A very clever patent of a magazine razor with a tilted head in shaving position. Never made, but Kuhnl shows that he's a smart guy.

The invention relates to improvements in the type of magazine razor described in United States patents to Schick Nos. 1,730,167, 1,767,706, and 1,797,733, the salient characteristics of which are a handle containing a magazine of blades, means for ejecting the blades one by one as the plunger is operated, a post projecting from the handle, and a blade holding head so pivoted on the post that it can be swung to a position alongside the latter at which a blade receiving channel in the head is aligned with a blade emerging from the magazine. The head can also be swung to a position transversely of the post which is its shaving position. It has been found, however, that by mounting the head in the manner shown in the patents above-mentioned it is not possible to effect at the same time the most desirable shaving angle when the head is in shaving position and alignment of the blade receiving channel with the blade ejection slot of the magazine when the head is in blade receiving position. The exact shaving angle is to a certain extent a matter of choice with the individual user, but it is a fact that most users prefer a more acute angle than can be obtained by the constructions of these patents. Parenthetically, I should explain that by the term “shaving angle” I mean the angle subtended by the blade and the handle, but the meaning of the term will be presently more clearly explained by reference to the drawings.
Describing the drawings, the several figures show a preferred embodiment of the invention, the full scope of which however will be defined by the appended claims.
Describing the drawings more particularly, the handle

The parts
By reference to
In order to hold the parts of the shaving head tightly together but yet to permit it to change from one pivotal axis to another in order to accommodate it to either one of the two plane surfaces referred to and in order to permit it to ride over the projection created by the intersection of the two plane surfaces, a spring in the form of a bent washer
It is desirable that the change from one of the said axial positions of the shaving head to the other be positively effected, and therefore the shaving head is provided with a cam surface
On the other hand, as the shaving head is swung from the position shown in
In the foregoing description I have brought out the manner in which the parts function with respect one to another and so will describe merely generally the way in which the implement is used.
Assuming that there are blades in the magazine and a blade in the shaving head as shown in
While I have described a certain particular construction in which my invention is incorporated, I do not desire to be limited to this particular embodiment since many changes and modfications may easily be made without departing from the spirit and scope of the invention as set forth in the following claims.
I claim:
1. In a razor, a magazine provided with an orifice through which blades may be ejected one by one, a supporting post for a shaving head projecting from the magazine, a shaving head pivotally mounted for rotation on the post and provided with a blade-retaining slot, and the post and the head being provided with cooperating cam elements, the cam track of the cam being shaped to cause the head to take a position alongside said post at one extreme of its rotary motion with the said blade-retaining slot aligned with said orifice and to cause the pivotal axis of said head to tilt to a predetermined shaving angle when said head is rotated to a position transverse of said post.
2. In a razor, a magazine provided with an orifice through which blades may be ejected one by one, a supporting post for a shaving head projecting from the magazine, a shaving head pivotally mounted for rotation on the post and provided with a blade-retaining slot, the post being provided with a cam and the head being provided with a cam follower in cooperative relation with the cam, the cam track of said cam being shaped to cause the head to take a position alongside said post at one extreme of its rotary motion with the said retaining slot aligned with said orifice and to cause the pivotal axis of said head to tilt to a predetermined shaving angle when said head is rotated to a position transverse of said post.
3. In a razor, a blade magazine provided with an orifice through which a blade may be ejected, a post projecting from the magazine, a shaving head pivotally mounted for rotation on the post and provided with a blade-retaining slot, the post and the head being provided with cooperating cam elements, the cam track being shaped to cause the head to take a position with the blade-retaining slot in registration with the said orifice when the head is rotated to a position alongside said post and to cause the pivotal axis of the said head to tilt to a predetermined shaving angle when said head is rotated to a position transverse of said post.
4. In a razor, a blade magazine provided with an orifice through which a blade may be ejected, a post projecting from the magazine, a shaving head pivotally mounted for rotation on the post and provided with a blade retaining slot, the post being provided with a cam and the head being provided with a cam follower in cooperative relation with the cam, the cam track of said cam being shaped to cause the head to take a position with the blade-retaining slot in registration with said orifice when the head is rotated to a position alongside said post and to cause the pivotal axis of the said head to tilt to a predetermined shaving angle when said head is rotated to a position transverse of said post.
5. In a razor, a blade magazine provided with an orifice through which a blade may be ejected, a post projecting from the magazine, a shaving head mounted on the post by means of a pivotal connection, the pivotal axis of which is adapted to shift from a position at right angles to the post to a position inclined to the axis of the post, and cam means for shifting the said pivotal axis from the first named position to the second named position according as the said shaving head is swung from a position at which its blade-holding slot is in alignment with said orifice to a position transverse to the axis of the post.
6. In a razor, a supporting post for a shaving head, a shaving head pivotally mounted for rotation on the post, the pivotal mounting comprising a pin connected to the post by a hinged connection at one end of the pin, and the post and the head being provided with cooperating cam elements, the cam track of the cam being shaped to guide the head to a position alongside said post at one extreme of its rotary motion and to cause the pivotal axis of said head to tilt to a predetermined shaving angle when said head is rotated to a position transverse of said post.
7. In a razor, a supporting post for a shaving head pivotally mounted for rotation on the post, the pivotal mounting comprising a pin passing through the head and connected to the post by a hinged connection at one end of the pin, and the post and the head being provided with cooperating cam elements, the cam track of the cam being shaped to guide the head to a position alongside said post at one extreme of its rotary motion and to cause the pivotal axis of the said head to tilt to a predetermined shaving angle when said head is rotated to a position transverse of said post.
