CATCH FOR FILE-CABINETS.

SPECIFICATION forming part of -Letters Patent No. 433,997, dated August 12, 1890.

Application led March 13, 1890.

To all whom t may concern.-

Be it known that I, WILFRED I. OHMER, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Catches for File-Cabinets,of which the following is a specification, reference being had thereinto the accompanying drawings.

My invention relates to certain new and useful improvements in gravity pawls for sliding doors of iilecasesllIyiinprovements have reference to combining a lift attached to a sliding door with a gravity-pawl formed in one piece. They also have reference to combining a frame secured to a sliding door and adapted to receive a designating-card and havingalift integral thereon, and also having lugs on the frame which carry a gravity-pawl having a downward extension to engage a portion of the case and support the sliding door, and having also a spur proj ect-ing outside to manipulate said pawl, and have reference to other points of detail hereinafter brought out and explained.

In the accompanying drawings, forming a part of this specification, and on which like reference-letters indicate corresponding parts, Figure l represents a front elevation of my device; Fig. 2, a rear view thereof; and Fig. 3, a vertical section on the line x 0c of Fig. 2, showing its relation to a tile-case, also in section.

The letter A designates a file-case having a sliding door B, to which is fastened by screws or otherwise a frame O, adapted to hold and expose to view a card designating the contents of one division ofthe said case and preferably inserted in the said frame by sliding into a recessed portion therein, that secures it by the edges, as shown in Figs. 2 and 3. This frame has a lift D, projecting therefrom and formed integrally with the same, extending, preferably, from the lower` portion of the frame, as shown, and used for raising the said sliding door by catching the finger under it in the usual way. Directly above the lift, and preferably on the rear side of the said frame, is pivotally mounted on axle carried by ears or lugs e e or otherwise a pawl E,hav

the said lift.

broadened to give a good bearing-surface and enlarged to preserve a normally vertical position 4by the weight thereof. An opening or slot G in the said frame allows a projection of spur II on the upper part' of the said pawl to project through the said slot and extend conveniently over the said lift. The size of the said spur is not so great as to overbalance the downward portion F,which thus normally sustains it in an elevated position at the upper end of the said slot and in convenient reach of the thumb when the finger is under or let into the door, so that the shelves of the.

ycase may be in close proximity to the doors and yet be clear of any accidental engagement with the pawl. Thus only the compartment opened is exposed to the entrance of dust during the temporary opening of the same.

The action of the device is as follows: The forefinger is placed under the lift and the sliding door is raised till the bottom of the extension F is higher than the next shelf above thc compartment or compartments to be opened. down upon the spur II, causing the said eX- tension of the pawl to tly upward and inward. The door is lowered till the pawl bears on the shelf, and thus holds the door up after the hand is removed. The spur H is then in its lowest position and bears against the bottom of the slot and forms a stop for the pawl. One or more doors may be supported by the pawl that is in action when used in a series of vertically-sliding doors, all in the same plane, and in this case only the pawl of the lowest compartment open is actuated by the thumb, while all the others preserve their normal position away from the shelves, due to gravity. lVhen the door is to be lowered, all that is necessary is to. raise the door by the lift, so that the pawl can drop into its recess and out of engagement with the shelf it was bearing upon and then lower the door to its proper position, thus closing the compartment. In the case of a series of doors resting upon the one whose pawl is actuated, the release -of this pawl will allow all the other doors to descend also. Thus it will be observed that by one simple action of the thumb ou the pawl of The pawl is preferably recessed The thumb is then pressed lightly IOO the door lifted the door is held in the desired elevated position by the pawl thereof, which automatically disengages itself by the action of gravity when the door is raised slightly and then lowered to its closed position without any action of the thumb in the whole operation, except a slight downward pressure on the spur of the pawl to cause the extension F to iiy upward and inward in order to engage the shelf.

'I/Vhile I have described my device as ap plied to the sliding door of a tile-case, I do not wish to be understood as limiting` myself to this particular form or construction.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

Il. In a tile-cabinet, thc combination,witha sliding door and an adjacent portion of the case, of a gravity-pawl having a downward extension and a projecting spur formed in one piece and pivoted in the said door so as to engage the said adjacent portion and support the said door.-

2. In a tle-cabinet,the combination, with a sliding door and an adjacent portion of the said caseot` a pivoted gravity-pawl having a downward extension to bear upon the said adjacent portion when raised by a spur that normally occupies an elevated position on the said pawl, and means to secure said pawl in its pivotal position in said door.

3. In a iile-cabinet,t11e combination, with a sliding door and an adjacent portion of the case, of a frame adapted to hold a card and having a lift formed integrally thereon, and also having a slot in the frame near said lift, and a gravity-pawl in one piece pivoted in the said slot and adapted to engage said portion of the case and support the said door.

. L1. In a tile-cabinet, the combination,with a sliding door, of a frame adapted to hold and expose a card and havinga lift formed integrally thereon, and also having ears, and a gravity-pawl pivoted between the said ears and having a downward extension to support the door and also an upward spur projecting outside of the frame to manipulate said pawl.

5. In a catch, the co1nbination,with a frame adapted to hold and expose a card and having lugs to form pivot-supports, of a pawl pivoted between said lugs and having a gravitating end to engage a fixed object and a normally-elevated end adapted to bein ani pulated by the hand.

6. As a new article of manufacture, a lift for doors, consisting of a single piece of metal provided with an index display-opening and a pawl pivoted thereto.

In testimony whereof I afx my signature in presence of two witnesses.
