BASS DRUM BEATER Filed Nov. 27, 1936 2 Sheets-Sheet 2 Patented Oct. 4, 1938 UNITED STATES PATENT OFFICE 7 Claims.

This invention relates to a bass drum beater. More particularly, this invention relates to certain improvements in mechanism for effecting a quick return of the beater ball and in the construction of the pedal.

Bass drum beaters have been heretofore provided with a beater ball adapted to be returned by a spring or the like connected to a beater ball bracket and fastened adjacent a supporting post in exposed relation. I have found that locating the spring in this manner is an annoyance, not only in the operation of the foot board, but also in the handling of the device. The spring should not be located in a position to permit accidental engagement by the foot during operation of the foot board, nor should it be located so that it will interfere with the folding of the device or the handling thereof during transportation.

Accordingly, I have devised improved means for overcoming these disadvantages by incorporating this spring in a structure which is not only simple and inexpensive to construct, but which provides a more efficient arrangement of parts and a more rapid return of the beater ball.

One of the objects of the invention is to incorporate this return spring in the supporting posts in concealed relation and to devise an improved type of connection between the spring and rock shaft carrying the beater ball so as to effect a rapid movement of the beater ball when the foot board is actuated.

Another object of the invention is to accomplish these results by a simple and inexpensive structure.

It is also the purpose of the present invention to provide an improved form of foot board that is capable of conversion from a single-piece foot board into a two-piece foot board having separately movable heel and toe portions.

It is found that many individuals prefer a single-piece foot board permitting the entire foot to rest upon and actuate the foot board. On the other hand, many individuals prefer to move only the upper-part or toe portion of the foot when actuating the foot board and prefer to rest the heel and use it as a pivot point in the movement of the foot. Accordingly, I have devised an improved form of foot board which may be formed into a single-piece foot board or a two-piece foot board. No tools or implements are required to make the change. The change in form may be quickly made so that the foot board may be converted from one type to the other at will.

Other objects and advantages of the invention will be apparent from the following detailed description when taken in connection with the accompanying drawings which form a part hereof.

In the drawings:

Fig. 5 is a perspective view of the foot board, illustrating it as a single-piece structure; Fig. 6 is a similar view, but illustrating the foot board converted into a two-piece structure; and Fig. 7 illustrates the device folded and ready for transportation.

A bass drum beater embodying the present in- 20 vention comprises a base I, supporting posts 2 and 3, a rock shaft 4, a beater ball 5, a foot board 6, and a flexible connection 'I between foot board 6 and beater ball 5. A clamping jaw 8 is pivotally carried at 9 upon base I, for holding the device to 25 a rim such as IU of a bass drum II. Rim I0 of drum I I is gripped between jaw 8 and one or more feet I2 extending outwardly from base I, a locking screw I3 being provided to hold clamp 8 in locked position against drum rim I0. 30

Foot board 6 is pivotally mounted at I4 upon an extensible bracket I5 secured at I6 to base I.

A pair of spaced lugs Il and I8 at the upper end of foot board 6 receive a pin I9, to which the lower end of leaf spring 1 is hooked. The upper 35 end of leaf spring I is hooked to a pin 2| carried by a pair of lugs 22 and 23 formed on a bracket 24 secured to rock shaft 4 by means of a lock pin 25. Bracket 24 is enlarged at 26 and provided with two openings 21 and 28 toreceive stern 29 of 40 beater ball 5. Openings 21 and 28 intersect each other as illustrated in section in Fig. 2. At the point of intersection a lock screw 30 is provided so that it will engage and lock the lower end of beater ball stem 29, whether it is inserted in open- 45 ing 21 or opening 28. The purposes of a plurality of openings 2l and 28 for receiving beater ball stem 29 is well understood in the art. Different occasions require different striking distances for the beater ball. These openings 21 and 28 provide 50 such an adjustment.

Beater ball 5 will swing forwardly to strike the diaphragm of drum II when foot board 6 is depressed. Leaf spring I acts as a flexible connection between pedal 6 and beater ball bracket 55 upper end of supporting posts 2 and 3.

In order to effect a quick return of beater ball 5 away from the diaphragm of drum Il and a quick but smooth return of foot board 6 to its original position after it is depressed, so that it will be ready for another operation as quickly as possible, one or both supporting posts 2 and 3 may be cored so as to receive mechanism that effects said quick return of the beater ball and the foot board. This mechanism is extremely simple and is entirely concealed within one or both supporting posts 2 and 3. The mechanism comprises a spring 35 and a rod 36. Rod 36 is preferably cut at 31 so as to allow sufficient room for a roller bearing 38 carrying the end of rock shaft 4. Rock shaft 4 is provided with an eccentric pin 39 adapted to engage the upper end of rod 36. Spring 35 is preferably an expansion spring and is adjustable at the bottom of the post by a pin 4U.

The upper end of each post is preferably cored out into a circular opening as indicated at 4| if said posts are made in the form of castings. The opening 4l permits easy assembly of the ends of rock shaft 0l in the upper ends of posts 2 and 3.

VBearing 33 may be inserted upon its seat as indicated at 42 and the end of rock shaftrll inserted. Rod 36 may then be inserted into the post from the lower end until its reduced portion 43 engages against eccentric pin 39. Spring 35 is then inserted in the post.

Pin 46 may be held in place by a screw plug lil. Collar 'H will rest upon plug I6. Theupper part ofpin 40 is threaded so that a nut l2 may travel therealong to adjust the tension of spring 35. Spring 35 will bear upon nut 12 sufiiciently to cause it to travel along the threaded part of pin 40 when it is turned at its slotted end 13.

It will be observed that the parts described are few and simple and that they are devised to be assembled in a very simple manner.

When foot board 6 is depressed, eccentric pin 39 is brought to bear against the upper end of the reduced portion 43 of spring rod 36. This action depresses spring rod 36 against spring 35. When foot board 6 is released, spring 35 immediately raises rod 36 to lift eccentric pin 39 up so as to translate the lineal movement of rod 36 into rotary movement at rock shaft 4. The action of the spring is instantaneous and vreturns not only the beater ball 5 away from the diaphragm of drum Il, but also returns foot board 6. Foot v Y board 6 is made smoothly to follow the movement of the foot so that it may be in a position to be depressed instantly whenever desired.

One of the advantages of locating the mechanism for effecting the return of beater ball 5 and foot board 6 will be noted in Fig. 7 which shows the drum beater in folded position ready for transportation. It is essential that a device of this type be readily folded. YMusicians are called upon to transport their instruments from one place to another, and it is essential therefore that not only should the-device be easily folded in a compact manner, but also it should have its parts constructed to permit easy handling after the device is folded. herein the spring mechanism is concealed. It is impossible, therefore, to destroy the spring accidentally in handling the device in folded position during transportation, or for the spring to be a constant source o'f'annoyance by reason of being exposed and in the way of the drummer. It will be understood that each post 2 and 3 In the device disclosed 24. Shaft 4 will be rocked in its bearings in the may be provided with the mechanism described without complicating the exterior design of the device in any Way. If this mechanism is provided in each post, the movement of the foot board 6 and beater ball 5 will be extremely smooth and quick, and will be well balanced.`

The further advantage resides in the fact that if one of the springs breaks, the spring in the opposite post will be sufficient to operate the device. On the other hand, the device may be operated satisfactorily if the return mechanism above described is provided in one of the posts-only.

To permit Vfoot board 6 to be readily converted into a two-piece pedal which many individuals desire in lieu of the single-piece foot board, I have constructed the heel portion 56 in separate relation to the upper or toe portion 5l. This latter portion 5l is provided with a pair of spaced lugs 52 and 53 which extend rearwardly to hinge upon pin I4. One side of heel portion 50 is provided asa flat face 55 to allowrthe heel to rest flatly thereupon with flat-face 55 exposed. As illustrated in Figs. l and 5, the pedal is adapted to be used as a single-piece foot board. Heel portion 56 is secured to the toe portion 5l by means of a screw 56 disposed underneath the toe portion 5l and carried Yin a lug 5l formed thereon. The under side of heel portion 56- 'that is to say, the side opposite to the face 55- is enlarged at 58 and is adapted to receive the end of screw 56 so as to lock heel portion 50 to the toe portion 5l with flat face 55 coextensive with the ilat'surface of toe portion 5I.

However, enlarged portion 58 is a part of the design of the side of heel portion 56 opposite to face 55, that permits the heel of a shoe to readily restV thereupon while theV upper or toe portion of the foot engages part 5l of foot board 6 to operate the same about pivot E4. By referring to Fig. 6 it will be observedV that enlarged portion 58 is provided with a gentle downward curve as indicated at 59, there being a further depressed face 56' lying between the spaced lugs 52 and 53 vas illustrated in Fig.V 6.

The heel is adapted to rest upon enlarged por- Y tion 58. The upper part or toe portion of the foot is adapted to rest upon the toe portion 5I of foot board 6. The heel part 56 will engage at 6l upon the door and keep the same from pivoting about pin I4 while toe portion 5i is depressed.

Enlarged portion 58' of the heel 56 is provided with a relatively large flat face 62 that ts somewhat closely to face 63 on toe portion-5I between spaced lugs 52 and 53. The close fit between these faces permits the heel portion 50 to be rotated from the position shown in Fig. 6 about pin i4 to the position shown in Fig. 5. The close fit of these faces 62 and 63 allows heel portion 55 to snap into position and remain in this position for normal use. If, however, it is desirable to lock heel portion 56 to the toe portion 5l, locking screw -56 may be employed.

It will be apparent that the pedal construction above described may have a wide application, and I do not intend, therefore, to limit the same to bass drum beaters. The construction has an advantage of providing a single-piece or a twopiece pedal at will, without additional expense or complicated design of pedal.

Without further elaboration, the foregoing will so fully explain the gist ofy my invention that others, by applying current knowledge, may readily adopt the same for use under varying conditions of service vwithout eliminating certain features which may properly be said to constitute the essential items of novelty involved, which items are intended to be defined and secured to me by the following claims.
