ROBERT C. DANLY, 'OF CHICAGO, ILLINOIS, ASSIGNOR TO LUDWIG 8c LUDWIG, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

DRUM AND CYMBAL BEATER.

Specification of Letters Patent.

Patented Aug. 9, 1921.

Application filed December 8, 1919. Serial No. 343,234.

Be it known that I, ROBERT C. DANLY, a citizen of the United States of America,

and a resident of Chicago, in the county of I Cook, State of Illinois, have invented certain new and useful Improvements in Drum and CymbalBeaters, of which the following is a specification.

This invention relates to that class of combined drum and cymbal beater mechanisms which are adapted for operation by the foot of the player, and more especially to the type of such mechanism forming the subject matter of Letters Patent to William F. Ludwig, No. 922706, dated May 29, 1909, and No.'1,092,276 dated April 7 1914,and thepresent improvement has for its various ob'ects:

0 provide a structural formation and as sociation of parts in a striking mechanism adapted to attain a rapid and unimpeded initial travel of the hammer head with a gradually increasing resilient resistance to further travel of the head and by means of which a sharp blow of the hammer and a rapid initial return of the same is at tained with a minimum effort on the part of the player.

To provide a simple and efficient structural formation and arrangement of the cymbal beater or striker, whereby the same is capable of effective adjustment to the right or to the left side of the mechanism, as well as to an intermediate inactive or dormant position, as may be required by the player.

To provide a simple and durable formation of the carrying rail or shank of the cymbal beater adapted to afford the proper degree of resiliency to the same, and which at the same time affords an effective ele ment in the means for fastening the cymbal striker in its active and inactive positions above referred to.

To rovide a simple and effective structural ormationof parts whereby the felt or fibrous hammer head of the drum heater is secured in an effective manner to its carrying stem, and a very desirable rigidity imparted to the peripheral portion of said head, all as will hereinafter more fully appear. In the accompanying drawing Figure 1, is a front elevation of a mechanism involving the present invention.

Fig. 2, is a side elevation of the same. Fig. 3, is a detail sebtional elevation on line 33, Fig. 2, of the cymbal beater and its carrying arm.

Fig. l, is a detail elevation of the cymbal beater arm.

Fig. 5, is a detail front elevation illustrating the different positions to which the cymbal beater is adjusted and held.

Fig. 6, is an enlarged detail elevation, partly in section of the hammer and its op erating mechanism.

Like reference numerals parts in the several views.

Referring to the drawing, 1 designates a portion of the drum head or membrane, and 2, the usual hoop by which said head or membrane is held in a tensioned condition on the main body or shellof the drum. 3 designates the stationary frame or standard of the mechanism, having an expanded bottom or floor base and detach ably secured at one end to the aforesaid hoop 2 by a rocking or clamping bar 4 and operating screw 5 as shown, or by any other ordinary fastening means.

6 designates a floor bar or rail detachably connected at one end to the base of the standard 3, preferably by means of the operating screw 5 aforesaid, and provided at its other end. with a pivot head for the attachment of the operating pedal 7 of the mechanism.

8 designates a rock sleeve or hub journaled at the upper end of the standard 3 and having arms 8 and 8 arranged in angular relation to each other to form a bell-crank,

indicate like with the arm 8 attached to the free end-- the other arm 8 is connected to a tension spring 10 that is connected in an adjustable manner to the standard 3, as shown in Figs. 1, 2 and 6. The sleeve or hub 8 is provided with a lateral split sleeve 11 adapted to receive in a longitudinally adjustable manner the carrying stem 12 of the drum beating hammer head 13, the parts being held to the required adjustment by a side clamping bolt passing through bracket ears at the sides of the slit of the sleeve 11, as usual in such type of split sleeve fastening means.

A material part of the present invention involves the positioning of the arms 8' 8" of the rock sleeve or hub 8 in relation to the point of attachment of the spring 10 to the upright or standard 3, with the free end of the arm 8", which is connected to the spring 10, in a vertical plane a distance inside a. vertical plane passing through the aforesaid point of fixed attachment of the aforesaid spring. With such arrangement, the weight of the hammer head 18 is adapted to impose a pulling stress on the spring 10 when such hammer head is in its down or inactive position shown in full line in Figs. 1 and 6. Such stress in the manual actuation of the appliance will aid materially in reducing the force required to impartinitial movement to the hammer in its active stroke in that said hammer will acquire initial velocity before the spring 10 is brought into action to interpose a resilient resistance to the final travel of the hammer. In consequence the initial effort on the part of the player is materially reduced and a more rapid stroke of the hammer head is attained.

Another part of the present invention involves means for attaching the beater head or body 13, when the same is formed of felt or like fibrous material, to the carrying stem 12 aforesaid, and comprises a detail construction as follows l4: designates a reduced outer portion of the stem 12 providing an abutment shoulder at its point of junction with the main portion of the stem 12 as illustrated in Fig. 6.

15 and 16 designate centrally orificed concavo-convex washers or plates fitting the reduced portion 1a of the stem 12, wit-h the inner washer 16 bearing against the above described abutment shoulder, while the outer washer 15 is preferably held in place by upsetting or riveting the outer end of the reduced stem portion, 1 1 against said washer.

In the described construction the beater head or body 13 is disposed between the washers 15, 16, with the holding stress thereof exerted at their peripheries, so that the stress will be near the periphery of the head or body 13 to hold the felted material thereof in a rigid condition adjacent to its striking or impact perimeter, with the result that a very effective and durable hammer head is provided.

17 designates a bracket piece or head secured to the beater stem 12 by a clamping screw 18 in an adjustable manner along said stem. Said bracket piece is provided with a lateral bearing face or rim 19 formed with pairs of radial recesses 20, in right angle relation to each other as shown in Figs. 3 and 5.

21 designates the cymbal beater head fixedly secured to one end of a carrying bar or rail 22, which in the preferred form of the present invention is formed of astrip of resilient metal of the curved form shown and having its attaching end formed as follows 23 designates a return bend portion at the attaching end of the rail 22 and preferably of the rounded loop form shown in Fig. 3. In the present construction the rail 22 and return bend portion 23 are formed with alined orifices for the passage of the screw 18 aforesaid, and also with ridges or projections 2a in adjacent relation to said orifices, and res ectively adapted for yieldingly holding engagements in the aforesaid radial recesses 20. and for bearing engagement against the flat under face of the head of the clamping screw 18, as shown in Figs. 8, and 5. With the described construction a very effective holding of the cymbal beater arrying bar 252 at any of the positions illustrated in full and dotted lines in Fig. 5, and at the same time a very durable structure is provided.

Having thus fully described my said invention what I claim as new and desire to secure by Letters Patent, is 2- 1. In a drum and cymbal beating mechanism, a beater head of fibrous material, a carrying stem, a pair of concave-convex holding washers engaging opposite sides of said heater head, and means for fixedly attaching said washers to said stem.

2. In a drum and cymbal beating mechanism, a beater head of fibrous material, a carrying stem, a pair of concave-convex holding washers engaging opposite sides of said beater head, and means for fixedly attaching said washers to said stem, the same consisting of a shouldered outer portion on said stem, and an upset outer end on said outer portion.

3. In a drum and cymbal beater mechanism, a drum beater head, a carrying stem, a bracket lug secured to said stem and having a bearing rim formed with holding recesses disposed in circularly spaced relation to each other, an arm pivotably connected to said bracket lug and having a cymbal beater head at its outer end, and resilient means associated with said arm and adapted to force the arm into holding engagements in the aforesaid holding recesses.

4. In a drum and cymbal beater mechanism, a drum beater head. a carrying stem. a bracket piece secured to said stem and having a bearing rim formed with holding recesses disposed in circularly spaced relation to each other. a resilient arm pivotably connected to said bracket lug and having a cymbal beater head at its free end, and a resilient return bend portion at its attaching end adapted to force the arm into holding engagement with the aforesaid holding recesses.

53. In a drum and cymbal beater mechanism of the type described. a cymbal beater arm formed of resilient material and having a long member and a short member integrally connected in parallel relation by a return bend. said members having alined orifices for the passage of an attaching screw and the long member having a bearing ridge at the margin of its orifice.

6. In a drum beater mechanism, a supporting standard, a rock sleeve pivoted on said standard and provided with angularly disposed arms, a beater carried by said sleeve, a foot pedal pivotally associated with said standard, a link connecting said pedal to one of said arms, and a spring attached at one end to said standard and at the other end to the other of said arms, the connecting point of said spring and arm lying normally in a vertical plane inside of the vertical plane passing through the connecting point of the spring and standard, and so that in the commencement of the strike movement of the beater'the spring will assist in such movement and in the ending of such movement will act to retard the same.

Signed at Chicago, Illinois, this 24th day of November, 1919.

ROBERT C. DANLY.
