improved air pump for street cars and analogous purposes', `and it .consists of the constructlon, combination andl arrangement of i saidpin devices hereinafter described and claimed 'and illustrated in .the accompanying drawinOs, iniwhich,
tFigure l is a diagrammatic view showing the'pump applied to the axle of a car. Fig. 2 is a longitudinal section. Fig. 3 is a section on the line 3-3, Fig. 2.
Our invention is designed and adapted to provide a` pump actuated from an axle in ro-. tation.
We 'car out our inventionlas follows: An axle is n icated at a, the same being provided With -a worm b, the worm being referably made in two parts as indicatetF more articularly in Fig. 2, secured to the axle.
ith the worm meshes a gear c upon a shaft d provided with a pin or other connection e eccentrically engaged uponv the gear.. I'Vith is connected a reciprocatory head-f connected with a piston rod g of a piston h working in a` cylinder t, said cylinder being provided with any suitable Ineans of attachment-as a bracket indicated at j, to secure the cylinder in any suitable position on a ear.
It will be observed that as the axle rotates, the worm'meshing with the gear c will cause the gear to be rotated upon its axis d, the head f, through its eccentric connection withthe gear,rbeing rciprocatory to actuate the piston h, in the cylinder i. It will be observed that the device is simple in its construction and operation.
A cylinder 'i is journaled in the bracket j as indicated at k, so-that the mechanism actuated by the worm b may be swung tive position, which may be accomplished in an vsuitable manner, as by the lever Z. 'The cy inder i is carried forward toward the axle to yform an inclosing case for the gear c and heaif with relative parts. The lever mechanis'm l is actuated with said case, as shown. By means ofsaid lever, the said case, with its inclosed parts may. be swung out of activo out of acs 7c. This may be done whenever the air pressure is sufficient in a reservoir m communicating with the cylinder'. The case of the machine is preferably carried forward toward the worm, the same projecting over the extremities of the worm as indicated at n to holdthe case from moving longitudinally of the axle.
What we claim as our invention is:
1. An air pump comprising an worm mounted thereupon, a gear meshing with the worm, a reci )rocatory head eccentrically connected wit the gear, an oscillatory piston cylinder and a piston actuated by the reciprocation of said head, said cylinder forming an inclosing ycase for said gear and said head.
2. An air pump comprising an axle, a worm engage( upon the axle, a gear meshing with the worm, a piston cylinder, and a reciprocatory piston withinnthe cylinder actuated by the rotation of the gear, said cylinder forming an inclosing case for said gear and said head, and projectmg over 'the extremities of the worm to hold the case from moving longitudinally of the axle.
3. An air pump comprising an axle, a worm mounted thereupon, a gear meshing with the worm, a reci )rocatory head eccentrically connected wit the gear, an oscillatory piston cylinder, and a piston actuated by the reciprocation of said head, said cylinder carried forward to form an inclosing case for the gear and head and provided with proaxle, a
engagement with the worm upon the journa 'jecting shoulders on each side oi'l the worm to n hold the case from moving longitudinally of the axle, said gear movable into and out of engagement with said worm.
4. The combination with' an axle of a worm mounted thereupon, a gear meshing with the worm, a reci rocatory head eccentrically connected wit the gear, a piston cylinder, and a piston actuated by the reciprocation of said head, said cylinder having a jointed engagement with a suitable supportat one extremity thereof, and means to throw the gear out of engagement with the worm.
ln testimony whereof we have signed this specification in presence of two witnesses.
