EXTENSIBLE FRAME.

Application filed February 12, 1923. Serial No. 618,705.

To all who-m t may concern.'

Be it known that I, JULES LEMERY, a citizen of the Republic of France, and residing at Dieppe, Seine Infrieure Department, No. 34:, Rue du Gnral Chanzy, in the Re public of France, have invented certain new and useful Extensible Frames, of which the following is a specification.

The present invention refers to an extensible frame which is principally intended to allow the painters to show to their purchasers their paintings 'or pictures of different sizes suitably framed, without the necessity Vfor them to incur the expenses or have the trouble of a large number of frames. The same can also be arranged so as to serve as an extensible framing to be used for maintaining in a stretched state the canvas to be painted upon.

This extensible frame is composed of members or parts sliding the one above the other and of a small number of intermediate members which are used for filling up the empty spaces of variable length which are left between the ends of the sliding members or parts.

The accompanying drawing shows by way of example several forms of construction of a frame made according to the invention.

Fig. l is a `itront view of this frame, certain intermediate parts being in position while some others have been removed.

Fig. 2 is a rear view thereof.

Fig. 3 is a section of same made according to line A-A of Fig. 1.

Fig. l is an elevation of a second form of construction of the frame, certain parts or members being broken away or removed.

Fig. 5 is an elevation Iof a third form of construction the intermediate parts being removed.

Fig. 6 is a cross section made, on a larger scale, according to line B-B o'fFig. 5.

Fig. 7 is an elevation of a fourth form of frame, adapted to be used as a framing for stretching the canvas which is to be painted upon.

Fig. 8 is a cross section made according which are provided with corresponding manner forinstance by means of screws 3 or simply by-means of glue, etc.

Eachrear element on one side of the frame is rigidly secured to the front element of one of the adjacent sides of the frame. The rear element of each side of the frame is slidable upon the front element of the same side of the frame.

The members l andV 2 are suitably grooved 65 so that they may'be'able to slide longitudinally the one with reference tothe other, the memberl 1 comprising' a groove l in which enters a corresponding tongue 5 of the member 2. 7O

These grooves and tongues can be dovetailed so that the members can be tightly maintained the one against theY other. Furthermore, the guiding can be obtained if necessary by means of slides made of metal or lined with metal in order to secure a greater strength and an easier sliding, if deemed necessary. f

Moreover, each member l comprises a longitudinal mortise 6 in which slides a bolt 7 secured to the corresponding member2;V nuts 8 allowy to maintain the parts well pressed the one against the other in every one'of the positions in which they have been placed. Si

Of course, this mode of fastening has been given by way of `example only, and can be replaced by any other similar one.

In order to lill the empty spaces existing between the members, I make use of intermediate members or parts such as 9which are preferably provided with studs 10 and mortises or slots 11 so as to be perfectly connected at their ends with the members l a; slots or mortises and studs.

Whereas 'there is a limited number of sizes of canvas currently used, it is only necessary to have a small number of intermediate members of different lengths in order to impart to the frame all the required sizes, as well to the height as to the width.

Fig. l shows the frame in front view, two intermediate members 9 being in posi-V tion, the two others being removed.

Fig. 2 shows the back 40f the same frame.

Studs 12 and slots or mortises 13 can also be provided at the ends of the members l'.

It is obvious that the members 2 and the intermediate parts 9 can be of any profile,l H" that the said members or parts can be gilt or ornamented in any suitable manner.

vas to lill the intervals.

If necessary, the ornamentations-can be such that the joints of" the members 2 and 9 will be concealed as well as possible.

In the form of construction which is shewn in the dnawings, the members 2 and 9 are provided with a rabbet 1/1 into which the paintings lare located.

According to Fig. 1, the frame comprises four angle-pieces which are L-shaped and the ends of which c're preferably cut Laccording to ornamentallinesg-for exian'iple, as' shewn in the drawings so that ythe oints may be more easily concealed.

These parts 15 are connected' through straight parts 16 which are' situated at 'the rear part `of the fria-me andvcomplr'ise grooves 17 in which enter boltsff'l connected with the Iparts 15, the fastening being. obtained by means ofv nuts 8, as previously set forth. v

Intermediate members 9, bordered,- moulded, or ornamentedin the same way asthe parts 15 are located between the latter so maintained for example by means of bolts 7 and nuts 8, like the previous" ones (which have notV been represented).

Projecting ornamentations 18 preferablyv cover" the joints so asl toV entirely conceal prlises aV front partA 19 and back part 2Ov rigidly connected together and for-'ming an angle piece, as in the pn'evious forrmv of' con'- struction, but instead of -being mitered the ends ofthe part or 'member' 19 areV cut at right angle with reference tothe direction of the sides o-f the' frame, as shewn` in 21 and 22,' which is more advantageous With reference to the perfectness of the jointsand the facility of concealing the same.

The member 19 carries a bolt 7 which passes through a groove 6y ofthe part- 20 belonging to the following vangle of t-he frame, and these two parts are guidedthe one above the other by means of strips or mouldings- 23 located inthe grooves 24 of t-he part 2O and sliding in grooves 25 of the member 19. The fastening at the re' quired place is obtained by means of' nutsr 8' which are screwed upon the bolts-7. As' in the previous case, the empty places'existing between the front parts 19 are filled by intermediate members such asf26 lhavimg" the same section and the same' ornamentation as themembers 19.

In order to' maintainV theseI members in position, it may beonly necessary'tof provide These parts` are jection 28 tixedto the adjoining part 19, andl at the opposite end, a projection 29 entering into a slot 30 of the corresponding part 19.

0f course, any other suitable fastening means can be use d for the same purpose, for instance other bolts 7 and other nuts 8 similar to4 those which secure the parts 19 to the parts 20.

The frame shewn4 in Figs. 7- and 8 differ from the one which liasfbeen` previouslydescribed in" that the parts or members` 19 and 20have a trapezoidal cross section in order to forma slightly dished frame so thatV the canvas to be painted upon which will be stretchedv over the frame and nailedy around its periphery will be solely supported by the ridges 31 ofthe frame.

In order to avo-id the yielding of the long sides of the extensible framev under the action of the tension of .the canvas it may be useful2 to interpose between them crossties or stays the lengtlr of which can be adjusted; such a tie` can for example consist of a threaded irod or stenr 32 which freely slidesv ,in a tube 33 andy which carriesa nut Beso arranged? asf to bear against an end of this tirbe; the other end of the tube carries a studv 35I which enters one of the holes 36 provided' in one ofJ the members 2O while the external end of the rod 32 enters" one of the holes 36 ofthe oppositeA part 20. It is only necessary to turn the nut 34" in order'to modify, according to the requirements, the length of the exten sible cross-tie which is-thus constituted.

The rear portions ofthe frame adapted. tov receive the tacks or nails for fixing the canvas vare preferably made of soft woorl oir lined with Ysoft wood, While the front members 19 and 26Y can be made of yhard wood or lined with metal so as`- to insure the necessary rigidity and strength.

Claim An extensible frame for paintings or pictures comprising L-shaped ang-le parts. the two arms of each angle part being placed i-n two diiiferent front and rear planes and being rigidly fixed the one against the other, means for Vguiding and fixing. the front arm o-f each angle part to the rear arm of the following angle part, and intermediate parts of different lengths adapted to fill the variable empty spaces provided be tween the iinont arms of the consecutive angle parts.

In testimony that I claim the foregoingl asmy invention, I have signed my name in presence of two subscribing: witnesses.
