HAMMOCK-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 522,720, dated July 10, 1894:.

f Application filed September 16, 1893- Serial No. 485,681. (No model.)

To a whom it may concern:

Be it known that I, ISAAC E. PALMER, of Middletown, in the county of Middlesex and State of Connecticut, have invented a new and useful Improvement in Hammock-Supports, of which the following is a specification.

My invention relates to an improvement in hammock supports in which two pairs of legs, one pair at each end of a central ridge pole, are removably connected with the ridge pole and the ridge pole itself separable-into sections whereby the support may be quickly set up in a secure manner for suspending a hammock or may be folded up in compact form for shipment.

A practical embodiment of my invention is represented in. the accompanying drawings,

in which Figure 1 is a view of the support in side elevation set up as in use. Fig. 2 is an end View. Figs. 3 and 4 represent an end and side view respectively upon an enlarged scale of the groove and tongue plates for removably interlocking the adjacent ends of the ridge pole, and Fig. 5 represents an enlarged view in detail of one of the hooks at the top of a leg and its corresponding eye-piece on single piece of material, or it might be formed of two separate pieces bolted together. In either event I find it desirable to insert a staybolt 0, through the bar A from side to side at a point in proximity to the point where the sections a anda' begin to diverge.

The ridge pole is divided, preferably at its middle point, into two sections B and B and each of thesesections is split from the end at the center of the pole toward the ends of the support into upper and lower branches, the branches of the former being denoted by b and b and the branches of the latter by b and b Eachridge pole section like the legs, may either be formed of'asingle piece of material or it may be formed of two longitudinal half sections secured together near the ends of the support. The adjacent ends of the branches of the ridge pole sections are held the proper distance apart by means of sockets c extending in opposite directions from the interlocking groove and tongue plates 0 and O.

The ends of the branches 1), Z) are adaptedto enter the sockets projecting from the rear of the plate 0 and the ends of the sections 11 from the tongue plate G. It is intended that the ends of the said sections of the ridge pole shall be permanently fixed in. their sockets so that the plates will beheld to their respective ridge pole sections and at the same.

time the parts of the ridge pole sections will be held spread apart in a position to form an eifective brace.

The groove and tongue plates 0, C are each formed in two half sections, the plane of separation extending about midway through the upper and lower sockets c longitudinally of the sockets or in the direction of the length of the pole. The groove plate 0 is provided at its top portion with a short groove 0 in the arc of a circle and with a longer groove 0 at its bottom, also arranged in the arc of a circle, the grooves being preferably formed in laterally extended branches at the front of the plate. The groove plate C is further provided with a central socket c in its face for the reception of a corresponding lug on the opposite plate.

The sections of the groove plate 0 are drawn together to clamp the branches of the ridge pole in its sockets by means of a laterally extending bolt 0 extending through the webs of the sections to the rear of its face. The opposite or tongue plate 0 is separated into two sections in the same manner as the plate 0 just described, and the sections are held in assembled adjustment by a bolt 0 through their webs. The tongue plate 0 is provided at its top with a laterally projecting tongue 0 adapted to enter the groove 0' in the plate 0 and at its lower portion it is b are adapted to enter the sockets extending provided with a pair of laterally projecting tongues adapted to enter the the bottom of the plate 0.

The plates are adjusted, the one to the other by entering the central stud on the plate 0 into the socketat the central portion of the plate 0 with one of the parts turneda quarter of a revolution, more or less, to the right or left and the plate O with its ridge pole branches fixed therein is then ready to slide the tongues at the top and bottom into their respective grooves in the opposite plate by a rotary movement of the one relative to the other. The plates are locked in adjusted position by means of a latch c pivoted to the top of the plate 0 and adapted to swing down through a groove at the top of said plate and into a notch 0 formed in the tongue at the top of the plate 0'.

The ends of the branches may be conveniently locked in their sockets by casting interior projecting fins 0 in the half sockets and providing corresponding lateral cuts in the ends of the branches to receive the fins as the half sockets are adjusted to the branches.

The ends of the ridge pole are fitted to enter bands D which serve as ferrules for the ends of the pole. The bands D have upon their opposite sides and fixed thereto or formed integral therewith projecting ears d through which slots d are formed for the reception of hooks on the tops of the leg sections. The said hooks on the tops of the leg sections are denoted by E and have a recess on their sides toward the adjacent section of the leg, which recesses are adapted to receive a portion of the car 01 adjacent to the end of the slot 61' into them when they are adjusted for use to lock the legs to the ridge pole. The brace section of the branch a of the leg is provided with a hook atits upper end quite similar to that on the section a, with its recess facing in the opposite direction and it is adapted to enter a slot in an car on a second band D spaced fromthe first or end band D.

The hooks E are provided with heels 6 which, when the hooks have been entered through the slots d and the pair of legs at the end brought toward one another into position for use, bear against the opposite lower portions of the band D or the opposite lower portions of the ridge pole adjacent to the band and are thereby prevented from any tendency to approach each other further than such limit.

The legs forming a pair are held together near their lower ends by a tie-rod F. The tie-rod F consists preferably of a flat strip of material, hinged or pivoted at one of its ends to one of the legs of the pair and at its opposite end provided With a perforation f through which a locking pin may be inserted to hold it in position.

The tie-rod F may have its free end insorted between the diverging branches at, a of the leg, and notches or abutments f havgroove 0 at with the ends of the ridge ing their, abrupt faces downward may be employed to prevent the end of the brace from working up, the pin through the end'of the brace being adapted to engage the abrupt faces of said notches or abutments.

The end bands D may be conveniently provided with ,hooks d for retaining the hammock ring.

To set the supportup, first interlock the adjacent ends of the ridge pole as above set forth. The leg may then be engaged with the bands D, D by throwing the legs ofi to one side sufficiently far to permit the ends of the hooksE at their upper ends to enter the slots 01 in the ears (1. The legs may then be brought to the proper position and locked in such position by adjusting the free end of the tie-rod F with its pin in engagement with the notches or abutments on the leg. The structure when set up and a hammock suspended from the hooks at the opposite ends effective work, although they be made slender and light.

The taking apart for packing may be done by reversing the steps above set forth and either the setting up or taking apart will require but very short time and may be done by anyone, Whether skilled or not, without any liability of making a blunder.

What I claim is I 1. The hammock support, comprising a ridge pole and two pairs of legs, each pair of legs having a removable engagement with an end of the ridge pole, the several legs being spread apart at their upper ends forming branches one of which extends toward the end of the ridge pole and the other toward the ridge pole at a distance from the end, to form both supports and braces and means for connecting the members of each pair of legs when adjusted, substantially as set forth.

2. The hammock support, comprising a.

ridge pole composed of separable sections, and legs having a removable engagement with the ends of the ridge pole, the upper portions of the legs being divided and adapted to be spread apart to engage the ridge pole at different points of its length, substantially as set forth.

' 3. The hammock support, comprising a sectional ridge pole the adjacent ends of the sections being separated longitudinally and having fitted thereto groove and tongue plates for locking the ends of the structures together in separable adjustment, and supporting legs having a removable connection pole, substantially as set forth.

4E. The combination with the sections of the ridge pole, of a groove plate secured to the end of one section and a tongue plate secured to the end of the other section, said groove and tongue plates being formed in half sections and means for fastening the two plates in interlocked adjustment, substantially as set forth.

5. The hammock support comprising a horizontallyextending ridge pole having leg attaching bands at its ends, the bands being provided with slotted ears, and supporting legs having hooked upper ends, the points of the hooked ends being adapted to enter the slotted ears on the bands and the heels of the hooked ends being adapted to bear against the lower opposite sides of the ridge pole or bands, substantiallyas set forth.

6. The hammock support, comprising a ridge pole having leg attaching bands secured at its ends and at intervals from its ends, the bands being provided with slotted ears, and legs having their upper ends separated longitudinally and provided with hooks adapted to enter the slotted ears in both the end band and the band at an interval therefrom, sub- ISAAC E; PALMER.
