Feb. 25, 1930. E. w. ANDERSON ADJUSTABLE SAFETY RAZOR Filed Aug. 10, 1928 lINVENTOR We( M ATTORNEY Patented Feb. 2s, 1930 PATENT OFFICE EARLWANDERSON, F ASPOKANIE, WASHINGTON ADJUSTABLE RAZOR imputation mea mgmt 1o, 192s. semi 10.298398.

The object of this invention is to provide a. novel type of safety razor.

The invention involves a blade holder and a handle which are connected in a novel ad- 5 justable manner so that the blade holder can be adjusted from a shaving position into the plane of the handle.

It is a feature of the invention to lprovide means for operatively connecting the blade 1o inthe blade holder, with the handle, so that when the blade holder and handle are adjusted to various diEerent positions, the blade will be actuated b such adjustment-into various positions in the blade holder.

Thus, in the most specic form of the invention, it is a feature to provide means whereby on one -character of relative adjustment of the blade holder and handle, the blade will occupy a shaving position, and on another character of adjustment, the blade will be retracted into the blade holder, and on still another adjustment, the blade will be projected'from the blade holder. It is a further feature to provide a blade holder, as set forth, which is readily opened or adjusted for quick removal of the blade when necessary and wherein the operative connection of the blade with the holder will be established automatically merely by the insertion of the blade into the holder.

.The device of my invention also includes a novel form vof blade which I claim as new, as an article of manufacture.

The invention has many other objects and features which will be more fully described in connection with the accompanping drawing and which will be more particularly pointed out in and by the appended claims.

In the drawing:

Like characters of reference designate similary parts throughout the different figures of the drawing.

Reference will first be made to Figs. 5 to 9 for the purpose of specicall describing the type of blade holding mem er or blade holder herein shown as embodying my invention.

Said blade holder includes what I lwill term a base or base plate 1 provided with blade receiving and holding means in the form of lateral flanges 2.. rlhe'inner faces 3, of these flanges converge, as shown in Fig. 9, so that when a clamping device, to be presently described, is forced between said flanges, the latter will snap over and hold said device. The base plate has a face 4, which I will term the blade lface, andan opposite face 5, which I will term the handle face. The shaving edgev of the base plate is provided with the usual comb or guard composition with respect to posed of teeth 6, which may be formed integral with said plate.

I have provided a form 4of blade which is shown in-Figs. 10 and 11, and which consists of a body 7, having a cutting edge 8, and provided with actuating means preferably in the form of a slot 9. This slot 9, as shown, is a linear slot that is not only parallel with the cutting ed e but is disposed remote therefrom and re atively closer to the base edge 10 than tothe cutting edge 8. 'In

accordance with my invention, this blade may be of the paper thickness so as to be cheap enough to be discarded, after a few usages, or it may be of a thicker stock that'will take repeated sharpening. i

Now, reverting to Fig. 9, it will be seen that the blade 7, ts against theface 4 and between the flanges 2, the clearance between the latter being suicient for relative movement of the blade with respect to the blade holder.

Said blade holder includes blade clamping means which, in the form shown, is embodied in a leaf 11 that is hinged at 12, to the rear ends 13, of flanges 2, so as to be swun into or out of clamping relationfto the blade As shown in Figs. 5 to 7, the leaf is closed and in Fig. 9, the same is open. The lateral edges 14, of said leaf 11, are parallel, and when forced between the converging edges 8, the leaf will snap into and be held in a blade clamping position. However, many other expedients may be devices to perform this broad function and I do not wish to be limited to the form shown except for such limitations as the claims may import. I prefer to hinge the leaf 11, to the base plate 1, as in so doing, I am always sure that the free edge 15, of said leaf, will always be in predetermined relation with the guard, when said leaf is closed. A

Reference will next be made to an operating member intermediate the handle and the blade and which member is Inounted in the blade holder.

Said member is shown in the form of a disc 16 which is peripherally shouldered at 17, in a complementally formed shouldered opening in the base plate 1, so that said disc may be rotatively adjusted. This shouldered mounting, which is clearly shown in Figs. 5l

to 7, prevents the disc from moving toward the-blade, from its normal position `and the blade side or face of the disc 16 is flush with the blade face 4, of plate 1. On its blade side or face, said disc is provided with an operating pin 18, which is adapted to slidably engage slot 9, of blade 7. Said pin 18, is

preferably of sutlicient length to extend past and through blade 7. I preferably provide leaf 11, with an arcuate guide slot 19 into which the free end of said pin 18 projects in order to assist in guiding said pin and to prevent any binding action during adjustment of said disc.

Said disc 16, is of a thickness to ldispose its remaining face substantially flush with what I will term the handle side of plate 1, as will be seen from Figs. 5 to 7 and projecting from and mounted on said handle face are two journals 20. A handle member 21 hasa reduced shank 22 that fits between said journals 20 and a suitably fixed pivot pin 23, pivotally unites said handle with said disc. It will now be seen that I have rovided a connection between the blade hol er and handle which comprises a combined swivel and pivotal connection, and lthat a part of this connection is operatively associated with the blade.

Before describing the operation, I will refer to a feature of the construction'which not only functions Vto hold the disc'in posi-A tion but which additionally functions to hold the handle in different adjustive relation to lthe blade holder.

A A spring metal sheath retainer is indicated at 24, and that edge nearest the guard 6,is suitably secured to the handle face of the base plate, 1, leaving the remaining edges v25, 26 and 27, free from engagement with said plate 1 and in suitable spaced relation thereto, as

I have provided means, which for the present illustration, and purpose, may consist of a small link 30,- suitably attached to the 'holder at 31, and to the handle t 32, and which attachments may be disconnected when the holder is to be adjusted into any of the positions shown in Figs. 1 to 3.

Thus it will be seen that the disc and handle may readily be detached from the blade holder by springing the sheath 24 sufficiently to release the disc 16 from the base plate 1. With such disconnection of the parts, it will be clear that with the blade holder opened, as shown in Fig. 9, the whole structure is rendered accessible for cleaning or renewal purposes. In order to facilitate the holding' of the handle and blade holder in the various relative positions shown, I consider it a feature of my invention to bend the corner portions 33 and 34, of the sheath 24, downwardly, j

as shown, so thatthe handle will be frictioning than any other safety razorofthis type,

either for gross shipment or for individual packing convenience. Furthermore, itis 'a feature of this invention to provide a safety razor with means for projecting a blade for cleaning or stropping purposes and withdrawing or retracting the blade when the razor is not in use, thereby preventing exposure of the cutting edge. In the following description of the operation, I will explain how and by what means the strcture affords the above various advantages. l

In the shaving position shown in Fig. 4, the edges 28 of the slot coact with the sides of the handle shank 22, to hold the blade holder tion, the disc 16 will hold the blade 7, in

such relation to the guard 6, as to be in effective shaving relation thereto, 'such relation being shown in Fig. 5. A f

When it is desired to adjust the blade holder into the plane of the handle, the parts are adjusted. into the position shown in Fi s. 1 and 5, by disconnecting link 30 and shi ing the blade holder as shown. This adjustment might, in itself, be a valuable and advantageous one apart from the adjustments to be presently described. However, the edge 8, of the blade 7, in this initial adjustment, is still in the same shaving position as in Fig. 4, and would of course not be protected. However, it will now be clear that the sl in sheath 24 permits the holder to be'adjusted from the shaving position shown in Fig. 4, to the initial collapsed position shown in Fig. 1. v v

Assuming' that the user had finished shaving, in the course of this description, and wanted either to clean or strop the blade prior to putting it away, then, he would shift the blade holder into the position shown in Figs. 3 and 7, in which position the blade is projected sufficiently to be cleaned of all lather or soap and is equally adapted to be stropped.

After the blade has been cleaned and stropped, then, the user can adjust the holder into the position shown in Figs. 2 and 6, in which position the blade is retracted into the holder soas to be aforded the protection of the latter as a case therefor, the cutting edge being clearly out of a position for contact with anything.

Thus it will be seen that theuser need never remove the blade either for cleaning or stropping purposes, and it will now be clear how the relative movement of the holder and handle serves, through the disc 16, andthe pin and slot connection, to correspondingly shift the blade into the various positions shown.

It may be desirable to briefly recapitulate the operation in detail.

In shifting the holder and handle from the Fig. 1, to the Fig. 2, position, the disc 16 is positively actuated and by reason of the fact that the blade 7 is guided by the flanges 2, I insure a positive and unvariable parallel relation between the guard 6 and the cutting edge 8, irrespective of the extent of movementof the blade 7. Further, by reason of the constant engagement of the pin 18 with slot 9, the blade 7 will be positively held in its adjusted positions. y

When the holder and handle are relatively adjusted from the Fig. 2 to the Fig. 3, position, the disc 16 is actuated in the reverse dif rection to that illustrated in Fig. 2.

It is also informative to state that while the leaf 11 firmly engages the blade 7 and holdsthe latter sufiiciently ti htly against the base plate 1 to prevent wo bling move/ ment of the blade,-still, this engagement isV not sufficient to burdensomely resist adjust-- ment of the blade to the various positions shown and is only suiiicient to act as an advantageous drag to prevent a too free movement of the holder and handle. Thus, in

order to make the various adjustments shown in Figs. 2 and 3, it is not necessary to first release the leaf 11.

It is believed that the invention will be fully understood from the foregoing description, and while I have hereinv shown and described one specific form of my invention, Ido not wish to be limited thereto except for such limitations as the claims may import.

I claim:
