'SAFETY RAZOR.

Application filed November 14, i927. serial No. 233,006.

This invention. relates to shaving devices and more particularly to the type known as safety-razors.v

The objects of my invention are to provide improved mechanism whereby the safety guards of a safety razor may be swung froni' from the following description read in conjunction with t-he accompanying drawmgs in whicht- Figure 1 is a plan view of a razor incorporating my invention showing the top holding` member superimposed over a blade.

igure 2 is a side view of the razor showing the relation of the adjustable guards to the blade and holding member. Figure 3 is a central. section through the razor with part'of the adjusting` mechanism broken away. Figure 4 "sa plan view of the razor blade mounting with the blade and. holding member removed.

Figure 5 shows .the construction of the holding member. Figure 6 is a front view of therazor illustrating thev construction o-f the' adjusting mechanism in the handle.

Figure 7 illustrates a receptacle wherein therazor may be kept when not in use. The .pair of rolls 'accommodate an edge of the blade. and constitute asharpening means for therazor. ,f

- Figure 8*' illustrates one form of arranging the razor within a container with respect .to

the sharpeningrolls.

. Considering all the figures simultaneously, 'similar designations referring to similar parts, numeral 9 represents a razor having a handle 10 with a blade mounting 11 at one end and integral therewith. 'Hinged to mount- .ing 11 areguards 12. As indicated in Fig- .ure 4, the guards are arrangedto link with l the-mounting. Pins' connecting the guards and mounting constitute hinges whereon the guards may be swung toward the handle.

' Pins 13 interconnect the guards andmounting and extend the whole length of the device, as is best shown inFigure 4.

Each guard is swiveled by means of arms 14 to a. slide-rod 15 housed within the handle.

The handle is provided with an opening therethrough for accommodating rod 15 and is slotted at 16. Button head 17 extends throughk the slotted portion and is threaded to the rod. A movement of the button will therefore act'uate the rod which in turn controls the guards through arm 14. By tightening the button, at any desired point in the slotted portion, the guards will be fixed in position and assume a desiredl angle with respect tothe mounting member.

Integral with the mounting are provided guide pins .18. A blade 19 having perforations therein spaced correspondingly to the guide pins ofthe mounting, isslipped over the pins and held to themounting by holding member 20. Holding member 2O is arranged with orifices21 having one portion thereof adaptedto snugly engage pins 18, the remainder of each orifice being sufficiently large to pass over the heads of the pins which are of-greater diameter than the body of the pins. As is evident from Figure. 1, each pin has an enlarged head. The perfo--` rations of the blade are sufficiently large to pass over vthe heads. The thickness of the holding member is such that when the member is slid under the heads .ofthe pins, the

lblade will be tightly held on the mounting.

In use, a blade will be superimposed over the pins and the holding member securedin position under the heads to secure the blade in position.- The button 17 will then beshifted in the slot until the guards are .at a desired angle to the edges of the blade. A turn of the button 'Will'ix-the guards in position. If an unguarded edge is desired, the button will be'slpped to the bottom of the slot and the guards will assume a position adjacent the handle, as shown in Figure 8.

The drawings show the; mounting andv holding member'of curved construction. By securing the blade 'in position, the bladewill also be curved, as shown in Figures -2 and 3. It will be" understood that the mounting maybe 'made fiat so thatthe blade will present edges v'substantially perpendicular to a plane through the center line of the handle." Figure 7 illustrates a pair of'sharpening rolls situated in av container wherein the razor may be kept when not in use. WhenV the button is pulled down, the guards will assume the posltion shown in Figure 8,1 eaving the cutting edges exposed 'on both sides of the blade for a considerable distance from the edge to the center of the blade. By moving the edge between the rolls, the blade may be sharpened.

rIhe rolls are rotatably mounted on suitable supports 22 and are normally in contact with each other. When the blade descends between the rolls, one of them designated 'by numeral 23 in Figure 8 will recede from its position due to support 22 being slidably arranged within a mounting slot 24. Leaf spring 25 is arranged to return the roll to its normal position in contact with its associated roll when the blade is withdrawn from between the rolls.

Various modifications may be made in the design of the razor and holding device without departure from the mechanical feature called for by the claims.

What I claim is 1. In a safety razor, a handle bored and slottedfor part of its length; a blade mount! ing fixed to take through the holes in a double ed ed safety razor blade, the holder having a xed central part extending longitudinally of the blade and materially narrower than the blade, a holding member ma?.

l terially narrower than the blade adapted to clamp a razor blade to the blavde mounting; guards hinged to theI sides of the blade mounting; a rod slidable in the bore of the handle; means for locking the slide rod in adjusted position, and links connecting the guards with the slide rod whereby, by actuation of the slide rod, the guards maybe swung from alignment with the blade holder Vinto a position adjacent the handle or may be swung in reverse direction.

` 2. In a safety razor, a handle bored and slotted for part of 1ts length; a curved blade mounting fixed to take through the holes in a double edged safety razor blade, the holder having' a fixed central part extending longitudinally ofthe blade and materially narl-rower than the blade, a curved holding member materially narrower than the blade adapted to clamp a razor blade to the blade 3. In a sa ety razor, a handle bored and slotted` for part of its length; a blade mountving fixed to one end of the handle, having a fixed central part materially narrower than the blade; headed pins extending from the fixed part of the bladeholder and adapted to` take through the holes in a' double ed ed safety razor blade; a bladeCholder, materilly narrower than the blade, having perforations with a diameter suflicient to pass over the heads and narrower extensions adapted to slide over the pins and clamp the holder and blade to the blade mounting; a rod slidable in the bore of the handle; means for locking the slide rod in adjusted positions, and links ,connecting the guards with the slide rod whereby, by actuation of theslide rod, ,the

guard may be swung from alignment with the blade holder into a positidn adjacent the handle or may be swung in reverse direction.

In testimony whereof I have signed my name to this specificatlo'n. l J EREMIAI-I T. MINAHAN.
