-cylinder can be rotated within the outer cylinder by means of a projecting handle h on the front of the shaving-cylinder.

The shaving-cylinder has a series of knives M at its periphery or side walls, and these, knives may conveniently be formed out of the sheet metal of the cylinder itself, as by slotting the cylinder at m and bending the following edges of the slots inward, as shown in Fig.2 Between the shaving-cylinder and the outer casing B an annular space is formed about the knives, intowhichthe soap shavings pass as they are cut away and fall to the bottom of the space, where a discharge-outlet c in the casing is provided.

To hold the cake of soap in place, I form on the inner face of the back plate sharpedged vertical ribs or guides D D, and I also secure to the back plate a curved springplate P, the free end of which projects downwardly, Figs. 1 and 2, and presses against the front face of the cake of soap, which is thereby pressed into holding contact with the ribs D D, as indicated by dotted lines in Figs. 1 and 2.

To keep the soap up to the inner face of the cylinder or to provide for the feeding forward of the soap cake to the cutting-knives as the soap is cutaway, I prefer to use a feedn screw S, mounted in bearings e e in the back plate and having its thread engaged with semicircular threads at the diagonal upper and lower parts of the bore of a feed-nut F, which is suitablyguided in the back plate and bears upon the soap cake, as shown in Fig. 1. To turn the feed-screw, I provide at its upper end studs s s, with which engages a spiral groove or thread a on the inner face of the 'rim A of the revolving cylinder A. The diagonally opposite parts of the hole through the feed-nut F are cut away, as shown in Fig. 1, to permit the nut to be run back by hand toward thestarting end of the feedscrew S, a Well-known expedient. Instead of using a feed-nut, however, I may form, upon the screw itself, as at S', Fig. 5, adeep and sharp-edged thread, which may engage the soap cake itself to feed it forward.

The feed-screw is located atone side of the center of the casing, as shown in Fig. 2, and so arranged that the spiral or thread on lthe shaving-cylinder will engage with the studs on one side of the feed-screw and clear those on the opposite side. The arrangement and proportioning of the spiral, the studs, and the hinge K are such that in opening the casing to replace the soap the spiral, which falls away from the casing and knives, will draw the stud with which it is engaged through a fraction of a revolution and then freely disengage, so that the casing and shaving-cylinder may be withdrawn from the back plate together. In closing the casing a similar action in the reverse direction takes place.

I claim as my invention- 1. A soap-ilaker, comprising a casing having a discharge-outlet, a rotatable cylinder having knives located in its periphery within the cylinder, stationarymeans for holding the soap within the cylindei` and means for feed` ing the soap to the knives, substantially as described.

2. A soap-aker, comprising a plate with sharp projecting guides, a spring adapted to force the soap against the guides and a feeding device adapted to feed the soap in the direction of the guides, substantially as described.

3. A soap-shaver, comprising a plate, a casing, a rotatable knife-cylinder within the casing, a device for holding and feeding the soap to the knives Within the cylinder and means for operating said feeding device by the rothe casing and gearing between the rotatable knife-cylinderand feed device, substantially as desebed.

In testimony whereof I have signed my name to this specicationin the presence of two subscribing witnesses.
