UNITED STATES PATENT orrncE.
CFCIL H. STRUPE, 0F INDIANAPOLIS, INDIANA, ASSIGNOR TO LEEDY MANUFACTUR- ING COMPANY, oF INDIANAPOLIS, INDIANA, A
CORPORATION OF INDIANA.
TYMPANO.
To all whom z't 'mm concern.'
e it known tat I, CEoIL H. STRUPE, a citizen ofthe United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented new and useful Tympanos, of which the following is a specification.
The object of my invention is to produce a tympano which can be readily and acpitch, the construction being such that it may be readily disassembled for transportation without dismemberment of the primary hand controlled tuning members from the head ring, thereby retaining the primary operative condition of the head upon the kettle.
The accompanying drawings illustrate my invention: F ig. l is a vertical section of an apparatus embodying invention; Fig. 2, a fragmentary sectional detail, on' a scale Somewhat larger than that of Fig. 1, of one of the tuning units; Fig. 3, alfragmentary detail, in partial vertical section on a plane at right angles to the plane of Fig. 2, of parts of one of the tuning elements; Fig. 4, an` elevation in partial vertical section of the connection between the foot pedal and main pull` rod; Fig. 5, a detail in partial vertical section of a modification of the connection between the foot pedal and main pull rod; Fig. 6, a section in line 6-6 of Fig. 5, this being equally illustrative of the same parts shown in Fig.
1; Fig. 7, a section on line 7 7 of Fig. 5: Fig. 8, a plan on line 8-8 of Fig. 7 and Fig. 9, a section on line 9 9 ofFig. 4.
In the drawings, 10 indicatesy the kettle. of ordinary form, provided at itsupper end with the usual ring l1 upon which the vi bratinghead 12 is supported. j
The head 12 is provided with the usual fiesh ring 13 which, in turn, is engaged by the horizontal flange of the usual pressure ring 14., said pressure ring being provided at suitable circumferentially spaced points with eyes 15 which, at their upper ends, form a support for the pressure washer 16 engaged 'by the adjusting nut 17 on the tuning pin 18, the threaded shank ofvwhich is projected upwardly through the eye 15 and washer 1G into nut/17. The lower end of the tuning pin 18 kis provided with a spherical head 19 which seatsin asemispherical socket 20 secured to the shell of the kettle 10, suitable internal bracing rings 21 being provided to afford adequate support for the brackets.
Up to this point the construction is well known.
The socket. 2O is so formed that head 19 may be freely moved downwardly away from its seat in the socket 20 and, in the present construction, this movement is accomplished by means of a link 22 and bell crank v23 the bell crank being conveniently formed of a pair of sheet metal stampings, as clearly shown in Fig. 3, pivoted at 24 to the bracket 20 in whichL socket 20 is formed.
vBetween thel elements which form bell crank 23, I pivot a block 23 having a diametrical threaded perforation into which is threaded the outer end of a pull rod 25.
The several pull rods 25 are projected inwardly, through suitable perforations 26 in kettle 10, and their inner ends are joined by a central head 27 which is j ournaled upon the upper end of the primary pull rod 28, which, at itslower end, is threaded, at 29, into a block 30, the primary pull rod being projected through a perforation 31 in the Y bottom of the kettle. I The kettle 10 seats in a conical cup 35, the wall of which is perforated at diametrically opposite points, as indicated at 3G, so that the operator may readily reach a collar 37, secured to the pull rod 28, in order that said pull rod may be screwed into or out of the block 30.
Pivoted upon bolt is a. toot lever Fit) preferably formed ot a pair ot mating sheet metal stampings and an intermediate cross head 51.
Between the straddled legs of lever 50 is a ratchet segment 52 secured to the fitting 3S as shown in Fig. 5, and adapted to be engaged by a plurality of pawls 53 pivoted on the cross rod 54 of the pedal lever 50, said pawls being of varying lengths with a variation substantially equal to one step ot ratchet 52, so that lever 50 may be held in minutely variable positions. Pivoted at adjacent the heels of pawls is a plate 56y normally held in the position shown in Fig. 4 by spring 5T against the stop 5S, but so proportioned that, by a pull exerted on rod 59, the plate may be brought into engagement with the pawls 53 in order to litt them from engagement with ratchet The pull rod 59 is projected through a per- `toration 60 in plate 56 so as to be readily rotatable and its opposite end is threaded and projected through a diametrical threaded perforation in a block G2 (dotted lines Fig. 5) pivotally supported in a treadle or toot piece G3 pivoted at 64 upon the outer end of lever 50, the arrangement being such that a nice adjustment oi. the parts may be obtained so that a comparatively small swing of' the toot piece 63 upon lever 50 will serve to retract the pawls 53 from the teeth of segment Up to this point., the constructions shown in detail in Figures 4 and 5 are identical. It will be readily understood that the precise connect-ion between block 30 and lever 50 may be varied to a considerable extent without departing trom the spirit ot my invention as thus tar disclosed, and that such variations may in themselves possess distinguishing characteristics.
It is, ot course, desirable that, as the pitch o't the instrument is increased by greater tensioning oiE the head 12, the resistance oiliered by said head to movement of the toot lever be as nearly uniform as possible, as such a. condition facilitates the accurate tuning of the instrument. For this reason, I prefer the form of connection shown in Figure 4, where the lower end ot block 3() carries atrunnion head 70 provided at its ends with trunnions 71 journaled in the outer ends of a pair of links 72, 72, pivoted at 73 to segment 52, said trunnions T1, 'Tl also serving as the pivotal connection with the upper ends of a pair ot links 74, T4 pivoted at to toot lever 50. In the initial position, i. e.. with the foot lever 50 at its highest point yand the head 12, theretore, in such condition as to give the lowest pitch sound, the links 74 lic at a very acute angle to links 72 but, as lever 5() is depressed, the angle between the links T 2 and 74 gradually increases, thus causing the torce applied to links 74 to act with a gradually increasing leverage upon links T2 and consequently to act. with a gradually increasing leverage upon block 30 and the primary pull rod 2S and thereby compensar;- ing the gradually increasing resistant-e et head 12.
Referring now to Figures 5 and T, it will be noted that links 72 are omitted; that links T4 (corresponding to links 74 in the other form) are directly pivotally connected with head 3() and that head 3() is slidably mounted in a guide way St) in segment In this construction links T4 approach the line Ot' movement of block Bt) in. guide St) as the foot, lever is depressed and there is some slight increase in leverage, as a consequence, but, owing to the particular limitations in proportion which are involved from structural necessities, this increase in leverage is not quite so great as it is in the other form.
It will be noted that, by unser-owing the rod 28 from block 30, the. kettle l() may be lifted from cup 35 but that the initial tuning of the instrument will not be moditied because the tuning pins will have their heads 19 remain seated in the sockets 20. It will also be noted, that in reseating the kettle 10 in cup and forming the connection by screwing the rod 28 into block 30, the kettle may be seated in the cup with a very substantial pressure because, until the tension set up in rod 2S is equal to the. tension of the initial tuning set up in the timing pins, the heads 19 ot the tuning pins will remain seated in sockets 2O and there will be no modiication in the pitch ot the instrument due to the initial tension in the head 1.2. It is, therefore, apparent that the instrumentmay be readily dismembered for transportation without such separation ot the parts as to cause inconvenience or require complete retuning.
It is also apparent that, because o't'i the tiXed abutments (sockets 20) which are provided for the tuningpins, the central head 2T may be placed deep down in the kettle and the pull rods 25 extended ata considerable angle down into the kettle, because the connection between the head 2T and toot pedal is not depended upon in obtaining the initial tensioning ot the skin '12 Then the parts are separated for transportation, rods 25 are not under tension.
