FRANK C. CURTIS, OF TROY, NEW YORK.
Application filed January 8, 1916, Serial No. 70,947. Renewed July 19, 19%.
To all whom it may concern:
Be it known that I, FRANK C. Courts, a citizen of the United States, residing at Troy, county of Rensselaer, and State of It New York, have invented certain new and useful Improvements in Lathering Utensils, of which the following is a specification, referen e being made to the accompanying drawin forming a part thereof.
The invention constitutes an improvement on the invention shown and described in United States Letters Patent No. 926,303, dated June 29, 1909, granted to Charles E. Thompson, for lathering utensils.
Certain objects of the invention are to re dude the cost of manufacture; to facilitate the assembling of the parts into the finished utensil; and to avoid the use of metal in the utensil.
Other objects will appear in connection with the following description.
The single figure of the drawing shows a central vertical longitudinal sectiou of a lathering utensil embodying. my invention 25 in the preferred form.
The handle,-, 1,'projects laterally from a brushhead, 2, and is preferably integral therewith.
The brush-head is provided with a ver- B tical bore, the upper portion, 3, of which may be substantially cylindrical, and the lower portion. 4, of which is preferably downwardly tapered to receive and fit a.
similarly tapered butt, 5, of a knot of brisas tles, (3, the flexible portion of the knot projecting downwardly from the bore.
The cylindrical portion of the bore is occupied by a plug, 7, preferably resting upon the top of the butt, 5, and projecting from 40 the bore.
The projecting end of the plug, 7, has an overhanging flange, 8 partly forming a groove, 18, to receive an annular edge-flange, 19, of a finger-pad, 9, bordering an opening in the bottom of the pad, the pad being chambered to receive the flanged end of the lug, whereby the pad is secured upon the )rush-head. I
The pad, 9, is made of soft vulcanized rub- M her having numerous integral fingers, 10, projecting therefrom, forming a massa e device which is particularly useful forru bing in the lather preparatory to shaving. The knot of bristles may be formed in any known manner; but is preferably formed by-embedding the butt-ends of the bristles in rubber vulcanizedinto a hard unyielding body forming the butt, 5, of the knot, which can be made to fit closely the tapered portion, 4, of the bore, thus, if desired, dispensing with the use of a metal ferrule for the butt-end of the knot.
When the upper portion of the bore is made cylindrical, as shown, I prefer to provide a distinctshoulder, 20, at the junction of the cylindrical and tapered portions, to limit the penetration of the plug into the bore and thereby secure accuracy and uniformity in the projection of the flanged end of the plug from the upper end of the bore, and the projection of the body of bristles, 6, from the lower end of the bore.
The finger-pad is preferably formed with a free space, 11, between the ad' and the top of the plug, and the top of the plug ispreferably recessed, as at, 12, to contribute to the extent and efiieiency of said space to.
permit the finger-pad to yield inwardly.
My invention makes it possible to separately turn fromwood, if desired, the handle and head, 2, as anintegral piece, and the the shoulder, 10.
If desired the butt of the knot may be cemented in the tapered portion of the bore and the plug cemented in the c lindrical portion of the bore and also to t e top 0 the butt, 5. I
Other means may, however, be employed to secure the plug within the bore, as a nail. 13, or the like, passing through the wall of the head, 2, into the plug.
From a long series of tests, howeven'fI believe the plug can be satisfactorily se cured in the bore. by suitable cement with,- out the use of the fastening device, 13; and I have found ordinary shellac suitable-for this purpose. 11w
If wooden pieces are. employed, I'prefer to have them covered with waterproof enamel,
or finish; and when so made and the plug is pro fitted to and cemented 1n the rl bore, t e diavice will be substantially waterand watertight.
vIoa'med with a recess,
pro ecting from one the plug prevents escape of the bristles from the bore and secures the pad to the head. r
2. A lathering utensil comprising ahead provided with a bore, a handle projecting aterally from the head, a knot of bristles end of the bore, said head and knot having means for preventin relative movement between" the head an said plugfhaving .a flange and tapered at the other,
bristles in dile direction including a butt end'of the bristles seated within" the bore, a fingerad,- and a. plug securedin. the other end 0 the bore and projecting therefromi lgroove adjacent the head, the finger-pad aving a portion engaging'the peripheral prevents the escape groov'e whereby the plu e bore and secures of the bristlesfromt the pad to the'head.
3. A lathering utensil Eomprising a head having a bore cylindrical at one end and a handle projecting laterally from the head, a knot of bristles projectlng from the tapered end of the'bore and having a similarly tapered butt seated. therewithin, said butt cooperating with said bore to and bristles in one direction, a
a periphera Y greventrelative movement between bore and havin spaced from the ing the flange on prevents escape of the bristles from the bore and secures the pad to the head.
4. A lathering utensil comprising a head having a bore cylindrical at one end and tapered at the other and having a shoulder at the inner end of the cylihdrical portion, a knot of bristles projecting from'thetapered end of the bore and having a tapered butt fitting therewithin, the butt cooperating with said here to prevent relative movement of said bristles and head in one direction, a finger-pad, a plug having a cylindrical portion fitting and secured Within the cylindrical portion of the bore and abutting against said shoulderand the buttof the knot of bristles, said plug having a flanged end exterior to the bore, the finger-pad being engaged by said flanged end, whereby the plug prevents escape of the bristles from the bore and secures the pad to the.
5. A lathering utensil comprising a head provided with a bore, laterally from the head, a knot of bristles projecting-from one end of the bore, means for preventing movement of the bristles relatlve to the head in one direction, a hollow finger-pad, a plug secured within the other end of the bore and having a flanged end projecting therefrom and extending into the finger-pad, the top of the plug being provided with a recess and there being a a handle projecting free space between the pad and'the top of the plug, whereby the plug prevents escape ofthe bristles from the bore and secures the pad to the head.
In testimon whereof, I have hereunto set my hand tli FRANK C. QURTI S.
