; My invention relates to demountable office partitions and more particularly to a floor 1 to supplement the ceiling lock, described in my former application, in holding'a parti tion, of the character described, secure ly in place.
A further object is to provide a demojunt able partition which readily'may be erected in an oflice, or a room of any-kind, without the use ofnails or fastening screws and may be secured to ceiling and floor so as to be as rigid as a permanent partition. 1 7
A further object is to provide a floor lock device which may be employed for-fastening oflice railings, sectional counters, etc. as well, as partitions, to floors. 1 I
Other objects and advantages will appear hereinafter and while I show herewith and will describe a preferred form offconstruc tion'l desire it to-be understood that I do not coniine'my invention to such preferredform.
but that various changes and adaptationsmay 6 be made therein without"departingfrom the spirit of my invention as hereinafter claimed. Referring to the drawings which accom: pany this specification and} form a part there-1 Fig. 1,is a view in elevation of a typical partition in which my ceiling lock andfloor lock are used as fastening means.

- -While the partition shown in these draw ings will be seen to be of the same general construction as that sh own in my former .a plication, a .somewhat fuller description .of certain details thereof will be given here, in order to facilitate a clear understanding of the variousrparts and their relation to each other: The reference numerals here used to designate the various parts do not, therefore, coincide with those-used to designate similar parts in the former application;
-:-A slightmodification in theconstruction of the. partition, because of the added floor lock feature, is the provision of a foundation strip 10, with a longitudinal groove 11 in its upper face adapted to receive'the lower ends of. the partition sections .12. =Each of saidsection's iszmade in the form ofa unit resembling a door-,1 with a top rail 18, a middlerail 14', and
a bottom rail 15 fitted between two'stiles' 16 and held in spaced relation to ea'ch-other by. thenna panel 17 and a glass platelS being fixed in tlie'lower'and upperfparts, respec-f tively, of each section. The box-cornice 19,
is mounted on theupper ends of sec tions 12 is equipped with a coping strip. 20 havinga longitudinalgroove 21- in its, upper transom sections 22. Pilas'ters are formed by longer casing pieces 23 fixed between founda tion'strip10 and cornice;l9 so as to :cover the, joints between adjacent partition sections, andshorter casing pieces 25L fixed between coping strip 20 andcap members 25 (design nated '23 and fully described ,-in, my former application) so as to cover the oints between adjacent transom sections.
My floor lock comprises an expansion shield 26 of any suitable type, a relatively longrodbolt 27, with a removable head 28 on its upper end and a'screw threaded lower end 29 adapted to screw into the upper end or bolt-head 30 of the expansion shield, and a series of clownturned hooksor anchors 31 mounted on said rod-'27 in spacedrelation toeachother, said anchors beingprovided with bearings 32 in which the rod may turn freely. WVashers 33 are placedcon the rod above and below the anchor bearings and pins 34 are fixed in the rod so as to hold said washers in contact with the bearings and thus to retain the anchors in their proper positions. A clamping plate 35 inthe form of an elongated washer, isinserted under the head-30' of the" expansion shield bolt. 7 V 7 One-"of the'fioor locks thus-formed is placed between each adjacent pair of partition'sec- V tions, longitudinal grooves 36 being runin their stile edges to provide clearance for'rod' 27 and notches 37 being cut therein at suitable intervals toprovide clearance for anchors 31'. The" rod and anchors are attached to the edge of one of the sections by means of suitable staples 38 driven therein.
The corners of partition sections12 are cut away as at 39 to provide clearance for clamping plate 35 and bolt-headv-30, of the expansion shield, and the corners of transom sections 22 are cut away as at 40 to provide-clearancefor bolt-* head 28.
Catch plates 41 are fixed at spaced inter vals, corresponding to the spacing of anchors- 31, on the rear faces of pilaster casing pieces 23*, suitable recesses 42 being cut in said rear faces, under catch-plates 41, to permit the" anchor hooks3'1 to pass behind them.- Long'itudinal grooves 44'are also" cut in the rear face'of vcasing pieces 23,: adjacent the edges thereof, said grooves being adapted to receive tongues 45which are fixed in the faces of stiles 16' ofthepartition sections, the purpose of these'tonguean'd grooves being to prevent any side/wise shif-ting'of the pilaster. casing with reference to the j oints" between the par ti-tion sections. 7, I
In the process of erecting a partition ofthe type, here shown holes46, spaced to correspondto the width'of the sections 12 and of a siz'e to receive expansion shields 26, are
' bored through foundation strip 10"and coinaiding holes 47 are drilled t a prop ndepth infthe floor 43'. Foundation strip 10' is then ai -in PQ i iQ n t floor and expansi shields 26 are inserted through holes 46 into holes 47, with clamping plates st lying dn greets-11"; and theif-bolts 30 are screwed;
down untilfoundation' strip 10 issecuray elainpeato the-fl or. Partition sections 12" are then' set up and threaded ends 29' of rodboltsa? are serewedintothe bolt hear-Is 30' of expansion shields 26, far enough to just hold them upright. Heads 28 are now removed from rod-bolts 27 and box-cornice 19, which has been provided with holes 49 to receive rod-bolts 27, is mounted on the upper ends of sections 12, heads 28 then being replaced on rod-bolts 27 with washers 50 under them. Pilaster casing pieces 23 are now set in place on opposite sidesof the partition sections and Mabel-n27 arescrewed down into expansion shields 26" until anchor hooks 3-1 engage catch plates 41 so as to hold the casing pieces firmlyc'lain'ped against the partition sections.
with tongues 45 inserted in grooves 44.
Transom sections 22 are finally set in groove 21 and secured in place to ceiling strip 51 by means ofmy ceiling lock'52, pilaster casing pieces 24 and cap' members 25 being set in place and fastened as described in my former application.
It will be seen that a partition may be constructed in the manner described without nails or fastening screwsso that it will be as rigid and durable as apermanent partition,- whilebeing in a condition to be easily removed at anytime. After removal the only trace" l'eft'behin'd is a few. holes in the floor which readily may be filled up so as to be completely eflaceda Having'thus illustrated and described my invention, I claim:
1. In a demountable'partitionmade'in sections, a foundation stri having a longitudinal groove adapted to receive the lower ends of the partition sections;- clam-ping means in said foundation strip'adapted tosecure it to afloor; a cornice copingfresting on the upper ends'of the partitionsections and loclnng means extending downwardly from said cornice coping to said clamping.
