FINGERPRINT ArPARArUs i Application filed January/1;l 1827,' Serial. `No'.158,9G2.

This invention relates to containers and more.particularly.to holders for retaining a The holders heretofore employed to receive and iixedly maintain a sheet or card for the recording of finger prints have been of an elaborate structure, difficult and expensive to manufacture. In operation, these holders, because of their complexity, easily get out of order and are difhcult to repair. In addition to these disadvantages, these holders involve time consuming methods of operation, for the insertion of the card or sheet and any subsequent change Vof position necessitates an adjustment of the holder. 1

An object of my invention is to provide a holder, inexpensive and easy of construction.

Another object of my invention is to provide a holder that is simple and durable in structure.

Anotherobject of my invention is to provide a holder that is simple in operation.

A still further object of my invention Ais to provide a holder wherein the cards or sheets are securely maintained when desired, yet

permitting movement therein of the recordj ing medium without any adjustment of theV holder.

My invention consists in a device which fiXedly holds the card or sheet when desired and at the same time allows the insertion, withdrawal, or change imposition of the sheet or card without adjustment of the device, and provided with means t0 guidel the card or sheet without positioning the same in the holder.

In the accompanying drawings, in which the same parts have similar numerals:

Figure 1 is a perspective view of the holder containing a card therein;

Fig. 2 is a cross sectional view of the holder along the line 2-2 of Fig. 1;

Fig. 3 is a cross sectional view along the line 3-3 of Fig. 2.

The holder is designed to retain a card or sheet 1 having designated spaces 4c thereon for receiving the impressions of the respective fingers, the holder comprising a block 5 upon twoy perpendicular faces 6 and .7 of which the card or sheet rests. The junction of the two faces 6 and 7 is gradually rounded, as at 8. On the side edges of the block, and eX- tending along both faces are the continuous strips 9, upon which are fastened wider strips 11 overhanginginwardly the'strips 9. fThe strips.v `151 are ,so i spaced from vithe: block that buckling or crumpling of the card or paper is prevented.

While I have shown two strips running the length of the side, it is, of course, obvious that the same result might be obtained by other means, such as one strip with a flange corresponding to the strip 11, or a single strip attached to the block and bent to permit the interposit-ion of a card or sheet between t-he block and the strip. Other strips 12 connect the ends of the side strips. In the drawings the strips 12 are sho-wn as part of the strips 11, but of course they may be separate and attached securely to the side strips.

It will be seen that there is a space 13 between the strips 11 and 12 and the contact faces of the block, permitting the insertion of a card or sheetand its passage through the holder, the strips 9 serving as guides. The strips 12 and the overlapping portions of strips 11 maintain the card or sheet in flat Contact with the block, yet not seriously impecing passage of the sheet over the faces 6, 7 anc 8.

The curvature indicated by 8 provides a j surface over which the recording medium may easily slide. This curved section permits of a complete impression of that portion of the finger desired, whether a so called plain or rolled impression, for there can be effected a longitudinal rolling of the finger in which each segment is impressed on the recording medium. Itis also to be noted that by properly adjusting the sheet there' is prevented any impression of the finger below the desired point on the card.

|The card or sheet, on being forced through the holder, offers resistance to the bending action at 8, and after insertion tends to assume its original flat and straight form. This tendency, however, is prevented by the strips 12, as well as the strips 11. As the card or sheet tends to `resume its normal shape, it is forced against the strips 12, as shown at 14, forming frictional contacts which serve to fixedly maint-ain the sheet in any desired position. y

`While the holder is especially designed for cards on which successive prints are to be longitudinally imposed, it may be used where a card or shcethas space for only one print. And again, while the holder is designed for a card or sheet of a certain width, it does not preclude the use of a recording medium of invention, or exceeding the scope of the apless Width, for the frictional points 14 will securely hold the card in position 'during the printing. A Y Y While I have shown and described the preferred embodiment o-f my invention, I Wish` it tobe understood that I do not confine my self tothe precise details of construction here* in set forth, by Way of illustration, as it isart, Without departing from the spirit of the pended claim.

I claim:

A card holder comprising a block having a horizontal face and a Vertical face, an arcuate surface at the juncture of said faces, a. metal guard mounted upon said block overlying the edges and exposing a. portion of said faces 20 and arcuate surface.

In testimony whereof I aifixrmysignature.
