ATTORNEY.
Patented Apr. 6, 1937 UNITED STATES PATENT OFFICE Application September 4 Claims.
This invention relates to improvements in writing implements and is directed more particularly to improvements in pens.
The principal objects of the invention are directed to a writing pen which is characterized by novel means to facilitate not only the ready and easy removal of the pen point for cleaning or replacement but the accurate positioning of the pen point and feed member relative to one another and relative to the holder. The novel features of the invention are adapted for use in connection with pens of various types such as fountain pens and the like.
Numerous and various other novel feature and advantages of the invention will be hereinafter more fully referred to in connection with the accompanying description of the preferred form of the invention, reference being had to the accompanying drawing, wherein:
Fig. 1 is a side longitudinal elevational view through a pen embodying the novel features of the invention;
Fig. 2 is an elevational view of the feed member of the pen shown in Fig. 1;
Fig. 3 is a longitudinal sectional view through the pen point of the pen shown in Fig. 1;
Fig. 4 is a plan View of the holder of the pen shown in Fig. l with the pen point removed.
Fig. 5 is a sectional plan view on the line 5--5 of Fig. l with the propeller omitted;
Figs. 6 and 7 are elevational and plan views respectively of the thrust washer of the pen shown in Fig. 1; and
Fig. 3 is an inverted plan view of the feed member shown in Fig. 2.
Referring now to the drawing more in detail, the invention will be fullydescribed.
In a general way the pen has relatively rotatable parts such as a holder 2, a holder extension member 4, pen point 6 and feed member 8 which is reciprocable in one of the members by relative rotation thereof to facilitate separation of the pen point and feed member or to secure the pen point to the pen. The feed 40 member co-operates with the pen point to hold a supply of ink and in the case of a fountain pen the feed member may supply the pen with ink in the well-known manner.
The holder 2 preferably shaped for gripping between the fingers has a longitudinal bore therethrough in which the feed member 8 is reciprocable. The bore and feed member 8 are generally round in cross section except for means 55 associated therewith to prevent rotation of the 12, 1935, Serial No. 40,300
feed member 8 in the bore as will be later explained.
The upper end of the bore of the member 2 is provided with a longitudinal spline such as 12 to slidably receive a pin [4 on the feed member 3. The lower part of the bore is provided with a flat surface or surfaces such as l6 (see Fig. 5) which correspond to fiat sides l8 at the lower end of the feed member 8 (see Figs. 2 and 8).
These angularly disposed sides prevent rotation of the feed member 8 Within the bore of the holder and yet allow the desired reciprocation of the feed member 8 but other means may be provided to accomplish the same purpose if desired. The lowermost part of the borein the holder is preferably round as shown at I! in Fig. 5.
The pen point 6 has an opening 20 adjacent its lower end adapted to receive the pin [4 of the feed member 8 and a portion 22 of the pen point is offset from the main body thereof to have a projection as shown. This may be accomplished by merely upsetting the metal of the pen point or providing splits between which the pen body is struck up. I I
The projection or ridge 22 is adapted to cooperate with the spline I2 of the bore of the holder to position the pen point relative thereto and steady it. As will be seen, the upper part of the bore of the holder may be enlarged as at 24 to receive the lower end of the pen point 6 when the feed member 8 is positioned in the holder in writing position, shown in Fig. 1.
A propeller in the form of a screw member 26 is in threaded engagement with a threaded socket 28 in the lower end of the feed member and it has associated therewith a collar 30 which is small enough in diameter to rotate freely in that part of the bore which is provided with the flat sides.
A thrust washer 32 is disposed in the bore of the holder 2 below the collar 30. As shown in Figs. .6 and 7, this washer preferably has flat sides 34 engageable with the flat sides [6 of the bore and is provided with an opening 36 therethrough to rotatably receive a stem or spindle 38 which extends downwardly from the collar 30 of the propeller.
The member 4 is preferably formed as a handle or extension of the holder and has a socket 4|] to receive the lower end of the spindle 38. A pin 42 may extend through the spindle and extension 4 so that the outer extension or handle of the pen will upon rotation rotate the spindle 38 and collar 30 and threaded parts 36 thereof. The parts are so made that the parts 2 and 4 are held against separation but may rotate relative to one another but other means than that shown may be employed for that purpose.
As has been stated, the feed member 8 is reciprocable in the holder 2 and is prevented from rotation relative thereto by such means as the flat surfaces at the lower end thereof which operate with the flat sides of the holder member 2.
By rotating the holder extension or handle 4 in one direction or the other the propeller screw member 26 is rotated so that its screw part acts on the feed member 8 to raise or lower it relative to the member 2. In Fig. 1 the feed member 8 is shown in its lower writing position with the pen point 6 thereon and having its lowerend within the bore of the holder 2 and in writing position.
To remove or release the pen point 6 from the member 8, the part l is rotated in such a direction relative to the part 2 as to elevate the feed member 8 until the lower end of the pen point 4 is above the upper end of the part 2. In such a position the pen point 6 may be readily removed from the feed member 8 to facilitate the substitution of a new pen or the pen point, or to aid the cleaning of the parts.
When it is desired to affix the pen point to the pen it is positioned on the end of the member '8" with the pin i l thereof in the opening 20 of the pen point. Then the part4 is rotated in such a direction as to cause the feed member 8 to be moved downwardly of the part 2 drawing the lower end of the pen point into the bore of the holder.
The projection 22 in co-operation with a longitudinal slot l2 in the bore of the holder tends to prevent the pen point from shifting and therefore the pen point is held rigidly against movements relative to the holder and feed member.
From theforegoing it will be observed that the member 8 called the feed member is reciprocable by relative rotation of the parts 2 and 4 thus making it possible to easily and readily secure the pen point in place or release it for renewal or other purposes.
While I have described the invention in great detail and with respect to a preferred form thereof, it is not desired to be limited thereto since many changes and modifications may be made therein without departing from the spirit and scope of the invention. What it is desired to claim and secure by Letters Patent of the United States is:
