ALBERT BENDER, OF MCKEESPORT, PENNSYLVANIA.

STRETCHING AND DRYING FRAME.

Specification of Letters Patent.

Patented Feb. 21,1911.

To all whom it may concern:

Be it known that I, ALBERT BENDER, a citizen of the United States of America, residing at McKeesport, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Stretching and Drying Frames, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a stretching and drying frame especially designed for the use of photographers in drying paper during the various steps of producing a photograph, either in the preparation of the sensitized paper or in the treatment of the sensitized paper after it has been exposed or received the imprint.

The object of my invention is to provide a drying frame with positive and reliable means for holding and stretching a piece of paper placed thereon, and with means for absorbing moisture in the paper, the stretching means preventing the paper from shrinking or becoming distorted while the moisture thereof is absorbed or dried, thus preventing the imprint upon the paper from being drawn out of proportion.

I attain the above object by a frame that is extremely simple in construction, durable and highly efiicient for the purposes for which it is intended.

The invention will be hereinafter specifically described and then claimed, and refer ence will now be had to the drawing forming a part of this specification, wherein Figure 1 is a plan of a frame in accordance with this invention, Fig. 2 is a view of the edge of the same, and Fig. 3 is a cross sectional view of the frame on line 00-41; Fig. 1.

In the accompanying drawing the reference numeral 1 denotes a rectangular board and securedto the bottom of said board are two cleats 2, these cleats being arranged transversely of the board adjacent to the ends thereof. The cleats 2 and the board 1 are provided with vertical openings 3 for the shanks 4. of pegs or legs 5 adapted to support the board in an elevated position above a table or other support. The board 1 has the top 1 thereof at two sides provided with equally spaced vertical pins 6 and the edges of the board at the opposite sides from the pins 6 are provided with equally spaced outwardly extending pins 7. These pins have projecting pointed ends and the opposite ends can be either driven or screwed into the board 1 or otherwise mounted therein. The

pins constitute a rectangular frame for holding a piece of cheese-cloth or other absorbent material 8, the cloth having two edges thereof mounted over the pins 6, while the other edges of the cloth are held by the pins 7 after the cloth has been stretched upon the the other edges thereof placed in engagement with the pins 7, whereby the paper will be retained in a stretched position while being dried. In some instances, it is not necessary to place the paper in engagement with the pins, but simply place the same upon the cheese-cloth whereby the cloth will absorb part of the moisture of the paper while the remalnder 1s belng dried by the sun or suitable source of heat.

From the foregoing it will be observed that I have devised a novel frame or board upon which paper can be easily stretched and dried, the frame or board obviating the necessity of using ferrotype tin at present used by photographers in drying sensitized paper after it has been exposed and treated with the various solutions for developing the imprint upon the paper.

What I claim is 1. A frame for the purpose set forth comprising a board, a row of vertically disposed pins projecting from the upper face of said board in proximity to one side ed e thereof, a row of vertically disposed pins projecting from the upper face of said board in 9 proximity to one end edge thereof, pins proj ecting from the other end and side edges of the board and disposed at right angles with respect to the said rows of pins, and a piece of absorbent material stretched upon the vertical and right angularly disposed pins.

2. A frame for the purpose set forth comprising a board, a row of vertically disposed pins projecting from the upper face of said board in proximity to one side edge thereof,

a row of vertically disposed pins projecting from the upper face of said board in proximity to one end edge thereof, pins projecting from the other end and side edges of the board and disposed at right angles with respect to the said rows of pins, a-piece of abengaging in said openings, said legs abutsorbent material stretched upon the vertical ting said cleats. 10 and right angularly disposed pins, a pair of In testimony whereof I affix my signature cleats secured to the lower face of said board in the presence of two witnesses.
