EXTENSIBLE BRACKET.

Specification of Letters Patent.

Patented Oct. 8, 1912.

Application filed March 4, 1912. Serial No. 681,385.

To all whom it may concern:

Be it known that l, A'nrno'usu F. lnnnaa, of Rochester, in the county of Monroe and State of New York, have invcntcifl certain new and useful Improvements in lllxtensihlc Brackets; and I do hereby declare the :tollowing to be a toll, clear, and. exact dcscription of the same, reference being had to the accompanying drawings, :lorming a part oi. this specification, and to the .re'termicc-numerals marked thereon.

My invention relates tocxtcnsible brackets, being especially adapted for supporting a dental cabinet, motor or other object, of the general type employed in dentists ollices and embodying two or more :foldable sections pivotally connected to each other and mounted upon a wall or support, the sections comprising arms arranged in parallelism and serving to maintain the outer end of the bracket and the object carried thereby poised at any point of adjustment, and it has for its object to provide a novel and simple construction and arrangement of parts for accomplishing this purpose.

To these and other ends the invention. coir sists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end ot the specification.

In the drawings: Figure 1 is a side elevation of an extensible bracket embodying a preferred form of my invention; Fig. 9. is a similar View, the sections of the bracket be ing folded; Fig. 3 is an enlarged detail view in side elevation of a modified form of the invention; Fig. 1- is a View .in end elevation 01" the parts shown in Fig. 3; Fig. 5 a side elevation of the form shown in Fig. 3, the sections being folded; Fig. 6 is a side elevation of another embodiment; Fig. 7 is a view similar to Fig. 6, the sections being folded; and Fig. 8 is a sectional View on the line 88 of Fig. 6.

Similar reference numerals throughout the several figures indicate the same parts.

In the preferred embodiment oil? my in vention, the bracket consists of inner and outer sections, the inner section comprising arms 1 and 2, and the outer section arms 3 and 4; respectively, the arms of the sections being arranged in parallelism as shown. The inner section is pivotally mounted on the post 5 which is journaled in a bracket 6, the latter being attached to a wall or other convenient support. The outer section is pivotally connected to a post or standard 7, at the upper end ol. which is arranged a cabinet 8, or other object to be supported.

The inner and outer sections are connected together, and to this end the upper arms .1 and 3 are pivotally connected at 9, while the lower arms 2 and -11; are connected at 10 to the vertically disposed guiding members 11, the latter being in turn connected to the upper arms at 11.2. The seetions are provided with means arranged for movement on, the vertically disposed guiding numbers, and to this end the uppe arms carry the pins 13 which travel in slots 1 1 of the guiding members 11.

The particular form of the guiding members, and the parts which cot'ipcrate therewith, may be varied somewhat, as in the modification illustrated in Figs. (3 to S inclusive. In this form, the vertically disposed guiding members comprise U-shaped members 15 within which travel the slides 16, the latter being slotted at 17 and an ranged to receive in said slots the pins 18 carried at the ends of the upper arms of the sections. lVhen the bracket is folded, the parts assume the position shown in Fig. 7, and when the bracket is extended, the ends oi. the upper arms move upwardly in the slots 17 until they engage the upper ends of the same, and further movement causes the slides 16 to be moved within the U- shaped members 1:") until. they are in the position shown in Fig. (3.

In. Figs. 3 to 5 inclusive, 1 have shown still another modification oi the invention, in which the lower arms oil? the sections, designatcd at 19 and 20, are pivotally connected at 21, the upper arms 22 and 23 being pivoted at 24L to the vertically disposed guiding members 25, which are in turn connected to the lower arms at 26. The guiding members extend upwardly beyond the upper arms, as shown, and are provided at their upper ends with the slots 27. In order to ell'ect equal movement of the sections, ll: provide the links 28 which are pivotally connected to the lower arms at .26, and to each other at 29. Said links are provided with pins 30 which are arranged for travel in the slots 27 of the guiding members, and in this manner equalized movement 01' the sections is obtained at all times, the arms 01 the sections being retained in parallel arrangement, and the object supported remains poised at any position of adjustment.

I claim as my invention:

1. In an extensible bracket, the combination With an inner section including a pair of pivotally mounted arms having .parallel movement, of an outer section pivotally connected to the inner section and adapt-ed to support an object at its outer end, vertically disposed members connected to the adjacent ends of the inner and outer sections, and means arranged on the inner and outer sections movable on the vertically disposed members for causing equal movements of the sections at each side of their point of connection.

2. In an extensible bracket, the combination With an inner section including a pair of pivotally mounted arms having parallel movement, of an outer section pivotally connected to the inner section and adapted to support an object at its outer end, and vertically disposed guiding members connected to the inner and outer sections, the upper arms of the sections being pivotally connected and having their ends movably attached to said guiding members.

3. In an extensible bracket, the combination With an inner section including a pair of 'pivotally mounted arms having parallel movement, of an outer section pivotally con,

nected to the inner section and adapted to on and connected to the inner and outer sections, the upper arms of the sections being pivotally connected together and having their ends movably connected to said guides.

4. In an extensible bracket, the combination with an inner section including a pair of pivotally mounted arms having parallel movement, of an outer section pivotally connected to the inner sect-ion and adapted to support an object at its outer end, vertically disposed members connected to the inner and outer sections at their proximate ends, and sliding connections between the inner section and'the vertical member of the outer section and between the outer section and the vertical member-of the inner section.

5. In an extensible bracket, thecombination with an inner section and an outer section each composed of upper and loWer arms, the upper'arms of both sections having end port-ions overlapping "and a pivot connecting them, of members connecting'the arms of each section for parallel movement, the members located adjacent the pivotal connection of the sections having guides thereon cooperating With the end portions of the arms beyond said pivot.
