Dec. 9, 1941. J. A. scHucK FRAME Filed Aug. 18, 1938 -INVENTOR TTORNEY Patented Dec. 9, 1941 UNITED STATES PATENT OFFICE FRAME Joseph Alfred Selim-ck, Bound Brook, N. J. Application August 18, 19st, Serial No. 225,543

'7 Claims.

This invention relates to a frame, which serves as a support holder and stand for flat objects to be exhibited, such as tablets, boards, mounted pictorial presentations or legends, which may for instance be assembled with a protective and reinforcing transparent plate or sheet, such as glass. Such an object will hereinafter be defined as a stiff sheet object.

The general object of this invention is to provide a frame, which may be readily, replaceably and at random applied to a stiff sheet object of any size, and will thus facilitate the setting up or hanging of the object onto a suitable support, i. e. a level, inclined, or upright structure, such as a table wall or column.

Other objects of this invention, which are mostly incidental to the general object just stated, will be elucidated in, and better understood from the following exemplary description of the invention. The description together with the accompanying drawing should be interpreted as illustrative rather than in limitation of this invention.

In the drawing:

Fig. 1 shows a perspective view of a device of this invention which is applied to and supports a flat sheet object.

Fig. 2 is a detailed view showing a cross-section taken at a level and in a direction pointed out in Fig. 1 by a dot-dash line, an arrow and the numeral 2.

Fig. 3 .is another detailed cross-section, the direction and level of which is pointed out by a dot-dash line and an arrow and the numeral 3 in Fig. 1.

Fig. 4 is a sectional plan view of a sheet which may be used supplemental to a frame of this invention.

Fig. 5 is a sectional, developed view of another supplemental sheet made of rubber or like material.

Fig. 6 is a sectional view of a supplemental sheet which is modified as compared with th embodiment of Fig. 5.

Fig. 7 is a horizontal cross-section of a plug supplemental to a frame of this invention.

Fig. 8 shows a corresponding vertical crosssection.

Fig. 9 shows an elevation of sheeting used in connection with the device just referred to.

Fig. 10 is a corresponding top view.

Similar numerals refer to similar parts throughout the various views.

Unless some readily available auxiliary means are used, a device of this invention does not serve to support a limp object structurally in its plane. In this respect a device of this invention differs from the ordinary frame, which usually surrounds a sheet object completely, thereby normally also supporting it in its plane. The sheet M be provided for such purpose. offset to one side, i. e. they extend through the object referred to is therefore generally defined as a stiff sheet object, it being understood that a limp sheet object may readily be converted into a stiff sheet object by a suitable backing or covering.

A device of this invention comprises a pair of brackets, which may be substantially aligned. But, for purposes of economy of material and still providing a maximum structural strength and stability, the brackets may be made symmetrical to each other, i. e., there is a right bracket II, and a left bracket I2. This arrangementwill also effect a certain harmony of the appearance; although appearance is not emphasized herein. It is understood, that the appearance of a device of this invention may be vastly improved upon; but this specification is limited to the simplest details required for an embodiment of this invention.

Each of the brackets comprises a riser l3 and a leg H, which in the drawing is shown as complementary half-round sections, rounded off at opposite ends, and pivotally pressed together by a screw 15 at a fulcrum joint. Thus they are frictionally engaged uponeach other, and-the riser and leg may be swung into alignment, when they represent a substantially round cross-section. However the leg I does not necessarily have to be as long as the riser l3. i

It is desirable to have such frictional contact between the riser l3 and the leg l4, that they are fairly stable at any setting, when a stiff sheet object is mounted therein and supported thereby. Thus frictional contact between the riser and the leg may be improved upon, by providing additional securing means at the fulcrumed'point, or by providing a spring or spring washer l6 underneath the head of the screw l5, which is shown in Fig. 3 as a shoulder screw.

A stiff sheet object is indicated in the drawing as a commonly used embodiment, i. e. one or more pictorial representations l1 engaged between a pair of glass plates [8 and [9. --A longitudinal slot 29 divides the upper portion of the riser l3 into bifurcations or forks 2| and 22, and is of such width that it accommodates a stiff sheet object of an average thickness, together with some spacing or gripping means, which will be presently explained.

Means ought to be provided which clamp together the forked ends 2| and 22, produced in the riser l3 by the slots 29. According to the drawing, one or more thumb screws 23 and 24 may Such screws are end 2! near the lateral outer surface thereof, and into the other end 22, where they are thread edly engaged. The stifi sheet object is inserted in the slot 20 together with spacers or elastic sheeting, so that the width of the slot 20 is substantially filled, and then the ends 2| and 22 are clamped together by manipulation of the screws 23 and 24, this operation being repeated in connection with the left bracket l2, after it has been performed in connection with the right bracket I I. The slot may be flared out wider for a certain distance near its outer end, as indicated at 26, so that the stiff sheet object is firmly retained in slots 20, rather than being squeezed out thereof.

When spacing sheets 21 are used, they are pref 7 erably notched in order to clear the tensioning means such as screws 23 and 24, and so that one or more of these spacers may be inserted at random, each spacer being for instance made out ofcardboard. i A' firmer. engagement of the stiff sheet object which is provided with a plurality of perforationsv 29, near the center line, these perforations fitting oVer'the shanks ofthe thumb screws 23 and 24. If thespacers 28 are made out of rubber,

. but are fairly stiff, they will always spread apart object-25. I r r But in place of these perforations 29, the clastic sheet '28 may also contain slots 30, which correspond to the notches of the spacer 21, so that the folded sheet 28 may be placed over the edge of. the stiffsheet object 25, before it is inserted into'aslot 20. Risers I3, and legs M are ex-- emplarily indicated in the drawing as being made of wood, but any other material of suitable resiliency, such as metal or molded material, may be used and-shaped as fancyand fashion may dictate. Theriser l3, should of course beof such width, that it liberally engages upon the margin of a stiif sheet object alongside of the clamping means such as thumb screws 23 and 24. And it, should be of such cross-section that it is not readily twisted when the forks 2| and 22 are pulled together" for clampin purposes.

When the stiff sheet object is assembled from a'plurality of sheets, it might gape along an outside -margin, when clampedly engaged alongthe' lower sides by the brackets H and I2. Then it may be advisable to use suitable plugs 3| for the corners and 32- for theupper edge, in connection withthe brackets II, and I2. lugs 3| and 3 2 may be slotted angularly or across respectively, preferably with bevelled entrance corners, such; as indicated at 33, in connection with the slot 34 in thespherically. shaped lugs 3|. The lots, 34may be gouged so as to be wider at theinbottoms. This is particularly helpful in connection with spacers or molded rubber formae in 'order to allow "ready insertion of a stiff sheet Such tions 35, whichserve to fill the ,slot when it is asthe state of the art and the appended claims may require, for it is obvious that various modifications and changes may be made in the form of embodiment of my invention, without departing from the spirit and scope thereof.

What I claim is:

1. A frame comprising a pair of brackets, each of said brackets including a riser having forked ends separated by a slot of a width suitable to receive a marginal portion of a stiff sheet object, and having clamping means on one side of said ends for pulling them together into clamped abutment with an objectplaced into said slot.

2. A frame comprising a pair of symmetrically arranged risers which are slotted from the top down but short of their lower ends, screws offset to one side on said risers and serving to pull the upper ends of said risers together across said slots, in order to clamp upon a stiff sheet-like object inserted on its opposite sides into said slots, said risers being relatively spaced and secured in a common plane by such an object, and a support extending from one of said risers in a plane substantially normal to said common plane and adapted to be set at a preferred angle in said normal plane. 1

3. A frame comprising a pair of risers bifurcated for a major portion of their length, clamping means interconnecting the bifurcations of each riser on one side, so that opposite sides of a stiff, sheet-like object-to'be framed may be inserted and engaged between the bifurcations of each riser from the other side of said'riser, said risers being relatively spaced 'and secured in a common plane bysuch an object, and a support extending from one'of said risers in a plane? substantially normal to said common plane and adapted to be set ata preferred angle in said normal plane. Y

4. A frame comprising a pair of risers bifur-' cated for a major portion of;their length, the bifurcations of each riser. being farther .apart upon one side than on the other, and screw means interconnecting the bifurcations of each riser on the farther apart side, so that aniobjectto be framed may be inserted between the. bifurcations of each riser from theopposite side thereof where the bifurcations are closer together.

5. A frame comprising a, pair of brackets, each of saidbrackets including ajbifurcated riser, contracting means for clamping said bifurcations side ways onto a stiff sheet object inserted there between, and a leg 'clampedly fulcrumed onto said'riser so that said riser. and leg may. be set at random at a preferred angle with each other, at which the risers and an, object clampedly engaged thereby are to be supported on a supporting surface. j

6. A frame comprising a pair of brackets, each of said. brackets, including a bifurcated riser, screws for clamping said bifurcations onto a stiff sheet objectinserted therebetween, and a' folded sheet of elastic material perforated on opposite sides. of the fold in order to receive said screws and shaped to fit between said bifurcationsover an object inserted between said bifurcations.
