PHoTocRAPHlc-PRINT HOLDER.

' SPECIFICATION forming' part of Letters Patent N0. 627,069, dated June 13, 1899.

Application filed November 10l 1898. Serial No. 696,039. "No mndel To all whom, it may concern:

Be it known thatl, JOHN G. BAKER, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements iny Photograph-Print Holders, of which the following is a specification.

The object of my invention is to provide a simple and efficient device whereby a photograph-print may be securely retained while paste is being applied to the back of the same, all risk of soiling the face of the print being avoided.

In the accompanying drawings, Figure 1 is a plan View of a photograph-print retainer constructed in accordance with my invention. Fig. 2 is a transverse section of the same on the line .r an, Fig. l; and Fig. 3 is a sectional View illustrating a modification of the invention.

The holder comprises two blocks l and 2, the latter block being placed upon the top of the block l and secured thereto in any available manner. Distributedthroughout the area of the block 2 are a series of vertical openings 3, and in line with the central opening 3 of said block there is in the base-block 1 an opening 4, with which communicates a lateral passage 5, having at the outer end a vprojecting pipe 6, to which is applied the end of a rubber or other flexible tube 7. The other end of this tube may be placed in the mouth, so as to exhaust the' air from the tube and from the openings with which it communicates, or the air may be exhausted by a pump or otheravailable device. All of the openings 3 are in communication with the central opening through suitable passages 8, formed either in the under side of the block 2y or in the upper side of the block l, so tha when the tops of the openings 3 are closed by means of va photograph-print laid upon the top of the block 2 land air is exhausted from the tube 7 a partial vacuum will be created in each of the openings 3. Hence the print will be confined to the face of the block 2 by atmospheric pressure at as many diterent points as there are openings 3 formed in said block, and while it is thus iirnily retained paste can kbe applied to the back of the print without any risk of moving the same from its proper'position, the release of the print bef ing effected as soon as air is again permitted to enter the openings 3, so that the print can be lifted by means of the paste-brush and at once applied to the card or other surface to which'it is to be attached. Both the pasting and the subsequent handling of the pasted print are thus eifected without touching the same with the lingers, thereby overcoming an objection to present methods of pasting' photograph-prints having highly-glazed surfaces, snce contact of a moist or pasty finger with such highly-glazed surface destroys its polish and results ina soiled print.

The block 2 is by preference of slightly less dimensions than the print 9, as shown in Fig. 2, so that the edges of the print slightly overlap the edges of the block, and thereby prevent any application of paste to the top of the block, which would result in the soiling of the next print.

In order to providea surface which will prevent the horizontal slipping of the paper print on the face of the block, cushions of rubber or other elastic material surrounding each of the openings 3 may be employed. In the construction shown in Figs. l and 2 these cushions are in the form of rings 10, let into countersinks formed in the face of the block around each of the openings 3, although, if

desired, a sheet of rubber or equivalent material may cover the entire face of the block, as shown, for instance,- at 1l in Fig. 3, or the face of the block may be coated with rubber, cement, or equivalent material, which when dry will provide a bed over which the print when subjected to atmospheric pressure will not slide.

Having thus described my invention, `I claim and desire to secure by Letters Patent- 1. A photograph-print holder consisting ot' a block of rigid material having distributed throughout its area a series of openings communicating with each other and with an air exhausting pipe, each of said openings being surrounded at the face of the block by elastic material over which the print, when sub? jectcd to atmospheric pressure,will not slide, substantially as specified.

2. A photograph-print holder consisting of a block having distributed throughout its area a series of openings communicating with each other and with au air-exhausting pipe, each ICO of said openings being conntersunk at the top and having let into said countersunk portion an annular cushion of material over which the print-when subjected to atmospheric pressnre,.w,i1l not slide, substantially es specified.

3. A photograph-print holder consisting of a two-part block, the upper portion having openings distributed throughout its area `amd the lower portion having an opening commu- .ro nicating with one of the openings in theA top block,-and with an air-exheusting pipe and having channels or passages between the blocks whereby all of the openings may com'-4 muncate with the opening in the base-block, substantially as specified. l

In testimonyT whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

JOHN G. BAKER. Witnesses:

WILL. A. BARR, Jos. H. KLEIN.-
