. so that'itV cannot be accidentally displaced.

the front side ofplate IU. j Preferably formed on the opposite sides ofstuds I5 and I5 are pairs of slots I9` and 20 respectively, these slots being spaced from end portions I'Sa and |3b thus being immediately above the rear surface of the plate v I when the parts are in the position shown in Figure 2. Y c

Turning'to Figure 4, thereis shown a fasten# ing Vpart generally indicated at 2|. Part 2| is preferably channel Vshaped thus having a pair of flanges 22 and Y23 upon its opposite sides.y

Formed in the base portion ofjpart2| are two bottle shaped apertures generally indicated at 24 and 25. Thus apertures 24 and 25 comprise large portions 24a and 25a and neck:portions 24h and 25D. The upper portion of part 2| as viewed in Figure 4, is narrower than the main body portion thereof thus to allow these `portions 23a and 22a of flanges 2'2 and 23 to extend away `fromthe .base thereof a greater distance than do flanges 22 and 23 forthe greater-part of their-length. Y

Accordinglypwhen.assembling this lock plate construction, handle I3 is placed in the position shown in Figure 2 so that studs I5 and I6 extend through apertures '|'I and I8 andend portions |3a and |32) lie flush against thel front face of plate III. Next, fastening part 2| is placed over? the studs so that the studs extend through portions '24a and 25a of apertures 24 and 25. Now when fasteningpart 2| is forcedvdownwardly, as viewed in Figure 2, neck portions 24h and 25h of apertures 24 and 25 slide into interlocking enf gageinent .with slots I5 and 20 as better shown in' Figures 1 and 3. A Y

Accordingly by this simple operation which may be easily performed. even without the assistance of tools, the handleY I3v is 'securelyatf ftached to plate I0 with no possibility of acci` vided inthe door for studs |5 and |6 as well as flange portions22a `and 23a and their associatedY parts, the edges of border flange I and flanges 22 and 23 may rest flush against the door thus acting to reenforce plate I0 against any lateral bucklingfor bending. Y Y

As more clearly shown in vFigures Zand 4, the

Vupper portion of fastening part 2|"has formed therein an aperture 26 between flange portions 22a and 23n and in registry with an aperture 2'| in face plate Ipwhen the partsV` are lin the- `'above-described assembled position.` Extendingthrough apertures 26 and 21 is a thumblever generally indicated at 28. A pair of aligned holes' 29 and 30 areprovided in flange portions 22a and 23a V(Figure 4) and extending therethrough and through thumblever 28 is a pin 3| provided with a suitable Cotter pin 32 for holding it in its'assembled position; Accordingly thumb lever 28 pivots about pin 3| thus to actuate various parts of the lock construction by way 'of portion 28@ which is in association with these parts. .Fur-4 thermore, lever 28 when in position locks fastening 'part 2| in its downward or fastening position It Willnow become clear that I have provideda lockV construction v chiefly characterized `by the simplicity of its construction and the 'unity of its various parts. For example, `'handle-I3 maybe secured to plate l0 by the simple operation of slipping fastening part 2| into the position shownV in Figures 1 and 2. Y After thumb lever 28 has been Vsecured in position, the assembly is com-V plete and not only are the parts locked into their normal positions but, also, theyl act in a reenf forcingcapacity to strengthen the plate l0. Also the number of individual parts required for this construction is very small thus making for easy and convenient shipment aswell as 'ease of assernbly.v I

Preferably plate I0 as well as part 2| is formed Vfrom a suitable sheet metal material. Thus these4 parts may be stamped, or otherwise formed in a convenient andveconomical manner, and, due to the reenforcing action of part 2| (more particumains unusuallvstrongalthough formed from a comparatively weak material'.

' It willthus be seen that I haveprovided a thoroughly practical ,and efficient construction in Awhich the several VVobjects hereinabovev men-V tioned aswell as many others are successfully and practically accomplished; y

As many possible embodiments may be Vmade of the mechanical'features'of the -fabove invenl-VV tion andV asu the lart herein, Adescribedmight be varied in various parts, all without` departing fromthe scope of the inventiomit istobeunderstood that all matter-hereinabove'setforth-orv shown inthe accompanying drawing is to beV interpreted as illustrative and not in a'limiting sense.Y y
