UNITED S TETES PATENT OEEIoE.
l THEOFHILUS MAYHEW, OF YORK, N. Y.
`IMPROVEMENT IN MoToRs.
. Specification forming part of Letters Patent N o. 217,392, dated July 8, 1879; application tiled April 7, 1879.
To all whom 'it may concern Be it known that 1, THEOPHILUsMAYEi-zw, of the city, county, and Stateof New York,
have'invented certain new and useful Im` provements in Motors, of which the following is a specification. llhe object of my invention is to produce a simple, cheap, and serviceable motor adapted for use in churning and various other purposes.
My improvementswill be described as comprised in a motor wherein are a 4flexiblediag phragm, susceptible of being distended by the i 'tion thereof. Fig. 3 is a central longitudinal section of thevalve-chest and valve. Fig. 4 iis a perspective view of the lever and` its appurtenances, whereby motion is transmittedy from the flexible diaphragm. Fig. 5 isa transverse section of one arm of said lever and 5 vextensible arm applied thereto, and appurtenances. Fig. 6 is a detail view of an auxiliary spring-motor and the` rodfof. the valve which it operates.' Fig. 7 is a perspective view of a lever comprised "in the auxiliary spring-motor `afbres aid,`and Fig. 8 is a perspective sectional Aview of a valve-chest and valve `mechanism of modified form.
Similar letters of reference designate corresponding parts in all the iigures.
A designates a chamber, which .may be of concaveform, and is furnished `withla flexible diaphragm, B, of india-rubber, leather, or
Aother suitable material, securedin place by a clamping-ring, C, and bolts a.
D designates aV pipewor conduit communicating with `the chamber A, and serving to conduct steam or other motive agent to and from the same.
E designates a valve-chest communicating with thepipe or 'conduit D, and provided with an induction port orpipe, F, and an eduction `port or pipe, G.
The chamber A, conduit D, and valve-chest E are shown as being made all in one piece,
and with a base-piece or frame, H, whereby they are supported, and this will preferably be effected by casting them together.
Against the side or end of the valve-chest E, with which the induction-pipe F and eduction-pipe G communicate, is fitted a plate of brass or other suitable metal, having openings corresponding to the said induction and eduction pipes, and serving as a seat for a slide- Valve, I. A packing of india-rubber or other suitable material is preferably arranged between the plate and the valve-chest, to preclude leakage, andthe plate is secured in place by screws b. It is obvious that I am enabled by employing this plate to obviate the labor and expense incident to smoothing up the inside of the valve-chest.
The slide-valve I is actuated by abell-crank or elbow lever, Il, consisting of two arms, located one inside and the other outside the valve-chest E, and mounted on a rock-shaft extending through the valve-chest. The arm inside the valve-chest is provided with a T- piece, I2, the body ot' which ts in a cavityin the said arm, andthe arms ot' which fit between lugs f projecting from the back of the valve, and such T-piece is held against the valve by a spiral spring, I3. Thus the radial motion of the lever is compensated for and the valve held to its seat.
In Fig. 8 I have shown the induction and eduction pipes F and G as communicating with a removable cover, secured to the valvechest by screws orv bolts, or otherwise. The valve in this instance consists of an arm, V, extending from a rock-shaft, V', pivoted to the said cover, and limited in its motion by two stops, s, so that it may be swunginto position to cover the inner end of either the induction or edl'iction pipe.
On the outer end of the rock-shaft V is another arm, which is acted upon to shift the valve. The two arms, with the rock-shaft, in
. effect constitute anelbow or bell-crank lever.
J designates a bell-crank or elbow lever, supported by two side frames, S, presently to be described, and having an abutment, J1, on its laterally-extending arm, impinging upon the flexible diaphragm B.
It `will be seen that the face of the chamber A is arranged at an angle to a horizontal plane, and when secured in proper position its face will be radial to the fulcrum of the bell-crank lever J.
The diaphragm, when distended by the mo-k tive agent, impels the lever in one direction, and the weight of the lever or a weight applied to it impels it in the other direction.
It will be observed that the abutment J1 is rigidly affixed to the lever, and that it and the chamber A, to which the flexible diaphragm B is secured, are arranged in planes radial to the fulcrum of the lever J and hence that the said parts operate lin the most advantageous manner possible.
The abutment J1, as also the fulcrum shaft or journals J2, are preferably cast in one piece, so as to be as simple and as little liable to become disordered as possible.
The downwardly-extendin g arm of the lever J sets in motion what I term an auxiliary sprin g-motor,77 whereby the valve I is actuated. This auxiliary spring-motor comprises a lever, K, (shown as triangular in form,) pivoted by a fulcrum-piece, K1, at one end to one ofthe side' frames S, receiving within it a pin or stud, J2, projecting from the downwardlyextending arm of the lever J, and provided at the lower portion with two pinsV or studs, K2, projecting toward the valve-chest, and acting on the lever I1 of the slide-valve I.
L designates a spring, (represented as of spiral form,) suspended from a hanger, M, at a point above the fulcrum of the lever K, and connected to a stud or pin, K3, extending from the lower portion of the said lever K about opposite its fulcrum. As the lever J swings to and fro its pin or stud J3 comes in contact with side pieces of the lever K, and, carrying it past a certain intermediate point in its line of travel, allows "the spring L to retract and complete the throw or swing of the lever with alacrity, and thereby causing said lever, through the agency of one or other of its pins or studs K2, to shift the valve I at the end of the stroke of the lever J and without lost motion.
It will be seen that the spring L serves to shift the valve I in both directions, and as the said spring is arranged outside the apparatus it is readily accessible for adjustment or repairs.
rPhe side frames S are open in the center, and severallyconsist inthis instance of two legs, converging toward and united with an upright body. The pin or stud K3 of the lever K projects between the legs of one ofthe side fram es S, and the latter thus constitutes stops, whereby the movements of the auxiliary springmotor are limited.
Elastic material,V such as india-rubber, may be employed upon the pin or stud K3 or the legs of the said side frame S, to lessen the noise occasioned by the contact of these parts.
'Ihe hanger M, from which the spring L of the auxiliary spring-motor is suspended, is preferably adjustable, so as to cause the spring L to act on the lever K at the proper intermediate point in its throw or travel; and to provide for its adjustment I hang it from the end of a stretcher, S', whereby the upper portions of the side frames S are connected, and clamp it in position against the side frame adjacent to it by a nut, d, applied to the end of the stretcher.
It will 'be seen that by my invention I provide an exceedingly cheap and simple motor,
having few parts, no unnecessary joints, and free from liability to become disordered. In order the better to adapt it for different purposes, I preferably provide the laterally-extending arm of its lever J, whereby motion is transmitted from it, with an extensible arm or section, N. I have shown this extensible section N as grooved on the under side, so as to straddle the top of the laterally-extending arm of the lever J, and as resting at the sides upon longitudinal ribs e; and for securing said section in position I have represented a clamping device, consisting of a frame, 0, surrounding the same and projecting under the longitudinal ribs e, a set-screw, l?, being employed to tighten it.
By loosening the set-screw P the extensible section N may be adj usted or removed at pleasure.
At the outer cndof the adjustable section is a weight, Q, which, of course, is adjustable with the said section, and lugs It, furnished with a cross-pin, whereby the lever may be attached to a churn-dasher or other article.
. What I claim as my invention, and desire to secure by Letters Patent, is-
1. The combination of a flexible diaphragm and chamber and a lever provided with an abutment rextending to said diaphragm, the
said diaphragm and chamber and the said` abutment being located in planes radial to the fulcruln. of the lever. c
