' Application fi1d. July 12,
Our invention relates to power transmission and consists in an encased unit constituting and including within itself both the reduction gear and the power-transmitting connections,- by which the high-speed rota tion of a prime mover is converted into the low-speed reciprocation of the stem of a pump piston or other engine part. The encased unit may be mounted integrally upon and constitute one piece with the frame of the pump. The benefits of the invention include simplicity of structure, economy of space, rigidity, superior lubrication, protection of parts, cleanliness, all combined with eliiciency. I
An embodiment of our invention is shown in' the accompanying crawings. Fig. I is a view in vertical, medial, and longitudinal section of the unit in which our invention is found, combined with a prime mover in the form of an electric motor and with an engine part which in' this case is a pump cylinder. l ig. H is a view in vertical and transverse section, on the plane indicated at ILJT, Fig. I. Fig. III is a view in hori zontal section, on the broken line TIL-III, T. Fig. TV is a vertical section, on the plane IV -1V, Fig. III.
The casing is made up of and constituted by two parts 1 and 2, forming a substantially cubical box with a cover. The body of this box-like casing is constructed integrally with or mounted integrally upon the frame of the machine. In this case the body of the casing is shown to be formed in a single casting with the head of the pump cylinder The pump cylinder 3 extends, when the parts are assembled, horizontally. The body and the cover of the box-like casing close in substantially fluid-tight e11- gagement with one another, and upon a crank shaft 4 to which the meeting faces of the casing parts are shaped and for which these meeting faces carry bearings. When the parts are assembled the crank shaft 4 extends horizontally, in common plane with the axis of cylinder 3, and perpendicularly to the axis of cylinder 3. The stem 9 of the piston within cylinder 3 extends through an orifice formed by and between the meeting edges of the body and cover of the casing, and thus a guide and bearing for the piston stein are provided.
lVit-hin the casing are guides conveniently in the form of rods 5 and 6 mounted one in the body the other in the cover of the casing,
1926. semi No. 121,762.
and, when the parts are assembled extending horizontally, parallel one with another and aligned one above the other in vertical plane, and in parallelisn'i' with and in common vertical plane with the axis of cylinder 3; In guides such as the rods 5 and 6 afford moves a scotch yoke, consisting of the horizontally reciprocating block? provided with a slideway in which a block 8 reciprocates vertically; Block 7 is rigidly connected to the stem 9 of the piston of the pump cylinder 3 and block 8 is pivotally united with the crank 10 with which the crank shaft i is provided. By such means manifestly shaft rotation effects reciprocation of the piston within the pump cylinder.
The crank shaft carries also a worm wheel 11. Suitably ournalledin the cover 2 of the casing, is a shaft 12 which when the parts are assembled extends horizontally, in parallelism, with guiderods 5 and 6 and with the axis of pump cylinder 3, and perpendicularly to the ve'rticalplane in which lies the axis of crankshaft 4. The shaft 12 carries a worm 13 which in the assembly engages the worm wheel 11 upon the crank shaft; The shaft 12 is adapted to be driven by a prime mover, and is here shown to be coupled at 14 to, and to form a prolongation of the driven shaft of an electric motor 15.
Operation is obvious. The motor, or equivalent prime mover drives shaft 12. Shaft rotation at relatively high speed is through the reduction gear shown effective to drive powerfully and at low speed crank shaft at, and rotation of crank shaft 4 effects through the connection shown pump operation.
Then the assembly has been completed and it becomes necessary for any reason to have access to the interior of the casing, all that is necessary is to release the coupling 14. The cover 2 may then be removed from the body 1 of the casing, carrying with it and secure in position upon it the upper guide rod 6 and the shaft 12. These last named parts are then freely accessible. At the same time, the removal of the cover renders freely accessible the crank shaft f with its worm wheel, the reciprocable rod 9, and the connections between rod and shaft. Also the casing is open for the removal and renewal of lubricant.
The novel features are simplicity, compactness, enclosure in a common casing of both reduction gear and driving connections;
the mounting of the whole unitarily upon the frame of the machine, whereby alignment is fundamentally established, and permanence of adjustment and rigidity secured; closure against wasting of lubrication, fowling of gears, and splashing of lubricant, and against accidental contact with oil-covered parts; the maintenance of a bath of lubricant within the casing, in which single bath both the reduction gear and the driving connections find common automatic lubrication. Shafts 9 and 12 extend in parallelism and here is economy of floor space. Motor 15 may be set in axial, parallelism with and closely adjacent to thepump cylinder, spaced from it by only the small interval necessary for the setting ofthe compact casing 1, 2.
We claim as our invention:
1. In power-transmitting apparatus the combination of a casing consisting of body and cover, a shaft extending within the casing and journalled between such body and cover, a reciprocable rod extending through an orifice in the casing wall formed by and between the meeting edges of body and cover, the said shaft being provided within the casing with a crank and the said rod being operatively connected within said casing with such crank, and means for rotating said shaft.
2. In power-transmitting apparatus the combination of a casing consisting of body and cover, a shaft extending within the casing and journalled between such body and cover and provided within the casing with a crank, a pair of rods borne one by the body of the casing and one by the cover and when the parts are assembled extending in parallelism one with another and in a common plane to which said shaft lies perpendicularly and on opposite sides of said shaft, a scotch yokeborne by said rods and connected to the crank with which said shaft is equipped, and a reciprocable rod extending through the walls of said casing and engaging said scotch yoke.
3. In power transmit-ting apparatus the combination of a casing consisting of a body and a cover, a crank shaft extending within the casing and journalled between the meeting edges of body and cover, a reciprocable rod extending through an orifice in the casing wall formed by and between the meeting edges of body and cover, said rod extending when the parts are assembled perpendicular to the crank shaft, two rods borne one by the body of said casing and the other by the cover and when the parts are assembled extending on opposite sides of said crank shaft and parallel one with another and with said reciprocable rod, av scotch yoke borne by and reciprocable upon said rods and operatively connected both to said crank shaft and to said reciprocable rod, a rotatable shaft journalled in the cover of said casing, and driving connection between the last-named shaft and said crank shaft and arranged within said casing.
