EXTENSIBLE BRACKET.

To all whom it may concern.'

Be it known that I, CHARLES, B. ConBiN, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Extensible Brackets, of which the 'following is a speciiication.

My invention relates to improvements in extensible brackets for use, particularly, with wardrobe hooks and hangers, though serviceable in any place where an extensible bracket is needed, and its objects are: First, to provide an extensible bracket that will render the greatest possible amount of rigid.- ity with the least possible number of parts and the simplest form of construction. Second, to provide an extensible bracket that may be readily put up, taken down, or adjusted, and, third, to provide an extensible bracket that is capable of supporting extremely heavy loads without too great strain upon its working parts.

I attain these objects by the mechanism illustrated in the accompanying drawing, in which Figure l is an elevation of this bracket as mounted for the support of extremely heavy loads, as in suit cases in large furnishing stores. Fig. 2 is a top plan of the same. Fig. 3 is an elevation of a bracket with the auxiliary support removed and hooks provided or supporting garments, in ,lieu or" the supporting bar shown in Fig. l, and, Fig. 4 is an elevation of the supporting post and its bracket.

Similar letters refer to similar throughout the several views.

In the construction of this bracket I utilize the ordinary form of cross extensions, consisting of links D pivoted together at the ends, as at d, and at the center, as at d, with the iirst link pivoted at the upper end to the supporting post C, and the lower end of the first link slidably secured at the lower end of the supporting post C, as indicated by the rivet C working in the slot l). The last pair of links, D, are made a trifle longer than one half the length of the links I), so that considerable more space exists between the points e andf, than between any two of thc points d', for the purpose of giving the greatest possible amount of leverage for the supporting arm parts Specification of Letters .'Eatent.

F, which is pivotally secured to the links D,

atf.

The arm E is pivotally secured to the ends of the links D, as at e, and has two loops, G, securely attached to it and extending upward to position so that the arm F may pass through them, forming a fulcrum at the extreme back end ofthe arm E, and a proper leverage over this tulcrum and between the pivot point f and the forward loop G to permit of great weight being suspended from the extreme outer end of the arm E without danger of causing these arms to sag under the weight. It will be readily understood that with this construction, the entire series of links, from the point f back to the upper pivot in the supporting post C, will act as a series of well arranged braces, which will render the bracket, practically, as iirm under a steady strain, as irp the arms E and F were lirmly secured and braced in the supporting post C. Another very desirable object attained by this construction, is that as the bracket is being extended the length of leverage between the points c and f is constantly increasing, so that the supporting capacity of the bracket is practically the same when fully extended, to the positions indicated by the dotted lines in Figs. I and 3, as when thrown back to the position of the solid lines in these jligures.

For ordinary use the bracket, in its simplest form, hereinbefore described, is sufiiciently strong and rigid to support any weight that may be placed u on it, and with. this form I provide a series ohooks, J, upon which to hang the diierent articles it is desired to place on the bracket, and a hand piece, J", with which to manipulate the bracket.

In the construction oi this bracket, thc extensible portion is made with two links, D D assing, successively from the pivot point at the head or top of the supporting post C, diagonally downward and inclining away from the post, and a single link passing diagonally from the pivot point C upward between two of the oppositely inclined links and there pivoted properly to give the best results, and so continued until the desired extensible portieri is formed, and each of the arms E and F are made oi two side plates securely riveted together, as indicated at c', so that they must stand absolutely rigid and, with the guidance of the loops G, must always be in exact alinement and bear closely together, so that the sustaining or supporting properties will be absolutely sustained, no matter whether the bracket is extended or withdrawn.

When this bracket is vdesigned to support very great weights, as when used to store a great many suits of mens clothing, I find it much better to provide an auxiliary su port, and for this purpose I provide for pIacing supporting rails, as H, in the up er portion of the case, or other receptac e for the brackets, and securely attach one end of these rails to the support B, and the other end to any desired form of support, as the depending arms Ii K, so arranged that antifriction rollers or small wheels, 7t,1nay be so secured at the point of conjunction of the upper ends of the links D and D, as to travel freely upon, and be supported by the rails I-I, as indicated in Figs. 1 and 2. With this form of bracket I iind it more convenient to replace the hooks J with a rail I, which I.

' secure at one end, to the outer rivet c in the arm E, whence it extends directly downward for a distance, and is then bent backward to form the supporting rail I, parallel with the arm E, with the back end exten ding back far enough to be passed through, and supported by the link I, which is, preferably, suspended from the rivet f, and may be provided with an antifriction roller'i over which the rail will move freely as the bracket is being extended or withdrawn. When this construction is used the loop J may be dispensed with, as the upright portion, i', of the rail I may be utilized for manipulating the bracket.

A represents the wall, or back of the case to which the supporting bracket B is securely attached. This bracket is bent at right angles at each end, and prepared to form a pivotal connection with the post C, so that this post may be made to turn readily therein. In constructing the post C the upper pivot, c, is made long, while the corresponding lower pivot is made short, so that the post C may be readily removed from the bracket B by simply raising it upward and drawing the lower end outward, as soon as the lower pivot has raised out of its bearing at the lower end of the bracket B. This suporting post is made open, as indicated 1n ig. 4, so that the links D may be placed and pivoted between them, as indicated in Figs. l and 3. It will be readily seen that by the construction hereinbefore described, the links are so pivoted together, and to the supporting post C, as to obtain the greatest possible amount of strength and utility from the rivets d and d', with the least possible danger of shearing or cutting them oil", working them loose, or bending and cramping them in their bearings'.

At i', in Fig. 3, I have shown a loop that may be suspended from the links D D for receiving and storing neck ties, ribbons, or other small articles that the owner might desire to place in said loop.

l/Vliat I now claim as new, and desire to secure by Letters Patent of the United States, is:

l. In combination with links pivoted together at the ends and centers to form an extensible construction, a pair of short links pivoted-at one end to the free ends of the two end links of the extension, an arm pivoted to the free ends of these short links and having loops extending upward., a second arm made to slide freely in these loops, and pivotally secured to the crossing point of the links in the extensible construction.

In combination with a supporting post, a link pivotally secured to the upper end of said post, a link slidably secured at the lower end of said post, said links crossed and pivoted together at the point of crossing, a series of corresponding links pivoted together at the ends and at the crossing points to form an extensible construction, short links, but over half length, pivoted to the ends of the last of the series of links, an arm pivoted to the free ends of these short links and having a loop at the end and a loop some distance therefrom and both loops extending upward, an arm passed through said loops and pivoted at one end to the crossing point of links in the extensible series, and appliances on one of the arms for receiving and supporting articles.

3.
