UNITED STATES ALEX IETROW, OF SAIT FRANCISCO, CALIFORNIA.

ADJUSTABLE PICTURE-FRAME.

Specification of Letters Patent.

Patented July 26, 1921.

Application filed October 26, 1920. Serial No. 419,708.

To alt whom it may concern:

Be it known that I, ALEX Pnraow, a citizen of the United States, and resident of San Francisco, county of San Francisco, State of California, have invented a new and useful. Adjustable Picture-Frame, of which the following is a specification.

This invention has for its primary object the provision of a picture frame of simple, inexpensive and ornamental construction, which may be adjusted. to receive pictures of different sizes in an expeditious and effective manner, the adjustment being such that the symmetry of the frame will not be disturbed.

Another object is. to provide a frame of the character described which need not be taken apart completely to effect the adjustment thereof, and which does not require particular skill or craftsmanship to effect such adjustment.

The invention has further objects and advantages, some of which, with the foregoing, will be set forth at length in the following description wherein I shall outline in full that form of the invention which I have selected for illustration in the drawings accompanying and forming a part of the present specification. In said drawings 1 have shown one form of the construction of my invention but it is to be understood that I do not limit myself to such form, since the invention as expressed in the claims may be embodied in a plurality of forms.

Referring to the drawing Figure 1 is a front elevation of the frame of my invention; Fig. 2 is a side elevation of the frame; Fig. 3 is a sectional view on the line 33 of Fig. 1; Fig. 4. is a front elevation of the body of the frame; Fig. 5 is a perspective view of one of' the corner blocks of the frame; Fig. 6 is a fragmentary detail sectional view of a portion of the frame; Fig. 7 is a perspective view of one of the corner blocks; Fig. 8 is a perspective view looking upon the underside of the block shown in Fig. 7 Fig. 9 is a sectional view on the line 9-9 of Fig. 1; Fig. 10 is a perspective view of one of the facing blocks; Fig. 11 is a perspective view of one of the backing blocks; Fig. 12 is a sectional view taken on the line 12--12 of Fig. 1; Fig. 13 is a perspective view of a modified form of facing blocks; Fig. 14 is a perspective view of a modified form of backing block; Fig. 15 is a sectional view on line l.5-l.. of Fig. 1 and Fig 16 is a fragmentary perspective view of one end of one of the elements of the body of the frame.

In the present embodiment of the invention I provide a frame or frame body (1) made up of side bars (2) and (3) and end bars (a) and (5). These bars are each provided with a longitudinal slot (6) which slot terminates near but spaced from the ends of each bar. The end bars overlap the side bars so that the slots register and the ends (7) of the bars project outwardly beyond the overlapping portion thereof.

I provide means for adjustably holding the frame bars together and for ornamenting the frame as a whole. This means embodies a series of side bar facing blocks (8), side bar backing blocks (9), facing and backing blocks (10) and (11) respectively, for the end bars, and special corner facing and backing blocks (14) which latter fit upon the ends (7) of the frame bars.

The frame bars and blocks may be formed of wood or metal of any other material as desired. Preferably the frame bars are flat and of wood and the blocks are of the same material and of rectilinear outline, but these elements may be otherwise shaped if desired, provided the bars are adjustable and the blocks perform the office of concealing the bars, holding the bars in adjustable relation and adding ornamentation to the frame.

The side bar facing and backing blocks (8) and (9) are best shown in Figs. 10, 11, 12. Each facing block (8) is rectilinear, being flat on its front side, provided on its back side with a tongue (15), and having upon its inner edge flush with the front side, an inwardly projecting picture retaining portion or flange (16). The inner side of each block (8) is flush with the correspond ing side of the side bar except for the portion (16) which projects inwardly from these sides. The tongues (15) engage snugly in the slots (6). The outer sides of the blocks (8) are spaced inwardly from the outer edges of side bars as shown clearly in Fig. 12. The backing blocks (9) (see Figs. 11 and 12) each comprise a fiat rectilinear body (17) having a right angular extension (18) on its outer edge. The bodies (17 engage upon the rear sides of the bars (2) and (3) and the extensions (18) project outwardly in front of and along the outer edges of said side bars. The extensions (18) have inwardly projecting flanges (20) intermedia purpose as the portions (16).

. ting the blocks (8).

blocks ately arranged on their inner sides and these flanges engage and conceal the portions of side bars between the blocks (8) and extensions (18) with their outer edges abut- Since the outer edges of the extensions (18) are flush with the front faces of the blocks (8) a groove as at (21) is formed in the sides of the frame. The blocks (8) and (9) are fixed one in engagement with the other upon the side bars (2) and (3) as shown in the drawing, conceal said side bars and provide ornamental side frame members, the groove (21) formed as described accentuating the ornamentation. These blocks are held upon the side blocks slidable thereon; however, by countersunk screws (22) which are inserted from the rear sides of the blocks (9) through said block and the slots (6) and turned into the tongues (15) in the blocks (8) each block (8) and its backing block (9 is a frame unit slidable upon the side bars.

The end bar blocks (10) and (11) are similar in construction to the side bar blocks except that the facing blocks (10) are thinner and have tbngues (23) nearer to the outer edges thereof than are the tongues (15). This provides inwardly projecting portions (24) similar to and for the same The backing blocks (11) are thicker in the bodies (25) thereof and the right angular extensions (26) are shorter than the similar portions of the blocks (9), (see Figs. 13, 14 and 15). The outer edges of the blocks (10) arespaced from the inner sides of the extensions (26) and the exposed portions of the end bars (4) and (5) lie the same distance inwardly from the front faces of the block (10) as do the flanges (20) relative to the Thisprovides a groove (27) corresponding to the groove (21). The difference in construction in the side and end blocks i necessary because of the overlapping of the frame bars, which overlapping disposes said bars in different planes. Screws (28) secure the blocks (10) and (11) together so as to permit of the sliding thereof on the end bars. The blocks (8) (9), (10), and (11) which abut at the corners of the frame are beveled so as to fit closely together as shown at (29) in Fig. 1. The corner blocks (12) and (13) are best shown in Figs. 1, 7, 8, and '9. The blocks (12) each have a pyramidal front side (30), and upon theirbacks each are provided with two tongues (31) and (32), one at one edge of, and the other intermediately disposed upon, said block. The tongues (32) engage in the slots (6) of the end bars (4) and (5) and the tongues (31) extend along the outer edges of said bars. The blocks (13) have tongues (33) and (34) similar to the tongues (31) and (32). The tongues engage in the slot (6) of the side bars (2) and and the tongues (34) extend along the inside edges of said bars (2) and (3) and abut the under or rear faces of the block (12). Screw holes (35) are provided in the tongues (33) and receive screws (36) which screws are turned into the tongues (32) of the. blocks (1.2). These corner blocks hold the frame bars adjustably together. The end blocks (14) are best shown in Figs. 1, 5 and 6 and have recesses (37 cut therein so as to receive the ends (7) of the frame bars. These blocks abut the corner and side and end blocks when in place and have grooves (38) therein arranged to aline with the grooves (21) and (27 These grooves (38) appear as the extremities of the grooves (21) and (2'7). To adjust the frame so as to make it smaller certain of the blocks (8) and (9) on the side bars (2) and (3) and certain of the blocks (10) and (11) on the end bars are removed preferably from points intermediate the ends of said bars. After removing these blocks the frame bars are moved together by sliding them through the removing blocks, until the remaining blocks abut one another. The projecting portions (7) are lengthened and the blocks removed are mounted thereon so as to conceal these portions of the frame bars. It will thus be seen that I mayadjust the frame in various ways to provide for the mounting of pictures of different sizes in said frame. The frame may thus be made square or rectangular, larger orsmaller as desired.

I claim: 1

1. A picture frame comprising frame bars, and a plurality of blocks in which said bars are slidable, said blocks abutting one an other and concealing the said bars, and means for removably securing the blocks upon the bars.

2. A picture frame comprising a plurality of blocks, frame bars slidable between and concealed by said blocks, and means for removably securing the blocks to the bars.

3. picture frame comprising slotted frame bars overlapping one another at the ends, means for adjustably holding thebars assembled to form a frame comprising blocks mounted. upon and concealing the front and rear sides of said bars, and means for removably holding the blocks together.
