arm's.- (01.292-Q-1169l i corporation with the closure member such as the door or drawer.

Another object of this invention is to provide a device ofthe character mentioned above, in

I generallylto hardware 3 1 is integrally secured to the inward or reverse side of an escutcheon 'platez' l2 havingaperture"" which the rollback and a shoulder on a shank portion of the door pull are used, in combination with other parts, to retain the'door pull within the assembly, while allowing rotation-of the-door pull so as to actuate the latchm'echw.

Anotherobject of this invention is to provide a device of the character 'mentipned i'above, in

which .the escutch'eonpI-ate andIthe main;casing' v for the latchmechanism are formed integral with 7 each other and the door pull and escutcheon plate are so formed that the fingers of a person operating the closure'member may bereadily 1nserted behind the handle portions of the door pull, all without necessitating the protrusion of the door pull any great distance in front of the escutcheon plate, the advantages of this construction, from the viewpoint of easy cleaning and safety as well as from the esthetic viewpoint, being obvious and important.

And the last object to be mentioned specifical- 1y is to provide a device of this character which is generally adapted for mass production, which is relatively inexpensive and practicable to manufacture accordin to accepted manufacturing procedures, which is simple, safe and convenient to use, and which will give generally eflicient and durable service.

With these objects definitely in view, this invention resides in certain novel features of construction, combination and arrangement of elements and portions as will be herein-after described in detail in the specification, particularly pointed outin the appended claims, and illustrated in, the accompanyingdrawings, in which:

Figure I is an exploded view showing the parts of this invention in perspective;

Figure 2 is a frontelevational view of the as- I sembled device; 1 t

Figure 3 is a vertical sectional view, taken sub- Figure :4 is a horizontal sectional view taken substantially upon the sectionline 4+4 in; Fi

Similar characters of reference designate similar or identical elements and portions throughout the specification and throughout the differentviewsinthedrawings: s Referring nowto the drawings in detail, this device includes a casing l0-'which-"has' the general configuration of a hollow cylinder and which II for reception lbf escutcheoni: mte attaching screws l 6. I It should? :be :-noted' that the escutch= eon plate I2 is recessedor:dishedasindicated'at J58, and. this ,es'cutcheon1platetwillordinarilybe secured by the screws [6 within a suitable opening in a closure member ;20 such as a hinged door, front Netti-cal panel ,ofla sliding-drawer, or" the like; The plate l2 has a central boss which may be considered as extendingwithinthe recess 18; and this boss;2 2; is axially bored at 24 toprovide abearingifor thesh-anklportion 26 of the sub stantially T-shapedidopr pull generally indicated lay-the; numeral 28.5 Therdoor' pull 28"has'a shoulder 30 which frictionally abuts the boss 22 to limit the movement of the door pull in one direction relative to the assembled device, and

the door pull also has a pair of diametrically disposed handles or grips 32 which are recessed as at 34 on the sides thereof adjacent to the es- It should be carefully noted' cutcheon plate 12. that the recess l8 and the recessed portions 34 of the door pull are opposite each other and that this construction allows the grips to reoede into the "well thus provided and also allows the entrance of the fingers of a person operating the v closure member 20, so that the turning of the door pull to unla-tch the device, and the use (if the door pull as such, is greatly facilitated, without the necessity of having the door pull project any great distance beyond the front of the escutcheon plate.

The end of the shank 2B remote from the handles 32 is squared as indicated at 36 to receive a, rollback 38 having a square aperture therein and a cotter key 40 orthe like is inserted through the squared portion 36 to hold the rollback in position and to prevent the shifting of the door pull axially of theassembled device when tension is placed by a persons fingers on this door pull. This simple construction also involves the provision of a bifurcated portion 42 on the bolt 44, it being understood that this bifurcated portion 42 frictiqnally abuts what may be considered the rear face of the escutcheon plat 12 andthe bolt 44 is received and guided by the opposing ends of the casing l where this casing is divided as indicated at 48, as clearly shown in Figure 1, it being also understood that the bifurcated portion 42 will straddle the shank 26 so that the bolt is prevented from movement xcept in one plane. The bifurcated portion 42 terminates in a pair of lugs 48 which ar engaged by the extending portions 50 of the rollback 38, according to well understood and conventional practice.

A rear plate 52 is secured by means of screws 54 to cover the end of the casing l0 remote from the escutcheon plate I2. Finally, a post 56, preferably integral with the escutcheon plate l2 extends in an axial direction but eccentrically of the casing I0 and is used to secure a spring 58 in position with its ends engaging a portion of the casing l0 and one of the lugs 48 on the bolt, so as to bias the bolt in one direction against the action of the rollback 38 when the latter is rotated by the door pull 28. It is thought unnecessary to further describe the action of this spring since such construction-s are conventional.

The operation of this invention will be clearly understood from a consideration of the foregoing description, of the mechanical details thereof, taken in connection with the drawings and with the above recited objects of this invention. The drawings and specification are proposed as illustrative rather than limiting and minor variations from the embodiment described may be resorted to without departure from the spirit and scope of this invention.

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

1. For use in the construction of a combination catch and drawer pull, an escutcheon plate having a central recessed portion with a central bearing projecting in the recess, an outstanding marginal attaching flange carried by the wall or the recessed portion and an annulus carried by and projecting laterally away from the-bottom of said recessed portion, a cover for said rotatively mounted on and having a shank extending through said plate into said casing, a

bolt slidably mounted for operation in said casing, spring means cooperating with and biasing the bolt in one direction, means operatively connecting said bolt with said shank, said door pull having a shoulder engaging a portion oi said escutcheon plate to prevent axial movement of the door pull in the opposite direction, said door pull havin diametrically disposed handles provided with recesses on the sides thereof adjacent to said plate, said ,last mentioned portion being a central boss and said escutcheon plate having an annular recess opposite to the recesses in the handles to facilitate entrance of a person's fingers behind said handles, said escutcheon plate having walls dimensioned to span a door panel whereon the device is used so that said casing is supported by said escutcheon plate and disposed on the side of the panel remote from said door pull.
