FOUNTAIN PEN, LEVER FILLER Filed July 20, 1928 E. c. FRANZMANN 7 1,751,855
Patented Mar. 25, 1930 UNITED STATES PATENT OFFICE I FOUNTAIN PEN, LEVER FILLER Application filed-July 20, 1928. Serial N0. 294,183.
lever filler fountain pen in which the parts are simple, durable and easy to manufacture,
and easily and cheaply connected to the easing of the pen,'and which in operation cause the rear end of the presser to be forced downwardly against the rear end of the sack first during the compressing operation and thus more efliciently emptying the sack of ink.
The object of the invention is further to provide a support for the lever whichcan be attached to the casing of the pen without drilling any holes or attaching any pieces to the casing, the pivotal support for the lever comprising an arcuate fiat metal band which is positioned in an annular groove in the inner wall ofthe casing, said pivotal support being made ofa fiat spring band.
' Another object of the invention is to pro- 'vide a construction whereby the sack may extend the full length of the interior of the casing, as there are no parts interposed between the inner end of the sack and the rear end of the casing, and also the object of the invention is to provide a pen of the character set forth in which the presser bar extends almost the entirelength of the sack to within a quarter of an inch of the sack holder.
To these ends the invention consists in a lever filler fountain pen constructed as hereinafter set forth in the specification and particularly pointed out in the claims.
Referring to the drawings Figure 1 is a side elevation partly in section of a fountain pen embodying my invention.
Fig. 2 is an enlarged sectional elevation illustrating the presser lever in closed position.
Fig. 3 is a sectional elevation similar to Fig. 2 with the presser lever in its open position.
Fig. 4 is an enlarged sectional elevation 50 taken on line 4 -4 of Fig. 2.
Fig. 5 is a sectional elevation taken on line 5-5, Fig. 2, and
Fig. 6 is a sectional elevation taken on line 66, Fig. 2.
2, 3, 5 and 6 are broken away.
Like numerals refer to like parts in the several views of the drawings.
In the drawings, 10 is the casing of the pen, 11 the sack holder and 12 the sack.- 13 is the presser for the sack. 14 is the presser lever and 15 the arcute support for the presser lever and constituting a pivot therefor. The arcuate. support 15 is preferably made of spring 1 steel and extends around the bore of the casing 10 in an annular groove 15', as illustrated most clearly in Fig. 4.
The presser lever 14 is U-shaped in cross section, see Figs. 4 and 5, and has a spring 16 clamped thereto at its rear end by the flanges 17 and 18 of the lever 14, being turned inwardly. The forward end of the lever 14 has oppositely disposed ears 19 extending laterally therefrom and projecting under in-' wardly turned flanges 20 of the presser 13. The arcuate support 15 projects between the lever '14 and its spring 16 and being flat it causes tension to be applied to the spring 16 and contacts with said spring when the lever is moved from its closed position, Fig. 2, to its open position, Fig. 3, while compressing the sack 12.
The lever 14 normally lies longitudinally of the casing 10 within a slot 21 provided in the wall of said casing and the forward end of the lever 14 is flattened at 22, so that when the lever is in the position illustrated in Fig. 3 it will be held in that position by the spring 16 and by the flattened end 22 bearing against the presser 13. The lever 14 is provided on its opposite side flanges with notches 23 through which the arcuate support 15 projects.
The general operation of the mechanism hereinbefore specifically described is as follows :Assuming the different parts to be in the positions illustrated in Figs. 1 and 2, and that the sack is to be compressed, the right hand end of the lever, Fig. 2, or the rear end thereof, is lifted untilthe lever assumes the position illustrated in Fig. 3. During the 0 first part of this motion the rear end of the presser 13 is depressedand then upon further movement of the lever the sack is compressed from the rear end toward the front end. This compressionof the sack from the rear toward the front end is very desirable in devices of this character so that the air and ink will be sure to be forced out of the sack and not pocketed therein and this result is attained by the arrangement, relative location and operation of the lever, the presser and the pivotal support 15 for the lever.
When the lever '14 is moved from the position illustrated in Fig. 2 to the position illustrated in Fig. 3, the spring 16 will be bent to impart tension thereto, due to the fact that the support 15 is a flat strip of spring metal of substantially greater width than its thickness, so that as the lever is moved from the closed to the open position, the spring will be moved away from the lever as illustrated in Fig. 3, thus increasing the tension and firmly positioning the lever in its open position with the flat end 22 bearing against the presser 13. The ears 19'upon the lever 14, while they are pivotally connected to the presser, are at the same time'free to move longitudinally of the presser during the opening and closing movement of the lever, 'so that the presser may be moved straight across and not longitudinally of the pen casmg.
