SPECIFICATION forming part of Letters Patent No. 471,766, dated March 29, 1892.

Application filed November 17, 1891. Serial No. 412,176. (No model.)

To a/ZZ whom it may concern.-

Be. it known th'at we, DAVID PATTON BUR- DON and SAMUEL HOUSTON, citizens of the United States, residing at Jacksonville, in the county of Duval and State of Florida, have invented a new and useful Air-Compressor Motor, of which the following is a specification.

-This invention relates to mechanical motors used in connection with air-compressors; and it has for its object to provide a machine which will automatically operate ordinary airengines which are used to maintain appressure for forcing air upon liquids to transfer the same from one vessel to the other, for keeping an equal and steady pressure of air for blast purposes, and for'any other purpose whereit is necessary that a steady and equal pressure should be always employed, and to this end providing mechanism for auto'- matically operating such devices which will maintaina steady pressure at all times within the limit of the power of the machine.

With these and other objects in view, which will be readily apparent as the nature of the invention is better understood, the invention consists in the improved motorand mechanical movements actuated thereby hereinafter more fully described, illustrated in the accompanying drawings, and specifically pointed out in the appended claims.

In the accompanying drawings, Figure l is a side elevation of an air-compressor motor or mechanism constructed in accordance with this invention. Fig. 2 is a top plan View of the same, the escapements and actuating Inotor being detached from the same. Fig. 3 is an end elevation of the machine with the motor removed therefrom. Fig. 4 is a detail elevation of the spring power or motor.

Referring to the accompanying drawings, A represents the bases upon which are supported the opposite pair of air-compression cylinders B, constructed in the usual manner and connected with the devices to which air under pressure is designed to be supplied. The said cylinders are provided with the ordinary pistons and valves, the pistons being connected by the parallel continuous rods or stems C, which connectthe pistons of the opposite cylinders in parallel pairs, and each piston-rod is provided withthe intermediate tappets or shoes D and D', respectively, each of which is provided with the inner square, recessed portions d and CZ', which are engaged by the mechanism to be described, and which actuate, alternately, each continuous pistonrod. Upon suitable supports adjacent to the said cylinders are the stationary transverse shafts E, supported over each end pair of the cylinders and accommodating the large gear-kv wheelsF and F', loosely mounted thereon'and adapted to be revolved by means of the motor located at one end of the cylinders, as illustrated, or underneath, if desired, and connected with the gear-wheel F in the manner which will be hereinafter fully set forth. Each of the intermeshing gear-wheels F and F is provided with the contact friction-rollers G, journaled upon the pins g, projecting alternately from opposite sides of the rims of each wheel. Thev said rollers are arranged upon each wheel, so that those upon one side are alternately disposed with'relation to those upon the same side of the intermeshing wheel, while the rollers upon the opposite side of the wheel are similarly disposed with relation to those upon the same side of the adjacent wheel, which arrangement is for the purpose of securing the proper alternate reciprocation of the piston-rods C' through the medium of the escapement-levers H and H', respectively. The said levers H and H'- are connected .with suitable bearings h and h', which oscillate upon the transverse shaft I, supported in suitable bearings in a suitable frame-work designed for its reception. The said levers are further provided at their extreme lower ends with the outwardly-projecting pins h2, upon which are mounted the friction-rollers h3, that snugly take within the squared recesses d and d' in the opposite tappets D and D', and thereby as the said levers are oscillated cause the alternate reciprocation of the continuous pistonrods. Each of the escapement-levers H and l-l' depends from the shaft I centrally between the intermeshing gear-wheels upon both sides thereof, and secured upon the inner faces are the downwardlyextending and diverging wings h4 and h5, that are engaged by the friction-rollers upon each side of the said gearwheels, and thus cause a swinging or oscillatory motion to be given to the levers. The contact friction-rollers traveling upon said contact-Wings are so disposed that just as the friction-roller upon one side of one of the large gear-Wheels has just left the lowerniost point of one of the Wings andhas thereby carrled the piston-rod to one end of its stroke one of said contact-rollers upon the same side of the adjacent gear-Wheel has just begun its travel down the inclined Way of the opposite Wing of the' same escapemeut-lever, and thereby prevents all jar or click in the movement and provides an alternate continuous reciprocation of said rods, which is further attained by having the contact-rollers disposed, so that when the piston-rod upon one side of the gear- Wheel is at either end of its stroke the oppositel rod upon the opposite side of said wheel is at the center point or midway of its full stroke.

At the end ofthel air-compressors adjacent to the large gear-wheel' F is the spring powertwo large gear-wheels and'mechan ism just described. Upon al suitable base or frame K is centrally mounted thecentral shaft L, car'- rying a drum l, over which the springs Z', f1tti'ng one within the other, are Wound and the free end-s thereof are secured to a suitable adjacent rigid connection, which allowsthe springs to be Wound up and unwound readily.

shaftL is's'ecured the small gear-Wheel M, that same size and mounted upon the stationary shafts n, arranged in a series concentric with the' motion to the central gear-Wheel M, with which the same intermesh. Beyond theinner gear-Wheel M upon the central shaft is mountedthe larger spur Wheel O, which meshes with the pinion P adjacent thereto and rigidly mounted upon the shaft p, which also carries directly back of the pinion P the large beveled gear-wheel Q, which is engaged by the small beveled gear-wheel R, carried upon the innermost end of the shaft S, and Whichis provided upon its outer face with the clutchfr, securely fastened thereto and designed to engage the notched hub of the spur gear-Wheel T, loosely mounted upon said shaft S, and when' rotated by the mechanism described communicates motion to the large gear-Wheel F, With Which the same meshes at one end of the pairs of cylinders.

A collar U is adj ustably mounted upon the shaft S by means of the set-screw u and is designed to form a stop for the coiled spring V, interposed between the same and the outer hub of the gear-Wheel T, and thus normally holds the same into engagement with the clutch r. When it is desired to Wind the motor, the shaft S is rotated by means of a crankhandle applied to one end thereof, and thus through the beveled pinion R communicates motion from the large gear-Wheel O through the various smaller gear-Wheels carrying the actuating-springs referred to, during which Winding the said gear-Wheel T, by means of its ratchet connection With the clutch r, is not revolved; but When it is desired for the motor to Work the tension of the various springs causes motion to be given to the large vcentral Wheel O, Which in turn, through the small pinion and bevel-gear, causes the Wheel vT to revolve and in turn operates the gearj Wheel F, which causes the mechanical movement herein described to op'erate'inl the manner as fully set forth.

Having thus described our iuventiomwhat We claim, and desire to secure by Letters Patent is motor: J, from which motion is impartedvto the l. In a machine of the class described,the
