PANEL-BOARD CABINET.'

'Application inea May 6,1910, seriai No. 559,711.-

To all whom t may concern.'-

' Be it knownthat I, RAYMOND H. OLLEY,

Y a citizen of the United States, residing at Syracuse, in the county ofGnondaga and State of New York, have invented certain new and useful 'Improvements in Panel- Board Cabinets, of which the following is a specification. p

- This invention relates to improvements in.

panel board cabinets, designed for use in housing and protectingthe electric distributing parts, and the invention relates par-V ticularly tol thatclass of panel board work 40 Y f the'sa-id parts-for installationv in theca'binet y or boX. And a furtherobject is to' provide lsupporting devices vfor panel boards comprising but few parts, of noveland simple construction and arrangement, which may be i vsecuring thepanel board -and the which is inclosed in a box setting flush with or on'the surfaceof the wall of a building.

The objectof ,the invention is to provide a simple, strong and serviceable cabinet of the tclass, which is 'arranged with a compartment for containing theswitehes or cut outs, and which is surrounded by a wall for providing a'clo'sed gutter, lbetween the cutouts `and the-feed `and distributing wires. A further object is to provide a number of nveland coperating parts for adjustably Y p gutter walls to theinnerlside of the cabinet. yThe said securing means arranged at the several corners of the' panel board,and each consisting of a plurality of clampingmembers, capable of being readily' and quickly applied or removed.` v Each set of'clamping parts arranged for independently applying,v

adjusting or removing, and the several mem! @bers comprising each sety also capable of'v adjustmentin relation to each other. Y p n 'A particular object of the invention is to provide a seriesof' clampingsets or parts, by the'use'of `which the panel board base and the gutter lwalls require" no perforations or other .special treatment', in' order to .prepare "produced at yslight` expense and assembled and applied with a minimum' of skilled" labor. y

, To this end the invention consists of the novel construction and arrangement of the' parts as set forth in the detail descriptionV Specification of Letters Patent. ylgmtnjlged Feb, 22, 1916.

Renewed February 4, 1911. Serial No.' 606,642.

i which follows, as illustrated by the accom--A Figs. 3 andaL are' respec'ively a top plan and f a front elevation of the 'nner clamping member. Figs. 5.and 6 are sr ilar views of the main corner bracket and supwrt. Figs.

*7, and 8 are respectively an end and aside yiew of the-outer clamping member.k Fig. 9 41s asectional View, showing modified form of clamping arts, for use in securing panel -members in the same plane.

Similar characters of reference designate correspondingL parts throughout the` several views.

In the drawings, the cabinet proper consists of a box, open at-one face and comprising side walls 2, end walls 3, a bottom 4, and amat or cover 'whichis secured to matis disposed a panel board or base 9. The panel board 9 preferably corresponds informto'` the cabinet or box, and may have 2 the open face ofthe cabinet by screws 6. To gain access tothe interior of the 'cabinet' Van 'a larger orsmallerfarea than the opening inthe .mat 5; The panel basel), in the present device is'plaeeddirectlyagainst the flat bottom or back l of the boX. Againstv each side and end of the. panel'board yis' disposed` a relatively narrow strip of suitable ma.-

terial comprising the inner wallV l010and 11e-1l. Thesestrips are set on' edge, and at right angles` to the plane of the board 9. The'lower or inner. edges of the stripsklO andll preferably bear against the bottom 4.- of the boX, while their upper or outer edges preferably approach substantially to the undersidek ofthe mat 5. Under tliisvarrangement a closed space or gutter 12 is provided and extends all around the panel board in which Vthe feed and distributing wires and other connections may be conveniently installed.

To hold the parts comprising the panel board base and the strips which form the inner' walls of the gutter in place, I provide a series of cooperating clamping parts, and dispose the saine within the metallic boX, one set ot which is arranged at each corner of the panel board. The clamps for each corner consist of two opnositely formed

brackets

13 and 14, and a third angular member 15. The brackets 13 are substantially L-shaped and are disposed in diagonal position out-side of the corners of the panel board, and are secured to the bottom 4: ot the cabinet by screws 16, which pass through slots 17 formed in the foot or ange of each bracket, and thence through threaded holes 18 in the bottom d. The upright arm of each of the brackets 13 is formed at right angles to the flange or foot, and this portion is cast or formed into a right angle groove or corrugation which faces away from the lange and which receives the corner of the panel board 9. Vhen the tour brackets 13 are placed against the corners of the panel board and the screws 16 are tightened up, the board will be held from endlwise or sidewise movement, and by reason of the slots 17, the board may be adjusted so as to coincide with the opening in the mat 5. lThe inner bracket 111 has one end formed into a flange 11', which rests upon the face side ot the panel board, while the opposite end of this bracket is formed into a right angle groove or corrugation, which faces'the said flange and thus corresponds to, and is ca# pable of interlocking with, the groove in the bracket 13. The brackets or inner corner pieces 111 are positioned inside of the panel board inclosure, and are arranged to over lap the adjacent ends of the strips 10 and l1 and the edges of the upright portions or standards of the brackets 13 serve to prevent endwise movement of the lining strips too far into the clamping means and act as gages or guides by `which the position of the lining strips can be determinedV when being placed in position. Hence, said edges of the standards cooperate with the other parts of the clamping means to position the lining strips, although one or -both end edges of the lining strips may not engage the edges of the standard. In Fig. 1, the lining strips are shown as slightly spaced apart from the upright portions of the standards; and in Fig. 9, the lining strips are shown as engaging at their end edges the upright portions of the standard. By referring to Fig. 1, it will be seen that the strips 10 and 11 are each shorter than the ends and sides of the panel board, and are set relatively tothe board,

so as to leave an o enine or Ua at each cor ner. lThe brackets 1&1 when placed in position as shown in Fig. 1, close the gaps at the corners and serve to hold the panel board and the strips in true position. The brackets 13 and let of each corner set are then secured together by means of a screw 19, which passes through a slot 20 in bracket 14, and thence through a threaded hole 21 in the bracket 13. lVhen the screws 16 and 19 are tightened up the panel board 9 will be held from movement in any direction.

To hold the gutter frame parts 10 and 11 truly at right angles to the panel board and also tightly against the outer edges of said board, a clamping member 15 is disposed at each corner of the panel board inclosure, as shown in Fig. 1, in such manner that the lateral edges ot' the said members overlap the outer sides of the adjacent ends of parts 10 and 11. Each clamping member l5 is held in place by means of a screw 22, which passes through a slot 23, in the bracket 14, thence through a perforation 2d: in the bracketV 13, and thence into a threaded hole 25 in the member 15. The tightening up of the screws 22 will draw and hold the brackets 14 and members 15 tightly against the opposite sides of the gutter strips 10 and 11, and thus securely hold the latter in true position relatively to the panel board. The slots 2O and 23 in the brackets la are provided for affording adjustment of said bracket toward or away from the bottom of the boX,

to take care of the panel bases 9, which may be oit' varying thickness. The perforations 24 in the brackets 13 should be larger than the screws 22, for allowing the parts to be securely clamped to the wall strips without danger of cramping the said parts and rendering the clamps imperfect.

Fig. 9 illustrates a modified arrangement of the panel members, in which is shown two sections of a panel base 9', and also two of the side strips 10 of the same construction as shown in Fig. 1, which are so joined as to form a continuation one with the other in the same plane. This construction is generally followed where cabinets are of such length and width that additional sup ports are required for both the panel base and inner gutter walls other than those placed at the corners. Under this modified arrangement the corner supports are usually the same as shown in Fig. 1, but some additional supports are necessary at the sides or ends or both intermediate the corners, where the joints between the base sections and the wall strips occur. Inorder to properly secure and hold the panel. parts in place, as last described, I employ plain outer and in ner brackets 13 and 1111 and also an outer clamping part which consists of a flat plate 15 all of which parts are drawn and held in clamping position by a screw 22.

The panel board cabinets or boXes are usually made up by the manufacturer' and shipped to the'building contractors in advance ofthe installation of the electric parts. The matsor trim for the cabinets are made and fitted to the boxes and then re-v moved and laid aside kuntil the boxesV are embedded in the walls of the building. vAfter the. building is completed, the panel boards, gutter walls, and the securing devices for these parts, aswell as, theelectric i fittings are placed in position in the cabinet,

o and arrangement of the same, had to be as-A placed `in position tov close the open side of which comprise the panel board base and the gutter walls, as well as, the corner vclamping sets maybe finished and shipped by the fac-k tory to the place of installation in knockdown condition.

l in this manner much time is saved inthe assembling and packing of the parts, and besides there is little or no danger of anyf'of the partsbecoming broken or "injured in-rtransit. Heretofore under' many of the older methods of constructing and arranging the panel board cabinets, the

base andgutter walls 'and also the supportingdevices,owing to the'complicated nature sembled and set in the cabinets by skilled workmen before they goodsV were shipped to the place f. installation.` TV1Under the construction.` andr arrangement ofthe present device, none ofthe parts comprising the panel board or gutter walls require any perforations or ,other special workl to prepare vthem for installing the cabinets.A

The panel board bases may vary slightly in length, width gand,thickness and stillV beV readily lset inV placeywithout requiring any Vfurther. .cutting or change, as `all such discrepancies and ,inaccuracies are taken care of by the adjustablefarrangement of the clamping parts. All of` the supporting and clamping parts are made. and arranged in 1 thesimplest form, `and the whole complement of parts comprising the cabinet and electric fittings are capable of being assembled and installed ina readyand quick mannen by persons Vof ordinary skill.
