The accompanying drawing 'illustrates one practical embodiment of the latch device 10 and shows the same mounted on aswingable door 11. The latch device "10 comprises in general. a pair of connected pan and'hous- 2,900,204 Patented Aug. 18, 1959 ice ing members 12 and 13 providing a guideway -14, a bolt 15 movable in the guideway, and a swingable actuating member or handle 116 for causing actuation of the bolt.

The pan member 12 comprises a formed mounting plate having a laterally extending marginal ange 18, and a pan portion 19 rearwardly offset from the plane of `such flange and containing a recess 20. The pan member 12 is here shown as being of a quadrangul-ar plan shape and the pan portion 19 vis likewise of a quad-r rangular plan shape.

The latch device 10 is mounted on the door 1-1 by means of suitable attaching screws 21 which extend through openings Aof the flange v18 `and secure the latter against the front surface 11a of the door. The door is here shown as having a surface opening 23 therein of a lsuitable size and shape, and into or through which, the pan portion 19 projects. Y v

The pan member 12 can be produced by any appropriate equipment and manufacturing operations but is preferably in the form of a sheet metal stamping. lThe marginal ange 18. The pan portion 19 alsohas spaced side walls '25 and spaced end walls 27 and 28. For a purpose which will appear hereinafter,the bottom wallv 24 is provided with a pair of longitudinal slots 29 communicating with the guideway 14 and located adjacent the side walls 25. The pan portion 19 also has a pair of Alaterally aligned holes 31 provided in the side walls 25 at a point spaced from the end wall 27, and a pair of laterallyfaligned locking recesses or holes 32 provided in the side walls 25 at a point which is relatively'more remote from the end wall 27.

The housing member 13 is a hollow member which is applied to the pan portion 19 on therear or exterior side thereof, such that the pan and -housing members are in a nested relation as shown in Figs. 4 and 5 with the' pan portion extending into the recess or pocket of the housing member. substantially at bottom wall 35, a pair of side walls 36, and an end wall 38.A When the housing member 13 and the pan portion 19 -are in the above-mentioned nested relation, the side walls 36 of the housing member embrace the pan portion and lie against the side walls`25 thereof as shown in Fig 4. The lbottom walls 24 and 35 of the pan and housing members 12 and l13 are in a spaced-apart relation such yas to provide therebetween the above-mentioned guideway 14 to 'accommodate the bolt 15.

The housing member 13 is preferably in the form of a sheet metal stamping with the side `and end walls 36 and 38 thereof formed as anges on this member. The end wall 38 is provided with an opening 41 which communicates with one end of the guideway 14. At the other end of the housing member 13, the bottom wall 3S yis provided with a guide lug 42 extending toward the bottom wall 24 of the pan member and which projects into the guideway 14 crosswise thereof. The bottom wall '35 is also provided with -a pair of slots 43 which communicate with the guideway y14 and lie substantially opposite the slots 29 of the pan portion 19.

For use in connecting the pan and housing members 12 and 13, the side walls 36 of the housing member are provided with a pair of laterally aligned holes 44 `spaced from the end wall 38 and, 'at a point more remote from this end wall, are provided with -a of laterally aligned holding progections or embossments 4'5 as ishown in Figs. 4 and 6. These embossments are located on the side walls 36 so as to be engageable in the locking recesses 32 of the side walls of the pan member. The embossments 45 are formed by metal of the side walls 36which The housing member 13. has a has been displaced therefrom by a die operation in the nature of a swaging or shearing operation.

The bolt 15 is here shown as being in the shape of a cross and having a locking portion 15a which projects. from the guideway 14 through the end opening 41 of the housing member 13 and is engageable with a striker plate (not shown) when the door 11'is swung to its closed position.V The bolt 15 also comprises a pair of laterally extending thrust arms`46 and 47 which project from the sidesof bolt in a substantially right-angle relation thereto andlie'between the slots 29 of the pan member 12 and theis'lots 43 'of' the housing member 13. The bolt 15 also includes a forked portion 40 comprising a pair of longitudinal fork arms 48 and 49 which project from the housing member 13 in straddling relation to the guide lug' 42. The fork arms 48 and 49 are separated by a longitudinal slot forming a spring recess 50.

vFrom the construction and arrangement above de- ScribedfOr the bolt 15, it will be seen that this member isslidable in the guideway 14 and is retained therein against lateral shifting, by a guided movement of the bolt projection y15a in the opening 41 and also by the guiding cooperation of the lug 42 with the fork arms 48 and 49. Acompresrsion spring 51 located in the spring recess 50 is effective against theguide lug 42 and against the bolt 15 f'fo r normally urging the latter in a direction to project thevybeolt portion 15a outwardly from the housing member 13.

The handle 16 is preferable in the form of a plate member or` sheet metal stamping having a substantially at plate portion 53 which normally is in a substantially ulsh relation to the top of the marginal flange 18. The handle 16 also comprises a pair of edge flanges 55 carried bythe' plate'portion 53 and extending rearwardly therefrom. Additionally, the handle 16 comprises a pair of actuating projections or fingers 56 formed as integral projections of the edge anges'55.

The handle 16 is located in the recess 20 of the pan portion "`,19 and is swingably fulcrumed on a transverse hinge pin 58 which extends through a pair of aligned holes y60 of the edge anges 55. In its assembled relation" in the pan member 12, the handle 16 is disposed Withfits 'actuating ngers 56 extending through the pairs of slots 29 and 43' and across the guideway 14, as shown inFig.

The fingers 56 are engaged by the thrust arms- 46 and 47 f of the bolt 15 and, during swinging of the handle outwardlyyofthe recess 20 of the pan member 19, the fingers 'impart a retracting movement to the bolt and causefmoveme'nt thereof inwardly of the guideway 14 in opposition' to the spring 5. When the handle 16 is released, the spring 51 will impart an outward movement to the bolt which, in turn, will cause an inward swinging movement of the handle to its normally flush position shown in Fig. 5. The return swinging movement of the handle is limited by the engagement of the straight back edges," 62 of the iingers S6 with the transverse end walls 63'of the slots 43 for locating the plate portion 53 of the handle in the above-mentioned substantially ush relation to the marginal flange 18.

lAs 'shown in the drawings, the handle 16 is relatively shorter than the pan portion 19 so as to leave an accessV passager'64 lfor the insertion of the operators iinger, or fingers, beneath the plate portion 53 for imparting outward swinging movement to the handle. At the free end of the handle the plate portion 53 thereof is preferably provided with a curved edge portion or flange 65 for the comfort of the operator in applying actuating thrust tol the handle. At the hinged end of the handle the plate portion 53 4is provided with a curved reinforcing weby portion 66 which extends transversely between the edge anges 54 and 55.

Oneof the features Vof thepresent invention resides in therattachment of 4the housing member 13 to the pan member,4 12, and also concerns the assembly operation by which these members are assembled and connected in the above-mentioned nested relation. ln assembling the parts of the latch device 10 the bolt 15 and the spring 51 are placed in the housing member 13, after which this member is applied to the pan portion y19 from the rear side thereof causing the holes 44 of the side walls 36 housing member to become aligned with the holes 31 of the side walls 25 of the pan portion 19, and to also cause the embossments 45 of the housing member to engage in the locking recesses 32 of the pan member with a snap engagement therein.

The handle 16 is then inserted into the recess 20 with the actuating fingers 56 and 57 extending crosswise of the guideway 14 through the pairs of slots 29 and 43 and with the holes 60 of the edge anges 55 of the handle in alignment with the previously aligned holes of the pan and housing members. The hinge pin 58 is then inserted through the aligned holes to form a fulcrum for the handle 16 and to assist the embossments 45 in retaining the housing member 13 in its fully assembled position on the pan member 12.

The hinge pin 58 can be any suitable pin having a headV When the major components of the latch device 10 are. constructed and assembled in the manner above-described,`

they can be of a relatively simple form and can be rapidly and economically produced as sheet metal stampings. ing members 12 and 13 are connected by means of the hingel pin 58 and the embossments 45, no elaborate assembly apparatus is needed and, moreover, no welding operations need be performed for holding the parts in a connected relation. The elimination of such welding operationsis advantageous because the marring and discoloration usually resulting from such welding operations is avoided, such that the components of the latch device 10 vc an be provided with the desired ornamental nish during the production thereof and will remain in an unblemished condition in the assembled device.

If desired, a key-actuated locking means can be provided for the latch device 10, and is here shown as cornprising a support sleeve 72 having a lock barrel 73 rotatable therein and carrying a locking aim 74. The support sleeve 72 is located adjacent the latch device 10 and is secured in an opening of the door 11 by a clamping nut 75. The barrel 73 is of the cylinder lock type and is rotatable in the sleeve 72 by means of a key 76 inserted into the barrel.

The locking arm 74 is secured to the rear end of the barrel 73 and is swingable by the latter to locate its free end 77 in a substantially abutting relation to the rear end of the forked portion 40 of the bolt 15. When the locking arm 74 is in this aligned relation, retraction of the bolt 15 will be prevented, but when the locking arm is swung to ,its unlocking position 74a of Fig. 2 by means of the key 76, the bolt will be free for retracting movement by the handle 16.

Although this novel latch device has been illustratedV and :described herein to a somewhat detailed extent it willbe understood, of course, that the invention is not to be regarded as being limited correspondingly in scope but includes all changes and modications coming within the terms of the claims hereof.
