Specification of Letters Patent.

Patented June 112, 11917.

Application filed March 11, 1915. Serial No. 13,786.

To all whom it may concern Be it known that we, BERNARD TEWELOW and SoLoMoN TnwELow, citizens of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Cutters for Removing Hair from Cavities, of which the following is a specification.

This invention relates to a safety cutter for the removal of short hairs that grow in the human nostrils and ears.

One object of the invention is to provide a safety cutter that is mounted on a shank or handle to be revolved and which cutter will remove hairs in the nostril or in an ear by inserting the cutter in position close to the hair and then revolving the shank and cutter.

The invention is illustrated in the accompanying drawing in which,-

Figure 1, shows the manner of using the cutter in removing a hair from the nostril.-

Fig. 2, is a side view of the cutter.

Fig. 3, is a longitudinal section of the cutter. i

Figs. 4 and 5, are views of the cutterblade.

Fig. 6, is a face view of the back plate of the holder for the cutter-blade.

Fig. 7, is the safety guardfor the cutterblade. Y

Fig- 8, is a cross-section on the line 88 of Fig. 2, showing the position of the back plate, cutter-blade and guard.

Fig. 9, is a cross-section on the line 9-9, of the back-plate. V

Fig. 10, is a cross-section on the line 1010 of Fig. 7, showing the screw shankof the guard.

Referring to the drawing the cutter device as a whole comprises a shank or handle 11, which preferably has polygonal sides and at one end has a socket 12, that opens axially and which is internally screw-threaded. The three parts of the cutter proper consist, of a cutter blade 13, a back plate holder 14, and a safety guard 15,the said cutter-blade being between the back plate and guard,and each of said three parts having a shank and all the shanks in alinement, a screw thread 16, around the exterior of the two outer'shanks enters the screwthreaded socket-.12, in the end of the handle, and thereby said socket binds together the three parts of the cutter proper.

' The cutter-blade 13, shown separately in right angle on its concave face and covers the end 24, of the cutter-blade when the parts are assembled. This back plate 14:, has a reduced end or shank 25, that is concave on its front and rounded on its exterior,

.and the exterior has the screw-thread 16,

already mentioned.

The guard plate 15, shown separately in Figs. 7 and 10, has a partly rounded surface that takes against the thin cutter-blade 13, and is provided with two pin-holes 26, with which the pins 23,.of the back plate 14, engage"; this guard plate has a shank-end 27, shown in Fig. 7, and in cross-section in Fig.

' 10; the exterior rounded part of this shank is screw-threaded as at 16.

When the three parts of the cutter proper are assembled the cutter end in cross-section is more than half cylindric, and the thin cutter-blade 13, is between the back plate 14, and theguard plate 15, as seen in Fig. 8, and the pins 23, that are fixed on the back plate extend through the holes 19, in the blade, and engage with the holes 26, in the guard as seen in Fig. 2. All, three of the shanks, 17, 25 and 27, are in alinement together and these three enter the socket 12, in the handle and the screw-thread 16, on the two, outer shanks engage thescrewthread of the socket and thereby the several parts are kept in their proper relative position.

The manner of using this hair-cutting tool to remove a hair from the nostril is shown in Fig. 1. By placing the end of the cutter into the nostril and by the action of the human thumb and fingers revolving the handle 11 back and forward, a hair may be readily out instead of being extracted root and all,as the latter is often productive of sores. In like manner hairs may be removed from the ear.

Having thus described our invention what we claim is, y

In a safety cutter for removing hair from til the cavity of the human nostrils and ears the combination with a handle having a threaded socket in one end, of a back plate holder having a concave inner side and a convex outer side and provided at one end with a shank which latter has a concave inner side and a threaded convex outer side; a guard also having a concave inner side and a convex outer side and provided with a shank which projects from one end thereof which latter shank has a convex innerside and a threaded convex outer side and a normally flat spring blade between the back Y plate holder and the guard, and said blade also having a flexible shank at one end which projects between the inner concave side of the plate holder and the inner convex side of the guardand said three shanks projecting into and the threads on the plate holder shank and the guard shank engaging the threads in the handle-socket and clamping the shank of the blade between them.

In testimony whereof we aflix our signa tures in presence of-two witnesses.
