SPECIFICATION forming part of Letters Patent No. 345,101, dated July 6, 1886.

Application filed May 24, 1386.

To LZZ whom, it may concern.-

Be it known that I, BLUM-r C. BARTON, of East IIampton, in the county of Middlesex and State of Connecticut, have invented certain new and useful Improvements in Gong- Bells, of which the following is a'full, clear,

and exact description,wh ereby any one skilled in the art can make and use the same.

My improvement relates, particularly, to` the class of gong-bells known as singlestroke;77 and my object is to provide such aV bell of simple, compact, and efficient construction.

Referring to the drawings, Figure lisa plan view of my improved bell with part of the gong broken away to uncover the baseplate. Fig. 2 is a similar plan viewof the bell, but showing the slide drawn out and about to trip the hammer to cause it to strike. Fig. 3 is a side view of the base-plate and parts attached, gong in central section'.

In the accompanying drawings, the letter A denotes the cast-metal base-plate of the bell 5 B, the gong, that is attached to the post c in any ordinary manner, as by screwing it onto the top of the post, with the edge of the gong in position to receive the stroke ofthe hammer.

The base -platc A supports the bell-post, about which is coiled the spring d, with its ends projecting toward opposite sides of the plate, the one end being pivoted to the con necting-rod c, that joins it to the shorter arm of the hammer-leverf, while the other end of the spring is pivotally connected to the slideg by means ofthe link er rod c'.

The slide g is a flat piece of metal with a lengthwise slot, g', through which a screw passes to attach it to the base-plate, the head of the screw gi overhanging the sides of the slot, so as to prevent the slide from lifting off from the plate, and causing it to move in a plane practically parallel to the base plate, the screw g2 serving also, by contact with the ends of the slot, tolimit the endwise movement ofthe slide.

The link or rod c is connected io the slide r1 at a point offset from the slot or the line of it, in order to cause the pull of the spring, through the medium of the rod e, to throw Serial No. 203,057. (No model.)

`the slide sidewise as well as lengthwise. The slide bears a projecting catch, h, with its face inclined at an angle with the slot g', and its edge adapted to engage the short arm of the hammer lever, the back side of this endf being rounded or inclined.

The hammer-lever f is pivoted to the baseplate, so as to swing in the plane of the plate, with the shorter arm of the lever extending over the slide and in the path of the catch as the slide is pulled outward, as shown in Fig. 2 of the drawings. In Fig. l the parts are shown in full lines in their normal position, held so under the tension of the spring, while in Fig. 2 the slide is shown as pulled outward until the edge of the catch is on the point of slipping .off the end f of the ham; mer-lever, and after the catch and hammerlever are disengaged the hammer recoils un der the pull of the spring and strikes sharply against the gong. The slide, on being relieved from the outwardl pull, is pulled in ward by the same spring, and swings aside on the screw gi as a pivot by the contact of the sloping surface of the catch and the rounded end ofthe hammer-lever (see this position of the slide in dotted outline in Fig. 1) until the edge of the catch isreached, when the slide is swung sidewise by the pull of the spring, and the catch and hammer-lever reeugaged and in position for causing another blow of the hammer when the slide is pulled out. In order to prevent the strain from breaking off the screw g2, the stop a is east upon the base-plate in position to be struck by the side projection on the slide just before the end of the slot would strike the screw but for this limitation of the play of the slide.

The principal advantage of the within-described combination of elements in the striking mechanism of the bell is due to theJ piv otal connection of the slide and the hammerlever with the spring by means of the links or connecting-rods.

I am aware that it is not new to use a single spring in bells of this class, and utilize both ends to operate the hammer and the slide, and also that slides with both endwise and sidewise play are not new, and suehdevices I do not broadly claim.
