Oct. 8, 1963 R. M. MILBRANDT EYEBROW SHAVER-TRIMMER Filed Dec. 12. 1960 RDELL M. MILBRANDT ATTORNEY United States Patent ()1 (ltlll West (N) St, Epringtield, Greg.) Filed Dec. 12, I960, Ser. No. 7 5,265 2 Claims. (QB. 30-32) This invention relates to a compact shaving device for trimming the eyebrows, mustache and the like, and has particular reference to a device of such nature that may be safely carried in a ladys purse or in the pocket.

The present device is not intended as a razor for general shaving purposes, but is intended only as a t-rlrnmmg device for shaping and trimming the eyebrows or mustache.

Objects of the invention are to provide an improved razor for the purpose described, to provide a device having a small razor blade which is retractible into a slender tubular handle, to provide a dispenser for conveniently replacing the razor blades, and to provide a razor and dispenser of simple construction which may be made at low cost.

The present razor is embodied in a tubular handle or barrel of the approximate size and shape of a mechanical pen or pencil. A razor blade holder is projected from one end of the barrel for use, and is spring retracted into the barrel so that it cannot be projected accidentally while being carried in the pocket or in a purse or handbag. A special dispenser is provided for changing razor blades so that the blades do not have to be handled by the fingers. Thus constructed, the device is neat and corn pact and safe to use and carry.

Additional objects and advantages will become apparent and the invention will be better understood from the following description of the preferred embodiment illustrated in the accompanying drawing. Various changes may be made, however, in the details of construction and arrangement of parts, and all such modifications within the scope of the appended claims are included in the invention.

In the drawing: 7

FIGURE 5 is an exploded perspective view with parts broken away showing the blade dispenser;

FIGURE 6 is a sectional View of the blade dispenser taken on the line 6-6 of FIGURE 8 and showing the dispenser applied to the shaver of FIGURE 1 to change a blade therein;

FIGURE 7 is an end view of the blade dispenser; and

FIGURE 8 is a top plan view of the dispenser with parts broken away.

The numeral 1d designates a generally cylindrical barrel of approximately the dimensions of a mechanical pen or pencil, with an open rear end 11. The front end is reduced at 12 to the shape shown in FIGURE 4. Within the barrel is a transverse wall 14 having a circular opening for the stem 15 of blade holder 16.

Blade holder re is a resilient strip of metal bent to U- shape and having pairs of dimples or indentations 17 projecting inwardly of the holder to provide frictional retention for the razor blade 20. The blade is notched at 21 at its opposite edges to receive the projections 17 whereby the blade is detachably locked in the holder while, at the same time, the blade is held rigid by the clamping action of the two legs of the U holder against opposite faces of the blade. The blade is preferably tapered whereby its cutting edge is inclined relative to the stem 15 and the back edge of the blade for convenience in use. The reduced end 12 of the barrel 10 is similarly proportioned and dimensioned so that when the blade is retracted as shown in FIGURE 2 it is fully protected and housed within the tapered end of the barrel.

Blade holder 16 has a neck 2?; U-shaped in cross section and terminating in a circular collar 23 secured by a crimped or soldered connection with the reduced forward end 24 of stem '15. Neck 22 thus forms a slotted extension of stem 15. The bottom opening or slot in neck 22 is wider than the blade opening in holder 16 so that a used blade may be pushed rearwardly out of holder in along the slot in neck 22. As soon as such blade is clear of the clamp legs of holder 16 it will drop free of neck 22. This ejecting action will be described in detail in connection with FIGURE 6.

The rear end of stem 15 is screw threaded at 25 for connection with a push button plunger 3% which slides inside the barrel 1% and holds the stem in position within the barrel. A coil spring 26 surrounding the stem 15 is compressed between transverse wall 14 and the forward end of button plunger 35? to retract the blade inside the barrel as shown in FIGURE 2. When the blade is retracted, but-tonplunger 30 projects out of theopening' the detent out of opening 34 when the plunger is pressed forward into the barrel to project the razor to its FIG- URE 1 position. The blade holder is latched in its forward position by the projection of detent 33 lILiQ a for ward opening 35 in the side of the bar-rel. In order' to facilitate this locking engagement the barrel is preferablyi deformed inwardly around the region of opening '35 as indicated at 36. When detent 33 is pressed inwardly in FIGURE 1 to free itself from the rear edge of opening 35, the parts are returned to their FIGURE 2 positions under the action of spring 26. As detent 33 slides rearwardly along the inside of the barrel it reaches opening 3 and latches itself therein. Rotation of stem 15 and blade holder 16 is prevented by a projection 37 which slides in a groove 38 in the barrel.

FIGURES 5 to 8 illustrate the details of construction of blade dispenser it The front end of the blade disenser is provided with a discharge and disposal slot 41 having an enlarged upper end shaped to receive the blade and blade holder as shown in FIGURES 6 and 7. The inner end :of the upper enlarged portion of slot 41 continues forward as loading slot 42. which communicates with a blade magazine chamber -45. Guide tongues 46 enter the notches 21 of the blades tosupport a supply of blades in the magazine chamber. A spring 47 presses the blades 2% against a rear wall 4-8 of the magazine chamber which surface also forms substantially a continuation of a side wall of the loading slot 42. Tongues 46 terminate short of rear wall 48 to permit the end blade against wall it; to slide into loading slot 42.

The magazine end of the dispenser is provided with a slot having offset upper and lower ends 50 and 51 to receive a sliding blade pusher 55. The upper slot portion Stl is aligned with loading slot 42, and the back wall Patented Oct. 8, 1963 of the slot 50 comprises a continuation of the wall 48. Lower slot portion 51 is olfset beyond the end of magazine chamber 45 so that razor blades in the magazine cannot enter slot 51. Sliding blade pusher 55 has an upper end portion 56 the same thickness as a razor blade traveling in the slot 50 and an offset lower end portion 57 traveling in the slot 51. Slot 50 opens through the top of the dispenser casing 60 and slot 51 opens through the bottom of the dispenser casing whereby the slider 55 may be manipulated by top and bottom buttons or finger pieces 58 which are slidable along the top and bottom of casing 60.

The upper and lower portions 56 and 57 of slider 55 are of less width than the thickness of end wall 61 whereby the slider may be withdrawn into slot portions 50 and 51 in the wall 61 to clear the magazine chamber 45 so that the end razor blade will be pressed against wall 48 by the spring 47. One end of slots 50 and 51 is closed by casing 60 to retain the slider. The opposite end of slot 51 in the body of the dispenser and of slot 50 in casing 60 (FIGURE 8) prevent the slider from entering into loading slot 42.

The above described relationship of the parts is best shown in FIGURE 6. When blade holder 16, containing a used blade, is inserted in slot 42, the used blade in holder 16, the end blade in the magazine and upper slider portion 56 are all in line. Then, when the slider is moved into the magazine chamber, it engages the end of the blade therein which is pressed against wall 48 and slides the new blade lengthwise into holder 16 pushing out the old blade which falls out of slot 41. Slot 41 opens through the bottom of casing 60 for this purpose. When slider 55 has been moved to the limit of its travel, the new blade is properly positioned in holder 16 with the projections 17 engaged in the blade notches 21.

Holder 16 is then withdrawn from the dispenser and slider 55 is returned to its end position shown in FIG- URES 6 and 8, allowing the next blade in the magazine to be pressed against wall 48 by spring 47. Thus, the present dispenser facilitates the changing of relatively small blades which would otherwise be diflicult to manipulate into and out of the holder 16 with the fingers.

For use with the present dispenser the stem 15 of the shaver must project holder 16 from the end of barrel a distance slightly exceeding the length of the blade. This allows the used blade to be ejected lengthwise from holder 16 in FIGURE 6. Also, slot 42 which forms a socket for holder 16 should be the same length as the blade and discharge slot 41 should be slightly longer than the blade. Notches 21 provide secure but releasable retention of the blade in the spring clamp holder 16 and also support the blades in magazine chamber 45 so that the sharpened edges will not contact the bottom wall of the chamber.

Having now described my invention and in what manner the same may be used, what I claim as new and deside to protect by Letters Patent is:
