ARTHUR W. ANKENY, OF INDIANA, PENNSYLVANIA.

ADJUSTABLE WORK-SUPPORT.

Specification of Letters Patent.

Patented Dec. 12, 1911.

Application filed February 17, 1911. Serial No. 609,078.

T 0 all whom it may concem:

Be it known that I, ARTHUR W. ANKn-NY, a citizen of the United States, residing at Indiana, in the county of Indiana, State of Pennsylvania, have invented certain new and useful Improvements in Adjustable Work-Supports; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improvement in article supporting brackets generally, and more particularly to bracket attachments for drawing desks.

The principal object is to provide a bracket for drawing desks for supporting objects to be drawn.

Another object of the invention is to provide a bracket for the purpose described which can be adjusted to various heights and shifted to various angles in order to properly position an object for an artist.

A further object of the invention is to provide a device of the class described which can be easily assembled or disassembled and when in the former position will be securely retained against accidental displacement.

A still further object of the invention is to provide a device of the character described which is extremely simple in construction, is composed of a minimum number of parts, and is therefore cheap to manufacture.

lVith these and other objects in view, the invention consists in the. construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the appended claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings :Figure 1 is a perspective view showing my invention applied to a drawing desk, Fig. 2 is an enlarged front elevation of the plate, Fig. 3 is an enlarged rear elevation of the plate, Fig. 1 is a sectional view of the plate taken on the line 11 of Fig. 2, Fig. 5 is an end view of the plate showing a book supported thereby, Fig. 6 is an enlarged sectional view through the corner fastening of the bracket, Fig. 7 is a detail sectional view through one of the flower-stem openings, Fig. 8 is a perspective view of one of the spring-engaging clips, Fig. 9 is an elevation of the clamp showing the adjusting means for the rod, and Fig. 10 is a vertical sectional view taken on the line 1010 of Fig. 9.

Like reference characters indicate corresponding parts throughout the several views.

Referring to the drawings the reference numeral 5 designates a drawing desk of any suitable construction and having a top 6, the edge 7 thereof preferably overlapping the contiguous side wall. Attached to the said edge 7 of the desk is a clamp designated as a whole by the reference numeral 8. This clamp is preferably formed of cast-iron and consists of opposed leaves 9-9 and a connecting end portion 10. The leaves 9 are disposed on opposite faces of the top and are fixedly secured thereto by a clamping screw 11 which is carried by one of said leaves. Centrally formed in the connecting portion 10 is an opening 12 and disposed within this opening is a secondary clamping member 13, the inner end 14 thereof preferably frusto-conical and the inner wall of the said opening 12 is correspondingly shaped. Extending forwardly of the connecting portion 10 and integral with the portion 1 1 is a head 15 having an elongated opening 16 formed therein. Movably secured to the outer end thereof is a clamping bolt 17. It will be observed that this secondary clamping member 13 is rotatable and is disposed at right angles to the connecting portion 10 of the primary clamp. Formed in the outer face of the connecting portion 10 is a plurality of grooves 18 which radially project from the opening 12 thereof.

Disposed within the opening 16 of the secondary clamp is a supporting rod 19 and this rod can be shifted to or fro and retained in any adjusted position by being fitted in any one of the said grooves 18 and retained therein by the clamping bolt 17. It will also be observed that upon releasing the bolt 17 the said rod 19 may be adjusted to different heights as may be desired. The upper end 20 of the rod 19 is reduced and preferably rectangular in shape.

Extending laterally from the upper end of the rod 19 is a bracket arm 21 which is provided at one end with a rectangular opening 22 adapted to receive the reduced end 20 of the said rod and at its other end with a reduced elongated circular portion 23.

The invention further comprises a brace 24 of any suitable design which is provided with projecting spurs 25-25, said spurs being preferably disposed at right angles to' each other. These spurs are detachably seated within corresponding openings 26 and 27 formed in the arm 21 and rod 19 respectively. This brace it will be observed is detachable and by reason of the spurs being arranged at right angles a very eifective brace is thereby produced. Formed in the arm 21 are spaced openings 28. These openings may be disposed at various angles but they are preferably disposed vertically. These openings are oppositely tapered, and. associated with each opening is a flat spring clip 29having a pointed end 30. The said clip is secured to the arm by any suitable means and the pointed end 30 thereof projects into the opening 28 and is adapted to pierce the stem of the flower or the like and thereby secure the same in position. It will be observed at this point that by forming these openings in a tapered manner the stem of a flower can be easily guided thereinto and that by reason of these said openings being oppositely disposed the flowers may be retained above and below the said arm as may be desired.

The invention further comprises a plate or support designated as a whole by the numeral 31. This plate is preferably formed of sheet metal and is rectangular in form. The plate consists of a body portion 32 and upper and lower portions 3333. Inasmuch as the end portions together with the hereinafter described attachments are identical the description of one will suffice. The end portion 33 is hinged to the body 32 by a knuckle-joint 34 and pin 35. The adjacent knuckles of the hinge are respectively provided with abutting shoulders 36 by means of which the rearward movement of the end pieces 33 is limited. In other words these shoulders prevent the said end pieces from moving rearwardly out of the plane of the body portion 32. Extending inwardly from the outer edge of the piece 33 is a centrally disposed slot 37, thereby forming spaced ears 38. The outer or front edges of the ears 38 are bent to form alined sleeves 39 and disposed within the said sleeves is a pin 40 which is preferably formed of steel, said pin extending across the said slot 37.

A spring wire 41 is disposed longitudinally of the piece 33 and in substantial alinement with the connecting wall 42 of the said slot 37 and is secured to the piece 33 by any suitable fastening means. Disposed within the slot 37 is a movable plate 43, the outer edge 44 thereof being bent to form a bearing sleeve which is positioned on the pin 40. The opposite edge is also bent to form a sleeve 45 which is adapted to engage the spring rod 41.

A wire clip 46 is bent to form an elongated loop 47 which normally lies against the body portion 32 and tends to keep the pieces 33 in alinement therewith. This spring clip eX- tends centrally from the loop around the plate 43 and thence forwardly of said end pieces to form a finger-piece 48 by means of which the said block 43 can be elevated as shown by Fig. 5 of the drawing.

Secured to the back of the body portion and adjacent the end pieces 33 are springs 49 one end of each spring being secured to the said body portion and the other end 50 being bent at right angles for normally engaging the contiguous piece 33. Thus it will be observed that when the pieces 33 are swung forwardly the end portions 50 of the springs will engage above and below the respective pieces and thereby form supports for the same.

Secured to the back of the plate is a suitable bearing boX 51 which is adapted to receive the reduced end 23 of the bracket arm 21. By means of a wing-bolt 52 the said plate can be secured at various angles as will be readily understood.

From the foregoing it will be observed that an artist will desire to have an object suspended in an inverted position. lVhen this is desired the upper spring clip 46 is employed. lVhen, however, it is desired to support an object in its normal position the lower clip 46 is employed. Articles having considerable thickness, such as books or the like, can also be retained by this plate. When such articles are employed the lower piece 33 is swung forwardly and retained therein by the clip 49 as before mentioned, and the finger piece 43 depressed thereby elevating the block 43 and the loop 47. The article can then be placed intermediate the loop 47 and the body portion 32 of the plate and the same will be retained therein.

Whenever it is desirous of swinging the bracket arm 21 the clamping bolt of the secondary clamp can be loosened and said arm swung to the desired position. Whenever it is desired to dispense with the use of the bracket the said vertical arm can be lowered, together with the bracket in such a manner that the latter may be positioned directly upon the desk. Thus in this position the bracket and rod are both entirely out of the way.

What is claimed is 1. An attachment for desks comprising in combination, a clamp, a secondary clamp rotatably carried thereby, a rod adjustably supported by said secondary clamp, a bracket-arm detachably supported by said rod, said arm being provided with a plurality of tapering stem-receiving openings,

and spring stem-penetrating clips carried by the arms and having pointed ends projecting into said opening.

2. An attachment for desks com rising in combination, a clamp consisting o opposed leaves and a connecting end portion, said portion being provided with a centrally disposed opening, the inner end thereof being flared, said connecting portion being also provided with a plurality of grooves projecting radially from the said opening, a secondary clamp disposed Within the opening and having an inner end corresponding in shape to the inner end of said opening and having its outer end projecting forwardly thereof and provided with a head having an elongated opening, a rod disposed within the opening of the head, means carried by the head for securing the rod in any of the grooves of the connecting portion of the first mentioned clamp, a bracket-arm supported by said rod, and an article support carried by the arm.

3. An attachment for desks comprising in combination, a clamp, a secondary clamp rotatably carried thereby, a rod adjustably supported by said secondary clamp, a bracket-arm supported by said rod, and an article support carried by the bracket-arm, said article support consisting of a body portion having upper and lower end portions hingedly connected thereto for forward movements, springs carried by the body portion for respectively engaging and supporting an end portion when the atter is swung forwardly, and a spring article-engaging clip carried by the front ends of each portion.

4. A work support formed of sheet metal comprising a body, top, and bottom portions, hinges respectively connecting the end portions to the body portion, each portion being provided with a centrally disposed slot forming consequent ears, a pin carried by the outer ends of the ears and extending across the slot, a spring rod secured to the end portion on either side of the slot and disposed adjacent the inner wall thereof, a plate arranged within the slot and having its opposite ends respectively secured to the pin and the spring rod, and an article-engaging spring clip carried by said plate, said clip having its ends projecting beyond the portion to form a finger-piece.

In testimony whereof, I afiix my signature, in presence of two witnesses.
