A left handed person will usually use two, hands-one to unlatch the latch-and the other to pull out the drawer.

With these considerations in mind, it is an object of my invention to provide a drawer pull construction having all the advantages of structures lrnown heretofore, while eliminating objecdons meniien a It is an ct r my nvention to p e a wer ul h ng a triecar l tch with the confines or the awer 1,111,, so that an unbalanced or unsymmetrical appearance of the drawer face is avoided. It is another object of my invention to proyide a construqtigu, whereby a person grasping the drawer pull with either hand will automatically engage the trigger latch, so that the drawer may be opened as readily by a left handed person, as by a right handed person.

It is a further object of my invention to provide a structure as outlined above, which will not require extensive redesign of present latch mechanism and which will not add substantially to the cost of production.

My invention may be applied to the drawers ofany conventional file cabinet, such as the one illustrated at 10 in Figs. 1 and 2. The particularcabinet illustrated, has'four drawers ll, each eiwhich is provided with a pull l2. It is' conven tional in such cabinets to provide, usually in the".

left side wall of the cabinet, struck out tongues- I3 which constitute a latching abutment, audit is also conventional to provide on the baclcoi the drawer face, or within the drawer facaif it is a doubled walled structure, a siidablem'embenll having a latch element [5 and springurged toward the left of Fig. 4. With this structure,

the drawer being opened, closing movement of 4.0 the drawer causes-the latch member to move toward the right of" Fig. 4 as it rides up the-latching abutment i3, until when the drawer is closed, it snaps 'baclg behind the abutment [3 to latch he drawe Instead o Prcvidiae a b uq at s me point, as for example; indicated at l6 in Fig. 4,- for retracting the latch member I5, I provide a trigger member mounted on the drawer pull and disposed within the confines of the drawer pull, as will now be described in more detail.

The drawer pull l2 may be of any desired construction, but will usually be generally C-shaped and will have threaded holes I! by means of which it may be fastened to the drawer face. On the 3 inside of the arm l2a of the drawer pull I2, I provide a T-slot I8.

The trigger member which I prefer to use is shown in more detail in Figs. 6 and 7 and comprises a bellcrank element indicated generally at I9, and having intermediate its ends, pintles 20 and 2|. If the trigger member I9 is adie casting, the members 20 and 2| may constitute a single transverse shaft like extension, as best seen in Fig. 7.

One arm of the member I9 is curved as at 22 to constitute a trigger finger, and the other arm at 23 is simply a straight extension of any desired configuration. The curved trigger finger 22 merges into an extension 24, the purpose of which will be pointed out hereinafter.

In assembly, the trigger member I9 is assembled to the drawer pull l2 with the pintles 20 and 2| riding in the T-slot l I and with the trigger finger 22 extending within the confines of drawer pull I2. The front wall IIa of the drawer face will have'perforations for the passage of fastening screws 25 and 23, by means of which the drawer pull is fastened to the drawer face. At the right hand side of Fig. 3,the rear wall III) of the drawer face may be provided with a stamped depre'ssion 25a to provide a spacer between the walls ll'a and lib. At the left hand side however, it is not desirable to form a depression to constitute a spacer and therefore the screw 26 will have a larger unthreaded portion 21, which will constitute the spacer. The wall IIa will also have an aperture Ilc for the passage of the member 23, and because the trigger member must have pivotal movement, the aperture I I will have to be larger than the member 23.

The purpose of the extension 24 will now be apparent. This extension is of such extent that when the trigger member is in the position of Fig. 8, it covers the aperture 0, which would otherwise be unsightly. The abutment 24 also serves to limit the movement, in a counterclockwise direction, of the trigger member.

Means must be provided for connecting the member 23 with the latch and these means may be of any desired form. I have shown for example, an extension I4a of the latch I4 provided with a slot Mb to accommodate the screw 21 and the member 23. The inner wall I lb of the drawer face may be provided with a struck down ear I Id and a compression spring 30 may be interposed between the ear Hat and the shoulder I4c of the member I4.

. From the foregoing description, the operation of. the device will be clear. When it is desired to open the drawer, either the right or left hand may grasp the drawer pull I2. With a right handed person, the index finger will normally come behind the trigger finger 22, and with a left handed person, the fourth finger will normally occupy that position. Upon pulling on the drawer pull, it will be natural to exert a small amount of tension either with the fourth or index finger on the trigger finger 22 which will cause themember 19 to rock in a counterclockwise direction about its pivot at 20, which in turn will pull the member I4 to the right against the compression of the spring 30, freeing the latch I5 from the abutment I3.

The drawer is closed in the usual manner and the latch operates in closing, just like any conventional present day latch.

It will bev clear that numerous modifications may be made without departing from the spirit of my invention, and I therefore do not intend to limit myself otherwise than as pointed out in the claims which follow.

Having now fully described my invention, what I claim as new and desire to secure by Letters Patent is: p

1. A drawer pull for use in a drawer having a latch which is normally spring urged to closed position, said pull having a gripping member spaced from the front of said drawer and an attaching member for securing said gripping member to'the front of said drawer, a T-slot in said attaching member, a trigger member having pintles mounted on'said pull with said pintles seated in said T-slot, said trigger member having a trigger finger extending within the confines of said pull, and means connecting said trigger with said'latch.

2. A drawer pull for use in a drawer having a latch which is normally spring urged to closed position, said pull having a gripping member spaced from the front of said drawer and an attaching member for securing said gripping member to the front of said drawer, a T-slot in said attaching member, an operating member comprising a bell crank having pintles intermediate its end and one arm of said bell crank constituting a trigger member, said operating member being mounted with said pintles engaged in said T-slot with said trigger member extending within the REFERENCES CITED The following references are of record in the file of this patent:
