HORN-CRANE.

Specification of Letters Patent.

Patented Dec. 21, 1909.

Application filed May 28, 1906. Serial No. 319,040.

To all whom "it may concern:

Be it known that I, JOHN H. B. CoNonR, of the city of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Horn-Cranes, of which the following is a specification.

The invention relates more particularly to those cranes or supports for amplifying horns which are adapted to be held in position by extending beneath the cabinet of a talking machine and being clamped thereto, and the objects of the invention are to secure improved means of clamping the basepiece to the cabinet; to retain adjustability of such clamping means, while concealing the adjusting means; to thus secure a neat and finished construction; to secure an improved connection of the horizontal arm and post. of the crane, and one which will permit of ready adjustment or even of entire separation of said parts for packing or the like; to provide a simple construction, and to obtain other advantages and results, some of which may be referred to in the following description.

Referring to the accompanying drawings, in which like numerals of reference indicate corresponding parts in each of the several figures, Figure 1 is a side elevation of my improved horn crane applied to a talking machine cabinet; Fig. 2 is a plan of the lower portion of the crane, and Fig. 3 is a section on line at, Fig. 2; Fig. 4 is an elevation, partly in section, of the post and arm of my improved horn crane; Fig. is a rear view of the connection between said arm and post, and Fig. 6 shows in side view the curved end of the said arm which enters into such connection; Figs. 7 and 8 show in part section and in rear elevation respectively, another method of connecting the arm and post; and Fig. 9 illustrates a detail of the arm.

In said drawings, 1 indicates a talking machine cabinet to which the lower part 2 of my improved horn stand or crane is attached. To effect this attachment, said lower part comprises a strap-like piece of metal 3, adapted to extend underneath the box, as shown in Fig. 1, and project at both ends. One of said ends is bent up so as to form a clamp or clutch 1, to engage the bottom molding 5 of the cabinet 1, and the other end of said strap 3 is secured in a shallow recess 7 at the under side of a casting 8, which forms the main part of the support, preferably by means of countersunk screws 9, 9. Above the said strap 3 the top of the recess 7, is provided with a shallow and preferably narrower chamber 10, in which the foot 11 of an adjustable clamp member 12 is freely slidable, said foot having a slot 13 to receive the screws 9, 9, as guides. The head 14 of the clamp member 12, projects upwardly from said foot 11, at its end next the cabinet and is adapted to grip over the molding thereof, in cooperation with the hook 1, at the opposite end of the strap 3, as will be understood. In order to slide the said clamp 12 back and forth, a screw 15, works through the base-piece S, from its front, the inner end of said screw preferably being inclined downward and engaging the head 1 1 of the clamp 12. Obviously this engagement might be a simple abutting of the end of the screw against the head of the clamp, the clamp being retracted by hand, but I have shown in the drawings a construction by which the said screw carries the clamp with it in both directions. To this end the extremity of the screw lies in a groove 16 of the clamp-head 1st and is provided with an annular recess 17. A pin 10 is then driven downwardly through the head 1-1 of the clamp so as to lie in the said recess 17 of the screw and prevent. withdrawal of the screw out. of the groove 16, while at the same time not interfering with its rotation.

The casting S of the base-piece of my improved construction covers the clamp-member 12 and end of the strap 3, and projects outward from the talking machine cabinet, as at 18, to secure a long stable bearing. At its opposite end, or end next the cabinet, there is a hood-like extension 19 which overreaches the clamp member 12 and end of the screw 15, so that the same are practically hidden, as will be understood by referring to Fig. 8 of the drawings more particularly. Said casting S has at its top an upward extension 20 which provides a tubular socket 21 adapted to receive the lower end of the post of the crane or horn support, said post being preferably a cylindrical rod of any desired length. A set screw 23 working through the side of the socket 21 enables the post to be clamped against withdrawal.

The standard or post is at its upper end preferably provided with a top or enlargement 24 which is shown in the drawing as being of an ovoid shape. This enlarged end 24: of the post has a curved hole or passage 25 extending through itself from a point at or near its top downward and out at one side, and in which passage is arranged the correspondingly curved end 26 of the horn-carrying arm 27, which is adapted to project forward in horizontal or inclined position and support from its extremity the horn, as is common in the art and accordingly not shown in the drawings. This curved end 26 of the arm is preferably solid and is squared, as is also the passage 25, so as to prevent movement except in a vertical plane. The said end 26 lies downward or beneath the main portion of the arm, so that it is introduced into the passage 25 from the top of the same. To hold the parts in locked or clamped position, one side of the curved end-piece is provided with sockets or seats 28 to receive the end of a set screw 29, workin through the side of the enlargement 24:. r any other suitable clamp means known to the art may be employed if desired, such for instance as shown in Figs. 7 and 8, where the convex lower end of the bent piece 261 is provided with notches 30 to receive a set screw 31 working through the back of the enlargement 241 into the passage 251.

The horizontal arm 27 is preferably in sections which can be adjusted longitudinally, the outer section 32 being shown as a solid rod and the other section 33 a piece of tubing which receives at its outer end 34 the said section 32 and has a set screw 35 therefor, the inner end of the tube section 33 having the curved end-piece 26 inserted therein and firmly secured in place.

By the construction thus described, the arm 27 can be adjusted up or down in a vertical plane and set at any desired point, while the post 22 can be turned to secure horizontal adjustment of the arm. At the same time the said parts are firm and rigid, and by the lower part 2 are secured to the talking machine cabinet without bringing any strain thereon or causing danger of upsetting the same.

Having thus described the invention, what I claim is:
