earsa'r orrics O13 CHICAGO, ILLINOIS COMBINATION CHIN BEST AND SHOULDER PAD Application filed June 27,

This invention relates to a combination chin rest and shoulder pad for attachment to a violin and has for its primary object to provide in a manner as hereinafter set forth, a device of the class above mentioned, wherein the chin rest and shoulder pad are formed from molds taken directly from the jaw and collar bone res ectively;

A further object of the invention is to pro-- vide a chin rest and shoulder pad as aforesaid, including as a part thereof, means for adjustably clamping the chin rest and shoulder pad portions together, and for further clamping the same to a violin through the medium of the hole which is formed in violins for accommodation of the tail piece button.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the drawings in which like numerals are employedto designate likeparts throughout the same,

Figure 1 is a fragmentary plan view of a violin showing an embodiment of my invention secured thereto,

Figure 2 is an end elevation of the same,

Figure 3 is a section taken on line 8 3 of Figure 1,

Figure 1 is a section taken on line 4L4.- of Figure 3,

Figure 5 is a section taken on line 55 of Figure 3, showing the shoulder pad in fragmentary plan,

Figure 6 is a perspective detail view of the chin rest. i

In the drawings wherein for the purpose of illustration is shown-an embodiment of my in yen-Zion, the numeral 1 designates a violin, including the usual block 2 at one end thereof, said end and block being formed with a bore 3 for the accommodation of the usual tail piece button, not shown. I prefer to use the bore 3 for securing my attachment'in position, and for this purpose a clamp nut 1 is substituted for the customary tailpiece button.

The chin rest 5 according to my invention, consists of a vertical portion 6 and an angularly ofiset, horizontally extending portion 7. The vertically extending portion 6 is formed with a transverse groove 8, which divides the 1928. Serial No. 288,697.

portion 6 into a pair of legs 9 for seating on the upper face of the violin. The groove 8 is adapted to receive therethrough the tail piece of the violin not shown.- The horizontally extending portion 7 is formed with

tapered ends

10 and 11 respectively and is provided in the face thereof with a diagonally extending depression 12. That portion of the chin rest 5. which extends between the depression 12 and the end 11 is elevated above the remaining surface of the chin rest and forms a raised roll 13 substantially triangular in contour. The chin rest 5 is formed from a mold taken directly from the human 1' aw, and in applied position, the depression 12 receives therein the jaw bone of the user and the roll 13 fits within the hollow behind and underneath the jaw bone. i

The shoulder pad l l is of elongated formation and has its rearward edge 15 slightly convened and its forward edge 16 slightly concaved. One end 17 of the shoulder pad 14 is of substantially greater thickness than the opposite end 18, and the rearward edge 15 is of substantially greater thickness than the forward edge 16. The lower surface 19 of the shoulder pad 14: is formed in a manner to conform to the configuration of the human collar bone. The shoulder pad 1 1 is of slightly less length than the length of the chin rest 5 and in assembled relation the end 17 of the shoulder pad 14: projects outwardly from the end 11 of the chin rest 5.

Secured to the upper face of the shoulder pad 1 1, by means of suitable holdfast devices 20, is a clamping member 21, which is formed with a reduced extension 22 which is bent upwardly and returned parallel to the horizontal plane of the main portion of the member and spaced therefrom. Adapted for en gagement with the extension 22 is a pair of spaced bars designated by the

numerals

23 and 12 1 respectively. In assembled relation the bar 23 seats beneath the extension 22 and thebar 2% seats above said extension. relative thickness between the bars 23 and the space between the extension 22 and member 21, and the relative thickness of the e2:- tension 22 to the space between the bars 23 and 24: provides for a snug fit when the several The v members are in assembled relation. The rearward edges of the bars 23 and 2a are in alignment with the rear edge of the violin, and extending rearwardly :om the bar 24 s a pair of arms which terminate in vertial portions 26, which extend in parallel re- .ation to the end of the violin and are spaced therefrom. The portions 26 are formed with external left hand threads for a purpose to be hereinafter disclosed.

The rearward faces of the legs 9 of the chin rest are formed. with a. pair of bores 27, into which a pair of arms 28 are threaded. 'ihe arms 28 terminate in vertically extending portions"; 29, which are disposed in oppr ing relation to the portions 26, and are med with external right-hand threads.

"or The

portions

29 and 26 are connected together by means of a pair of internally ihreaifled cylindrical couplings 3(.

For securing the chin rest and shoulder pad to the violin, 1 provide a pin 31 which is adapted to be inserted into the bore 3 of the lolocl; 2. T he inner end of the pin 31. is ormed with a long u linal slot 32, between th opposing walls of which is pivoted a tilt key 33. The point of pivotal connection a for the tilt hey located between the transverse median of the tilt lrey and one end thereof. Due to its increased length, the end 2-35 of the tilt key 33 is heavier than the end 236 so that the key 33 will normally swing about its pivot to assume a vertical position. Preferably the end is thicker than the en d ill to further increase the weight of the end 35. The pin 31 is formed with a rearwardly extending, reduced, externally tl'n'eaded extension 37, which projects rearwardly from the end of the violin when the tilt key 33 is [)Uhll'lOIlQtl to lie flat against the inner face of the block 2. I

Connecting the couplings 3() 1s a concaved plate 38, each end of which is formedwith a pair of curved lingers he inner surfaces of which conform in contour to the outer sur faces of the couplings 30. The plate is formed with a centrally disposed perforation it) to receive therethrough a collar ll formed on the inner end of the clamp nut l. The collar all is formed with internal threads for erunurement wi h the external threads of the *Fl ciision 37 of the pin 31. tearwardly of the collar ll, the clamp l is formed with an annular shoulder 4-2, the inner face of which uhuts against the outer face of the plate 38.

V hen the clamp nut l is rotated to tighten the connection between the collar 41 and the extension 37, the plate 38 is drawn towards the end of the violin by the action of the shoulder on the pi r and of the tilt key 33 on the inner end of the block 2. Pref erably a. groove or indentation 43 is formed in the inner face of the block 2 to assist in olding the tilt key 33 against rotation when clamp nut l is rotated to tighten the con nection. The extreme end 44 of the clamp nut -l: is enlarged to equal the diameter of the shoulder 42, thereby providing a neck portion 45 of reduced circumference.

To assen'ible my improved chin rest anlv shoulder pad and to secure the same to a :lin, the

arms

25 and 28 are respectively connected with the shoulder pad 14 and chin rest 5. The

portions

26 and 29 of the

arms

25 and 28 are loosely connected together by means of the couplings 30. The plate 258 is then positioned relative to the couplings 30, the collar ll of the clamp nut 4 is inserted through the perforations 40 and loosely threaded Onto the extension 37 of the pin 31. The smaller end 36 of the tilt key is then positioned within the slot 32 and the pin 31 is inserted into the bore As soon as the end 36 clears the wall of the bore 3, the abnormal weight of the end 35 of the tilt key 33 automatically swings the tilt key to a verti -al position. The pin is then withdrawn until the tilt key 33 lies flat against the inner surface of the lock 2 and the clamp nut i is rotated to tighten the connection between the collar l1 and the extension 37. After the a'ttaclnnent has thus been secured to the violin, the chin rest 5 and shoulder pad let respectively may be drawn into frictional contact with the upper and lower surfaces of the violin by rotating the couplings 80. The couplings 30 are provided with tool receiving apertures 46 for this purpose.

It is to be understood that the form of my invention herewith shown and described is to be talten as the preferred example of the same and that various changes in the size, shape and arrangement of parts may be resorted to *ithout departing from the spirit of the invention or the scope of the appended claim.
