RAZOR BLADE EJEQTOR Filed April 9, 1927 Patented May 27, 1930 UNITED STATES JOHN HOLTZMAN, OF NEW YORK, N. Y.

RAZOR-BLADE EJ'EGTOR Original application filed July 31, 1924, Serial No. 729,283. Divided and this application filed April 9, 1927.

Serial No.'182,2 17.

This invention relates to a razor blade ejector, and is a division of my application for razor blade holder, filed July 31st, 1924, Serial Number 729,283.

The object of the invention is the production of an ejector to eject wafer razor blades from a holder.

Fig. 1 is a side view of a stropper to which my invention has been applied.

Fig. 2 is an end view of the same.

Fig. 3 is a vertical section taken on the line 88 of Fig. 2.

Fig. 4: is a similar view showing the positions of certain of the parts after the ejector has been operated.

Fig. 5 is a left end view of Fig. 1, some of the parts having been removed to expose the interior construction.

Fig. 6 is a horizontal section taken on the line 1111 of Fig. 1.

Fig. 7 is a side view of a wafer safety razor blade, and

Fig. 8 is an end view of the same.

The razor blade sharpener is shown to comprise a housing with the shell 55, which has connected to its ends the heads 56 and 57. The head 57 has formed therein the depression 58, the blade opening or slot 59 and the openings 60 and 61. The head 57 has formed therein the openings 62, 63 and 64;. A blade holder 65 has one end fastened to the head 57 and extends into the shell 55 up to the depression 58 of the head 56, and has extending through the walls at one end thereof the stop pin 66.

A segmental sharpening roll 68 with the strop 69 and the segmental sharpening roll 7 O with the strop 71 are located in the shell 55 with the strops oppositely positioned. The

roll 68 is supported on and fastened to the driving shaft 72, which has formed therewith the journal ends 73 and 7 4. The journal end 73 is journaled in the journal bearing 75 fastened to the head 57 in its opening 63, and

the journal end 7 4. is j ournaled in the journal bearing 76 fastened to the head 57 in its opening 60. A link 80 has one end fastened to the outer end of the journal end 74 by means of the screw and has formed at its outer end the heels 81 and 82. A second link 85 is pivoted to the link by means of the pivot 86. The link has formed at one end the heel 87 and at its other end has extending there'- from the operating handle88. A gear-9O is location in the shell 55 and is fastened to the 55 roll 68 adjacent to the head 57. j I

The sharpening roll 70 has axially located therein the sleeve 91. A shaft 92 rotatively supports the sleeve 91 and is fastened to the heads 56 and-57 by means of the screws 93. 0 A spur gear 94 is fastened to the roll 7 0 adjacent to the head 57. I

An ejector bar 98extends throughthe opening 62 in the head 57 and extendsinto the blade holder 65. An elongated guide'opening 100 is formed in the bar 98, which engages the stop pin 66. An operating finger piece or disc 101 extends from the outer end of the bar. 98. A razor blade 102 is shown with the single 70 cutting edge 103. V V To operate therazor-blade sharpener the razor blade 102 is pushed through theopening 59 into the holder 65, in which it islooSe'- ly supported to the position indicated in Fig. 75 8 and one end thereof bears against the adjacent end of the bar 98 after the latter is pulled out ofthe shell 55" until the inner end of the opening .100 bearsagainst the stop pin 66. The handle 98 is now revolved in the direction of the arrow A (Fig. 2). By this means the roll 68 turns a little more than one half of a revolution in onedire'ction and then the roll 70 begins to turn in an opposite direction. The strops 69 'and 71. alternately bear against the sides of the cutting edge of the razorblade 102, and sharpen the same. On account of the razor blade being loosely supportedin the holder 65, the said blade is alternately-moved by therolls into slightly inclined positions to alternately sharpen the opposite sides of its cutting edge. When the operating handle 88 is revolved in the direction of the arrow A, the heels 82 and 87 bear against each other and the links and are maintained With their longitudinal axial lines coincident, and the rolls are turned. If the operating handle is attempted to be revolved in a direction opposite to the arrow A, the opposite face of the heel 87 bears against the heel 81 and the energy of revolution takes the direction of the dotted line G, D, 2) and the sharpening rolls do not rotate. By

means of this construction the strops are pre-- vented from being cut by the, razor blade; After the razor blade has been sharpened it is ejected from the housing by pushing in the bar 98.

Y "The function oft'he ejecting bar 98is quite important, as the removal of the blade 102 ejector member and a finger-piece on said ejector member to manipulate the same.

In testimony whereof I aflix my signature.
