FOUNTAIN-PEN.

Specification of Letters Patent.

Patented May 16, 1916.

Application filed January 15, 1916. Serial No. 72,293.

To all whom it may concern:

Be it known that I, OLIVER A. Monnow, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Fountain-Pens, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in fountain pensand has relation more particularly to that type which are designed to contain within themselves means for filling the same, and it is an object of the invention to provide a pen having novel and improved means whereby the reservoir may be readily and effectively compressed in order that a vacuum may be created so that when the wall of the reservoir assumes its normal position, ink will be drawn in through the open end of the reservoir.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved fountain pen whereby certain'important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure l is a View partly in section and partly in elevation illustrating a fountain pen constructed in accordance with an embodiment of my invention, the reservoir being shown in its normal position; Fig. 2 is also a view partly in ,elevation and partly in section illustrating the pen as disclosed in Fig. 1, with the reservoir compressed; Fig. 3 is a view in perspective, detached, of the elongated plate or shoe herein embodied; Fig. 4: is a view in perspective, detached, of

the operating member for the plate or shoe as herein included; Fig. 5 is a view in perspective, detached, of the spring member herein employed as coacting with the plate or shoe; and Fig. 6 is a view in perspective, detached, of the retaining block as herein disclosed for maintaining the spring in applied position.

As disclosed in the accompanying drawings, 1 denotes the barrel of my improved fountain pen which supports or carries in any desired manner the usual pen stock or nozzle 2, which in turn is provided with a passage 3 for thewriting fluid. The passage 3 communicates with the pen l and the feeder bar 5 in the usual way, and the upper or inner end of the stool: or nozzle 2 is provided with a reduced portion or neck (3 to which the compressible reservoir 7 is connected. said reservoir being preferably formed of rubber.

As herein embodied, the reservoir 7 is of such a length as to terminate a predetermined distance inwardly of the closed end 8 of the barrel 1., and the wall of the barrel 1 immediately adjacent the inner end of the reservoir 7 is provided with the elongated slot 9 in which is pivotally supported, as at- 10, the lever 11 which, when the reservoir 7 is in its extended or normal position, is substantially entirely confined within the slot 9.

The pivoted end of the lever 11 is provided with the inwardly disposed arm 12 disposed through the longitudinally disposed slot 1d produced in the inner end portion of the elongated plate or shoe 15, and the free extremity of said arm 12 is provided with the cross head 16, whereby said arm 12 is held against complete withdrawal from the slot 14 and which overlies the outer face of the plate or shoe 15 in order to force said plate or shoe in a direction toward the reservoir 7 so that said reservoir will be compressed or collapsed, whereby a partial vacuum is caused and when the reservoir '7 is allowed to expand, the pressure of the outside atmosphere will force the ink within the reservoir through the passage 3.

The plate or shoe 15 extends from a point in close proximity to the stock or nozzle 2 to a point beyond the outer end of the slot 9, and the portion of the plate or shoe 15 beyond the inner end of the reservoir 7 and with which the cross head 16 coacts, is disposed on a predetermined inward incline and terminates at its inner end in the pocket 17 adapted to receive the cross head-16 which serves to automatically lock the arm 12 and the lever 11 against return movement.

Snugly fitting within the barrel 1 at its closed end, is the block 18 provided in its periphery with the oppositely dispos d notches 19, and disposed within one of said notches 19 is the outer end of the fiat spring 20, said outer end of the spring 20 being provided with the angular extension 21 overlying the under face of the block and terminating in the inwardly disposed lip 22 fitting Within the second notch 19. By this arrangement it' will be perceived that the spring 20 is efiectively locked in applied position.

The inner end of the Hat spring 20 is secured to the plate or shoe 15 substantially midway the length thereof and when the lever 11 is adjusted into closed position, said spring 20 serves to withdraw the plate'or shoe 15 away from .Jl16 compressed or collapsed reservoir 7,.so that said reservoir may expand or return to its normal position with a minimum of resistance. It is also to be observed that the free extremity of the inclined portion of the shoe or plate 15 is bent to afford a shoulder 23 which is engaged by the cross head 16 when the lever 11 is in its inner or closed position and serves to maintain the lever in such position.

\ From the foregoing-.description, it isthought to be obvious that a fountain pen constructed in ac ordance with my inveu tion is of an extremely simple and com paratively inexpensive nature and is particularly. well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

I claim 1. In a self-filling fountain pen, the com- Copies of this patent may be obtained for five cents each, by addressing the bination with a barrel having an elongated slot adjacent one end and a collapsible reservoir therein, a plate associated With the reservoir and located on the side of the reservoir opposite to the side adjacent the portion of the barrel provided with the slot, one end of said plate extending beyond the reservoir and overlying the slot of the barrel, said extended portion of the plate being provided with a longitudinally disposed slot, a lever pivotally mounted Within the slot in thebarrel, an inwardly disposed arm carried by the lever and extending through the slot of the plate, and a cross head carried by the arm eugagingthe face of the plate opposite to the reservoir.

2. In a self-filling fountain pen, the combination with a barrel having an elongated slot adjacent one end and a collapsible reservoir therein, a plate associated with the reservoir and located on the side of the reservoir opposite to the side adjacent the portion of the barrel provided with the slot, one end of said plate extending beyond the reservoir and overlying the slot of the barrel, said extended portion of the plate being provided with a longitudinally disposed slot, a lever pivotally mounted within the slot in the barrel, an inwardly disposed arm carried by the lever and extending through the slot of the plate, and a cross head carried by the arm engaging the face of the plate opposite to the reservoir, said plate. being provided with longitudinally spaced shoulders adapted to be engaged by the cross head of the arm whereby the lever is locked at the limit of its movement in either direction. In testimony whereof I hereunto affix my signature in the presence of two witnesses.
