Description
To all whom 'it may concern: .i Bl? tknowfn that.. we, MAcAniUs Maxi- MILIA'N' KSTNER" and CONRADl Ka'rz, sub- 'ects of' the German Empire, residing at ondon, England, have invented 'a new and :useful Pneumatic Striker Apparatus, of which the following is a' specification.
This inventionrelates to an improvement in neumatic musical instruments.
rdinarily the pneumatics at present :employed inmusical instruments, particularly the striking pneumatics comprise a rigid movable leaf which is hinged at one end so that the cross section of one of `these pneumatics is always triangular or substantially so; It is obvious of course that a triangle virtually requires as' much space as a recytangle formed on its base and ,of the 'same Athe same size as those employed for manuheight as the highest angle of the triangle. "Consequently these pneumatics take up wice-as much space as is really necessary in act. l Theprincipal object of this invention is to provide simple and inexpensive means .wherebyi apneumatic may be employed to occupyvery little more ythan the space which it theoretically ought to occupy 1n order to `secure the'desired result; that is, substantially. half the space required by a triangular Pneumatic ofthe same capacity and power. In view of the fact that one of the eatest problems to be solved in the manuacture of interior players is the construc- `tion of the 4parts so that they can be contained in an instrumentcasing which is of ally o erated instruments, it will be seen that t e reduction by half of the space re- 'quired foreach o'f-thestriking pneumatics i is an'important feature in this art.
trac eatin therewith, a series of pouches 4, the- FurtherV objects and advantages of the invention will appear hereinafter. Reference is to be had to the accompany` 'indrawings in which-- igure 1 is a rear view of a portion of a Section of .striking pneumaticsand their connected abstractsconstructed in accord- Lance with this invention, and Fi 2 is a transverse vertical sectional view tiereof. The invention is illustrated as applied to a t peV of musical instrument'having a lier 2, a series of channels 3 communipositlon Vof .which is controlled by the pres `ence of air in the correspondin channels 3, andan exhaust chamber 5.- Eac pouch con- ;vlj 4 l i; mi 1 n 4.` ,SpecimenLeers-fea anatema i Application tiled'November 20,` 19092 Seria-l No.l 529,127; i 'f `le'aves'a port 8 opentothjeV til er trolls a valve 'whicli y'normaliV tlon shown in'Fig. ini-fw l M port I7 connected witlfth ainberftiit' sa communicate -through "a striking pneumatic 10. of ai'r passes through" oneot' in the usual Way it operates the correspondmg pouch 4 to close the opening 8 and causes the valve to open the port 7 which connects the passage 9 with the exhaust chamber 5. All these parts of the apparatus oper ate in a Well-known Way.
The striking pneumatic is shown as comprising a-movable member 13 and a st ationary member 14. This movable member or leaf is designed to move bodily transi ersely with respect to its broad surface instead of having the usual swinging movement about a hinge. It is connected rigidly wi th its Vproper abstract 15 so that the two mcve together as by a screw or pin 16 secured to the abstract and fixed to the leaf 1'15. In order that this abstract, may be cau sed to move` along parallel lines it is provided at` its opposite ends with two links 17 pivoted to it. These links are pivoted at their opposite ends to stationary parts of the frame and are of equal length between the pivots. The pivots on the frame are at the same distance apart as the pivots on the abstract so that when the pneumatic causes tfie ab-` stract to move the latter'will always have aparallel motion and will take the abstract exactly with it. The abstract is shown as having a block 20 by which the blow is transmitted to the playing devices. By the use of this principle it will be seen that'substantially th e entire space between the supports 18 on which the pneumatics are located is occupied by the pneumatics themselves instead of only half the space as is the case with the. ordinary forms on the market. Consequently the space required for this entire set cl" striking pneu naties can be reduced almost Onehalf, thus permitting the use of pneumatic playing devices in piano cases where ,they could notA heretofore be used without enlarging the same.
lVhile we have illustrated and described a preferred embodiment of the invention, we are aware that" many Amodifications can be made therein by any erson skilled in the art-without departing rom the scope of the invention as expressed in the claims. There- 'combination of a pneumatic havin fore we do not wish to be limited to all the getails of construction shown and described, ut
