Specification of Letters Patent.
Patented Nov. 13, 1906.
Application filed August 28. 1905. Serial No. 276,163.
To all whom, it wbag concern:
Be it known that 1, ROBERT L. HAMMOND, a citizen of the United States, residing at 'Woodsboro, in the county of Frederick and State of Maryland, have invented certainnew and useful Improvements in Horn-Supports; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in'the art to which it appertains to make and use the same.
My invention relates to improvements in horn-supports or cranes for talking-machines of all kinds.
The object of the invention is to provide a simple and convenient device of this charac ter which is universally adjustable, so that it may be quickly and easily applied to the bod y-box of any talking-machine and its parts adjusted to hold a horn of any size in the proper position.
A further object of the invention is to improve and simplify the construction and operation of devices of this character, and thereby render the same more efficient and durable in use and less expensive to manufacture.
With the above and other objects in view the invention consists of certain novel construction, combination, and arrangement of devices hereinafter described and claimed.
In the accompanying drawings, Figure 1 is a view showing the application of the support or crane to the body-box of a talking machine, said box being indicated in dotted lines. Fig. 2 is a vertical sectionalview on an enlarged scale through the device. Fig. 3 is a perspective view of the clamping device for the pivoted-horn-supporting arm. Fig. 4 is a detail sectional view taken on the plane indicated by the line 4 4 in Fig. 3. Fig. 5 is a detail sectional view taken on the plane indicated by the line 5 5 in Fig. 2. Fig. 6 is a detail perspective view of a slightly-modified form of base, and Fig. 7 is a bottom plan view of the brace-bar.
Referring more particularly to the drawings, the numeral 1 denotes my improved horn support or crane, which is adapted to be attached to the body-box A of atalkingmachine of any description. The device 1 comprises a base 2, consisting of a flanged plate 3, a leg or foot 4, an upright tubular holder 5, and a clamp 6. The clamp 6 is adapted to engage the under side of the bottom or base ofthe body-box A and is preferably adjustably secured to one end of the plate 3 by means of a screw 7, which is carried by the clamp 6 and passes through an opening 8, formed in the plate 3, and is adapted to receive a clamping-nut 9, as clearly shown in Fig. 2 of the drawings. The clamp 6 is in the form ofa strip or plate of metal which has at one end an enlargement 10, bent or offset angularly, as shown at 11, so as to overhang and engage the molding upon the bottom of the body-box A. 'The opposite reduced end 12 of the clamp 6 is formed with a longitudinal slot 13 and its under face,
' adjacent to said slot, is grooved or recessed longitudinally, as shown at 14 in Fig. 5 of the drawings. Upon said end 12 of the clamp is adjustably mounted a slidable clamping j awplate 15, which is adapted to engage the molding upon the body-box A, as shown in Fig. 1 of the drawings. This aw slides upon the top of the clamp and has its inner end bent upwardly and inwardly to engage said molding. The main portion of the jawplate may be slightly bowed, as shown, and is formed with an aperture 16 to receive a clamping bolt 17. The latter projects through the slot 13 and the aperture 16 and has a polygonal-shaped head 18, which slides in the grooves 14 in the clamp. Upon the upper end of the screw 17 is provided a clamping-nut 19, which is adapted to bind the parts together to secure the aw-plate 15 in any adjusted position. By providing the angu ar or ofiset portion 11 of the clamp and the adjustable jaw-plate '15 it will be seen that the device may be clamped upon the bases or bases and bodies of talking-machines of any size and make.
Instead of em loying the clamp 6 (shown in Figs. 1, 2, an 5 of the drawings) I may use the attaching means 20. (Shown in Fig. 6 of the drawings.) This attaching means is very similar to the one just described, the only difierence being the omission of the jawplate 15 and the reduced end 12 of the clamp and the provision of screw or bolt holes 21 in the enlarged portion 10 of the clamp. It
will be seen that when this fastening means is employed screw-bolts or the like are passed through the openings 21 and the bottom orbase of the box A.
If desired, the device may befurther connected to the body-box A by means of a brace-bar 22. The latter is in the form of a plate or strip of metal, which is apertured at one end, as shown at 23, to receive a tubular v bers or sections31 and 32, the former being the latter, as shown in Fig. 7 of the drawings. A clamping-screw 22 passes through an opening in the arm and the slot in the plate 22 and has its threaded end engaged with a threaded opening in a cam-plate 22 which is disposed between the flanges 22 and adapted to frictionally engage them to hold the sliding plate 22 in an adjusted position against the outer face of the side wall -of' the body-box A, as seen in Fig. 1 of the drawings. This brace-arm 22 may be readily applied and removed, so that it may be used or omitted,-as desired.
The upright holder 5 is tubular in form and has an enlarged base 26, which rests thereto by a series of screws 27, which are "passed upwardly through the leg or foot 4,
upon" the plate 3 at one end and is secured the plate 3, and into screw threaded recesses in said base 26, as shown in Fig, 2 of the drawings. If desired, these parts maybe cast or molded in one piece. The base 26 and the leg or foot 4 are preferably ornamene tal, the latter, as shown, being in the form of a claw, which is adapted to rest upon the table or other support upon which the talking-machine is placed. U on the upper end of the upright tubular hol er 5 is an annular;
enlargement or collar 28, which is formed at the'side or directly'in front with a screwthreaded opening to receive a clamping screw 29. The latter has a finger-piece at its outer end and at its inner end i's'adapted to engage the standard 24, which telescopes within the holder 5, and which is vertically adjustable therein by means of said screw 29.
The upright 24 is preferably tubular'in form and has adjustably pivoted upon its upper end an extensible horn-sup orting arm 30. This arm 30 swings vertica ly-and consists of inner and outer telescoping mem- "solid and the latter being tubular, so as to telescope over the same. The inner section 31 has at its inner 'end an enlargement 33,
the like 34 to the center of an enlargement of "head 35, provided upon the upper end of the which is pivotally connectedby a rivet or standard 24. This enlargement or head 35' "is in the form 'of'a disk, which is beveled or wedge-shaped from one side 36, which is connected to the standard 24 to its diametrically opposite side 37. This circular plate or disk isformed in one-half with a substantially semicircular slot 38, which is arranged concentrically with the pivot34, and is'adapted -a screw-eye '43.
to receive a clamping-screw 39, which is carried by the head or enlargement 33 upon the arm 30. This screw 39 has a rounded head to engage a concaved washer 46, which bears against the inclined face of the wedge-shaped disk 35, and its threaded end passes through the slot 38 and into the threaded opening formed in the enlargement 33, as clearly shown in Fig. 4 of the drawings.
It will be seen that by providing the slot 38 and the screw 39 the arm 30' may be-adjusted in an angular position with respect to the upright 24, and that owing to the taper or wedge shape of the disk 35 these parts will be clamped more firmly as the arm 30 is swung downwardly, the gradually-increasing thickness of said disk serving as a-we'dge, which works betweenthe washer and the inner face of the enlargement 33, as will be readily seen upon reference to Figs. 1 "and 3 of the drawings. The outer section 32 of the arm 30 slides upon the section 31 and may be adjustably secured at any desired point thereon by means of'a set-screw 40,*-which passes through the threaded opening" formed in an annular enlargement or collar 41, provided upon the inner end of the section 32. The section 32 is of less length than the section 31 and has its outer end open, as shown, so that it may be reversed upon the section 31 to permit very small horns to be supported. U on said outer end is provided an annular en argement or collar42, in which is secured To said screw-eyeis connected a short chain 44, upon the end of-which is a hook 45, adapted to enga e an attaching device upon the horn of the ta kingunachine.
The construction, use, and advantages of the inventionwill 'be readily understood by reference to'the accompanying drawin s.
It will be seen that the device may be applied to talking-machines of any description, and that its arts may be quickly and easily adjusted to irmly support any size -horn in any desired position.
Owing to the connection. of the device to the bottom of the bOClY bOX A the weightpf the latter will hold the support inan upright position, and there will be no liability ofthe machine overturning even-when theleg or foot4 isnot resting upon the table or other support. By means ofthe set-screw 29' the arm 30 and its standard 24 maybe swung or adjusted angularly in-ahorizontal plane, by means of said set-screw the standard 24 may be also adjusted-vertically; by means of the set-screw 39 the arm 30 may be adjusted-angularly in a vertical plane, and by means of the set-screw 40 thelength' of the armmay be'adjusted according to the size of the horn.
Having thus described my invention; what I claim as new, and desire to secure by Letters Patent, -is
1. A horn-support having astandard provided witha headhaving vertical sides'which converge in one direction, a horn-suppor ting arm pivoted to said head, a clamping-screw engaging a threaded opening in said arm and having a head, and a washer between and irictionally engaging the standard-head and the clamping screw-head, said screw-head and washer having curved ooengaging surfaces adaptingthe washer for angular motion on the screw-head, substantially as described.
2. A horn-support having afoot member, a plate projecting therefrom, a clamp'for attachment to'the body of a talking-machine and detachably secured to the late, a tubular upright holder projecting om the foot member, a standard vertically adjustable in the said holder, and a horn-supporting arm carried by the standard, substantially as described.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
