P. DIETRICH RAZOR BLADE HOLDER May 3l, 1938.

Filed April 1'7, 1937 Patented Mey 31, 193s UNITED "s'iii'rits PATENT or FICE RAZOR-,BLADE HOLDER reni Dietrich, LoeAngeiee, oeuf. Appiioation April 17, 1937, serial No. 137,515

' s claims. (ci. lao-ssei This invention has to do in a general way with cutting or scraping devices, and is more par ticularly related to that class of such devices which are designed to utilize razor blades as the 5 cutting or scraping elements.

It. is the primary objectof this invention to provide an improved razor blade holder which is of simple form and construction and may be ecol nomically manufactured, such` holder being so lo designed that it can be readily dismantled and reassembled for the replacement of the cutting element or blade. In this connection, my invention contemplates a device in which the blade is supported between two separate. jaw plates -having opposed faces formed so as to ex the blade when they are pressed together. In this way,'the

ex resisting tension of the blade tends lto force the two plates apart. Associated with the supporting jaws or plates I provide a frame whichl has its side ways adapted to receive the end por- Y tions of the plates, such ways being dimensioned lso as.to press the two plates together, thereby flexing the blade so. that the tension of the blade is utilized to hold the supporting jaws in fricgr, tional engagement with the frame. i

It is a further object of this invention to provide a blade holdingmember of the class described which is constructed so that the bladei supporting jaws can be completely removed from :i the containing frame and reversed and reinserted in the frame to provide a holder for the scraping or cutting edge which protects the same. In

this way, I have provided a device which' can be easily carried in the pocket and in which the blade can be made available merelyby removing the jaws'and reversing their position in the frame. K

The details in the construction of a `preferred embodiment of my invention, together with other4 i objects attending its production, will be best understood from the following description of the accompanying drawing, which are chosen' for illustrative purposes only, and in which:`

Fig. 1 is a front elevationillustrating a pre- 3 ferred form of holder and blade assembly with the cutting edge of the blade extended; Y

Fig.72 is a plan. view of the device .eas 'shown in Fig.1;

, Fig. Y'3 is a plan section taken iofFigl;

Fig. 4 is a plan section similar to Fig-3 but illus` l trating the jaws without the supporting frame so `as to show the manner in which the supporting plates or jaws' are spread apart by the blade i when positive pressure is not applied to the jaws;

so as to flex the blade when may be obtained in various ways.'

' Fig. 511s a sectional elevation takenin a plane represented by the line 6--5 of Fig.'1`; i Fig. 6 is asectional elevation similar to Fig. 5, but showingthe supportingjaws and *blade as-h sembly as having been reversed in the frame ,so 5 as to protect the cutting edge of the blade; t

Fig. 7 -ls a detached frontelevation showing the frame in section to illustrate one preferred manner of constructing the frame -so as Ato provide a ydevice which will protect the blade when-'10 the unit is Yassembled with the cutting elements reversed; and I 1 Fig. 8 is a sectional elevation of a blade andl jaw-assembly of modied construction.

' Referring nowl to the drawing for a more de- 15 tailed description of the invention as illustrated herein, reference numerals II and vI2 indicate plates or jaws which have opposed faces I3 and III adapted to engagea razor blade I6. This t razor blade may be of any conventional type, 20 and, as is usual in the construction of such razor blades, it is provided with openings II--Il formedI along a medial line. In the present embodiment of this invention, I take advantage ofthese openings to provide means for holding or 25 supporting the bladey against transverse movement relative to its supporting jaws. I accom-` plish this by providing one of the plate members (I I) with projections I8 and I8 which are alined'` with openings LI9 and I9 in the other plate 30 member (I2), such projections and openings being situated -so as to fall into alinement with the openings in the razor blade itself. In this way, whenthe two jaws and the razor blade are assembled, the projections extend through the 35 openings inthe razor blade and support such i blade against transverse movement.- `These openings .and the size of the plates areso proportioned that one edgeof ,the blade extends from the plate when the three members areassembled 4,04

and the other edge of the blade'is vcontained jwithin the space lbetween the plates.

-, As I have Vpreviously pointed out, ,the opposed yfaces ofthe jaws or plates II and I2 are shaped these ,twotplates are 45 pressed.- together 'withthe blade therebetween.

This flexing action-is utilized to spread the two plates apart. by' the .tension of the blade andi In the preferred en ibo'i'limentofI my invention 50 as illustrated herein, the flexing action of the blade as just describedis obtained by providing. one of the jaw plates (I2 -for example) with an inwardly extending bulge or projection indicated by reference numeral 2|, andjby providing the 55 `With this arrangement, it will be seen from Fig. 4 that when the two plates are assembled with a other jaw pmeu l) 'witha recess 'zz'tnat is op# posite. the, bulge or projection 2l on the plate I2.

blade therebetween that the bulge' or projection 2l on the plate I2 acts upon the blade I8 to hold ythre two plates in a slightly spaced relation.

In the present embodiment of my invention' the ends of the'plates are shown as being grooved as indicated generallyby reference numeral 24, so that when the plates or jaws" are'assembled these grooved end portions cooperateto form dove-tailed projections generally indicated by ref erence numerals 26 and 26'. These dove-tailed projections areadapted for reception in correspondingly shaped ways 21 and 21 formed in the 4 side members 28 and 28' of an open-sided frame generally indicated by reference numeral 29.

` into engagement with the ways, settingup sufll,

scraping tool the jaw lie-@provided with being flexed along As is perhaps open-sided frame section having a closed best illustrated in Fig. '1, this side member 30 preferably formed with a depending recess Il.

f' The ways21 and 21 are-dimensioned in cross` section `so that their width is substantially equal to the width of the end portions of the plates plus thewidth or thickness of the blade, and in this `way when the blade and plate assembly is forced into the ways it will be seen that the two plates are pressed inwardly toward each other, thereby flexing .the blade so blade to flexure exerts outward pressure on the plates and presses the ends of the plates rmly cient frictional `resistance tov positively hold. the jaws tightly assembled within the frame.A

When theunit is to be used` as a cutting or and blade assembly is inserted within'the frame in the manner illustrated .in Figs. l-and 5. When the unit `is not in use it is preferableto yremove, the jaw and plate assemor the corresponding opposed surface in the frame. This arrangement-is perhapsbest illustrated in Figs.`6 and 7.

To facilitate handling and working with the device, one', or both, of the plate'members may a depression 3.6 on its .outer surface. f

As previously stated, the' flexing of the blade by the opposed faces on be 'accomplished in various ways and in Fig. 8 Ijhave illustrated amodiied form of my invention-in which this ilexure is obtained by cooperatively curving the opposed faces lof the plate longitudinal axis. In other in this form of my invention, longitudinalaxis instead of two axes Aas was the 4case when a small hump or projection was formed `members-along a words-the blade, is flexed along one on one face and a correspondingly formed de-l pression was provided on the otherlface.

w It will be apparent from the foregoing description ,that the device contemplated by this invention is oi' simple form and construction, it may .'be easily and cheaply manufactured, and can be 29fismade .of U-shaped cross that the resistance of the the plate members may J readily4 assembled and dismantled. It will also be observed that it affords -the added feature of protecting the blade and guarding the cutting edge when the unit is not in use.

It is to be understood that while I have herein described and illustrated one preferred embodiment of the invention. the invention is not limited to the precise construction described above and includes within its scope whatever changes fairly comewithin the spirit .of the appended claims.
