JOHN SCHROEDER, 0F DAVENPORT, IOWA.
KOTOR.
T o alllwkoin t may concern:
. .Be it known that I, JOHN SCHROEDER, a
citizen of the United States, and aresident o f the city of Davenport, in the county of Scott andl State of Iowa,lhave invented a new and Improved Motor, of which'the following is a full, clear, and'exact description. This invention relates to improvements in motors, and more particularly to motors of the character disclosed in Patent No. .873,619 granted to me December 10th, 1907 and in january 5th, 1909, an object of the invention being to provide improved valve operating mechanismA operated by .the piston rod of the motor.
A furth robject is to provide a valve operating m chanism which is quick operating and which most eiliciently performs the funcv tions for which it is intended.
With these'and other objects in view, the invention consists in certain novel features ofconstruction and combinations and arrangements of parts as will be'more fully' hereinafter described and pointedout in the claims.
In the accompanying drawings 1- Figure 1 is a view in elevation illustrating to a .washing machine.
Fig. 2 is a view in end elevation. Fig. 3 isa top -plan elevation. Y
Fig. 4 is an enlarged view in vertical longitudinal section through the motor cylinder.
Fig. 5 is a fragmentar view similar to the left hand end portion o Fig. 4 showing the valve in reversed position.
Fig.- 6 is a view in longitudinal section.
through the valve casing showing the valve in elevation.
Fig. 7 is a view in elevation of the valve.
I have illustrated my improved motor as applied to a washing'machine although it is obviously capable of many other uses.
1 represents the casing of thefwashing machine, having an agitator shaft 2 projecting through its top 4 and thelatter is provided with a stuiling box 3 to render the same water tight.
A motor bed 5 is secured on the top 4 and provided at one end with a post 6 to which the head 7 of a moto'r cylinder 8 is pivotallyf connected.- A reciprocating piston 9 is lo- Specication of Letters Patent. Patented Ag. '31, 192() Application me@ January 31, 1920. serial No. 355,390.'
cated in the cylinder 8 and ports and 11 'are provided in the cylinder heads 7 and 12 at the ends of the' cylinder.
The head 7 has a conical bore forming a f chamber 13 for a conical/rotary plug valve 14. The port 10 communicates directly with the valvechamber 13 and a passage 15 is provided longitudinally of the cylinder 8 connecting the port 11 with the valvecasing.
The valve 14 is made with recesses 16 and 17 in opposite sides and the said recess 17 communicates with an outlet passage 18 exof the valve casing and provided with a discharge nipple 2O for the attachment of a hose (not shown) for conveying the exhaust to any convenient point of escape. l
- An inletor supply pipe 21 discharges into the valve casing through a port 22 registering with the recess 16 and a cock 23 is provided in the pipe 2l to control the flow of water, or other motive fluid.
The stem 24 of the valve 14 is` projected through a stuffing box 25 and a coiled spring tending to the end ofthe valve and commul nicating with a cup 19 screwed onto the end' 26 is'located around the stem and exerts suficient pressure on the valve to maintain the valve in operative pos1t1on.
The piston` rod 9 which is reciprocated vby the piston 9 is secured toa rack 27, the
latter guided in`its movement by a bracket 27 on the engine bed 5. f The rack 27 meshes with a pinlon 28 fixed to shaft 2, above'the pinion 28 and 1s provided with an upwardly projecting crank pin'30. A coiled spring y31 connects the crank pin' 30 with a vertical post 32 on the bed 5 and a rod 33 is also pivotally connected to the crank pin 30 and is longitudinally movable through an opemng 34 1n the post 32. A coiled sp1-ing 35 appreciably weaker than spring 31 is located around the rod 33 between the post 32 and a fixed but adjustable-collar 35 on the rod to cushion the movement of the crank pin 30 and disk the rod 37 and adjustable collars 40 are secured on the rod 36 and spaced apart at opposite sides of the pin to give the necessary lost motion to the rod.
The disk 29 is made with a segmental hub 41 which is engaged by a crank pin 42 on shaft 2 to move the same as will now be described.
The operation is as follows: .With the parts as shown in the drawings the piston 9 and rod 9 are just be inning their movement toward the left. T e rack 27 will turn pinion 28 and impart motion to the shaft 2. The 'disk' 29 lwill remain stationary until the crank pin 42 iengages the end of hub segment 41 when it will turn the same, expanding spring 31. Just as the piston reaches the end of its stroke, the crank pin 30 will be carried past the center line of ypost 32 and shaft 2, and the spring 31 will contract, imparting a quick partial turning movement to the disk 29 vand in so doing will cause the rod 37 to move the crank arm 38 to reverse the valve 14. The collars 40 being spaced apart permit the initial turning movement of the ydisk to move the rod 37 Without operating the valve as the valve is moved only by the spring 31.
Various slight changes might be made in the general form of the parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, butconsider myself at liberty to make such slight changes and alterations as fairly fall Within the spirit and scope of the appended claims.
I claim:
1. A valve gear, comprising a shaft, means for turning the shaft in opposite directions, a crank disk loose on said shaft, means on the shaft and disk compelling the disk to turn With the shaft during'a portion of thev rotary movements of the shaft in both directions, a spring operatively connected to the disk and compelling the latter .to complete its movements in both directions, a valve operating crank arm, and a rod connecting the disk and crank arm.
2. A valve gear, comprising a shaft,fmeans for turning the shaft in opposite directions, a crank disk loose on said shaft, means on the shaft and disk compelling the dis1r to turn with theshaft during a portion of the rotary movements of theshaft in both direc-- tions, a spring operatively connected to the disk andcompelling the latter to complete 1 `its movements in both directions, -a valve operating crank arm, a rod connecting the disk and crank arm, and a second spring cushioning the movements of the crank disk in both directions.
3. A valve gear, comprising a shaft, means for turning the shaft in opposite directions,
a crank disk loose on ,said shaft, means on the shaft and disk compelling the disk to turn With the shaft during a portion of 'the rotary movements of the shaft inboth directions, a spring operatively connected tothe disk and compelling the latter to complete its movements in, both directions, a valve operating crank arm, a rod connecting the ,disk and crank arm, a second spring cushof the shaft in both directions, a fixed post having an opening therein, a crank pin on the disk, a rod connectedto the crank pin and extending through theopening in the post, a spring on the rod located between the post" and a fixed part of the rod and cushioning the movement of the crank pin, a second spring connecting the crank pin and post and positioned tangentially to the disk so as to complete the movements of the crank disk in both directions after said movement is initiated by the shaft, a valve operating crank arm, and a rod connected at one end to the crank disk and at its other end having a loose connection with the crank 1' arm, said loose connection permitting a predetermlned movement'pf the rod before movlng the crank arm. v
5. A valve gear, comprising a shaft, means for turning the shaft in opposite directions, e
a crank disk loose on the shaft, a segmental hub on the'crank disk, .a pin on the shaft tween the post and a fixed part of the rod and cushioning the movement ofthe -crank pin, a second spring connecting the crank pin and post and positioned tangentially to the disk so as to complete the movements of Y the crank disk inboth directions after said movement is initiated by the shaft, ,a valve operating crank arm, and a rod connected at one end to the crank disk ,and at its other end having a loose connection with thel crank arm, said loose-connection permit ting a predetermined movement of the rod before moving the crank arm.
