To all whom it may concern. 7

Be it known that I, ERNnsT J. MARTIN, a citizen of the United States, and a resident of New Rochelle, in the county of VVestches ter and State of New York, have invented new and useful Improvements in Artist-s Frames, of which the following is a full, clear, and exact description.

This invention relates'to artistsframes,

and was primarily designed for use by scenic artists.

One of the diiticultiesthat often confront scenic artists is how to support a flexible paint receiving foundation of large dimensions in a room of comparatively small-"di-I niensions, thus eliminating the necessity of providing a building of suiiicient" size to house the paint receiving foundations of the greatest size that they may be requiredto operate upon in the carrying on of their work. Once such a problem has been solved it is possible for the scenic artists to carry on work on all sizes of paint receiving foundations without making a large outlay to provide a building of sufficient size to' accommodate all sizes of foundations that he may find it necessary to work upon. The general object of'this invention'is the provision of anarti'sts frame for sup: porting flexible paint receiving foundations of dimensions several times that of the cross section of the building or room in which it is desired to work. f'

A further object is the provision of an artists frame capable of adjustment to -accommodate various sizes of paint receiving foundations; 7 g 7. Another object'fis the provision of an artists frame whichsupports the painting face in such a position thatfit slopesaWay from the vertical towards the bottom. 'This object is accomplishedby providing roller supporting means spaced in triangu- 7 lar relation for supporting the paint receiving foundation and providing means inconjunction with the roller'supplorting means for varying the distance between any two of the-rollers so as to accommo'daate paintfl receiving foundations of difl eren't sizes and so locating two of the rollersthat a'portion of the paint receiving'fou'ndation is re: tained in a positionfl'slopin'g away from the vertical towards" the bottom. i

These and other objectsof the invention will-be -'moreclearly understood from the following detailed description and accompanying drawings, of which Figure 1' is a side-elevation of the artists frame with. a paint receiving foundation mounted thereon; I

Figure 2 is frame; Figure 3 is a Figure 4; and j t Figure -4 is a section alongthe line 44', Figure 2. y j

Referring to the above-mentioned draw ings, tWo end supporting posts 10 and 11 areshown attached to the ceiling 12 and section along'the line 3+8,

floor 13 of any room or building in which the framemay be located, and a'center supporting post 14 carried by means of

braces

15, 16, 17 and 18 is attached to the endsupporting posts 1.0 and 11. Each of the posts 10, 11 and 14, have two brackets 19 and '20 attached thereto Which-are providedwvith bearings in which the's'

hafts

21 and 22 are mounted respectively. A curved arm 23 provided with a trunnion 24 is provided in conjunction with? each post and supported on each post by means of abracket 25 which has a slot 26 cut therein inIPwhich the trunnion 24 moves. -Ashaft27 is journaled in these arms. A rod 28 is slidably mounted in

guides

29 and 30 mounted on each post, and the upper-end of each rod 28 is connected to the curved arm 23 mounted on the corresponding post! Each rod 28 is operated by means of a connecting rod 31 and a bell crank 32" which-is fixed'to a shaft 33 j ournaled in' brackets 34 carried by the posts.- A gear 35 is mounted on the-shaft an end elevation of the'artists 33 and is operated by means of aworm gear 36 mounted on the post 10. This Worm gear is operated by means of a crank 37;

In this particular construction, as shown in Figure '4, two rollers 38 are] loosely mounted'on each shaft; These rollers are provided with grooves 39 in which 'belts 4O are located. These belts 40 are rovided with projection 41 which'engage t ejpaint receiving" foundation 42 mounted upon-the rollers so as to prevent the-(said paint receiving foundation from slipping thereon;

Provided in the rollers 38 n lQ untedvon the 105.

shaft 21 are chambers 43 and I Located in each chamber and fixedto the shaft are collars-45 "and 46 provided with 'pins 47-. and 48, respectively,"Thesepins .47 and 48"en- V age'in'openings provided in the disks 5].

supported on the post 10 by means of bracket 54; and-pin 55.

r A U-shaped portion 56 of the lever 53 engages a spoolshaped collar 57 fixed to the shaft 21, serving as a means for moving the shaft 21 endwise. The pins greater length than-the pins 4 8 and so by the movement of" the shaft either one'or .tworollers may be connected to the shaft so as to drive them upon the operation of the shaft. A grooved wheel 58 'is fined to each end of each shaft 21-, 22 and 27 and a belt 59 extends around the wheels. 58 locatedat each endofgthe frame. These -wheels'58 and the belts 59 serve as a means for operatingthe shaft and, through the shafts and connecting devices mounted on the shaft 21 the rollers Four plates. are provided with. a plurality of hooks (52 and eye members 63.

These olates serve t en ane the on aosit l a i. 3

ends of thelpaint:receiving foundation 4.2,

er a lacing .61, is supplied forfattaching the eye members of the different plates 60 so as to connect the opposite ends of the. paint receivin foundation 12- in order. to hold the Zh r latter in position upon the. rollers 38.

In order to give considerable rigidity J to. the center post 14, the braces-15 and 18 support the post through a cross arm (it which is fined to the post. Turnbuckles are connected into the braces 15 {1018, inclusive, so that. they. maybeadjusted to. bring the center bearings. supported-by the center post 14 into al-inement with the other bearmga V e In using this frame the rollers 38 carried by. the shaft27 are moved.- to what is decidedto be the proper distance, from the rollers 38carriedby the. shaft 21 so that the perimeter. about all the rollers will be slightly greater than the length of the paint receiving foundation. The lever 53 isthen operated connecting the, rollers 38 on the shaft 21 to the shaft. The. paintreceiving foundation is then engaged with the pro jections. 41 on the belts a0 I and woundabout therollers. The, hooks of the plates 60 are engaged in thej'opposite ends. Ofthe paint receiving; foundation, and: the eye members are connected together. by means of the laclZ-his. holds. the paint receiving foundation in position on the rollers. The

lever. 58,;is: then; eperatede, 'moving the shaft gl asseen inhiguregtftqthe left, engaging the ins. 4;7;.anrl 48 inthe disks. 51 and. 52,

' thusconnectingthe rollers to/theshaft.

After this. connecting(operation has been completed" the rollers may. be? operated by operating-the. belt- 59' to move the. paint re:-

. eeiving; foundation; to. any desiredposition.

47' as shown are of After the paint receiving foundation has been stretched upon therollers the, crank 3? might be operated to move; the shaft 2? outwards so as to tension the paint receiving foundation 42. The operation of the mechanism" for controllingthe position of the shaft 27 is as follows: The worm gear 36 is operated by means of the crank 37, rotating the gear, 35 andthrough it the shaft 33. This rotates the arms 32 towards a vertical position, forcing the ro1ds28 upward, mov: ing the arms 23 outward thus shaft 27 from the shaft 21.

The

shafts

21 and 22 are so positioned with regard to the frame that the portion of the paint receiving foundation extending between them falls away from the vertical towards the bottom. The advantage of such a construction is that when drops of paint fall from thehrush while the painting op; eration is carried on there is nodanger of it coming in contact with the paint receiv ing foundation EDI streak the same.

It will be seen fromthe foregoing description that the shaftQl may. be connected 1: to one, ormore of the rollers mounted thereon. This. allows the'frame to be usedfor paint receiving foundations which are small.

A smaller paint receiving foundation extends over. the rollers placed; triangular relation to one another, and by connecting one rollerto. the shaft 21'? all the rollers are driven through the belt means59. The belts which are located on. the rollers38 are ad: justahle sons to allow the

shafts

27 and 21 lee to be set with different distances between.

ing. fieXiblepaint; receiving mediums comprising. supporting. members, three. lines of rollers. spaced in triangular. relation. to one another carriedby: the supporting. members,

one line of said-rollers being-. mounted.on

arc-shaped plates carried-by the supporting members, and means. for adjusting said are?- shaped plates-to increase the distance be.- tween two. of the lines of rollers toaccoinmodate different sized paintreceivingmediums.
