TO ALL WHOM IT MAY CONCERN:

Be it known that I, JAMEs HARRISON, of the city of New York, in the county and State of New York, have invented a new and useful Mode of Mounting Bells; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed two sheets of drawings, making a part of this specification, i'n'which- Figure 1, on sheet 1, is a perspective view of the bell and mountings, complete.

Figure 2, on sheet 1, is atop view, showing the combination of lever m and cam k, with the working pawl J working into ratchet-wheel H, and gear-wheel 1 working into gear-wheel g', and gear-wheel F working into gear-wheel e, and screw or worm-wheel cl working into the large gear-wheel C.

Figure 3 shows cam is, with lever m. I

Figure 4 the joint in which it works.

Figure 5 shows the working lever J, with the working pawl J".

Figure 6 the check-spring s.

Figure I, on sheet 1, is a perspective view of a bell, with a piece broken out, in order to show the application of the same combination of gears applied to the hammer inside the bell instead of outside the bell, as shown in fig. 1.

Figure 8 is a front view of ratchet-wheel g, and gear-wheel F working into gear-wheel d, and screw gearwheel e working into large gear-wheel D, as shown in fig. 7. The swinging of the hammer from one side of the bell to the other gives a backward and forward motion to the working pawl I, which causes the ratchet-wheel g to move round forward, and is prevented from moving backward by the check-dog J; thus the continued swinging of the hammer effects the rotation of the clevis c to which the clapper is connected.

Figure 9 is intended to show the yoke B, with a little difi'erentcombination of gear-wheels, arranged'hori zontally, as shown, and set in motion by the action of cam or eccentric k, and pawl J. working into ratchetwheel I. The bell is made fast to the gear-wheel C,'as shown in fig. 1.

Figure 1, on sheet 2, is a perspective view of bell and mountings, complete, same as fig. 1 on sheet 1, only showing a less combination of gear-wheels, intended only for small bells. 0

The figures from No. 2 to No. 13, on sheet 2, are intended to show parts of fig. 1 on sheet 1 and of fig. 1 on sheet 2, the same being applicable to both.

Figures 2 and 3 are nuts.

Figures 4 and 5 are washers.

Figure 6 is the middle portion of yoke B, in which is cast the round hole m part way through the yoke B and the square hole 1 through the top part of yoke B.

Figure 7 shows-the yoke B cut in two, in order to show therelative position of the round hole m and the square hole n in the middle of yoke B.

Figures 8 and 9 are washers. v

Figure 10 is a gear-wheel, D, with a projecting socket, r, to fit on the projection T on top of the bell.

Figure 11 shows the gear-wheel D on fig. 10 out in two, in order to show the relative position of socket 1' with centre hole .9 through hub D.

Figure 12 shows the top of the hell, with a square projection, '1, to fit into socket r on gear-wheel D. In large bells this projection is made round, and in that casethe socket on gear-wheel D will be round also.

Figure 13 is the bolt 0 n that holds the bell to the yoke, and the clapper Y on this bolt 0 n is a square collar, 11., which is made to fit into the square hole n in middle of yoke B, and by this means prevent the clapper from turning round with the hell, and always keeping it at right angles with the bell.

Figure 14 is a perspective view of a bell mounted, with a ratchet motion fixed at the joint of the hammer, so that the action of the hammer in moving to and from the bell will cause the working pawl I to drop into a new tooth on the ratchet-wheel B at every motion of the hammer, thus causing the hammer to rotate round the outside of the bell. Y

Figure 15 is an end view, and

Figure 16 a side View, in order to show those parts that cannot be seen in fig. 14,

To enable others skilled in the artto make and use my invention, I- will now describeits construction and operation.

Letter A in fig. 1, sheet 1, is the bell, B the yoke, C the gear-wheel on top of the bell, d the worm or screwgear, 0 a small gear-wheel, F a small gear-wheel, g a large gear-wheel, H a large ratchct-wheeh-I a small gearwheel; J is the working pawl, 7c the cam or eccentric, m the lever, Zthe joint in which the cam-lever works; 11/ is a chain or cord fastened from the end of cam-lever m to the arm of the tollingdmmmcr a; P is the rope fastened in the end of arin of tolling-hammer and-conveyed down. to the bell-ringers room; q are the standards that bear the weight of the bell; R is the; clapper. The bell is first made with a projection or top, of'any desired form orshape, like fig. 12 on sheet 2. The gear-wheel D on fig. 10, sheet 2, then made, with a hole or socket on the under side to fit the projection T on top of the bell.- This wheel also has a projecting hub on top, D in fig. 11, that fits i nt'o the round hole in middle of yoke fig. 6, sheet 2. The bolt 0 n on fig. 13 is then put through the top of the bell T and the gear-wheel D, and the hub D" and the yoke B, until the square collar n comes into the square hole 11, in the middle of yoke B, as shown infigs. 6.and 7 on sheet 2. The nuts are then screwed on to the end of bolt on, and the bell is made fast to the yoke B. The worm or scrmv-wheel d and gear-wheel e are then put in the position as shown in figs. 1 and2 on sheet 1, so that the thread of wormwheel 0? will work into the gear-wheel C. The gear-wheels F g are then put into the yoke B, so that the'teeth of gear-wheel F will work into gear-wheel e. The ratchet-wheel H and gear-wheel I are then put into the yoke B, so that the teeth of gear-wheel I will work into the gear-wheel g. The cam in is then put into the-joint b on stand g. The working lever J and working pawl J are then put into theyoke B, and on the-same bolt with ratchet-wheel H, the end of lever J resting on cam is. The check-spring s is then put to work into ratchet wheel H. The tolling-hammer o is then put into the stand q, and the chain or rope n' is then attached from the iever' m of cam is to the arm of tolling-hammer 0. The rope P is then attached to arm of tollinghammer 0. .The bell is then mounted.

The operation is as follows: In swinging the bell to and fro, in order that the clapper R shall strike the side of the bell, the end of lever J moves up and down the eccentric cam thus giving to the working pawl J a motion up and down the ratchet-wheel H, so that as it goes down it falls into a fresh tooth in ratchet-wheel H, and as it goes up, it moves ratchet-wheel H one tooth forward, and check-spring s slipsinto ratchet-wheel H and holds it there. Thus, by the action of swinging the hell, it is made to rotate horizontally around its own centre. In cases where the bell is large, and where it is used daily for morning services, they do not swing the bell as. above described, but they use the tolling-hammer 0, which is applied to the bell mountings for that purpose; and in order that the bell shall be rotated horizontally around its own centre by the action of the tolling-hammer I have constructed the eccentric cam is, fig. 3, sheet 1, with the attached lever mAvorking .in joint 1, fig. 4, and have attached the lever m to the tolling-hammer 0 by chain or rope n, as shown in fig. 1, sheet 1, so that when the ringer pulls down on rope 1? he will also pull down the chain or rope 'n and thelever m, thereby lifting up cam is and working pawl J the distance of one tooth and moving the ratchet-wheel H, the check-spring s slips into ratchet-wheel H and keeps'it there. When the ringer lets the tolling-hammer 0 fall back to strike the second blow, the working pawl J moves into another tooth onratchet-wheiel H, and so, by the action of the tolling-hammer, the bell is made to rotate horizontally around its own centre. The addition of a single rope tied to the end of lever m or cam 70, and carried down to the bell-ringers room, will enable him to rotate the bell, independent of the action ofswinging the hell or of the use of the tolling-hammer, by giving to the said rope an up-and-down motion, causing the cam k to move up and down, thereby working the ratchet H, as before described. This is sometimes necessary when we remount old bells that have been in use a long time, and have been incessantly struck on two points until the'metal at those points has worn very thin and brittle, so'that a few blows more would break the bell. 'In this case the bell-ringer would use the extra rope and rotate the bell, without striking or sounding the bell until it had passed the point of danger. The lever J is forked, so that it embraces ratchet wheel H, and the end of each fork is connected with the bolt or axis of said ratchet-wheel H. The cam is is permanently secured .to lever m, so as -to partake of whatever motion is given to said lever m. The lower or under sideof said cam is hollowed out to form a socket, which fits a fixed pin or rest that projects from the inner face of standard 9. Said pin or rest is seen in the drawing in fig. 1, sheet 1, partly covered and concealed by the cam. When the lever m is in'its normal position, the cam it rests upon said pin so as to have a firm bearing thereon; and the said cam is held stationary and prevented from having any movement sideways, because the sides of-the cam project on each side of thepin. This arrangement enables me to use the said cam for rotating the hell by the swinging of the bell itself, the lever J, which carries pawl J", being above the axis on which the yoke B'turns, the swinging of the bell and yoke carrying the free end of lever J (whose end isprovide'd with an anti-frictionn'oller) to and fro over thetop of cam is, whereby said free end of that lever is lifted and the pawl J" is operated, as above explained. In rotating the bell through the swinging ofthe clapper, the lever in is vibrated and the cam Ic is brought up against the end of lever J, which is lifted so as to operate the pawl, the curve on the top of cam-1c being reduced or flattened at the point where the end of lever J or the anti-friction roller rests, so that the parts will'not roll or move away from each other.

What I claim as new, and desire to secure by Letters Patent,

1. The combination of the lever m and cam or eccentric 70, substantially as and for the purpose described.

2. Arranging a pin or rest beneath cam is to supportxit and give it a firm bearing, and also curving the inder side of the cam, substantially as described. I I

3. The combination and arrangement of the movable cam or eccentric-Ia with the pawl lever J, substantially as described.

4. The combination of the movable ohm or eccentric: k, lever m, and clapper a, substantially as described, for the purpose of rotating the bell.

5. The combination of the movable cam or eccentric k and pawl lever J with the gearing H. I, g, F, a, worm. d, and wheel 0, substantially as and for the purpose described 6. The arrangement in yoke B of square hole n in the centre of round hole' m, for the purpose of receiving the square part 10/, of bolt 0 11,, substantially as described.
