1 Claim.

This invention relates to racks and more particularly to racks particularly adapted for holding photographic films.

More particularly the invention has reference to racks of the type embodying a movable pressure or rolling weight element that is easily displaceable by the introduction of a sheet into a kerf with which the rack is provided for receiving the sheet, and the return movement of said weight efiects a gripping hold on the sheet to effectively resist a downward movement of the sheet.

The present application is filed in the place and stead of my application filed January 21, 1935, Serial No. 2,810.

The present invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure 1 is a side elevational view of the rack.

Figure 2 is a bottom plan view of the rack.

Figure 3 is a longitudinal sectional View through the rack.

Figure 4 is a detail view taken substantially on the line 4-4 of Figure 3.

Figure 5 is a fragmentary detail sectional view with the rolling weights or balls removed and Figure 6 is a View taken substantially on t .e

line 6-45 of Figure 1.

Referring to the drawings by reference numerals it will be seen that the rack comprises a body I in the form of a substantially solid elongated bar of rectangular cross section.

30 Secured to the top edge of the body bar I is a suspension or attachment plate 9 of suitable material, the latter being secured to the bar 'I through the medium of screws 8.

The bar '5 is provided with a plurality of bores or pockets IQ, of circular cross section, and inclined from the vertical.

The bores I 0 open through the top of the body block I as at I I and at said ends II are closed through the medium of the plate 9 which also 4 serves to retain rolling weights or balls I6 within the pockets or bores I0.

At their lower ends the bores or pockets ID are contracted as at I3 and open through the bottom edge of the body bar 1. Thus adjacent the 5 lower ends thereof the bores I0 are provided with shoulders I2 that serve to limit the downward movement of the balls within the pockets.

Also for each bore or pocket It! the body bar I is provided with a kerf or slot I4 slightly in- 55 clined from a line at right angles to the longitudinal edges of the body bar I in the opposite direction to the bore or pocket I0, Figure 3, and

also extending throughout the thickness of the bar to open at opposite sides of said bar. The said relative arrangement of the bores I0 and kerfs I 4 enables the balls I6 to better hold a thin article such as a film. 5

As clearly shown in Figure 3, the kerfs or slots I4 open at their lower ends into the lower contracted end portions of the bores, and from said lower end portions the kerfs or slots extend upwardly or toward the upper edge of the body 10 bar I at acute angles to the bores I B.

In actual practice the rack is secured to a ceiling, or other similar support through the medium of any suitable securing devices engaging the plate 9 of the rack. 15

For inserting a sheet, for example a sheet I5 of photographic film into one of the slots I l for securing the sheet to the rack, it will be apparent that as an edge of the sheet I5 is inserted into the slot I4 through the lower end thereof 20 said sheet will contact the ball I6 raising the same upwardly a distance sufiicient to permit insertion of the sheet I5 into the slot I l a required distance. When the sheet has attained the required height in the slot It the hand may 2 be released therefrom permitting the sheet to drop down by gravity when the pressure of the ball against the face of the sheet will act toeffectively clamp the latter against the remote side wall of the slot It in such a manner that 30 the sheet will remain suspended.

To remove the sheet from the rack the sheet is first moved upwardly in the direction of the arrow A to loosen the grip of the ball on the sheet, then the sheet is pulled in a lateral direc- 3 tion, or in the direction indicated by the arrow B all of which will be clear from a consideration of Figure 4.

Having thus described the invention, what is claimed as new is: 49

The herein described rack consisting essentially of a ball, and a bar having therein a bore of circular cross section in which the ball is disposed, and also having a kerf extending throughout the thickness of the bar and fully open at opposite sides thereof; the bore being inclined from the vertical and having a lower contracted end open at the underside of the bar and forming in the bore a shoulder to limit downward movement of the ball, and the kerf being 50 straight and open at its lower end to the lower contracted end portion of the bore, and also being extended upwardly from said portion and inclined from the vertical in a direction opposite to the inclination of the bore.
