EDWIN EARL ARNEY AND DAVID ARNEY, OF BARKER; SOUTH DAKOTA.
MECHANICAL MOVEMENT.
Specification of Letters Patent.
Patented Oct. 2, 1917.
To all whom it may concern Be it known that we, EDwIN E. Annnr and DAVID ARNEY, citizens of the United States of America, residing at Parker, in the countyof Turner and State of So. Dakota, have invented certain new and useful Improvements in Mechanical Movements, of which the following is a specification.
The present invention relates to improvements in mechanical movements, and is designed to provide a power t'ansmission apparatus whereby the rotary movement of a prime motor may be converted into a reciprocal movement for imparting power to, or operating certain machines, as pumps, washing-machines, churns, sewing machines, and analogous light duty machines. The )rime object of the invention is the pro vision of a device which is comparatively simple in construction and operation, which is inexpensive of production and maintenance, but withal both durable and efficient in performing the functions for which it is intended.
The invention consists in certain novel combinations and arrangements of parts as will hereinafter be more fully pointed out and claimed.
In the accompanying drawings we have illustrated one complete example of the physical embodiment of our invention constructed according to the best mode we have so far devised for the practical application of the principles of our invention.
Figure 1 is a front elevation of the physical embodiment of our invention, applied for use in connection with a standard pump for elevating water from a well.
Fig. 2 is a sectional view of the housing of the device of Fi 1 disclosing in full lines an edge view of the operating parts of our invention.
Fig. 3 is a plan view showing in front elevation the invention.
Fig. i is a detail view of the oscillatable arm or pendulum, showing a modified form of flexibly attached weight at the end of a the arm.
Fig. 5 is a detail view of the crank mechanism and connections.
In the accompanying drawings we have illustrated a pump 1 as the machine or device to which the invention is applied, but it will be understood that we do not limit ourselves to this use of the invention alone, as the invention is equally applicable to other similar machines. The reciprocable pump rod 2 of the pump is the element to which our invention is directly connected for the purpose of imparting motion thereto, and the pump rod rcciprocates vertically as usual.
By means of the braces 3, 3, attached to the pump and supported from a platform, a housing i is supported in close relation to the pump in order to inclose and protect the working parts of our invention.
Within the housing, a prime motor 5 is incased, and this motor may be a spring or it may be other suitable driving power having the train of gears (3 operated therefrom which train includes the (lrivin gear 7 and pinion 8, the latter on the (riving shaft 9 which forms a crank shaft for the crank 10 which revolves about the shaft. By means of the connecting link 11 the crank is connected to a rack lever 12, pivoted at 13 in a partition or frame 14L of the housing and formed with the segmental rack 15 which engages the rack wheel 16, also jonrnaled in the frame 1a, and through the medium of the link, rack lever and pinion or rack wheel 16, the rock lever 17 is rocked or swung about the shaft 18 as a center, the shaft being journaled in the frame 14.
Through the medium of the above described mechanism the long oscillatable lever arm 19 caused to swing on its pivot 20 with a motion similar to that of a pendulum and the lever arm is connected to the rock lever through the slot 21 and a head :22, the slot being provided to allow for the movement of the lever arm and the rock lever on their respective centers, and the movements of the lever and arm being designated by the dotted lines in Fig. 3.
The oscillatable arm is supported on its pivot 20 in the housing, and at its upper end, or short arm end, the arm is provided with a segmental gear 23 meshing with the rack wheel or gear 24!.- journaled on stud shaft 25 in the upper end of the housing. At its lower end the oscillatable arm is provided with a weight 26 having at 27 a flexible connection with the end of the arm so that when the arm oscillates or swings as indicated by the dotted lines, it will be seen that the effect of the loosely connected weight is to continue the impetus of the outstroke, and then after reverse movement, by its added weight, to aid in the initial movement of the instroke of the long arm of the oscillatable lever arm. This oscillatable action of the long arm through the segmental rack and rack gear, causes the rock shaft of the gear 24; to rock in its bearings, and a rocker arm 28 fixed on this rock shaft is thus causedto swing as indicated in dotted lines Fig. 3, backward and forward through an'arc of approximately 180 degrees, and through the connection of the link 29, and pitman 30 which reciprocates in brackets 31, the pump'rod is reciprocated as will be readily understood. In Fig. & the oscillatable lever arm is pro-- vided with a modified form of flexible con-' nection between the arm and the Weight, the
similar to the function of a fly wheel on a machine, or engine.
F mm the above descrlption, taken in connectlon wlth my drawings 1t 18 ev1dent that the rotary movement of the prime motor,
is, with facility, converted through the medium of the crank, the rack levers, and
segmental gear and rocking gears and conadapted to impart rotary motion, of a housing, a crank shaft and crank supported in the housing, a rack wheel and'rack lever and a link connecting the crank andlever, an oscillatable lever arm pivoted in the housing, a rock lever actuated by said rack wheel and adapted to oscillate said arm, and a flexibly connected weight depending from the arm, a segmental gearat the upper end of th arm, a rack gear actuated by said segmental gear, a rocker arm actuated by the rack gear, and alink and pitman connection for said rocker arm for the purpose de scribed.
In testimony whereof we affix our signa:
tures.
