No. 624,778. Patented May 9, 1899.
United States Patent Office.

John Thomas Finley, of Mountian Home, Arkansas. Razor.
SPECIFICATION forming part of Letters Patent No. 624,778, dated May 9, 1899. Application filed February 9, 1899. Serial No. 705,084. (No model.)

To all whom it may concern:

Be it known that I, John Thomas Finley, a citizen of the United States, residing at Mountain Home, in the county of Baxter and State of Arkansas, have invented certain new and useful Improvements in Razors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to razors.

The object of the invention is to provide a razor for shaving purposes the blade of which may be adjusted in line with its shank for stropping or honing and so as to be used in the manner of a safety-razor, which may be moved over the face with gr eat facility and convenience.

The invention consists, essentially, in the combination of a handle or shank, a blade pivotally coupled with the shank so as to be adjustable to different positions or angles with relation to the shank, and means for holding the blade in either of its adjusted positions.

It also consists in certain details of construction of the parts and in their combination, hereinafter particularly described and claimed.

In the drawings forming a part of this specification, Figure 1 shows the blade as adjusted for ordinary use in shaving. Fig. 2 is a similar view showing the blade adjusted in position for stropping or honing. Fig. 3 is a perspective of the blade detached. Fig.4 is a perspective of the handle or shank. Fig. 5 is a perspective showing the spring latch or catch for holding the blade i in either of its adjusted positions, and Fig. 6 is a section on the line 6 6 of Fig. 2.

1 is the shank. This shank may be coupled with an ordinary razor-handle in the usual way, if desired, and it is provided with a stud 2 near its outer extremity and with a lip or flange 3, and on the side opposite the stud and flange I form by preference a shoulder 4.

5 is the blade of the razor, preferably made in the form shown in the drawings, having a hole or perforation near the middle part thereof which fits over the stud 2. The blade is also provided with lips or flanges 6, which when the blade is adjusted longitudinally of the shank engage the lips 3 of the shank and assist in holding the blade firmly against the shank. The blade is also slotted, as shown at 7, and is provided with a lateral notch 8, a longitudinal notch 9, and a second lateral notch 10.

11 is a keeper or catch provided with a longitudinal tongue 12, a flange 13, and a stud 14. This keeper is made of spring metal and is secured to the shank by means of fine screws 15 15, one end abutting against the shoulder 4. The tongue, the flange, and the stud are preferably formed integral with the spring-body of the keeper. It should also be noted that the stud 2 is preferably formed integral with the shank. The blade is held upon the stud 2 by means of a tap-nut x, screwed upon the outer end of the stud in such way that as the shank is turned or moved the nut will move with it, the end of the nut being slightly upset or headed, as is the case in scissors.

The parts of the razor being assembled and adjusted in the position shown i in Fig. 2, it will be observed that the tongue 12 passes through the slot 7 in the blade and that the flange 13 and stud 14 engage the notches 8 and 9, and by reason of this construction and organization the blade is held as firmly by the shank as though it were made integral therewith, and the razor may be honed or stropped or used in the manner of an ordinary razor.

When adjusted as a safety-razor, as shown in Fig. 1, it will be observed that the blade is held in said adjusted position by reason of the flange 13 of the keeper engaging the back of the blade and by reason of the stud 14 engaging the notch 10.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is—

1. A razor involving the combination of a shank having a stud projecting from its side near its outer extremity, and a lip or flange, a blade adjustable to different angles with relation to the shank, perforated to fit over the stud and having a lip or flange to engage with the lip on the shank, and means for holding the blade in its adjusted positions, substantially as described.

2. A razor involving the combination of a shank having a stud and lip as described, a blade adjustably mounted on the stud having a slot, and a spring stop or catch having a tongue to enter said slot for locking the blade in line with the shank, substantially as described.

3. A razor involving the combination of a shank having a lateral stud as described, a blade adjustably mounted on the stud having a slot and a notch, and a spring-plate carrying a tongue and a flange arranged alongside the shank for engaging the slot and notch in the plate and holding the same in either closed or open position, substantially as described.

4. A razor involving the combination of a shank or handle having a stud as described, a blade adjustably mounted on the stud, and a spring bar or plate having a flange for engaging the back of the blade and thereby holding the same in adjusted position, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

John Thomas Finley.
