Specification of Letters Patent.

Patented March 12, 1907.

To atZZ whom it may concern.-

Be it known that 1, WILLIAM HUGHES, a citizen of the United States, residing at Sharon, in the county of Mercer and State of Pennsylvania, have invented new and useful Improvements in Motors, of which the following is a specification The invention relates to an improved motor of the type known as a weight-motor, in which the weights are so disposed as to impart a continuous operation to provide power.

The main object of the present invention is the production of a weight-motor constructed for operation by the use of do licate weights arranged to successively in uence the motor and to be carried beyond the deadpoint in normal gravitation by the use of auxiliary power.

The invention will be described in the following specification, reference being had particularly to the accompanying drawings, in which- Figure 1 is a side elevation of amotor constructed in accordance with my invention. Fig. 2 is a vertical central section of the same with the parts disposed in a position gained by the maximum effect of the operatingweight. Figs. 3 to 10 are diagrammatic views illustrating the successive positions of the weights in one complete revolution of the frame, Figs. 3, 5, 7, and 9 being end views and Figs. 4, 6, 8, and 10 being plans, respectively, of the parts, as shown in Figs. 3, 5, 7, and 9.

Referring particularly to the drawings, wherein like parts are indicated by similar reference-numerals throughout the several views, my improved motor comprises standards 1 of any desired type, preferably suported in spaced relation upon a suitable base structure 3. Intermediate the standards 1 and 2 and revolubly supported therein is the movable or operating member of the motor, comprising in its preferred form a frame-like structure including spaced side bars 5, united at their respective ends by heads 6, from which heads project trunnions 7, revolubly mounted in bearings 8, formed in the standards. At the end adj acent the standard 1 the frame immediately adjacent the head 6 is in the form of a casing 9, that the side bars 5 of the frame are united by transversely-arranged webs forming, with the side bars, a cylindrical casing closed by the head 6 and open at the opposite end. A

cylinder 10 is secured within the casing 9, being provided at the end approximate the open end of the casing with a head 11, centrally formed for the passage of a piston-rod 12, the usual packing-rings and stuffing-box 13 being employed to revent leakage. A piston 14 is disposed within the cylinder and connected to the end of the piston rod 12, and the wall of the cylinder about midway its length is formed with an exhaust port 15, communicating with an opening in the wall of the casing to provide for the escape of the motor fluid utilized in operating the piston. The trunnion 7 of the frame, which is mounted in a standard 1, is hollow to provide a steampassage 16, which passage communicates with a laterally-disposed channel 17, arranged in the approximate head 6 of the frame and in communication with the interior of the cyhnder through a longitudinallydisposed port 18, formed in the wall of the casing and opening into the cylinder at the relatively forward end of the latter, all as clearly shown in Fig. 2. The mouth or inlet end 19 of the steam-passage 16 is eccentrically disposed relative to said passage, and secured within the bearing 8 in the standard 1 is the end of a steam-supply pipe 20, the free end of which is fixed within the bearing and designed to abut the end of the trunnion 7. The outlet 21 from the steampipe is also eccentrically disposed relative to said pipe, the arrangement being such that steam is admitted to the passage 16 only when the outlet 21 of the pipe 20 and inlet 19 of the trunnion are in register, any other relative position of the trunnion offsetting said openings and preventing passage of steam.

The side bars 5 of the frame 4 are connected in advance of the center of the frame relative to the standard 1 by a bearing-shaft 22, on which is supported for revolution a sleeve 23. Arms 24 are secured at their inner ends to the sleeve 22 being provided at their outer ends with weights 25, the length of the arm and weight being such that when the latter is in normal position between the side bars of the frame the free edge of the weight rests immediately adjacent the approximate head 6 of the frame, thereby giving the weights the maximum effect.

The arms 24 are disposed at a right angle to each other, so as to include approximately one-fourth of the circumference of the sleeve between the weight-arms, and it is impor- I the sleeve, and projecting in a direction optant, as will be evident from the following 1 description, that the relative position of the weight-arms should be so disposed as to form a right angle with each other. A lug 26 projects radially of the sleeve 22, being arranged at a point diametrically between the point of connection of the arms 24 and positethe projection of said arm. A link 27 connects the relatively free end of the piston 12 with the lug 26.

As thus constructed the controlling-weights of the motor project at a right angle to each other, so that when one of the weights is in its most effective position, beyond and below the frame 5, the other weight will lie in alinement with and in the plane of the frame. The lug 26, whereby the piston communicates movement to the sleeve 22, projects from said sleeve on the diametric line thereof, passing through the sleeve intermediate the arms 24, so that one-fourth of the sleeve circumference is included between the weight-arms, while approximately threeeighths of the sleeve circumference is inpluded between either of said arms and the In operation, assuming the parts disposed as shown in Fig. 1, with the frame-bars 5 arranged in vertical alinement, in which position the weights 25 are in the same horizontal plane. Steam is now admitted to the passage 17, it being understood that the respective openings are in register. The steam traveling through the ports referred to will operate upon the piston 14 and move the same toward the standard 1. This exerts a pull upon the lug 26, with the effect to move the weight then resting in alinement between the side bars of the frame outward beyond said bars, and through the resultant gravitation cause a revolution of the frame. This movement causes a half-revolution of the frame, with the effect to dispose the second weight in the position previously occupied by the first weight. During such revolution the steam has been cut off from the cylinder and the movement of the operating-plate 25 has redrawn the piston to normal position, the accumulated motive power exhausting through the cylinder from the port 15. As the frame has made a half-revolution the second weight will be disposed in the position previously occupied by the first weight, whereupon steam is again admitted to draw upon the lug 26 and project the second weight beyond the frame for operation.

It is to be particularly noted that the weights do not make a complete revolution about the shaft 22, but that they simply move from the normal position between the frame-bars to a projected position beyond the same, and thereupon gravitate to cause a revolution of the frame on its trunnions.

same

This revolution of the frame raises the projected weight into a horizontal plane with the frame, and the similar operation of the second weight returns the first weight over the previously-operated path, again disposing it in normal position for initial actuation by the piston."

As the steam is admitted only at predetermined intervals to carry the operating weights beyond the dead-point, it is obvious that the motor, with the exception of the initial movement resulting from the admission of the steam, is operated solely by the weights.

lteferring particularly to Figs. 3 to 10, wherein is shown diagrammatically the successive positions of the respective weights in a complete rotation of the frame, said weights being referred to as A and B, respectively, it will be noted that in Fig. 3, which illustrates the initial position, the weight A has been projected beyond the plane of the frame, while the weight B remains within said plane. Weight A will therefore by gravity exert a rotating pull on the frame, causing A to move downward until immediately below the pivot-support of the weights, as shown in Fig. 5. 1n this position the weight B is still within the plane of the framethat is, exerting no power or pull thereon. The inertia gained by the frame in the fall of the weight in the position shown in Fig. 3 to that shown in Fig. 5, will vcarry the frame and weight partly upward beyond its lowermost point, as shown in Fig. 7. In this position, as will be noted from Fig. 8, the weight B still remains in a normal or inactive position. Steam is admitted to the piston at this point in the operation to force the weight A into longitudinal alinement with the frame or the inactive position. This movement forces the weight B beyond the plane of the frame, as clearly shown in Fig. 9. As the inertia of weight A has carried said weight, and therefore the frame, beyond the lowermost point, due to the gravitation of the weight, it is evident that weight B when projected beyond the plane of the frame will be beyond the uppermost point possible, hence in a position to exert a pull upon the frame. As weight A has. simultaneously with the projection of weight B been withdrawn into parallel relation to the frame or inactive position, there is no counterbalance for the weight B, and hence the latter will continue the rotation of the frame. This operation being repeated in each revolution of the frame, it is obvious that the weights will be successively projected into active position at the particular moment when their force may be directed to a continuation of the revolution of the frame, the opposing weight being simultaneously withdrawn into inactive position.

The trunnions 7 having bearing in the standard 2 is designed to be connected to communicate power derived from the motor to any mechanism, a simple form being shown wherein the trunnion is extended and provided with a gear 28, arranged to mesh with a gear 29, mounted on a stud-shaft 30,

supported in the standard 2 and carrying at its outer end a belt-wheel 31 for communicating the power derived.

Having thus described the invention, what is claimed as new is- 1. A weight-motor comprising a frame mounted for revolution, weights connected together and arranged at an angle relative to each other, and auxiliary means for imparting an initial movement to the weights, said means being operative to project the weights in succession beyond the plane of the frame, whereby to utilize the weights for imparting a movement to the frame.

2. A weight-motor comprising a frame mounted for revolution, connected weights movably supported in the frame and arranged at the angle with respect to each other and means for imparting initial movement to the weights in succession, said means being operative to simultaneously project one of the weights beyond the frame and move the other weight in the plane of the frame-axis.
