Specification of Letters Patent.

Application filed April 2, 1909. Serial No. 487,405.
1To/cll whom it may concern:
Be it known that I, Roenn'r L. Coonnv, a citizen of the United States, residing at Mil- Waukec, in .the county of Milwaukee and State of Wisconsin, have invented certain -...new and useful Improvements in Folding ,St ands, of which the following'isa specification, reference beinghad to the accent panying drawing, forming a part thereof.
This 1nvent1on relates more particularly 1. *toidevices for supporting in convenient pos t on for drawing or otherwise copying various objects such as models, leaves, twigs,
flowers nctures etc.- Its main ob ect is to provide aconvenient, light, port-able and sadiu-stable device for this purpose which a. connected at intervals by rounds or cross when not in use can be easily folded into small compass for storage or transportat-ion,v and when set up for use will display the objects to be drawn. or copied under the almost-ffavorable conditions.
lt consists in the construction, arrange naent-.-and comb nation of parts as hereniafter particularly described and defined 1n the claims.
J I .In the accompanying drawing like characters. .designate the same parts in the several figures.
..F-igure 1 is a perspective view of the stand,
spread or open in condition for use; Fig. 2
= 1s a back view of the stand folded; and Fig.
is a longitudinal section on the line 3 3, Fig. 2.
iilg support pivotally connected therewith oted inthe upper part of the main frame, and a folding-back pivotally connected with the shelf. 7
. The main frame consists of two side pieces pieces I). The folding support which is preferably about half the length of the main frame consistsv of side pieces 0, which are connected hyrounds or cross pieces (2. The
pieces a of the main frame. The support is made to close inside of'the nain frame, as shown in Figs. 2 and 3, and the lower ends of its side pieces care beveled or cut away on the front side so as to close against the lower round or'erosspice b, which serves-as a stop to preventthe support from swinging forwardbeyondathe sides-of the frame when the standis closedkAdjacent to he uppe The stand comprises a main frame, a fold-.
ends the side pieces 0 are formed in their rear edges with correspomlingly spaced series of notches c, and in the side pieces of the main frame below the upper round. or
stand. Adjacent to its cross piece the sides of the brace are bent Tupwardly or rearwardly as shown in Figs. 1 an'd'S, so that when the stand is folded they will lie between the side pieces of the frame and support.
One of, the side pieces (1.- of the frame is provided. on the inside with a spring pin or yielding catch 9, which is arranged to engage with the adjacent side of the brace) and hold it with the folding support 0 closed A folding leaf or shelf 7!, is hinged or pivoted at its rear edge'in the upper part of the main frame. This may be convcnlently accomplishcd by means of screw eyes i, inserted in the shelf and. encircling the upper round 6. A brace 7' which may be made of heavy wire as shown,.bent at its upper end at right angles to form a pivotpin and stop 7c and. at its lower end 'to form a guide loop -Z around the adjacent side piece a of the frame, is hinged or pivoted to the under side of the shelf by a hinge plate m. The
.side piece a which is loosely embraced'by the guide loop Zj of the brace,- is formed in its upper or front edge with a series of notches n spaced for engagement .Withthe front side of the loop Z so as to hold the shelf ina horiZonta-l position when the stand is spread or open. The notches n are spaced to correspond withthe notches 6, so that the brace 3' may be adjusted to hold the shelf in horizontal position accordingto the adjustment of the brace f, which determines the height of the stand. or the-elevation of the shelf from the floor. The back 0 which serves as a background for objects placed on. the shelf h and as-a support for the attachment of pictures, leaves, twigs,. flowers and other obiects to 'be-.copicd,,is hinged to the shelf adjacent .toits rear edge so as to be folded against. it, or opened and held in a position:
perpendicular thereto. a
To formthe-hinge connection between the. shelf and back and'to hold the back in the desired-positions with relationto the cross piece kt are pivoted the outwardly bent ends of a bail-shaped brace 7", which may be made of heavy wire and adapted to be i-zngagzd with corresponding notches c in the support to determine the extent of the opening of the support and the height of the engages to the back, projects therefrom into a mor-- tise or opening 1' in the shell-and cleat to hold them in the proper relation to each other.
springs s which tendl=to hold the back in a position perpendicularrto the shelf, as shown 1n Fi .1, when the stand is spread or opene In this position of the back the tongue g engages with the front side of the mortise T, but when the shelf is closed or folded, as shown in Figs. 2 and 3, the tongue with the. under or inner side of the cleat p. The cleat is made somewhat shorter than the width of the shelf,fand the ends of the back adjacent thereto are cut away or recessed to receive the springs s and permit them to pass between the side pieces a of the main frame when the stand is closed or folded. One of theside pieces a of the framt is provided with a spring catch 16 which" is arranged to engage with the adjacent end'of the back 0 and to hold it with the shelf h in place between the sides of the frame when the stand is closed or folded. By enga 'ng the cross piece of the brace f with di erent notches e in the folding support, the height of the stand and the elevation of the leaf '71, from the floor may be varied 1 as desired, the loop Z of the brace 1' being correspondingly adjusted to support.
the leaf in a horizontal position.
' In setting the stand up for use, the support a is swung back into position to carry v matically v j sliding the leaf or shelf h at the desired elevation and is locked and held in that position by engagin the brace f with'the' proper notches eaf or shelf 'is then turned up into a horizontal position, the loop Z of the brace freely upward on. the notched side piece 0;, and the upper side of said loop dropping into the next notch n below it and autolocking the leaf or shelf in place whenit is released by the hand. Finally the back Q is turned up into a vertical position in which it is stopped by the cleat. p and tongue 9 and held by the springs '8. To fold or close the stand, the loop Z is lifted and held out of engagement with the notches na while the leaf or shelf h is turned down into place between the side pieces of'the frame. As the leaf is brought into this position the under or rear side of saidloop, which assumes an oblique position relative to the notched side piece a, engaging the under-or rear edge of said side piece, as
- shown in Fig. 3, draws the upper or front sideof the loop into the lowest notch, thereby stopping and holding the shelf between and substantially parallel with the side the main frame and the brace f The back is connected at the ends. with the ends of the shelf or cleat p by spiral pieces of the main frame. The back 0 is then folded and held by the catch t a ainst the leaf h. Finally, the support 0 is olded against the lower round or cross piece I) of is folded upon it and held in place by the catch 9. When thus closed or folded the stand occupies ver little room, all its movable arts are con ned in place, and in this con ition it can be easily carried from place to place. A number of stands can'also. be nested or packedesnugly together within small compass for storage or transportation.
Various modifications in the details of construction and arrangement of parts may be made without departing from the princi-' ple and scope of the invention.
1. In a folding stand the combination of a main frame, a support pivotally connected at one end with said frame about midway between the ends thereof, a brace-for connecting said frame and support and limiting the extent of o ening thereof, a folding shelf pivoted a jacent to its rear edge to the upper part of said frame and a brace for connecting said shelf with said frame and holding the shelf in a horizontal position. l
- 2, In a folding stand the combination of a main frame, a support pivotally connected with said frame about midway between the ends thereof, a brace adapted to adjustably connect said frame and support and to vary the'height of the stand, a folding shelf pivoted adjacent to its rear edge to the upper part'of the frame and a brace adapted to adjustably connect the shelf with the frame and to tal position. 4
