TRIPOD FOR HAIVIMOCK-SUPPORTS.

SPECIFICATION forming part of Letters Patent No. 769,913, dated September 13, 1904.

Application filed March 28, 1904.

To all whom it 777/6111] concern:

Be it known that LVVILLIAM J. NOBLE, a citizen of the United States of America, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Tripods for Hammock-Supports and the Like, of which the following is a description.

My invention belongs to the class of portable supports for hammocks and for kindred purposes, and has for its object the production of a simple, economical, and effective device for the purpose described.

To this'end my invention consists in the novel construction, arrangement, and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts, Figure 1 is a side elevation of my invention with a hammock in position. Fig. 2 is a partial section on line 2 2 of Fig. 3. Fig. 3 is a partial section on line 3 3 of Fig. 2, and Fig. 4: is a detail view of the binding-ring.

In the preferred form shown in the drawings, 1 is a suitable head provided with laterally-extending lugs 2 for the pivotal connection of the legs 3 3 3 to the head. As shown, the lugs are arranged in pairs, and the legs are pivotally connected thereto by a pin or bolt extending through the pair of lugs and the leg, as at 4. The legs are each provided with a tapered end 5, extending beyond the pivotal support, which when the legs are extended in proper position is adapted to lie close to and contact with the head 1, as shown in section in Fig. 2. A ring 6 is loosely mount' ed on the head 1 in such a manner as to provide a longitudinal movement thereon and is formed to embrace the tapered ends of the several legs when in position and firmly bind them against the head, as shown in Fig. 2. This serves to so lock the legs in operative position that the tripods may be readily moved from one position to another without disarranging the relative position of the parts.

To prevent accidental disengagement of the several parts, I prefer to provide ,means for Serial No. 200,251. (No model.)

locking the ring in operative position. For this purpose I provide the ring 6 with one or more cam-faces 7 in the upper part, which contact with a pin 8, carried by the head, and thus positively lock the ring or sleeve in position upon the ends 5 of the legs.

To disengage the lock, it is only necessary to longitudinally move the ring upward to release the ends 5 of the legs, which may then be compactly folded together for packing or transportation. In the form shown the ring is given a reverse turn to release the cams from the pin for this purpose, when the ring may be lifted, as described. When the legs are folded, the ring 6 may readily drop down and be, positioned between the ends 5 and the head 1, tending to retain the parts in their folded position. In the preferred form of ring (shown in Fig. 4) the extreme run of the cam is provided with a straight face 9 to prevent any accidental reversal of the cam and a slight upward extension 10 to limit its operation and prevent its accidental release by turning the cam too far as the parts become loose or worn from use or otherwise.

In the general use of my support two tripods are used, connected bya bar 11 or equivalent means. Any suitable means may be employed to connect the ends of the bar with the tripods. In the preferred form the head is provided with an upwardly-extending pin 12 and the end of the bar with a suitable aperture 13 to receive the pin for this purpose.

The downward pull of the hammock will ordinarily be suflicient to prevent the accidental disengagement of the bar and head. To aid in the assurance of suitable engagement in use, I prefer to employ some adequate means to lock the parts together. As shown, a bar or strut 14 is firmly clamped at one end to one of the legs, as at 15, and extends across to the next leg, having its other end forked or curved to loosely receive the latter, as at 16. Astrap or band 17 is secured to the bar 14 and extends upward to a point opposite an extension 18 on the end of the bar 11, (see Fig. 2,) and engages said extension. As shown, an aperture 19 is formed in the end of the band 17 to receive the end 18 of the bar 11, as shown in Fig. 2. The band 17 has sufficient spring to enable the parts to be connected or disconnected, as described. I also prefer to form an eye 20 on the ends of the bar 11 or provide equivalent means to secure the hammock in position. It is obvious that, if preferred, the several legs, as well as the bar 11, may be sectional to secure compactness in packing or transporting the device. As shown, the parts are so constructed, the several parts being composed of steel piping with the joints clearly shown at 21 on the legs and at 22 on the bar 11.

As an independent improvement well adapted for cooperative use with my improved supports I show an awning-support, which is, however, not limited in its use to my peculiar supports. As shown, the bar or strut 14 carries an additional bar 23, which extends up ward to'a point above the bar 11 and terminates in means for the engagement therewith of a stretcher 24, supporting one end of a horizontal awning 25. Any suitable means may be employed to engage the stretcher 24 with the end of the bar 23. As shown, the free end of the bar 23 is flat and is provided with a horizontal extension 26, which is positioned in a correspondingly-slotted piece 27, carried by the stretcher 24. By this means the draw of the awning will cramp the piece 27 on the extension 26, and the spring of the bar 23, supported from its lower end, will tend to keep the parts in proper engagement. If desired, a spring 28 may be provided on the extension 26 to prevent accidental disengagement of the parts. The lower end of the bar 23 is pivotally engaged with the strut 14, aifording means for swinging the bar on its pivotal support to adjust the awning to the varying angle of the suns rays. A thumbnut 29 is provided for the pivot-bolt 30 to control the adjustment of the awning. It will be seen that the bar 23 is pivoted at a point removed from the horizontal plane of bar 11, which permits the awning to be so adjusted as to afford the same protection to the occupant of the hammock at all times. It is also obvious that the length of the arm 23 and the strap 17, as well as the location of the strut 14, may be varied as desired in constructing my device.

It is obvious that after thus describing my improvement various immaterial modifications may be made without departing from the spirit of my invention. Hence I do not wish to be limited to the exact form and construction shown.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent,- is

1. A tripod for hammocksupports and the like, comprisinga head, and legs pivotally connected to the head and provided with tapered ends adapted when the legs are extended to lie closeto the head, in combination with a ring longitudinally movable on the head'and adapted to embrace and bind the tapered ends of the legs to the head, said ring being provided with cam-faces cooperating with a fixed part on the head, whereby upon turning the ring it will be forced downward upon said tapered ends.

2. In a device of the kind described, a pair of tripods each comprising a head provided with an upwardly-extending pin 12, legs pivotally connected to the head and provided with tapered ends adapted when the legs are extended to lie close to the head, in combination with a ring longitudinally movable on the head and adapted to embrace and bind the tapered ends of the legs to the head, a connecting-bar 11, provided with an extension 18, and having apertures near its ends for the reception of the pins 12 on the heads, and a bar 17 for each tripod secured to the legs thereof and having its upper end apertured to receive the pin 18.

3. In a device of the kind described, ahead provided with an upwardly-extending pin 12,
