CHARLESE. GODLOVE AND JAMES L. VAN NOBT, OF ST. LOUIS, MISSOURI; SAID VAN 1\TORT ASSIGNOR, BY MESNE ASSIGNMENTS, TO SAID CHARLES E. GODLOVE, OF ST.

' LOUIS, MISSOURI.

United States, residing at the city of St.

Louis, State of Missouri, have invented certam new and useful Improvements in Motors,

- of which the following is a specification,

reference being had therein to the accompanying drawings.

This invention consists in improvements in motors of the hydrocarbon variety, the main features of the invention residing in the fact that, in lieu of the ordinary rotation of the crank shaft the Cylinders revolve around a stationary crank shaft, and the means for producing such revolution. These and other features of invention will be pointed out in the claims.

In the drawings, like numbers of reference denote like parts wherever they occur, and Figure l is an end elevation; F ig. 2 is a top plan view; Fig. 3'is a sectional view on the line 33, Fig. 2; Fig; 4 is a sectional view on the line 44, Fig. 2; Fig. 5 is a transverse sectional View on line 5-5, Fig. 1 Fig. 6 is a sectional view on line 6-6, Fig. 5; Fig. 7 is a face View of the diaphragm pump; Fig. 8 is a face view of thecam casing with a portion broken away; and Fig. 9 is a side view of the cams.

The casing l is rotatably mounted on ballbearing' collars 2' on the stationary hollow crank-shaft 3. One end of said crank-shaft is supported in a sleeve or bracket 4 and held stationary therein by a key 5, or other suitable means.- The lock-nut 6, provided with packing ring fits closely around said crank shaft, and, in threaded engagement with casing 1, holds ball-bearing collar 2 in place. At the other end of said crank-shaft, the diaphragm pump 8 is fastened thereto by pins 9, which are inserted into the perforations 10 of the crank-shaft 3, and extend into notches 11 in the neck portion 12 of said diaphragm pump, and prevents same from turning with casing I. Said neck portion 12 of diaphragm pump 8 is provided with aperture 13, one end of which terminates in the hollow compartment 14 of the crank-shaft 3,'and the other end'of said aperture is adapted to form a seat 15 which receives the ball 16, and forms therewith checkvalvo 17. Said ball 16 is normally held off said seat 15 by the pressure of the fuel fluid in the hollow crankshaft, and is Specification of Letters Patent.

seated under the influence of spring 18 when diaphragm 19 is depressed.

The body portion 20 of the diaphragm pump 8 is provided with shoulder2l, which lits closely against the end of crank-shaft 3 adjacent thereto. The outlet passage 22 in diaphragm pump 8 extends from the circularly beveled face 23, and terminates in the diaphragm chamber 24 underneath diaphragm 19, which is held in place by the hollow lock-nut 25.

The driving shaft 26 is journaled in a sleeve 27, or other suitable bearing, and is provided with the casing or housing 28, preferably integral therewith, which is fastened to casing 1 by bolts 29, and rotates therewith. Said housing 28 is provided internally with a circularly beveled side 30, which tightly encircles the beveled face 23 of diaphragm pump 8, and rotates thereon. Spring 31 holds the beveled face 23 closely against the beveled side 30, and prevents the leakage of the fuel liquid between the contacting surfaces 23 and 30. Said housing 28 is provided with passages 32 which terminate at one end in the beveled side and register with the outlet 22 of the diaphragm pump 8 when said housing is revolved. The other end of each of said passages 32 terminates in an aperture 33, each of which receives a pipe 34. The lever 35 is pivoted at one end in the slotted compartment 36 of the driving shaft 26 by pin 37, and is provided with a projection 38. The other end of said lever 35 is preferably rounded and depressed during the rotation of the driving shaft by the stationary cams 39, which causes the depression of the diaphragm 19 by the projection 38 on said lever. Each of said cams 39 is preferably formed integrally on one end of a rod, 40, which is threaded at the other end to receive a nut 41. Said rod 40 passes through a washer 42 and a sleeve 43. which is in threaded engagement with the disk 44. The sleeves 43 allow the separate adjustment of thecams 39. The cam disk 44, which is provided with acking rings 45, tightly encircles the driving shaft 26, and is closely encircled by the housing 28, but does not rotate therewith. Said cam disk 44 is held in position by a rod 46, one end of which runs to a suitable adjusting device (not shown in the drawings),

and the other end terminates in a fork 47.

Each of the prongs 48 of said fork is atin the exposed end of portionun the crank the hollow portions in the Y the outer surface of said'cap,

tached to the cam disk 44 by set-screws 49 in the lugs 50 on said disk, or by other convenient means. Said rod 46 permits of the longitudinal adjustment of thecam disk 44 1 and, consequently, the adjustment. of: the eams 39 in unison therewith.

Theplug 51 said crank-shaft is provided with an aperture 52, which receives-the supply pipe 53. Said pipe 53 conveys the fuel liquid from any suitable reservoir 54, which is located above the crank-shaft," and forces the liquid by gravity into the hollow compartment 14 of the crank-shaft 3, and maintains a pressure on the liquid in said hollow compartment. As the passage through shaft 3 would be most conveniently formed by drilling; the hollow portion in the crank part is sealed at one end by a plate 55, which is preferably brazed'therein, and the other end is tapped to receive the threaded plug 56. The hollow part of crank-shaft?) is connected with straight parts of said crank-shaft by passages 57 and 58. Said plug 56 is provided with an angular passage 59, which registers with said passage 58 and is held firmly in position by a pin 60. I I

The stufiing boxes 61 are fastened td the casing l by bolts 62, and are provided with a by-pass chamber orchambers 63, which extend outwardly from said casing Extendinginwardly into 'the interior of said casing is a projection 64, which is provided with a recess .65. 'Each of said stufling boxes 60 receives a cylinder 66 which is preferably welded thereto. Said cylinder is provided with a cap 67 which is in threaded engagement with said cylinder and formed with perforations 68 extending partly into and in the inner surface of said cap a recess 69 is formed.

An aperture 70 extending through said cap 67 is adapted to receive said pipe 34 and a check valve 71.

burned gases.

, .Said valve 71 is, formed with a ball 72, which normally closes the end of pipe 34 in aperture 7 O by the pressure of spring 73. Said cylinder 66 is provided with a port 74, which permits of the entrance of the fresh air and the exhaustof the The openings 7 5'and 76 concylinder with the by-pass chamber 63, and allow the entrance into, and exhaust from, said by-pass chamber of fresh air. u The piston 77. is provided. with ordinary packing rings 78, and, on the upper surface of said piston, a deflector 79 is provided,

nect the interior of said which enters the recess 69 when the piston Adip Said piston passes to the cylinders the heat of combustion hollow piston rod 81 extends through said piston, and isfastened thereto by. nut 82. through stuffing-box 61, which is provided with split metallic pack ing rings 83, preferably of triangular section. Said packing rings 83, when forced together by nut 84, form an adjustable, as well as an air tight, bearing. The other end of said piston rod is welded or brazed to a Scotch yoke 85, which is slidablyand rotatably mounted on crank-shaft 3 by means of ball-bearing collar 86. The members of each pair of piston rods 81 are fastened diametrically opposite to each other to one of the Scotch yokes 85, and thus balance the motor. The perforations 68 in the cap of the cylinder 67 increase the radiating surface, and, consequently, aid in cooling the cylinder.

The casing 1 is filled with lubricating oil, which preferably contains a quantity of graphite, which prevents the objectionable deposit in the cylinder of carbon from the burning gases. Said lubricant is supplied through an aperture 87 in casing 1. Said aperture 87 registers'with valve 88 in the chamber 63 of sufling box 60. A ball 89 isintegrally formed on the end. of valve stem 90, which operates in an elongated assage 91 in the plug 92. Spring 93 normally keeps said valve 88 closed, said valve being opened by the centrifugal force of the motor, thus allow'ng the cylinder to receive its supply of lubricant proportional to the speed of the motor. The operation of the motor is as follows: In starting the motor, the driving-shaft 26, which may 7 crank-handle,.causes the cylinders to rotate therewith. Therotation of the cylinders re.-

sults in the compression of the fresh air in the head of each of said cylinders during the outward or compression stroke of its piston, whichproduces a temperature about equal to Coincident with the completion of the compression stroke, the passage 32 regi' ters with the outlet passage 22 of thediaphragm pump 8, and thelever 35 registers with a cam 39, which depresses said lever and causes the depression of the diaphragm 19. This depression of the said diaphragm closes the check valve 17 and forces a charge of the liquid fuel (which is preferably gasolene, but heavier h dro-carbon fluids may be successfully used diaphragm chamber 24 through the passages 22 and 32, thence through pipe 34, and sprays the liquid fuel through check valve 71 into the air in the head of the cylinder made hot by compression. The charge of the liquid fuel sprayed into thehead of the cylinder mixes with the charge of 'highly compressed air therein, and ignites from the vtemperature of the said "compressed air.

the piston in the direction away from the head of the cylinder, and, by reason of the connection of said piston with the Scotch yoke 85, causes the motor to rotate and take up its cycle and run from the power generated within. Vlhen the piston is at the end of the compression stroke, a charge of fresh air (governed by the lip 80 on said piston) enters port 74 under said piston, and is compressed durin the inward stroke of said pis ton, and forcec into the by-pass chambers 63 through the openings 7 When the inward stroke of the piston nears its end, the burned gases exhaust through said port 74, and the ire-compressed charge of fresh air in the said by-pass chambers passes'through openings 76 into the cylinder, and is deflected toward the head of said cylinder by the deflector 79 in the side opposite the port 74:- Constant charges of fresh air are supplied to the head of the cylinder by means of said The rotation of the cylinders obviates the necessity of a fiy-wheel, and creates a con dition adjacent to said cylinders and external thereto resembling a vacuum, which reduces the noise of scavenging the cylinders,-

thus rendering exhaust pipes and mufflers unnecessary. The omission of these parts and of an ignition system, all of which are customary in other motors of this general class, makes a motor embodying this present invention a much cheaper one to'manufac- 'ture than those that have hitherto-been known.

Many minor changes in construction may be made without departing from the spirit of this invention.
