SEGMENTAL PUMP LEVER FOR USE WITH DRIVING MEANS OF DIFFERENTLY CONSTRUCTED ENGINES 2 Sheets-Sheet 1 Filed April 6, 1946 w un III Mama/s KA 7095?.
wwz/az ATTORNEY INVENTOR Mom/s K? rah Ea BMW I ATTORNEY M. KATCHER SEGMENTAL PUMP LEVER FOR USE WITH DRIVING MEANS OF DIFFERENTLY CONSTRUCTED ENGINES 2 Sheets-Sheet 2 May 9, 1950 Filed April 6, 1946 and 33. Readily removable pin 13 passes through removable segments 35 and 36 and arms 37. Pi
I3 is readily removed when spring clip 13, Fig. 8, is pulled out from under its head. Arms 31 are provided with punched out tongues or projections 43 against which prongs 38 bear when segment; 35 i caused to rock or swing in a clockwise direction. A clip M has a hooked portion 45 which bears on sleeve 4!. It also has two lugs 46 which enter corresponding openings 95 in arms 3?, see Figs. 1, 3, 8 and 11. Tongue 41 on clip i4 receives the lower end of spring 48, the upper end of said spring reacting against the pump casing 15. Removable lever segment 35, Figs. 1 and 2, is provided with a cup 49 for receiving the upper end of actuating bar l2, the latter reciprocating in guide 53. The lower end of bar l2 rides on cam fixed on motor shaft 52.
When bar It moves up, removable segment 35 interlocks with standard segment 33 turning it clockwise, prongs 38 bearing down on tongues 43, prongs 33 bearing up against and rotating about sleeve M, and the main body of segment 35 pushing up on pin 13. Under pressure of spring 48 and as cam 5| rotates and lets bar l2 come down, removable segment 35 interlocks with standard segment 33, by means of pin l3 and sleeve 41, turning it counterclockwise, clip l4 bearing down on pin 13, its lugs 43 bearing down on arms 31 and tongue 45 bearing down against and rotating about sleeve 4|.
The inner end of standard lever segment 33 is provided with anotch in each of its arms 31 by means of which it engages pin 53 set through stem 21, an arm 31 coming on either side of said stem.
When the operating lever, comprising interlocked segments 33 and '35, rocks in a counterclockwise direction, the inner end of segment 33 pushes up on washer or ring 3i, which, through the intermediacy of spring 32, raises diaphragm 20 for its compression stroke. Spring 32 has a predetermined amount of initial compression.
When the operating lever rocksin a clockwise direction, the inner end of segment 33 solidly presses down on pin 53, efiecting the suction stroke of the diaphragm. In Fig. l, diaphragm 2B is at the upper limit of its stroke. This means that the pressure in fuel pump chamber 54 and K outlet 55, which is connected to the carburetor by a fuel line, both the carburetor and the fuel line not being shown, is lessthan that required for spring 32 to yield, and that pin 53 is in contact with segment 33. pump chamber 54 in a subsequent compression stroke of diaphragm 20 be great enough to overcome the initial compression in spring 32, the inner end of segment 33 will rise without corresponding rising of stem 21, so that pin 53 will be located below the lower edge of said segment. In other words, there will be lost motion between segment 33 and stem 21. Under this condition, upon subsequent clockwise motion of the operating lever, which of course includes segment 33, there will not be any pull upon stem 2? at the beginning of the rotation of said segment, the latter catching on pin 53 only toward the end of the stroke. The reciprocation of diaphragm 20 by the operating lever through the intermediary of a spring, such as spring 32, is also described in my applications Serial Nos. 500,782, 633,333 and 644,535.
Fastened to the top of cover 22 at gasket 56, is glass strainer bowl 51 which is held in place by Should the pressure in fuel r the engagement of bail 58 with lugs 59 on the cover. Bail 58 presses bowl 5! down on gasket 56 through the intermediacy of bolt 50, nut 51 and cap 52 as is well known in the art.
The pump and lever of Figs. 8, 9 and 10 illustrates the case where the same type of pump as is used in Figs. 1 and 2 can be used elsewhere to suit a different type of motor with a different relative position of its cam shaft II. The only difference between the pump of Fig. 1 and the pump of Fig. 9 is in the removable lever segments 35 and 36. The construction and action of all the other parts is the same as that described before for Fig. 1. Segment 36 is formed with an angle between its portion having prongs 33 and 33 and its portion having bridge piece 72, the latter riding on cam 5|, the pressure of spring 48 holding it there.
In Figs. 5, 6 and '7, both the standard lever segment l4 and the removable lever segment 15 differ from the corresponding segments shown in Figs. 1 and 9. The standard lever segment is formed of two arms '16 held together by rivet 8|, the notched inner end of said arms straddling stem 2'! and being adapted to engage pin 53. Arms 16 are pivotally mounted on sleeve 4|. Removable segment !5 is formed of two arms 18 having between them a spacer block 85, all three parts being held together by rivets l9 and 80. The inner end of segment 15 is provided with a pair of upper prongs 83 and a pair of lower prongs nappies el said prongs-straddling sleeve 41 and providing segmentlS with a rotating fit thereon, Prongs '83"and84 interlock with-punched out bulge or projection 82 on arms 16. A lug Bti'sprovided on spacer block 85 for receiving the bottom of spring" 48. Removable segment 15 is pinned to standard segment it by removable pin 81, the latter being kept in positionby spring clip 88 under its head.
