ALFRED CARLSON, F KLAMATH FALLS, OREGON.
POWER-TRANSMITTING DEVICE.
Application filed March 3, 1922. Serial No. 540,795.
To all whom it may concern:
Be it known that I, ALFRED CAaLsoN, a citizen of the United States, residing at Klamath Falls, in the county of Klamatn and State'of Oregon, have invented certain new and useful Improvements in Power- Transmitting Devices, of which the following is a specification.
The present invention relates to certain new and useful improvements in gearing of that type which is utilized for converting a rotary motion into a reciprocating motion, and among the objects of the invention is to provide gearing of this character which embodies novel features of construction whereby the desired result can be attained without the necessity of using a pitman or an analogous member.
Further objects of the invention are to provide a gear device of this character which is comparatively simple and ineX- pensive in its construction, which comprises strong and durable parts, and which will transmit the motion in an efiective manner and with a minimum loss by friction.
With the above and other objects in view, the invention consists in certain combinations and arrangements of the parts, as will more fully appear as the description proceeds, the novel features thereof being p0int-.
ed out in the appending claims.
.For a full understanding of the invention reference is to be had to the following description and accompanying drawings, in which:
Figure 1 is a vertical sectional view through an air compressor which is equipped to be driven by gearing construct ed in accordance with the present invention.
Figure 2 is a sectional view on the line 22 of Figure 1 looking in the direction of the arrows.
Figure 3 is a detail perspective view 01 the planetary gear element.
Figure 4 is a detail sectional view showing a modified form of gearing for establishing a driving connection between the drive wheel and the inclined shaft.
Figure 5 is an interior view of the hubcap which is applied to the drive wheel in themodifications illustrated by Figure 4.
Corresponding and like parts are referred to in the following description and indicated on all of the views of the drawings by like reference characters.
Referring to Figures 1 and 2 of the drawings, which illustrate one of many possible embodiments of the invention, the numeral 1 designates a gear casing which is supported upon a base 2 and arranged below an air compressor A. The gear casing 1 is pro vided with a laterally projecting tubular bearing 3 within which a core member or sleeve 4 is rotatably mounted. A shaft 5 extends longitudinally through the member 4, being arranged at an inclination to the axis thereof, and being suitably journalled within a bushing 6. The outer endof the shaft 5 is concentric with the sleeve 4, while the inner end thereof is off-set from the center of the sleeve and arranged eccentrically with respect thereto. A pinion 7 is keyed upon or otherwise fixedly applied to the outer end of the drive shaft 5 and this pinion. meshes with the interior teeth 8 of a hollow hub cap 9 which is applied to the drive wheel 10. The hub of the drive wheel is journalled upon the reduced outer end 3 of the tubular bearing 3, and power may be applied to the drive wheel in any suitable manner, as by means of the usual endless drive belt. The interior of the hub of the drive wheel 10 and the reduced end 3 of the tubular bearing are provided with corresponding race ways to receive the antifriction balls 11, said balls being adapted tobeplaced in position or removed therefrom through an opening which is normally closed by the plug 12. The pinion 7 is ar ranged in a plane which is at a slight inclination to the plane of the drive wheel and hub cap, although the teeth of the pinion engage or interlock with the interior teeth 8 of the hub cap so that the drive shaft 5 is rotated with the drive wheel, the intermeshing teeth of the pinion and hub cap sliding back and forth upon each other longitudinally as the parts rotate.
The opposite end of the drive shaft 5 is provided with a pinion 13 which meshes with a planetary gear 14, said gear 14 being journalled upon a crank pin 15 upon the flanged inner end of the core member or sleeve 4. The planetary gear 14 also meshes with the interior teeth of a gear ring 16 which is fixedly mounted within the casing 1. The diameter of the gear ring 16 is approximately twice the diameter of the planetary gear 14, so that the planetary gear 14 will make two complete revolutions each time that it. travels once around the interior of the gear ring 16. The relation between the pinion 13 and the planetary gear 14 is such that the point of engagement between. the two elements is at the astis ot' the sleeve member 4. and interior gear ring 16. The inner end of the core member or sleeve 4- which is provided with the crank pin 15 is enlarged or flanged, as indicated at 4 and is loosely engaged by a sectional retaining ring 17 to hold the sleeve member in position and prevent longitudinal movement thereof. The pinion 13 is provided with a suitable bushing 18 to receive the cranlcpin 15.
The planetary gear 14, shown in detail by Figure is provided with an outwardly projecting wrist pin 19 which engages the lower end of the piston rod of the air compressor A. The axis of the wrist pin is arranged at the effective periphery of the planetary gear 141 and the parts are assembled in such amanner, as indicated by Fig ure 2 of the drawings, that when the axis of the planetary gear 14 is on the horizontal diameter of the interior p ear ring 16. the wrist pin is at the center of the interior gear ring. The relation between the plan etary ,26511" 14: and the fixed gear ring 16 is such as the planetary gear 14 travels around the interior periphery of the gear ring 16 the wrist pin 19 moves up and down in a rectilinear path on the vertical diameter 01" the fixed gear ring 16. In other words, the lateral movement. of the planetary gear 14: as it moves around the interior of the gear member 16 compensates for the lateral movements of the wrist pin 19 which would otherwise be incident to the rotation of the planetary gear and permit the wrist pin to reciprocate in an up and down vertical path without any lateral movement. The lateral movement of the wrist pin is rendered unnecessary owing to the planetary move-- ment of the gear 14 and the wrist pin has a plain rectilinear or reciprocating movement. The interior of the gear case 1 may receive lubricant and the various gear members and the core member or sleeve 4: are provided with passages 21 through which the lubricant is caused to travel when the rearing is in operation. All of the moving parts are thus properly lubricated so that the mechanism operates with a minimum amount of friction and without any unnecessary wear and tear upon the parts.
The air compressor A may be of any conentional construction and is merelvillustrated for the purpose of showing; one war of utilizinir the earing of the invention. The upper end of the piston rod 20 is connected with a piston 22 which reciprocates within a cylinder 2%. The compressor is of the double acting type. and both ends thereof are provided with inlet valves 25 and outlet valves 26. These are of the well known construction and no claim;- to
novelty is based thereon. It will be obvious that in the operation of the compressor air is alternately drawn in to the opposite ends of the elyinder through the inlet valves 25 and discharged through the outlet valves 26 into a passage or chamber 27 which is in communication with a suitable compressed air container. The piston rod 20 has a direct up and down movement and a rotary motion of the drive wheel and drive shaft transferred thereto without the use of any pitman or similar members. A direct drive obtained upon the piston rod at all times and the rotary movement of the drive wheel is converted into a reciprocating rectilinear movement in a direct and positive manner and with a minimum loss of power.
Figures 4 and 5 oi the drawings illustrate a slight modification in which the pinion '7 at the outer end of the drive shaft is provided with laterally projecting teeth instead of with peripherically projecting teeth as in the previous instance. The hub cap 9, shown in detail by Figure 5 is correspondingly modified. although the teeth of the two members lDi'QllOCl with each other exactly in the previous form of the invention with the result that the drive shatt 5 rotates with the drive wheel. although the teeth of ihe pinion 7 and hub cap 9 slide in and out on each other as the members are rotated. These members provide what is in effect a loose connection between the drive. wheel and the drive sh aft whereby the drive shaft is rotatable with the drive wheel although it is disposed in an angular relation to the axis of the drive wheel.
The inner end of the hub of the wheel 10 is formed with a short extension or flange 10 which fits within a recessed or undercut portion 10" in the bearing sleeve. The bottom of the undercut portion communicates with one of the oil passages 21. and it will be obvious that with this construction a lulnicant will circulate freely through the hub and backinto the casing so that all of the parts will be properly lubricated when the device is in operation.
