PATENT OFFICE.
LUIGI TADDEO, 0F CLEVELAND, OHIO.
FOUNTAIN PEN.
Application filed May 13,
To all whom it may concern.
Be it known that I, LUIGI Tnnnno, a citizen of the United States, and resident of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Fountain Pens, of which I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.-
This invention pertains to a new and novel construction of fountain pens.-
The prime object of the invention is to provide a simple, durable, novel, and eflicient construction of fountain pen with means whereby the amount of ink contained in the pen may be. materially increased, in connection with concealed means for filling the pen which are easily and readily operated and occupy comparatively little space within the body of the pen.
A further object of the invention is to so construct the pen with detachable means so positioned within its hollow body, after filling, that said means can be readily connected with means for filling the pen when desired.
Another object of the invention is to provide means within the body of the pen for insuring the easy operation of the plunger rod. when pushing the same through the plunger, either into or out from the casing.
The foregoing and such other objects as may appear from the ensuing description are accomplished by the construction, ar-
' rangement, location and combination of parts hereinafter more fully described, illustrated by the accompanying drawings, and more particularly setforth in the claims appended hereto.
In the accompanying drawings forminga part of this specification, it will be seen that:
Figure 1 is a central longitudinal section of the device embodying my invention, showing the plunger drawn back within the body of the pen to fill the reservoir with ink, and
Fig. 2 is a similar view showing the plunger at the front end portion of the body of the pen ready to be drawn back to fill the reservoir with ink.
Similar characters of reference are employed to designate like parts in the draw- 111 s.
"in the embodiment of my invention as Specification of Letters Patent.
Patented Mar. 14, 1922.
1921. Serial No. 469,366.
illustrated, A indicates the hollow body or casing of the pen, B the plunger reci rocable therein, and provided with a screw-threaded socket C formed within the lower or inner face thereof; D, is the reciprocable plunger rod formed with an enlarged inner terminal end portion E, said end being screw-threaded and adapted to engage with the socket C, so thatwhen said rod is connected to the plunger it can be drawn back and forth within the hollow body or casing.
By reference to Fig. 1, it will be seen that plunger is shown drawn back into the position it is caused to assume after the reservoir has been filled with ink. In this view the rod D has been detached from the plunger B, and pushed back into the reser- V011 so that a cap H, can be attached to the outer end of the hollow body or casing A, while in Fig. 2, the plunger is shown pushed forward by the plungerrod to the filling position, so that when drawn back it will fill the reservoir with ink.
I indicates a hard substance such as an ivory sleeve or ferrule with a central guide opening formed therethrough to permit the rod D to slide smoothly through the head J of the body or casing.
' The body of the plunger is formed of ivory or other hard material unaffected by the action of ink and is so constructed and fitted within the hollow body or casing as to prevent air from entering the reservoir, and i to prevent the ink passing therefrom.
A resilient ring or band K, is fitted within a groove L, formed in the periphery of the plunger and adapted to make an air-tight contact with the walls of the reservoir and a resilient washer M, formed of soft rubber encircles the plunger rod and is enclosed within a recess N formed in the upper or outer face of said plunger.
A. disk 0, of hard material is rigidly secured in contact with the outer face of the soft rubber washer M, and the inner face of the soft rubber washer rests in contact with the upper recessed face of the plunger, the lower face of said disk being provided with a convex recess Q, while the upper face of the plunger is formed with a concave recess P, thereby permitting the washer M to yield as the plunger rod moves back and forth through the plunger and at the same time forming an air tight connection between said soft rubber washer and the plunger rod.
The upper or outer terminal end of the plunger rod is provided with a knob R, or
other suitable means convenient for grasping with the fingers.
The enlarged inner terminal of the plunger rod renders it impossible to withdraw said rod outwardly through the plun er or through the head of the hollow bo y or casing. I
It will be perceived thatthe rod D can bereadily detached from the plunger and positioned within the'hollow body or casing A, after filling,as clearly shown in F ig. 1 that it is quite easy and convenient to-turn the rod D so as to thread its terminal threaded end within the socket C, when it is desired to operate the plunger for filling the pen.
4 lt'will also be obvious-that the recessed portions P and Q are important for insurlng the easy operation of the Plum er man,
when pushing the same through t e plunger,
either into or out from the casing 'A, since the fit of the Washers, is not tlght, butvjust comfortable so that an easy movement of the plunger rod through the soft rubber washer M will be assured, due to the provision of said recesses P and Q which allows for the proper yield-- in movement of said washer:
I claim and desire to secure by Letters Patentis: V 7
1. A fountain pen comprising: 'ahollow body, a reciprocable plunger mounted therein formed from a single piece of hard material having a recessed upper face adapted to I thesoft rubber washer,
ger beneath said soft lunger rod in'"the' several aving thus described my "invention what 1, testimony retain a soft rubber washer with a screwthreaded socket formed in its lower face and an annular recess formed within its body portion, a resilient packing ring fixedly secured within the said annular recess, a disk 40 of hard material secured within said recessed upper'face in contact with the upper face of and a plunger rod formed with an enlarged screw-threaded inner terminal adapted to detachably engage with said socket.
' 2. A fountain pen comprising a hollow .body, a plunger therein formed from a single piece of hard material havin a recessed upper end to receive a soft rub er washer w th a screw-threaded socket formed within its lower face and an annular recess formed 'within its body portion, a central concave whereof, I- hereunto set my hand this 28"; day'of Mch., 921,
I LUIGI TADDEO.
In presence of' i WM. -M. Mormon, V Son W. WrMAN.
