' GUY G. WILKINSON AND MEAD HEDGLON, OF SYRACUSE, NEW YORK, ASSIGNORS 'IO SYRACUSE WASHING MACHINE CORPORATION; OF SYRACUSE, NEW YORK, A
CORPORATION OF NEW YORK.
PLUNGER-OPERATING MECHANISM.
To all whom it may concern: 1
Be it known that we, GUY G. WILKINSON and MEAD HEDGLON, citizens of the United States, and residents of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Plunger-Operating Mecha nism, of which the following, taken in connection with the vaccompanying drawings, is a full, clear, and exact description.
This invention relates to a plunger operating mechanism for washing machines, of
the general type disclosed in patent to Zuill- No. 1,021,498 embodying a vertically reciprocating plunger that imparts desired movements to the vacuum cup devices of the machine.
The main object of this invention is to provide mechanism for delivering power to the piston in a straight line conformingto the axis of the piston. This feature has many advantages in that it eliminates side thrusts from. the bearings in which the piston is operating, and even permits the use of the slngle bearing for the piston, should that be. desirable. l
Other objects relate more specifically to the arrangement and construction of the mechanism for eflecting straight-line movement of the piston such as simplification of the mechanism by the elimination of usually required parts, such as forinstance, equalizing devices, etc. K
Further, our invention provides an apparatus of simple construction and operation that is more easily assembled than those heretofore used and that eliminates prac-- tically all danger of the mechanism becoming out of alignment after being properly assembled.
Other objects and advantages relate v to the details of construction and form ofthe mechanism, all as will more fully appear from the following description, taken in connection with the accompanying drawings, in which Figure 1 is an elevation of the mechanism of our invention. q
Figures .2 and 3- are diagrammatic illustrations of the mechanism in difi'erent operative positions.
For the purpose of illustrating our invention, we have indicated a frame 1 which may be of any form and construction, pref erably from some portion ,of which mechanism hereinafter described is supported.
its'upper end upon pin '3- carried by or' formed in connection with the frame 1 of the machine. The main lever or walking beam L of the piston-operating Inechanism is hinged or pivoted at one end upon the pin 5 formed at 'the lower end of the swinging leg 2, and the opposite end of the lever 4 is formed with a yoke, the opposite walls 6- of which are formed with openings or journals for receiving respective trunnions 7 egitending at oppositesides of a trunnion block 8- mounted on the lower end of the piston 9 of the washing machine. Any suitable mechanism may be provided for securing the walls 6' in proper position with respect to the trunnions 7. actuated. for the purpose of reciprocating piston '9'by means of arpltman -10. mounted at its lower end upon a pin "11 formed in connection with the main lever 4 and at its upper end upon a pin -l2- formed in connection with a crank-arm 13-4 rigidly mounted upon the 14 of the washing machine.
It will be obviousthat as the main shaft 14 rotates the'pin 12- will travel as indicated in dotted line, Figure 1, carrying with it the upper end of the pitman 10-, thereby moving the main lever,4- about its pivot" 5., to raise and lower the plunger '-9. For the purpose of causing the main lever 4.- to deliver power to the piston or plunger -9- in a straightline conforming substantially to the axis of main shaft the plunger, a radiusbar 15 is rovided having one endfipivotally mounte upon a pin -16 which may be rigidly carried from any part of the machige so that it remains in stationary position during the end of the radius bar 15- is pivotally connected to the main lever 4 in any suitable manner and as shown,'one of the The main lever '4.- is
operation of the mechanism. The opposite m members, as for instance the radius bar 15 is provided with a pin 17 extending through the other member to'provide such a pivotal connection. n
It will be obvious from the disclosure that as the main shaft -14 rotates, carrying with it the crank-arm 13 and "pitman 1G that the main lever 4 will be raised and lowered to raise and lower the piston or plunger 9, and that as the main lever is raised and lowered, it will be caused to reciprocate by means of radius bar 15 to an extent sufficient to cause the application of power to the plunger 9 to be in a straight line conforming to the axis of the plunger. This movement of the main lever 4- is ermitted by reason of the fact that its p vot 5 is upon a leg 2 that is free to swing about the pin ,3 carried in .a stationary manner. by the main frame" the pivotal pin 5 for the'lever A is adapted to swing toward and from the plunger in substantially the same hori'zo'ntal plane as that ,of the pivotal stud 16 for the radius bar -15-- while the throw of the crank arm 13, which is connected to the lever 4- by of the pitman 10- is made to rock the lever -4-; upon its fulcrum -5 equal distances above and below the horizontal plane of the axis of the pivotal stud 16 of the radius barw15.
This radius bar 15- extends from its pivotal stud 16- toward the fulcrum 5 of the lever 4- and is pivoted to said lever at 17 between the pivots 5 and -11 and therefore, its pivotal pin 17 will travel throu h a vertical arc equal distances above an below the horizontai plane of the axis of the pivotal stud 16 as the lever and plunger 9 carried thereby are moved vertically by the crank arm 13- and pitman 10.
The length of the radius bar 15- depends upon tl1e-throw of the crank arm 13 and therefore, upon the movement of the lever --4- from one extreme position to another but is made to conform to the changing position of the pivot 5- with the link 2- under the condition that the piunger 9 is moved rectilinearly of its axis. For example, asuming that the plunger 9 is moved rectilinearly of its axis from the position shown in Figure 1, it is evident that as the adjacent end "of the lever 4 approaches the horizontal plane its opposite end connected to the lower end of the link 2- will be moved afshort distance to the right, and as the lvercontinues to move to its extreme upward limit,
- p the pivot 5 will be returned to its starting position through the same distance and it 18 this amount of movement of the pivot means 7 -5 which determines radial length of the bar l5 which is proportionate to the length and angular movement of the lever 7 That is, the arc of movement of the pivot- 7 ai pin 17- ofthe radius bar 15 which i fulcrumed at 16 in the horizontal plane of the pivot 5 is (if such radius as to cause the pivotal pin 7 to travel rectilin'early of the axis of the plunger 9 it 7 being understood that the middle ordinates of the arcs of movement of the pivotal pins 17- and 7 are also proportionate in that the middle ordinate of the arc of movement of the pin :17corresponds to the 8 .tween the pivot l7 and the trunnions The lower end of the link 2 carrying l7and the pivot of the walls 6 of 9 the yoke end of the lever, permitting eliicient operation with considerable economy of space and material.
specific Iconstrhction of mechanism and a particular form and arrangement of the parts thereof, as illustrative of a perhaps preferred embodiment of our invention, we do not desire to limit ourselves to the details i of form, construction or arrangement of the mechanism, as various changes may be made without departing from the invention as set forth in the appended claims.
We claim:

A plunger operating mechanism com- 1 prising in combination with a vertically movable plunger, a walking beam fulcrumed at one end to permit longitudinal movement of the beam and having its other end operatively connected to the plunger, a rotary no driving element movable about a fixed axis above the intermediate portion of the walking beam, a pitman having one end eccentrically pivotedto the driving element and its other end pivotally connected to the intermediate portion of the walking beam for rocking said beam upon its fulcrum and thereby reciprocating the plunger, and a radius rod having one end pivoted to swing about a fixed axis in the vertical plane of and below the axis of the driving element and its other end pivotally connected to the walking beam between the fulcrum of said beam and the pivotal connection of the pitman with the beam.
