PEN AND FEED rnsirnn.

Specification of Letters Patent.

Patented Septli, 1920.

Application filed September 3, 1919. YSeriaI No. 321,367.

To all whom it may concern:

Be it known that I, Bnoon B. BRADFORD, a citizen of the United States, residing at Hot Springs, in the county of Sanders and State of Montana, have invented a new and useful Pen and Feed Pusher, of which the following is a specification.

The device forming the subject matter of this application is adapted to be em ployed for assembling the point and the feed of a fountain pen with a portion of the pen barrel and one object of the invention is to provide a novel jaw construction, whereby the pen and the feed member may be held during the mounting thereof on the barrel or body of the pen. 7

The invention contemplates the provision of a device of the kind mentioned which may be used readily in connection with fountain pens of different sizes and makes.

It is an object of the invention to supply a structure which will grip the parts tobe assembled, without imparting injury there to and without subjecting the fingers of the operator to injury.

A further ob'ect of the invention is to improve and to simplify generally, devices of that sort to which the invention appertains.

VVith' the above and other objects in view, which will appear as the description pro ceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, with in the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings -Figure 1 shows in side elevation, a device constructed in accordance with the invention; Fig. 2 is an elevation wherein the device is viewed at right angles to the showing of Fig. 1; Fig. 3 is a section taken approximately on the line 3-3 of Fig. 2, looking in the direction of the arrows; and Fig.

1 is a fragmental elevation, similar to Fig. 1, but showing the spring arranged differently from the disclosure in Fig. 1.

In carrying out the invention there is provided a support which may be variously constructed. In the present embodiment of the invention, the support includes a base 6, carrying a standard 5, the base having an L-shaped extension 50 in which a screw 8 is threaded, the screw carrying a foot 7. Obviously, the support above defined may be mounted on the edge of a table Tor like object, the same being clamped between the base 6 and the foot 7 of the screw 8. The standard 5 is offset, laterally, as shown at 51, to permit the formation of a recess 9 in the standard. The recess is closed at one side by the offset portion 51 of the standard, the opposite side of the recess being open, as shown in Fig. 1. The forward end of the recess 9 is open, whereas the rear end of the recess is closed by va part 52 of the standard 5. Projections 16 extend from the standard 5 and have functions which will be pointed out hereinafter.

Jaws 10 are located in the recess 9 of the standard 5 and are mounted therein for a limited longitudinal movement, and for a limited transverse movement toward and away from each other. One of the jaws 10 is supplied adjacent its forward end with a laterally projecting operating piece 23. in order to connect the jaws 10 and to guide them in their transverse movement, toward and away from each other, a pin 18 is carried by the inner edge of one jaw, and is received slidably in an opening 180 formed in the inner edge of the other aw.

Forward links 150 and rear links 15 are provided, the outer ends of the links being pivoted at 53 to the standard 5, the inner ends of the links being pivoted at 54 to the respective jaws 10. The invention comprises a spring, including oppositely proecting arms 17 and an intermediate coil 18' connecting the arms. hen the spring is arranged as shown in 1, the coil 18 bears on the links 150, near to theinner ends thereof. the arms 17 hearing against the projections 16 on the standard 5. The numeral 2O denotes a screw mounted in the part 52 of the standard 5 but not threaded therein. A nut 22 is threaded on the screw 20 and is ada ted to bear against the part 52 of the standard. At its inner end, the screw 20 is supplied with a transverse head 31, the ends of which are slidably received in correspondingly shaped openings 58 formed in the inner edges of the aws 10.

Gripping plates 55 are provided, the same being fashioned from rubber or other suitable material. Any material may be employed in the formation of the gripping plates 55, but the material should be selected with a View to avoiding the marring or other and, in operation,

damaging of the pen point and feed which are to be manipulated. The gripping plates 55 are dovetailed at 56 to the jaws 10, and are disposed at an angle to each other, as shown in Fig. 3, the plates being suitably shaped, as shown at 60, so as to receive the pen point and the feed member.

The spring l7-l8 tends to advance the jaws 10 in the direction of their length, and to separate them, the jaws being carried, it will be recalled, by the links 15150. The pen point and the feed member are inserted between the jaws 10 and, more specifically, between the gripping plates 55, the jaws being slid rearwardly by finger pressure exerted upon the operating piece 23, the action of the spring 17-1S being overcome in this way. Continued rearward pressure upon the jaws 10, exerted by the pen in the process of assembling, will cause the jaws to grip the pen point and the feed, and the more strong the thrust exerted on the pen, the more strongly will the jaws grip the pen point and the feed. It will be clear that, by spacing the nut 22 from the part 52 of the standard, the opening movement of the jaws, under the action of the pring 1718", may be adjusted for pens of different sizes and makes.

It is not mandatory that the spring 17- 18 be arranged as shown in Fig. 1. Thus, if desired, as depicted in the modification shown in Fig. 4, the pring may be reversed, the outer ends of the arms 17 of the spring bearing on the outer ends of the links 150, the coil 18 of the spring bearing on the inner ends of the links 15. When the spring is located as above described, the spring 10 tends to move the jaws 10 toward each the jaws 10 are separated, before the pen point and the feed are inserted therebetween, by a pull exerted on the part 28*.

The device forming the subject matter of this application is simple in construction and embodies few parts et out of order and the to appreciable wear are the gripping plates 55. The construction, obviously, is such that the gripping plates may be removed and renewed at any time.

Having thus described the what is claimed is In a device of the class described, a support; a pair of cooperating jaws; and links connecting the jaws with the support for longitudinal and transverse movement.

2. I11 a device of the class described, a support, a pair of cooperating jaws; links connecting the jaws with the support for longitudinal and transverse movement; and spring means for moving the jaws transversely with respect to each other.

In a device of the class described, a support; a pair of cooperating jaws; links connecting the jaws wit-h the support for longitudinal and transverse movement; and adjustable means for limiting the opening movement of the jaws.

4. In a device of the class support; a pair of cooperating connecting the jaws with the support for longitudinal and transverse movement; spring means for moving the jaws trans versely with respect to each other; and means for limiting the opening movement of the jaws.

5. In a device of the class described, a support; a pair of cooperating jaws; renewable gripping members removably mounted on the jaws; and links connecting the jaws with the support for longitudinal and transverse movement.

In testimony that I claim the foregoing as my own, I have hereto vaflixedmy signature in the presence of two witnesses.
