SPECIFICATION forming part of Letters Patent No. 641,033, dated January 9, 1900.

Application filed .Tune 26, 1899. Serial No. 721,911. (No model.)

To @ZZ whom it may concern:

Beit known that I, ISAAC E. PALMER, a citizen of the United States, and a'resident 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 certain improvements in ham mock-supports, one object being to provide a hammock-support in which the backbone or ridge-pole is made extensible and contractible, so that the said support may be conveniently packed for shipment and when set up for use may be extended to suit the wish of the occupant of the hammock supported by it.

A further Objectis to provide an effective means for rigidly clamping the legs of the support to the ends of the ridge-pole.

A still further object is to provide metallic brackets for the several parts, which may be clamped rigidly thereto without the use of bolts.

A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure lis a view of the support in end elevation as it appears when set up for use, the position of the legs when released from their clamping engagement with the ridge-pole for permitting the legs to be removed from the ridge-pole being shown in dotted lines. Fig. 2 is a view of the support in side elevation, the support being shown in an extended position in dotted lines. Fig. 3 is a partial top plan view of the support. Fig. 4t is an enlarged detail end view showing the manner of clamping the legs to the ridge-pole. Fig. 5 is a detail sectional view with the parts in the same position as in Fig. 4l. Fig. 6 is a view similar to Fig. 4., showing the position of the parts when the legs are swung away from each other for releasing them from engagement with the ridge-pole to permit the legs to be removed therefrom. Fig. '7 is a side view of the parts shown in Fig. 4:. Fig. S is an enlarged detail front View of the device for clamping one of the extensible sections of the ridgepole to the middle section. Fig. 9 is a transverse vertical section through the same. Fig. 10 is a transverse vertical sectional view through the middle section of the ridge-pole,

showing the bracket for rigidly spacing the side bars of the section apart. Fig. 1l is a top plan view of the same; and Fig. l2 is aview of the inner end of one of the extensible sections, showing the bracket for rigidly spacing the top and bottom bars apart.

The backbone or ridge-pole of the support is composed of a middle section a and two extensible end sections b and c. section a comprises two Y longitudinal side bars, which are rigidly spaced apart at a point about midway their lengths by a bracket d, which bracket has two vertical portions d d2,

,which extend along the inner sides of the side bars, top and bottom webs cl3 d4, which connect the vertical portions, and top and bottom extensions d5 d6 and which embrace the top and bottom edges of the side bars lay over their outer sides. The side bars of the middle section are rigidly secured together at all times only by the bracket ol. One of the said side bars is provided with a longitudinal central rib di', which extends inwardly along its inner side opposite to a similar rib d8, extending along the inner side of the other side bar.

Each of the extension end sections b and c consists of top and bottom longitudinal bars spaced apart at both ends, which bars are fitted to slide along within the middle section d of the support, the longitudinal ribs of the said middle section serving to guide the extensible section in its inward and outward movements. The inner ends of the longitudinal top and bottom bars of the extensible section are rigidly spaced apart by means of a bracket c. The bracket e is provided with a vertical web which extends inwardly, which web is adapted to be driven into the ends of the two bars. The bracket e is further provided with pairs of laterally-extended wings, which are iitted to embrace the top and'bottom edges of each of the bars, which wings are preferably caused to impinge the wood of the said bars, so as to hold them rigidly in position.

p The outer ends of the top and bottom bars of each of the extensible sections are rigidly spaced apart by means of a bracket f, which bracket has an inwardly-extended vertical web f', which is itted to be driven into the ends of the said bars. The bracket fis further provided with a pair of inwardly-ex- The middleA IDO tended branches f2 f 3, fitted to embrace the top bar, and a pair of branches f4 f5, iitted to embrace the bottom bar of the extensible section. The opposite edges of the several branches are preferably serrated to form teeth, which teeth are bent into the wood of the bars, so as to securely clamp the bracket in its position Without the use of bolts. The spacin g-bracket fis further provided between the upper and'lower branches with two pairs of seats ffl, one pair of seats- 6, for instance--being located at the outer end of the bracket and the other pair of seats f7 being located at the inner end of the said bracket. The bracket is further provided at the inner end of its lowermost branch f with a downwardly-extended lug g for preventing the su pporting-legs from being shoved too far in* wardly from the ridge-pole.

The means which I employ for clamping the extensible sections of the ridge-pole to the middle section in any desired longitudinal adjustment consist of fastening devices located Y port.

at the ends of the said middle section, each of which clamping devices is composed of the following parts: A clip h is secured to the outer side of one of the side bars of the middle section near its end and a second clip 'L' is secured to the outer side of the opposite side bar at a point opposite to the clip h. A screwbolt j passes through the clips h and el and the side bars, the head of the bolt being engaged with the outer face of the clip h, forinstance, and its screw-threaded end projecting beyond the outer face of the clip c'. The screw-threaded end of the said boltj is engaged by a clamping-nut k, which nut is preferably provided with an operating-handle, so as to permit a considerable purchase to be obtained by the operator upon the said nut for causing the nut to draw the side bars of the middle section snugly into engagement with the top and bottom bars of the extensible section when the nut is screwed home. As the nut 7c is unscrewed the extensible section will be released and may be slid longitudinally to the point desired, when it may be again clamped.

The ridge-pole is supported by four legs, arranged in pairs at its opposite ends. As the two pairs are alike, I will only describe the legs Z and m at one end of the sup- Each leg consists of a bar split from its upper end'a considerable portion of its length. The leg may be made of a single piece, or it may be made of separate pieces secured irmly together. A bracket n is provided with a pair of inwardly extended branches n n2, fitted to embrace one of the bifurcated ends of the leg Z, and another pair of branches n3 n4, arranged to embrace the other of the bifurcated ends of the leg l. A web a5 connects the branches n2 n3 of the said bracket. A bracket 0, quite similar to the bracket a, is provided with two pairs of branches o 02 o3 o, which are arranged to embrace the bifurcated ends of the leg m. This bracket o is also provided with a web o5 for connecting the branches o2 o3. The edges of the several branches of the brackets n and o are preferably serrated to form teeth, which are caused to impinge the wood of the supporting-legs, so as to rigidly secure the supporting-legs within the brackets without the use of bolts.

The brackets n and o are hinged to inner and outer collars p and q by hinge-pintles r and s, which collars are fitted to slide loosely over the end of the ridge-pole until they are stopped by the engagement of the collar p with the lug g, carried by the bracket f.'

The brackets n and 0 are provided with pairs of inwardly-extended shoes t and u, which are adapted to engage the seats in the bracket f and grip the collars p and qrigidly to the ridge-pole when the legs are drawn inwardly toward each other. When the legs are swung outwardly away from each other, the pairs of shoest and a are swung away from their engagement with the seats, and the collars p and q are thereby released, permitting the pair of legs to be removed from the rid ge-pole.

The leg-brackets n and o are provided on their branches n4 o4 with lugs a6 06, arranged to limit the outward-swinging movement of the legsl and m by their engagement with the collar q.

The pairs of legs are locked in their position nearest to each other for clamping the legs rigidly to the backbone by a link connection, which is composed of a pair of rods w w, hinged together, the rod w being hinged to a gripping device 0o, itted to slide along the leg Z, and the rod 1 0 being hinged to a gripping device iitted to slide along the leg m. As the gripping devices x and y are slid upwardly the legs Z and m may be swung away from each other, thus permitting the removal from and insertion of the legs onto the ridge-pole. This link connection w w will permit the legs to be folded closely together when not in use.

One of the collars, in the present instance the collar q, is provided with a suitable hook z for the attachment thereto of one end of a hammock.

The support as above constructed is very simple and strong, is composed of a very few parts, is quickly adjustable, and readily set up or taken down.

The several metallic parts hereinbefore described may be made of some malleable metal, so as to permit them to be firmly secured in their respective places.

This construction enables me to do away entirely with the use of bolts for clamping the several parts of the woodwork of the support together.

While I have described my improvement as a hammock-support, it is obvious that the structure may be used as a su pport for a chair or swing, if so desired.

What I claim is- 1. The combination with a ridge-pole, of
