' NITED STATES PATENT OFFIcE.
MAX G'ANTER, OF BUFFALO, NEW YORK, ASSIGNOR TO EUGENE DE KLEIST,
OF NORTH TONAWANDA, NEW YORK.
SPECIFICATION forming part of Letters Patent No. 596,108, dated December 28, 1897.
Application filed March 20, 1 8 9 '7.
To all whom, it may concern.-
Be it known that I, MAX GANTER, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Swings, of which the following is'a specification.
This invention relates more particularly to portable indoor swings designed to be suspended between a pair of uprights, such as the jamb or sides ofa doorway.
The object of my invention is the production of an inexpensive supporting device for such a swing which can be readily and reliably secured in place without the use of nails, screws, glue, or other fastenings that mar or mutilate the door-jamb.
In the accompanying drawings, Figure l is an elevation, partly in section, showing my improved supporting device in position across a doorway, with a swing hung therefrom. Fig. 2 is a fragmentary vertical longitudinal section of the device on an enlarged scale. Fig. 3 is a fragmentary top plan View thereof on an enlarged scale. Fig. 4 is a horizontal section in line 4 4:, Fig. 2.
Like letters of reference refer to like parts in the several figures.
A A represent a pair of uprights between which the swing B is suspended and which may be the sides or jamb of a door-frame, as shown in the drawings.
0 is a horizontal supporting-pole from which the swing is suspended and which is provided at each end with a pair of wedges D E, whereby the pole is clamped between the jamb or uprights A. The inner wedges D are rigidly secured to the. ends of the pole, so as to carry the pole, while the outer wedges E bear loosely with their vertical rear faces against the door-jamb and with their inclined front faces against the reversely-inclined faces of the inner wedges D. The inner wedges are free to slide vertically on the outer wedges, so that a downward pull on the pole causes the inner wedges to force the outer wedges against the jamb, thereby tightly clamping the pole between the sides of the doorway and reliably holding it in place without the use of nails, screws, or other fastenings which disfigure the jamb. By this construction the Serial No. 628,550. [No model.)
pole is secured more tightly the greater the weight suspended from the pole.
The outer wedges are preferably permanently attached to the inner wedges, so as to keep the parts of the device intact and facilitate the application of the device to a suitable support. For this purpose the wedges at the same end of the pole are connected bya screw or bolt f, passing through a vertical slot f, formed in the outer wedge and through the inner wedge and entering the end of the pole, as shown in Figs. 2 and 4, the slotted wedge being recessed on its back, as shown at f to countersink the head of the connecting-bolt. In order to increase the friction between the jamb and the outer wedges E, the latter are provided at their back with a facing g of canvas or similar rough material. This facing also serves to cover the recess and slot of the wedge. To keep the wedges of each pair in their proper relative position, one of the wedges is provided with one or more vertical tenons h and the other is formed in its opposing face with grooves h for receiving these tenons, thereby preventing the wedges from turning or twisting on each other.
The pole may be made in a single continuous piece, if desired; but it is preferably made of two adjustable sections, as shown in Fig. 1, so that it can be lengthened or shortened to fit different-sized doorways. In the construction shown in the drawings the polesections areconnected by a sleeve or tube I, in which they are adj ustably clamped by setscrews In order to relieve these screws when the sections are partly drawn out, the vacant space in the sleeve between the inner ends of the pole-sections is filled by cylindrical blocks j. By the use of these fillingblocks the pole is rendered practically continuous and the thrust is received by the end wedges instead of the set-screws.
The pole is provided with hooks or other suitable attachments 7a, with which the rings Z of the suspension-cords Zof the swing are engaged, as shown in Fig. 1.
In applying the pole to a doorway the outer wedges E are slid downwardly on the inner wedges to the limit of their movement, and the pole is then adjusted in length so that the outer wedges touch the door-jamb. The
outer wedges are then driven upward with a mallet, and the pole is at the same time held with one hand and gently pulled downward, the pole being securely clamped in place by the time that the wedges are tightened. The wedges should be located about two inches below the lintel or top of the doorway after the wedges have been tightened. After securing the pole in position the swing is suspended therefrom. In order to remove the pole, it is only necessary to press the same upward vigorously, when the wedges will be loosened.
Myimprovement is not only extremely simple, but can be quickly applied and released without inutilating the part to which it is attached,renderin g the device especially advantageous for indoor use.
I claim as my invention 1. A support for portable swings, consisting of a pole, inner wedges secured to opposite ends of the pole, outer wedges bearing with their inner faces against the inner wedges, and adapted to bear with their outer faces against a pair of uprights, and connections between said wedges which permit the outer wedges to slide on the inner wedges, substantially as set forth.
2. A support for portable swings, consisting of outer wedges adapted to bear against a pair of uprights, and a pole provided at opposite ends with wedges which bear against said outer wedges, the wedges at the same end of the pole being provided with an engaging tenon and groove whereby the same are retained in alinelnent with each other, substantially as set forth.
A support for portable swings, consisting of a pole provided at opposite ends with inner wedges, outer wedges bearing against said inner wedges and each provided in its front face with a vertical slot and in its rear side with a recess opening into said slot, screws or bolts passing through the slotted wedges and entering the inner wedges, each of the outer wedges having 011 its rear side a facing which covers the slot and recess thereof, substantially as set forth.
4. A support for portable swings, consisting of a pole composed of adjustable sections each provided at its outer end with a pair of cooperating wedges, a sleeve connecting the inner portions of the po1e-sections, and fillingblocks arranged in said sleeve between the adjacent ends of the pole-sections, substantially as set forth.
W'itness my hand this 16th day of March, 1897.
