MECHANICAL MOVEMENT.
Specification of Letters Patent.
Patented 1166.9, 1919.
Application filed December 26, 1918. Serial No. 268.219.
To all whom it may concern:
Be it known that I, HUGH D. McKnLvnY, a citizen of the United States, residing at Salida, in the county of Chaifee and State of Colorado, have invented certain new and useful Improvements in Mechanical Movements, of which the following is a specification.
This invention relates to mechanical movements and more particularly to movements of the (.llfllflClUl shown and described in my application for Patent No. 250.579. filed August 9, 1918.
In this application. a construction is dis closed which operates a pump by the combined actions of gravitation and centrifugal force upon a rotating weight, and it is the primary object of the present invention to increase the efficiency of the movement by a novel and more simple arrangement of its cooperative parts.
With this and other objects in view. all of which will fully appear in the course of the following description, my invention consists in the constructions and combinations of elements shown in their preferred form in the accompanying drawings in which like characters of reference designate corresponding parts throughout the several views and in which- Figure 1 represents a side elevation of a movement containing the improvements;
Fig. 2, a section on the line 22, Fig. 1;
Fig. 3, a section taken on the line 33, Fig. 2;
Fig. 4:, a side elevation of a modified form of the invention;
Fig. 5, a section taken on the line 5-5, Fi 4, and
Fig. 6, a side elevation of another modifi cation of the improved movement.
Referring first to Figs. 1 to 3 of the drawings, the reference numerals 2 designate a pair of standards provided with vertically extending slide-ways 3 in which two boxes 4 have a reciprocating movement.
A shaft 5 rotatalbl supported in the boxes carries a pulley 6 w ich by means'of a belt 7 is operatively connected with a policy 8 on the rotating element of a motor 9.
The motor is preferably disposed so that its axis of rotation is approximately in a horizontal plane with. the axis of the shaft- 5 thereby permitting of the reciprocating movement of the boxes without disturbing the cooperative arrangement of the pulley and the belt, it being understood that the latter has the usual slack to allow for a limited longitudinal expansion.
Springs 10 and 10 placed in theslideways, engage the boxes to cushion their up and downward movements, and set-screws 12 at the upper ends of the standards engage bearing plates 13 for the purpose of regulating the presure exeiied by the upper springs.
The shaft equipped with'two laterally extending spokes or arms 14 which at their outer ends valry weights l5 prcferablv composed of a number of sections secured be tween nuts We?fin The shaft ex ds freely through the head of a rod 17 which connects with a piston 18 slidingly fitted in the stationary cylinder 19 of a double action pump of ordinary construction.
The portion of the shaft upon which the arms are mounted, and the pump may be ineloscd in,an air-tight cylindrical casing 20 which if so desired can be connected with an exhaust pump for the production of a partial vacuum in its interior to reduce the resistance to the movement of the rotating weights and thereby increase the efiiciene of the mechanism. I
In order to permit of an up and down movement of the shaft, the casing has in its opposite side walls vertical slots 21 through which the shaft freely extends. The slots are closed against the passage of air by covers 22 which engage the Walls of the easing at opposite sides and which have open= in s in which the shaft is rotatably fitted.-
o insure against the leakage of air around the shaft through these openings, the latter are recessed and provided with paokings which engage the surface of the shaft as shown in Fig. 2 of the drawings.
In the operation of the mechanism a rotary movement is imparted to the shaft by the action of the motor with which it is connected. During the upward movement of the arms 14 the action of centrifugal 'force upon the weights at their ends will cause the boxes in which the shafts are supported to move upwardly in their respec- 1 tive slideways against'the pressure of the springs 10. a 1 a l During the subsequent downward move ment of the arms the centrifugalforce augmented by the gravitation of the Weights, will compel the boxes to move in the opposite direction, and a vertical reciprocating n'iovement is thus imparted to the rotating shaft and the therewith connected piston ol the pump.
The dates covering the slots of the rasing move with the shaft and by connecting an outlet 22-} of the casing with an exhaust pump. a partial vacuum may be produced to reduce the resistance to the movement of the weights and thereby increase the eili ciency of the mechanism.
The casing also serves to protect persons in the vicinity of the mechanism aga nst in jury by contact with the rotating weights.
By increasing or diminishing the number of sections of which the weights are com-- posed and varying the pressure of the springs 10 by adjustment of the set-screws, the extent of the reciprocating movement 01 the. boxes may be regulated at will.
It will be understood that although the movement has been shown. in the drawings in connection with a pump, it may be cll'ec tively employed to impart motion to other contrivances which for their operation depend on the impellent movement of a reciprocating element.
In the construction shown in Figs. 4 and 5, the shaft extends freely through the slideways of the standards and rests in boxes 24 at the ends of the piston rods 25 of two single-action pumps 26 the cylinders of which are mounted between the diverging legs of the standards.
In the construction shown in the drawings, but one weight 28 is provided and it is formed on the rim of a wheel 29 which is connected with a hub on the shaft through the medium of a number of light spokes 30. it being the purpose of the wheel thus formed, to protect operatives and bystanders against injury, in the place of the air-tight casing of thefirst-described construction.
'Iae modification shown in Fig. 6 of the drawings. illustrates the. feasibility of roduci'ng by rotation of a weighted sha t, a reciprocating motion in planes outside the vertical.
A pair of. standards 31 have in this construction circularly bored bearings 34 for correspondingly formed boxes 32 which are secured: in their adjusted positions by setscrews 33.
The boxes have di-ametrical slots 35 which perform the functions of the slide-ways of the standards of the first-described con struction, in directing the reciprocating movement of boxes 24 in connection with a piston: or pistons of one or more pumps of 0251 suitable construction.
If the cylinder of the pump stands vorti cally as in the construction shown in the drawings, the boxes are formed at the ends of connecting-rods which are pivotally connected with the piston-rods as at 36. The position of the driven element with relation to the moven'ient is, however, arbitrary, and the movement may be employed to actuate reciprocating pistons, tables and other devices which operate in planes outside the perpendicular.
By adjusting the boxes 32 in their respec tive bearings the movement shown in Fig. 6, may be readily adapted for use in imparting a movement to apparatus of differing types irrespective of their position and construe lion or the plane in which they operate.
The boxes ll of the last-described construction support. as before, a rotary shui'l i which carries one or more weights 1.) at a distance from its center of rotation, and springs 10 and J0" are provided to cushion llit l'llfllllffl'litlllgj' motion of the boXcs.
l'laving' thus explained the nua-hunical movement in the best forms at present known to me. it will be understood that modifications other than those herein shown and described may be resorted to within the spirit of my invention as defined in the hereunto appended claims.
The number of arms or wheels for the support of the weights may be varied from one to as many as is desirable. Contrivances other than pumps may be placed in operative connection with the shaft as stated herein-- above. and the number of these contrivances that can be operated synchronously by the reciprocation of one and the same shaft is limited only by the capacity of the movement.
In the form shown in Figs. 4 and 5, a hand-crank 37 is provided in the place of the pulley 6 of the construction shown in Fig. 2, to impart a rotary motion to the shaft, it being understood that if a crank is used the operator is obliged to follow the reciprocating movement of the shaft and therefore move the hands which hold the handle of the crank, in a substantially elliptical path.
The drivin power of the movement is in each form 0 my invention, produced by a lateral reciprocating movement created by the actions of centrifugal and gravitative forces upon a weight carried by a rotating shaft at a distance from its center of rotation. The power required to rotate the weighted shaft is inversely proportionate to its velocity and the power produced by its rotation is in direct proportion to the same, and inasmuch as the rotary movement of the shaftis independent of the resistance offered by the load, excepting its frictional contact with the boxes in which it is supported, the energy required for the operation of the movement at its normal velocity, is little in comparison with the driving power it produces.
