Application filed May 29,

This invention relates to supports, and with regard to certain more specific features, to supports for door bucks, window frames and like building units. 1 V I Among the several objects of the invention may be noted the provision of universally adjustable, portable means for supporting a door buck or the like in position, prior to building around it and permanently supportingit by extraneous building construc- 'tion; the provision of a device of the class described which is readily adaptable to supporting the buck in various locations and the provision of a device of the. class described which is light, easy to carry about and simple to apply. Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly comprises the elements and combinations of elements, fea-; tures of construction, and arrangements of partswhich will be enemplifiedin the structure hereinafter described, and the scope of the application of which will be indicated in the following claims. a

In the accompanying drawings, in which I areillustrated several of various possible emscrew. 4

It will be appreciated that bucksof-this type and similar objects in building constructions are setwith their lower ends on the floor or the like {and therethen arises a problem as to how .to support and accurately align the upper end, prior to applying the ordinary sup:

ports whichare provided for the bucks as the construction proceeds; The difliculties which have been met are that there are bucks of various sizes which are adapted to bepilt.

into various locations.- Thus it requires different lengths of supports and/or struts in order to reach to walls, ceilings or the-like, for supporting-purposes. Another dilfic'ulty has beenthat the buckshave been mutilated inapplying makeshift devices thereto, such as nailedbraces. My invention solves these and other difficulties and provides added im-:

provements not foundheretofore.

Referring again in particular to Fig. 1', it will be seen that'the support per se com-f prises a right and left-hand pair of braces 3, spaced from one another and adapted to be applied to opposite sides of a buck or the,

like. Each brace 3 comprises a corner plate 5 to which is riveted or otherwise rigidly fas-' tened-a strut 7 Adjacent each strut 7 is pive oted to the. corner plate 5, a double slotted guide 9, along which is movable a slide 11.

Therelationship between each slide 11 and its guide 9'is shown more particularly in Fig.

3, this figure also showing the application-of a locking screw and nut combination 13 through one guide slot for clamping and unclamping the slide 11 to and from the guide 9. It will thus be see'n th'ateach slide 11 may bepos itioned and locked in any given location or cle vation on its guide 9.

Hinged to each slide 11is aside arm brace 15 swingable in a plane at substantially a right angle to the swingor plate 5 of its respective guide 9. The purpose of the side arm braces 15 is to provide lateral support.

for the buck 1, said supportbeing such that a reactionmay be applied against ceiling or like surfaces of varying elevation, by suitable adjustment of the slides 11 in their guides 9 and by suitable swinging adjustments of the lateral braces 15 on their slides 11.

In order that given positions of the lateral braces 15 may be maintained in respect to the on one side only of the'laterally swingable' members, they do not prevent foldingaupnof the laterally swingable members 15 against the guides 9. The folding-;up.may:be done quickly without requiring that the wing nut 19Zbe adjusted.

Itwillbe seen that the adjusting feature of the-wing nuts 19 in connection with the sidearm braces 1'5 may be used for obtaining a-reaction to adjust=the position of the buck l ex-aetly. For instance, the support as a whole may be clamped :to the buck and the slidesl l runup-intoposition such'that a reaction isrobtainedbetween pieces-21 and the ceiling, as shownin'the" drawings. Thereafter, the wing nut 19 may bedrawn up so that the buck is iorced one way-or another, as desired, :to .obtain an "accurate alignment of the buck. At-the upper endsof the lateral braces'15 lthe pivoted channel shaped pieces 21-function'both'as supporting feet (see the leftside of :or as extensions '(see the right :sideof Fig. 1). When functioning as extensions, themembers '21 are limited in their angular rotation on the respective braces 15 by the fact that the ends of the braces 15 lie -in 1the channel space and the tendency to :turn, caused by a reaction against the ceiling,is :thus limited. It will be seen from Figs. Land '2 that the side braces '3 may be folded up by laying them against the guides 9 and running their sliders 11 down to sthe'bottomsiof the guides 9 and then folding .the guides 9 against the struts '7. The supporting members '21 may also 'be rotated into position substantially parallel with the length :of the then parallel members 7, 9, and 15. i

In order that the side braces 3 maybe held together as a unit and at the same time ibe'apw plicable to various bucks, window 'jambs, and the like they are connected by a plurality (three in the present instance) or draw screws One of these draw screws conaf neots the plates 5, one connects the ends of struts 7, and another connectsthe ends of the guides-9. Each screw passes through an opening at one end of a 'U -shaped member 25' connected to one of the braces 3. Within each 'U shaped member is a non-rotatable nut into which passes said screw. Each screw 23 at its other end passes through a collar 26 which permits rotation of the screw without longitudinal movement. Thus it is possible by means of cranks 27 connected to the screw, to draw the side braces 3 together or to permit them to be separated. Hence there is effected a clamping action on the bucks by the screw-connected braces 3.

In order that the buck may be positively gripped by the clamps or braces 3, the ends of th struts 7 and the guides 9' are. pr0vided with threadedmembers 29'the inner "ends of which are pointed as shown at numeral 28 in Fig. a and theiouter. ends of which have handles 81. By this means a definite grip may .bewfiected on the wood of the bucks, which grip may be adjusted to a degree which Will net substantially mar the surface of the bucks as would nails.

it will be understood that 'althoughthe abcvedescrip'tion showsonly one 'corn'enof abuck, that a device-such as herein disclosed may be applied to each corner.

Re the'feet 21,-itwillbe seen'that when used flat, (left ofFig. '1 they may be used against finished surfaces, such as lat-hed orplastered ones, whereas when used as shown at-the right of Fig. 1, 'it is preferable that harder survfaces suc'li :as-concrete or the like be available.

'In view of theabove, it will be seen that the several objects of the invention are achieved and other advantageous results atta'ined.

As many changes could be made in-carrying out the above constructions without-departing from "the scope of the invention, it is intended that all mattercontained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a 'limit'inggsense.
