MOTOR.
SPECIFICATION forming' part of Reissued Letters Patent No. 9:8(34, dated July 12, 18.81. original No. 217,392, dated au-8,1819. Application fer reissue inea May 28,1891.
To all whom lit may concern: A
Beit known that I, THEOPHILUS' MAYHEW, of Poughkeepsie,in the county of Dutchess and State of New York, have invented certain new and useful Improvements in Motors; and I do.
xo being had to the accompanying drawings, and' to the letters of reference marked thereon, which form a part of this specification.
The object of my invention is to produce a simple, cheap, and serviceable motor, adapted 15 for use in churning and for various other purposes.
My improvements will be described as comprised 1n a motor wherein are a flexible dia-4 phragm susceptible of being'distended by the Q pressnreofsteamor other motive agent under` controlV of a valve, and a lever impelled by the vdiaphragm and actuating the valve. 1' In the accompanying drawings, Figure 1 is a side view 4ofa motor embodying my'iinprovez 5 ments. Fig. 2 is a central longitudinal section thereof.' Fig. 3 is a central longitudinal seetion of the valve-chest and valve. Fig. 4 is a perspective view of the lever and its appurte- Dances, whereby motion is imparted from the 3o flexible diaphragm. Fig. 5 is a transverse section of one arm of said lever and exten sible arm applied tliereto and appurtenances. Fig. 6 is a detail view of an auxiliary spring-motor and the rod of the valve whichjt operates. Fig. 7 is a perspective view of alever comprised in the auxiliary spring-motor aforesaid, and Fig. 8 is a perspective sectional view of a valvel" chest and valve mechanism of modified form. Similar letters of reference designate corre- 4o sponding parts in all the figures.
A designates a chamber, which may be of concave form, and is furnished with a exible diaphragm, B, of india-rubber,leather,'or other suitable material, secured in place by a clampjing-ring, C, and bolts a.
D designates a pipe or conduit communieating with the chamlJer A, and serving to conduct steam or other motive agent to and from the same.
5o E designates a valve-chest communicating valve, I.. A packing of india-rubber or other employing this plateto obviate the 'labor-and with the pipe or conduit D, andprovided with an induction port or pipe, F, andan eduction pipe or port, G. p
The chamber A, conduit D, and valve-chest E are shown asbeing made all in one piece, and with a base-piece orframc, H, whereby they are supported,'and this will preferably be e'ected bycasting4 them together.
Against the side or end of the valve chest E, with which the induction-pipe Fand educ- 6o tion-pipe G communicate, is fitted a plateof brass or other suitable metal, having openings corresponding to the said induction and eduction pipes, and serving as a seat for a slide- 6 suitable material is preferably arranged be' 5 tween the plate and the valvechest,-to preclude leakage, and the plate is secured in plaeeby screws b.. It is obvious that I am enabled by O expense incident lto smoothingr up the inside 7 of the valve-chest.` Y
The slide-valve I is actuated by'a bell-crank o r elbow-lever, I', consisting of two arms located one inside and the otheroutside thevalvechest E, and mounted on a rock-shaft extending through the valve-chest. The arm iriside the valve-chest is provided with a T-piece, I. the body of which lits in a cavity in the said arm, and the arms of which tit between lugs 8o f, projecting from the back ot' the val\'e,`and
such T-piece is held againstthe valve by a spiral spring, 13. Thus the radial motion ot' .the lever is compensated for and the valve held to its seat.
In'Fig. S I have shown the induction and eduction pipes F and Gas communicatingr with a removable cover secured to the valve-chest by screwsor-bolts or otherwise. The valve in this instance consists ot' au' arni, V, extend- -ing from a rock-shaft, V', pivoted to the'said cover, and limited in its motion by two stops, S, so thatrit may be swung into position Ato cever the inner end of either the induction or eduction pipe. 95
On the outer end of the rock-shaft V is another arm, which kisacted upon to shift the valve. The two arms, with the rock-shaft, in effect constitute an elbow or bell-crank lever. y -f J designates aboli-crank or elbow lcve,1,sup roo SSP ported by two side frames, S, presently to be described, and having an abutment, J', on its laterally-extending arm impingin'g upon the exible diaphragm B. y
It will be seen that the face of the chamber A is arranged at an angle to a horizontal plane, and when secured iu proper position its face will be radial to the fulerum'of the bell-crank lever J. The diaphragm when distended by the motive agent impels the lever in one direction, and the weight of the lever or a Weight applied to it iinpels it in the other direction.
It will be observed that the abutment J' is rigidly aixe'd to the lever, and that 'it and the chamber A, to which theV flexible diaphragm B is secured, arearranged in planes'radial to the fnlcrum of the lever J, and hence that' the said parts operate in the most advantageous manner possible.
y The abutment J,'as also the fulcrum shaft or jsjirnals J 2, are preferably cast in one piece,
so as to be as simpleand as littleliable to become ldisordered as possible.
` AThe downwardly-extending' arm of the lever J sets' v in motion what I terni an auxiliary spring-motor, whereby the valve I is actuated. This auxiliary spring-motor comprises a lever,
K','(shown as triangular in form,) pivoted by a.
-fulcrum-piece, K', at one end to one of thc side 3o frames, S,'receivin g within itapiu or stud, J3,
projecting from the downwardly extending t arm ofthe lever J, and provided at the lower portion with two pins or studs, K2, projecting toward the valve-chest, and acting on the le,
ver I' of thc slide-valve I.
LY designates a spring (represented as of spiral forni) suspended from a hanger, M, at a. point above the fulerum of the lever K, and connected to a stud or Vpin,'K=, extending from 4o thel lower portion of the said lever K about opl posite its t'ulcruni. As the lever J swings to and fro its pin or studJ 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, thereby causing said lever, through the agency of one or other of its pins or studs K, to shift the valve-I at the end of the stroke of 59 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 asthe said spring is arranged outside the apparatus it i s readily accessible for adjustment or reairs.
The side frames, S, are `open in the center, Vand severally consist in this instance of two legs converging toward and'united with an upright body.. ,The pin or stud K" of the lever K projects betweenl thelegs of one ofthe side frames, S, and the latter thus constitutes stops, whereby the 'movements of vthe auxiliary spring-motor are limited. f
" vLllastic material, suoli as india-rnbber,f1nay be employed upon thepin or'stud K, or the soa The hanger M, from which-the spring L of the auxiliary spring-motor is suspended, is preferably adjustable Aso as to cause the spring L to acton the lever K at the proper intermediate point in its throw or travel, and to provide for its adjustment I Vhang it from the end "of a stretcher, S', whereby th'e upper portions of the side frames, S, are connected and clamp -it in position against the side frame adjacent toit by a nut, d, applied to the end of the stretcher.
It will A be seen that by my invention I provide an exceedingly 'cheap and simple nmtor, liaving'few parts, no unnecessary joints, and free from liability to become disordered. In order the better to adapt it for dierent 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 secstraddle the top of the laterally-extendin g arm of the lever J, andas resting at the sides upon longitudinal ribs e and for securing said section iu position 1 have represented a clamping device consisting of a frame, 0, surrounding the same and projecting under the longitudinal ribs c, a set-screw, P, being employed to tighten it.
By loosening the setserew I the'extensible section N may be adjusted or removed at pleasure.y v
At the outer end of the adjustable section is a weight, Q, which, ofcourse, is adjustable with the said section, and lugs R furnished with a cross-pin, whereby the lever may be attached to a churn-dasher or other article.
seen that the essential features of the device are a body or surface arranged to receive and to bc'moved by the pressure'of the motive agent avibratory lever actuated thereby, -a valve foriregulating the entrance and exit of the motive agent, and a spring or other auxand serving to operatefthe valve.
it is apparent that any recognized mechanical equivalent of the weight may be-employed'.
