snac'rnomennnc LDCOMOTIVE BELL anmsn Filed 1 m 4, 1928 2 Sheets-Sheet 2 djZBea'a'anMmR ATTORNEY Patented June 10, 1930 UNITED STATES PATENT OFFICE GEORGE M. BESSANT, or SAN minnarwmo, .cauroamm ELECTROMAGNETIC LOCOMOTIVE BELL BINGEB Application filed April 4,
ing its core connected with the crank of the hell, with automatic means for breaking the circuit of the magnet on the upward stroke of the bell so that the bell will drop under the action of gravity and close the circuit again, thus causing the magnetic means to again swing the bell upwardly, but in an opposite direction from its first upward stroke.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.
In describing my invention in detail, refer ence will be had to the accompanying draw ings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a sectional view showing the invention in use.
Figure 2 is a view taken at right angles to Figure 1 with the bell omitted, but showing the crank of the bell.
Figure 3 is a section on line 33 of Figure 1.
In these views, the numeral 1 indicates the magnet which is provided with the usual armature 2, a magnet being supported by the bracket 3 which has a hole therein through which passes the rod 4, preferably of bronze, which is connected with the upper end of the armature and a connecting rod 5 is pivotally connected with the upper end of the rod 4 and is flexibly connected with the crank 6 of the bell 7 through means of the housing 8 connected with the upper end of the rod 5 and enclosing the crank and slidingly receiving the bearings 9 of the crank and carrying the springs 10 which are arranged above and below the bearings. These springs act as shock absorbers for absorbing the shocks produced by the swinging of the bell. The springs are held in place by the bosses 11 at the ends of the housing.
A rod 12 is slidably arranged in the guide- 1928. Serial No. 267,382.
The impulses imparted to the bell by the magnetic means may be adjusted to the natural swing of the bell by adjusting the collars on the rod 12.
It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.
It is to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.
What I claim is A reciprocating motor comprising a magnet, a supporting bracket therefor, an armature having a threaded bore, a rod having a reduced extension threaded in said bore and providing a connection between the armature and a member to be operated, a circuit 10 for the magnet, a stationary contact arranged in the circuit, a second rod arranged at one side of the magnet, a substantially U-shaped guide for the second mentioned rod supported by the bracket for the mag- 15 net, the parallel portions of said bracket having aligned openings to slidably receive said rod, a plunger-like Contact carried by the lower end of the rod and engaging the first contact when the rod is in lowered po- 20 sition, a pair of spaced adjustable collars carried by said rod, and characterized by projections extending in the direction of the magnet, and an arm carried by the first mentioned rod and operating between said collars to alternately contact the projections thereof for the purpose specified.
In testimony whereof I afiiX my signature.
GEORGE M. BESSANT.
