Fig. 3 is an elevational view of the holder These plates are formed from thin sheets of with the blade engaging plates swung apart so metal and the length thereof corresponds with as to receive or permit the removal of a blade. the length of the inverted U-shaped member 12. Fig. 4 is an enlarged cross section taken on Formed integral with and projecting rear- 50 e e Of -Y wardly from the upper portions of the blade Fig. 5 is an enlarged cross section taken on the clamping plates 20, are ears 21 which, when theline 5-5 of Fig. 1. s plates are properly folded into the holder, occu- Fig. Gis an enlarged cross section takenion py the notches or cut away portions 13in the the line 66 0 1. I body of the holder and these cars 21 are pro- 55 vided with short longitudinally disposed slots or openings 22 that provide convenient finger holds when the plates are swung out of the holder.

When the plates are folded into the body of the holder, the openings 22 coincide with each other and with the notches or cut-away portions 13 and said openings enable the thumb and index finger to readily engage the rear ends of the blade holding plates when the same are to be swung outwardly from their. position between the walls of member 12 and the friction plates 15 thereon.

Projecting from one of the plates 20 is a pair of studs 23 that are adapted to pass through the apertures in certain styles of safety razor blades when the latter are positioned between the plates of the holder and formed in the lower edge of the other one of the plates 20 are notches 24 for the accommodation of the ends of the studs 23 that project through the engaged razor blade.

Slots 24 are concentric with the axis formed by rivet 17. 1

The form of holder illustrated in Fig. 3 is especially designed for receiving and holding Gillette types of safety razor blades while the construction illustrated in Fig. 7 has the studs and slots spaced at greater distance apart so as to conveniently receive and retain other types of safety razor blades such as the Valet.

In Fig. 8, the plates 20 are illustrated as provided with longitudinally disposed slots 25 for the accommodation of reenforcing members that are formed on certain makes of safety razor blades suchas Gem, Star, Everready and the like.

In the use of my improved holder, the plates 20 are swung into the positions as illustrated in Fig. 3, so as to expose practically theentire inner face of the plate that is provided with the studs 23 and the blade to be sharpened is positioned on the plate that is provided with the studs with the latter projecting through the apertures in the blade.

The ear 21 on the plate that is provided with the slots 24 is now swung around into position upon the plate on which the razor blade rests by pressure of the thumb or finger on the ear 21 of the slotted plate and when so positioned the razor blade is firmly seated betweenthe two plates 20.

Both plates are now swung inwardly toward the holder so that their rear or upper edges pass between the friction. plates 15 and due to the resiliency in the metal of which the holder is formed and the spacing of the plates 15 relative to the thickness of the combined plates 20 and interposed razor blade, the blade holding plates 20 will be firmly gripped between the parallel plates 15 and the stropping operations'may now be readily accomplished.

During blade sharpening operations, the covered handle 10 is held in the hand and during the stropping strokes of the holder, the lower exposed edges of the ears 21 are engaged in succession by the thumb and finger, thereby effectually preventing the blade holding plate from shifting or moving out of their position between the friction plates 15 during the stropping operation.

To open the holder for the purpose of removing or reversing the position. of the blade, the thumb and finger engage in the apertures 22 in the ears 21 and by exerting outward pull on said ears, the plates 20 will be swung outward away from the inverted U-shaped member 12 and after such operation the slotted plate 20 is swung away from the plate that is provided with the studs, thereby exposing the blade and permitting the ready removal or reversal thereof.

When a blade is positioned between the plates 20 and the latter are swung into the slotted forward portion of the handle, the straight upper edges of the plates engage against the upper portion of the handle opposite from the parallel friction plates 15 and thus a firm bearing is provided for said plates 20 throughout their lengths and the engagement of the perforated ears 21 in the slotted neck portion 14, together with the pressure of the friction plates 15 and the pivoting of the plates 20, to the forward end of the handle, functions to very firmly grip and hold the blade receiving plates within the holder and effectually preventing the same from tending to swing outwardly from the holder as a result of the friction developed during stropping operations between the blade and strop.

A decided advantage 'inthe manipulation of the holder and particularly the blade receiving plates when the latter are opened or closed, residesin the construction whereby said plates are pivotally connected'to the forward end of the'body of the holder and. the formation of the perforated ears 21 on the rear ends of said plates for, such construction plus the length of the blade engaging plates, produces or developes ample leverage to enable the plates to be readily swung outwardly from their position between the friction plates 15 on the portions 12 .of the holder. 1 Further, this particular construction enables the plates to be opened and closed with comparative safety against accidental injury to the hand and fingers as a result of contact with the exposed edges of the razor blade that is positioned between the clamping plates.

In some instances it may be found desirable and advantageous to slot the body of the holder throughout its entire length and to form the blade gripping plates 20 of a length equal to or slightly gerater than the length of the holder so that the rear ends of said plates are engaged at the rear end of the handle of the holder when said plates are swung out of the holder'and such construction provides greater leverage to facilitate the opening or swinging outward of said plates and likewise provides a strong and substantial construction when the blade engaging plates are folded into the holder and conseparts of my improved safety razor blade stropping holder may be made and substituted for those herein shown and. described without de-' parting from the spirit of my invention, the scope of which is set forth in the appended claims.

I claim as my invention:

1. A stropping holder for safety razor blades, comprising a handle having a slotted forward portion, a pairof separately formed independently movable blade engaging plates pivotally connected to the forward end of said handle and adapted to swing into the slot therein, means associated with the pivotal means between said plates and handle for holding one side of said handle against movement toward the other side,

the width of which plates is such that their 'rear portions of the plates when the same are positioned within the slot in said handle,

2. A stropping holder for safety razor blades, comprising a handle having a slotted forward portion, a pair of separately formed independently movable blades engaging plates pivotally connected to the forward end of, said handle and adapted to swing into the slot therein, means associated with the pivotal connection between said plates and handles for holding one side of said handle against movement toward the other side, one of the blade engaging plates being provided with apertures, studs projecting from the other plate and adapted to-extend into the apertures in the other plate when the two plates are folded together, the width of which plates is such that their upper edges bear against thewall and the handle when said plates are moved into the slot in said handle, the walls of said handle at the rear of said slotted forward portion being provided-with a notch and flanges projecting inwardly from the walls of the handle immediately above said notch for frictional engagernent with the rear portions of the plates when the same are positioned in the slot in said handle.
