Specification of Letters Patent.
Application filed September 2, 1.913Y
To oli w71 om it m (17,/ fonce/rn.'
le it known that I. DAVID SCi-murali, a subject ol the lzar ot' Russia, residing in the borough ot Bronx, in the city ot' New York, titan of Non' York. hare made certain new and ust'fl'ul Improvements in Sa city-Razors. ol' which the Yl,`f. l..lo\\ing description a specilieation. reference. being had to the aoeorumuying drawings. 1
'llu invention relates to that class of lvl/:o s in wh' Vli the cutting blade is a separate part and is held or clamped in position by a ,handle which presses two plates together on the blade.
The ohjert of the invention is to avoid the bonding of the blade and at the same time steady the ri'itting blade in its position in the holder` p My iinlum'enients also reduce the number nl parts required to hold the razor blade in piave The improvements are also designed to ru'otect the userfrom cutting with the corners of the blade by extending the guard plate past the ends of the blade.
la the drawings Figure l. is a front elevation oi" my derive; Fig, is an end eleva tiouf li'ig. is a central cross-lsection of Fig. l. Fig. fl a cross section through Fig. il :in the line .r Y fr and Fig. 5. is a detached View ol they damping plate.
The lullder of the cutting blade made in two parts. (lne ot which eomprises the handle A integral with a guard plate B.
' Along nach side of the guard plate B are lingers u, o set at an angle as shown 1n Fig. 2.
C the flaulping plate having a central pin i whieh is threaded at its free end. The plate (l a nd pin .71 are integral and form one piece of the apparatus. Between the two plates ll and is clamped the cutting blade l). `which proiects over the lingers a. The handle A `nollow and reeeives a tube E introdueell' from the outer end. The tube E terminates in a threaded end adapted to serew into the end ot" the handle A and provided with a roughened nut r?. The blade D is pierced at its center with a hole through which the pin l) passes. About midway in the length of the handle A is located a screw Patented Dec. 1, 1914.
serial No. 787,619,
as shown at h. The pin t of the clamping plate (his made integral with it or rigidly secured to it.
The guard plate B is of the proper length to lie within the lips or confining rims l1., h, at the ends of the clamping plate C, and the guard plate B, has its ends shaped to fit ex! actly within the space inclose'd by the rims. The razor blade should be of the exact length ot' the guard plate and shaped at both ends lo Ht snugly Within the rims l1., The holding device it will be seen thus consists of two parts only g or at least only two parts which are separated when in changing the razor blade, The. razor blade forming a removable part held between the two plates of the holder. The handle and the guard plate do not vary their position as regards eael` other, but the clamping plate C is adjusted ond l' rom the guard plate by inea ns of its central stem b, which passes through the hole in the blade.. The ends of the cutting blade are shaped to fit snugly within' the inolosing rims h, il.. of the clamping plate C so that it will not have any lateral or circular move ment when the clamping platos are pressed upon it.
The end ngers of the guard plate B are notched and'extended pas! the ends ot the raised rims l, k. of the clamping plate C, at the points z'. 7', Fig. l. so that a portion of the guard plate lies between the o-gee shaped raised rims and a portion across the end* thereof. This causes the two plates to snugly when -superixnposed and projects the fingers past the ends of an intervening cuttingr blade.
Hai ing desuribed my improvements what I elaini as mv invention and desire to secure by Letters Patent is:
In a safety razor blade holder, an usr clamping plate having raised inclosing end and held in the handle h3' n. mbe E and screw lips and :i central stem rigidly attached cap f5', substantially ihereto said stem terminating in a threaded end, in combination with a handle and guard 5 plate rigidly attached to the handle, a screw nut G, having u circular groove g positioned down and deacrifed.
