MECHANICAL MOVEMENT.

Specification of Letters Patent.

Patented Mar. 18, 1 91 3.

Application filed December 22, 1910. Serial No. 598,685.

To all whom t may concern:

Be it known that I, WILLIAM S.-HARMON, a citizen of the United States, and a resident of Arleta, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Mechanical Movements, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to novel improve ments in mechanical movements.

The primary 'object of my invention is to provide a simply constructed and readily operated mechanism for utilizing the dynamics of a rapidly rotating and moving body.

Another object is to provide a means for converting the tilting motion of a swivelly held member into a vertical reciprocating motion.

A still further object is to provide a comparatively inexpensive mechanism for o-perating pump plunger-s and similar devices' actuated by means of rock shafts.

A. further object is to secure a flywheel to a shaft capable of rotation at great speed, said shaft rotating upon two superposed bearings of a tiltably held member, the wheel traveling in a circle, the movement of said'member being utilized to actuate a rock shaft. l

lll/lith these and other objects in view, the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described and par-I ticularly pointed out in the appended claims, it being understood that changes in the specilic structure shown and describedI may be made within the scope of the claims without department from the spirit of the invention. l

In the drawings formin a part of Athis specification, and inwhich. ike numerals of reference indicate similar parts in the sev-Y eral views:-Figure 1 shows an elevational view with portions broken away of a mechanisin embodying my invention. Fig. 2 shows Va top View of my mechanical movement. Fig. 3 discloses a partly lsectional detail of the supporting gudgeon. Fig. 4 isp-.an elevational detail of the lower or end roller disclosing the arrangement of the ball bearing. Fig. 5 shows an enlargeddetai'l of the driving andy idler gears'. Fig. 6 shows a modification` of the driving shaftsupport,

and Fig. 7 a detail of the rock shaft.

In carrying out the object of my inventionI employ a base 1, having the securing feet 3, and the centrally disposed upstanding rack teeth 7 Centrally this base has a hub 2, having a threaded opening 2', within which there is adjustably held the socket gudgeon 3. Held within the socket of the gudgeon 3 is the sphere 5 of the bolt 4, this sphere being held in position by means ot' the cap 10', which has an opening permitting the end of the boltA 4 to be carried in a circular path. Held to the cap 10 is the plate 6 having the depending circularly disposed rack teeth 8 arranged for co-action with the rack teeth y7. This plate. 6 has a centrally disclosed hemispherieal socket arranged to receive the cap 10 as clearly dis posed in lFig. 3., the nut 10 threading upon the bolt 4. to hold the plate Gto the cap 10. Secured t0 this plate 6 which is swiveled to the .gudgeon 3 are the outwardly bowed brackets 12 which give firm support to the annulus 13, havin@r the two parallel circular splayed bearing edges, a and I1.

As disclosed in Fig. 1 there is an access space between the plate (i and the annulus 13 andheld within this access space is the end ot' the driven shaft 9, to which is adjustablly secured the fly wheel 2i. This fly wheel is fixed to the shaft 9 in a manner permitting the same being carried away from or toward the projecting end of the shaft 9.

In Fig. 1 the iy wheel 24 is .shown at the end of the shaftl 9. In Fig. 6 however where the shaft is shown as Very much longer than in Fig. 1, the fly wheel 24 is shown at a point intermediate of the ends of the shaft. Secured to the end of the shaft 9, opposite the fiy wheel 2i is the conical roller 15 arranged for (3o-action with the lower splayed bearing a.. In Fig. 1

this bearing 'a is shown as inelining toward the centeroffthe annulus, while. in Fig. 4 the lower bearing ainc'lines away from the lcenter of the' annulus. Held adjacent to the roller 15 is a 'cap 15', having a ball race within which are held a plurality of balls 47 held in position by means of the stay plate 49. The balls 47' are arranged to rotate against an outer peripheral surface of the annulus 13 and assist intaking up part of the` end thrustof the shaft 9 when in operation. A cap 15 is held in position by means of the nut 16. Secured near the opposite end of the shaft 9 and arranged ,for

co-action with the upper circular splaycd As shown in Fig. 1 the roller 14 engages.

the upper bearing and the roller 15 the lower bearing, the shaft being held in a slightly inclined position, the highest end of the shaft being at the end which carried the fly wheel. It is of course understood that the angle of the shaft 9 may be in* creased in increasing the diameter of the intermediately disposed roller 14.

The instrumentalities described form a balanced member which is permitted a tilting movement within certain limits in being swivelly connected to the adjustably secured gudgeon 3. The tilting movement` may be increased or decreased by raising or lowering the gudgeon 3.

Depending from the bearing 1 are the oppositely disposed bearing ears 60, within which bearings is held the rock shaft 21, the

shaft having therockarms 22, each carrying apin 23, giving pivotal support to a connecting link 20, two such links being used and these links in turn are secured to'the pins 17 projecting from the plate 6, as clearly disclosed in Fig. 1. Held immediately above the point marking the center of the base 1, is a driving shaft 31, this shaft carrying at its lower end a driving pinion 26. This pinion 26 meshes with the pinion 25 secured to the shaft 9. On rotating the shaft 31 a rotary movement is vimparted to the shaft 9, which shaft at the same time is swun in a circle about the driving pinion 26. s the vshaft 9 revolves it travels over the twoparallel circular bearings, a and b, and in doing so tilts the annulus in its progressive movement. This tilting movement of the annulus and the connected plate 6 is converted into a reciprocating movement, and imparted to the rock shaft 21 by means of the members 20 and 22. As there is a tendency of the fly wheel 24 to travel away from the center marked by the-gear 26, I prefer lusing an idler gear 25 shown in Fig. 4 which is held in mesh with the driving pinion 26 between the collars 45 and 46. In this way the idler 25 takes up'part of the end thrust of the bearing 9.

.In Fig. 1 the driving shaft 31 is given support within the standard 29 above, while below the shaft 31 is held within the bear ings 27 supported by means of the brace arms 28,. In Fig. 6 I show a modification in which the driving shaft .31 is adjustably held in that the shaft 31. rotateswithinA the bearings 40 and 42, held by the bracket' 40 which is secured to a suitable support overhead. The collars 45 and 44 control the position of the shaft 31 which above Iis provided with the driving pulley 43. This pulley Igives support to a suitable driving belt. Fig. 1 I have shown a grooved pulley 32 engaged by the driving belt 33.

In Fig. 7 I have shown a detail of the rock shaft 21 disclosing the pump arms 23 to which thepump plungers are secured.

The shaft'9 is automatically and mechani cally balanced and held in a horizontal or other desired plane. In order to insure the pins 17 being held immediately above and in alinement with the'rock shaft 21, I have employed the intermeshing rack teeth 7 and 8. While the annulus 13 and plate are shown as two distinct and separate parts connected by means of the brackets 12,it should be understood that the annulus and plate could be cast in one by providing a groove within which 'the projecting end of the shaft 9 could travel. After the shaft 9 has been started and set in motion the same can be given a high rate of speed with but a slight expenditure of driving power resulting in a rapid and powerful stroke being imparted to the pump arms 23.

From the foregoing it will be seen that broadly my invention comprises an equilibrated member having two parallel circular bearings, a revolving shaft with a ily wheel supported and 'guided by said bearings, means to swing said shaft about a'xed center located intermedi-ate of its ends, and mechanisms connecting said equilibrated member to a rock shaft.

A device constructed according to my invention is comparatively inexpensive and the working elements are all readily accessible and adjustable.

Having thus described my said invention what I claim as new, and desire to secure by United States Letters Patent is 1. In combination, a ysupport-ing base prov-ided with circularly disposed rack teeth, a gudgeon adjustablysecured to said base, and an equilibrated member adjustably secured to said gudgeon having rack teeth for coaction with said base rack teeth.
