Specification of Letters Patent.
Patented liiiar. 31., 1914.
Application filed September 11, 1912. Serial No. 719,766.
It is the obect of the invention to obtain a simple and eiiicient construction, in which a large bell may be operated with small ex penditure of energy.
To this end the invention consists, first, in the peculiar construction of a pendulum hammer and operating mechanism therefor, and further in various features of construction as hereinafter set forth.
In the drawings: Figure 1 is a front ele vation showing the pendulum hammer and operating mechanism; Fig. 2 is a perspective view of a portion of the mechanism; Fig. 3 is a plan view; and Fig. i is a side elevation with the cover in section.
A is a suitable frame or bracket, upon which is mounted the bell B.
C is the electro-magnet for operating the bell, which is mounted within a recess in the upper portion of the frame A.
D is a hinged armature which is mounted in a bracket E upon vertical pivots F and F, and is adapted to be moved laterally whenever the magnet is energized.
The hammer for the bell is in the form of a pendulum, which is hung upon and carried by the armature D. This pendulum G is fulcrumed upon a horizontal pivot I-I, secured to the bracket E, but the weight of the pendulum is sustained by the hinged armature. As shown, the pendulum has at its upper end the laterally bent portion I, which engages bearings in cars J upon a member K, which is sleeved upon a vertically extending pin L on the armature. Upon the fulcrum pivot H is sleeved a member M, having ears N slidably engaging the downwardly extending portion of the pen dulum. Thus whenever the magnet is energized and the armature swung upon the vertical pivots F, the pin L and member K will actuate the bent portion I of the pendulum G, while the pivot H and member M will determine its path of movement. On
accountof the sliding engagement between the oendulum rod and the ears N of the member M, and also the slidable engagement between the laterally bent portion I and the ears J, the pendulum will move without any binding due to the difference in directions of movement of said parts. Thus the member K being supported upon the armature will move therewith in a horizontal plane, carrying the portion I of the pendulum through a similar path. On the other hand, the member M will move angularly about the pivot I-I, imparting to the ears N a movement through a segmental path; consequently there will be a longitudinal sliding movement of these ears upon the pendulum rod. In the same way the angular movement of the pin L and member K about the axis of the pivots F will cause a sliding of the ears J upon the portion I, the effect being to produce a universal coupling between the pendulum and the armature, which avoids all binding and friction of the parts. The lower end of the pendulum is provided with a suitable hammerhead O, which under the pull of the armature will impinge against the bell and produce the sound. The magnet, armature and connecting mechanism is housed by a casing P secured to the frame A, and having a skirt Q overlapping a portion of the bell.
What I claim as my invention is:
1. In a bell, the combination with an electro-magnet, of a pivoted armature, a pendulum hammer supported upon said armature, a stationary fulcrum, and universally pivoted connections between said pendulum and armature and pendulum and fulcrum.
2. In a bell, the combination with an electro-magnet, of a pivoted armature, a pendulum hammer supported upon said armature and movable therewith, a fixed fulcrum, and connections between said pendulum and ar mature and pendulum and fulcrum, permitting a universal movement between the pen dulum and armature.
3. In a bell, the combination with an elecfro-magnet, of an armature therefor supported upon vertical pivots, a pendulum hammer supported upon said armature, a stationary fulcrum and universally pivoted connections between said pendulum and armature and pendulum and fulcrum.
4. In a bell, the combination with an electro-magnet, of an armature therefor supported upon vertical pivots, a pendulum hammer having a laterally extending portion supported upon said armature and movable therewith, a fulcrum pivot, and a slidable connection between said fulcrum and pendulum.
5. In a bell, the combination with an electro-magnet, of an armature therefor supported upon vertical pivots, a pendulum hammer having at its upper end alaterally bent portion, a member slidably engaging said laterally bent portion of the pendulum, and vertically pivoted upon and supported by said armature, a stationary fulcrum pivot, and a slidable connection between said fulcrum and pendulum.
6. In a bell, the combination with an electro-magnet, of a hinged armature supported upon vertical pivots, a vertically extending pin on the free end of said armature, a member pivoted on said vertical pin and extend ing laterally therefrom, a pendulum hammer having a laterally bent portion slidably and pivotally engaging bearings in said laterally extending member, a stationary fulcrum pivot, a member sleeved upon said pivot and having a bearing slidably engaging said pendulum.
7. In a bell, the combination with an electro-magnet, of a hinged armature supported upon vertical pivots, a pin extending vertically from the free end of said armature, a horizontally extending fixed fulcrum pin, members respectively pivoted upon said vertical and horizontal pins, and provided with transversely extending bearings, and a pendulum hammer having a laterally extending portion slidably and pivotally engaging a bearing on one of said members, and having laterally extending portion of the pendulum,
a horizontally extending, fixed fulcrum pin, 7
and a member sleeved upon said fulcrum pin having a laterally extending port-ion provided with struck-up ears pivotally and slidably engaging the depending portion of said pendulum hammer.
9. In a bell, the combination with a frame, a sound-producer mounted thereon and an electro-magnet mounted on said frame above said sound-producer, an armature mounted on vertical pivots on said frame, a pendulum hammer having a laterally bent portion at its upper end, a horizontally extending, stationary fulcrum for said hammer, universal, pivotal connections between said laterally extending portion of said hammer and said armature, and between the downwardly extending portion of said hammer and said fulcrum pin, and a housing for inclosing said parts and overlapping said bell.
In testimony whereof I afiix my signature in presence of two witnesses.
