JOHN H. BONSTEEL, OF NIAGARA FALLS, NEW YORK.

MOTOR.

SPECIFICATION forming part of Letters Patent No. 669,502, dated March 12, 1901.

Application led August 6, 1898. serial No. 687.974. (No model.)

To all whom it may concern:

Be it known that I, J oHN H. BoNsTnnL, a resident of Niagara Falls, in the county of Niagara and State of New York,have invented certain new and useful Improvements in Motors; and I do hereby declare the following to be a full, clear; and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

My invention relates to an improvement in motors, and more particularly to such as are adaptable for use with fluids-such as water, air, steam, or gas-as the motive power, one object of the invention being to so construct a rotary motor that the valves or pistons will open or move into position to beacted upon to drive the motor in the same direction as that of the source of power, and thus avoid a serious defect in prior motors, where the pistons must open or move against the pressure of the motive power before they can be propelled thereby.

A further object is to so construct the motor as t-o permit adequate expansion in the stroke between the time the power is cut off and the time of the exhaust when gaseous fluid is used as the motive power.

' A further object is to provide a rotary 1'no tor having hinged pistons, with means to prevent the clicking noise after the pistons shall have passed the exhaust.

A further object is to produce a rotary motor which shall be simple in construction, not liable to get out of order, cheap to manufacture, and which shall be effectual in all respects in the performance of its functions.

With these objects in View the invention consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical sectional View of my improved motor. Fig. 2 is a vertical cross-section. Figs.

3 and 4 are detail views, and Fig. 5 is a View showing arrangement of motors for use with low fall of water.

A represents the outer or stationary casing of the motor and comprises disks 1 2, each having feet 3, by means of which to support the motor on a suitable base, and a ring 4,-

disposed between said disks, suitable packing being preferably disposed between the edges of said ring and the faces of the disks to prevent escape of water, steam, or other fluid which may be employed as the motive power, and said disks and ring are secured firmly together by means of suitable bolts. The ring 4 of the casing is provided with an elongated recess 5, divided to form a double port 9 9, and with one end of said elongated recess a feed-pipe 6 communicates, said feed-pipe being preferably made conical in form, with its smaller end communicating with said elon: gated recess. An exhaust-port 7 is made in the ring 4 and commences where the stroke of the motor finishes and extends around some distance, so as to terminate a comparatively short distance from the inlet-port.

Within the casing A a revoluble cylinder B is disposed, said cylinder having one end open and having a peripheral series of long ports 10, and thus each end of the cylinder is formed with a narrow ring 11 12, respectively, said rings being connected at intervals (between the ports and separating the latter) by means of transverse portions 13. The ring 11 ofthe revoluble cylinder is mounted to revolve in an annular groove 14 in the inner face of the disk 1. The ring 12 at the other side or end of the cylinder is made in the form of an annular flange projecting inwardly from the head 15 of said cylinder, and within said flange a disk 16 is disposed parallel with the disk 2 of the casing. Thus it will be seen that while one end of the revoluble cylinder is mounted in the annular groove 14 of disk 1 the other end of said revoluble cylinder is mounted to revolve on the disk 16, disposed alongside the disk 2 of the casing.

The shaft 17 of the motor may be secured to the end or head 15 of the revoluble cylinder and may have a single bearing in the disk 2 of the casing, or, if desired, said shaft may be extended through the motor and have an additional bearing in the disk 1 of the casing. The disk 16 serves as a solid side Wall to prevent side pressure on the shaft and renders a stuffing-box unnecessary. An enlargement C, having a curved face 18, is secured to or formed on the stationary disk 16, so as to be disposed within the revoluble cylinder1 to one side of the axis of the shaft 17, and is IOO adapted to extend to the inner face of said revoluble cylinder. In case the shaft 17 is extended through the cylinder B it may form a seat for the feet of the pistons; but if the shaftbe secured to the stationary disk 16 the inner end 19 of the enlargement will be in line with said shaft, practically concentric therewith, and will form said seat.

One end ot' a piston, valve, or wing 2O is pivotally mounted in one end .of each port 10 f the revoluble cylinder B,- and each piston, valve, or wing is of a length somewhat less than the length of the port l0 in which it is mounted. The end 2l of the enlargement terminates in proximity to the inlet end of the inlet-port, and said inlet-port may he somewhat shorter than the ports 10 in the revoluble cylinder. In other words, the length of the elongated feed and ports in the revoluble cylinder are relative to the stroke required.

It will be observed that the enlargement C constitutes an eccentric abutment for the inner ends of the wings or pistons and that the end 21 of said abutment being disposed in proximity to the inlet-port a wing or piston will, as soon as its free end passes the end 21 of the abutment, be forced inwardly by the pressure of the fluid motive power entering bythe ports 9 9 and made to engage the inner end of the abutment or enlargement, (or shaft 17, if the latter bepassed entirely through the cylinder,) and thus a chamber is formed having the face 22 ot' the abutment for one wall and the wing or piston for the other wall. The abutment being stationary and the wing or piston being mounted in a revoluble cylinder, the latter must turn when pressure is thus applied. It will be observed that the Wings or pistons will remain closed until the free end of the Wing or piston passes the end 21 of the abutment, when it will be forced open by the pressure of the Huid motive power and form a piston against which said motive power acts,as above explained. The wings or pistons are thus opened bythe pressure of the motive power in the same direction in which the latter moves or flows, and that as soon as they take the proper position to act as pistons they automatically cut otf the motive power from beyond the chamber of which they constitute the moving wall. As' the cylinder continues to rotate by the pressure against a piston,as above explained, the port in which said piston is mounted will iinally reach the exhaust-port, when the Huid-pressure contained in the chamber of which said piston forms a wall will escape through the exhaustport. After passing the exhaust-port (pressure having been relieved from the piston) said piston will ride on the eccentric face of the abutment and be thereby forced outwardly, so that when the piston reaches the end 21 of the abutment it will be concentric within its port 10 and ready to be again acted upon as soon as its free end shall have passed said end 21 of the abutment, as above explained. It is apparent that the several pistons will act successively in the manner above explained.

It has been found in practice that after a piston leaves the exhaust-port it will in assuming a position within its port 10 concentric with the cylinder B cause a clicking noise, which is objectionable. In order to prevent this, I employ a jet-pipe 25, which communicates at one end with the inlet or feed passage to the motor and at the other end with the interior of the casing of the motor, so as to form a cushion to receive the piston after the latter leaves the exhaust-port.

My improved motor may be operated by means of wat-er as the motive power; but it is just as efficient with steam, air, or gas as the motive power.

In cases where it is desired to employ the motor with a low fall of water two revoluble cylinders will be employed and arranged as shown in Fig. 5.

Various slight changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope, and hence I do not wish to limit myself to the precise details herein set forth. i

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
