HUBERT F. KRANTZ, OF BROOKLYN, NEW YORK, ASSIGNOR TO KRANTZ MANUFAC- TURING COMPANY, INC.,` OF BROOKLYN, NEW YORK, A CORPORATION OF NEW YORK.

Application filed July 19, 1917.

To all whom t may concern:

Be it known that I, HUBERT F. KRANTZ, residing at Brooklyn, in vthe county of Kings and State of New York, have invented certain new and useful Improvements in Safety Panel-Boxes, of which the following is a specification.

This invention relates to a safety panel box which is an improvement over that shown and described in Patent No. 1,292,808, Jan. 28, 1919.

An object of the present improvement is to provide a compact and eiicient structure by means of which several switch units may be combined for service in connection with suitable bus bars, and in which the box is maintained of a symmetrical and attractive appearance.

A further object is to provide a spacious and well ventilated compartment for containing the bus bars and other elements.

A further object is to provide a structure in which the several switch elements and their contacts are arranged in a position between the bus bar compartment and the fuse compartments and to so arrange the parts of the structure that the several switch mechanisms and their contacts may be readily inspected either through the fuse coinpartinent or from the bus bar compartment.

A further object is to so arrange the parts that the main line wires may lead into the box, for connection with the bus bars, from a plurality of sides, and through well appointed spaces, and also that the branch line wires shall have spacious channels'and may lead into the box from various sides. l

A further object is to provide efficient means for supporting the several switch elements and their associated parts.

A further object is to provide a box made up of an inner housing and an outer housing, the outer housing being sufficiently larger than the inner housing so as to provide spacious channels for the main and branch line wires and having a common cover for both housings, to'provide the innci' housing with an auxiliaryl cover which` is spaced from the main cover to form a compartment of a size to receive the switch control-elements, all other elements of the device being hid by said auxiliary cover, the

auxiliary cover having an inspection doory Specification of Letters Patent.

SAFETY PANEL-BOX.

Patented J une 8, 1920.

serial No. 181,456.

above,fwill be in part obvious and in part pointed 'out in the course of the following description of the elements, combinations, arrangementsof parts and applications of principles, constituting the invention; and the scope of protection contemplated will be indicated in thev appended claims.

In the accompanying drawings which are to be taken as a part of this speciication, and in which I have shown merely a preferred form of embodiment of the invenion: Figure l is a longitudinal vertical sectional view through a panel box constructed in'accordance with this invention, the-view being taken substantially upon the plane of line I-I of'F ig. 3, and the switch mechanism being shown in the on position.

Fig. 2 is a top plan view of the complete panel box.

Fig. 3 is a top plan view of the panel box with the main cover removed, and a portion of the inner or auxiliary cover being broken away.

Fig. 4 is a transverse vertical sectional view taken substantially 'upon the plane of line IV of Fig. 3, and

Fig. 5 is a diagrammatic view showing the parts of Fig. l with the switch mechanism in the off position, with the inspection door open, and with the vmain cover removed.

Reicerring to the drawings for describing in detail the structure which is illustrated therein, the reference charcater L indicates the main or outer housing. This may be made up of any suitable material, either sheet metal or otherwise, according to preference. In the drawings it is shown as being made from sheet metal.

The reerence characterG indicates the inner housing. This also may be made of any suitable material, but preferably is made of an insulating material such as slate or the like. It is formed with a bottom wall 1,

wires likewise may enter the main housing..

at any desired point and ylead thence through suitable openings 14, formed in the front wall of the inner housing, into connection with the branch line terminals 15 which are within the inner housing, all as clearly seen in Fig. 3.

The main cover consists of a rigid, substantially integral, rectangular frame 16 and a central'door 17. rlhe frime 16 is detachably connected to the side and front and back walls 18 of the main housing by means of screws or the like 19. The door 17 is hinged as at 20 to one of the side members of the frame 16. A spring latch 21 engages between the door and the opposite side member 16 to normally retain the door closed. The door is thus carried by and movable with the frame 16 at all times.

The front wall 4 and the side wal-ls 2 and 3 of the inner housing are of such depth as to extend substantially to the inner surface of the adjacent members of the frame 16 and the side and end members of said frame are of a width to close the channels 6, 7, 8 and 9 regardless of whether the door 17 be opened or closed. The rear wall 5 of the inner housing, however, is of considerably less depth than the remaining walls 4so as to leave a wide open space 22 between its upper edge and the adjacent inner surface of the frame 16. l

The auxiliary cover is formed entirely within the inner housing and is made up of a rear section 23, which extends continuously between the side walls 2 and 3 ofjsaid inner housing, being fixed to said side walls by brackets 24 and 25. A series of switch unit sections 26, and a like series of inspection doors 27 complete this' cover and define a compartment, 28, within which the switch control elements are located. f

The rear section 23 is arranged obliquely, its upper rear edgeas 29 being close beneath the under surface of the main cover substantially ina plane directly above the wall 5 so as, in effect, to constitute a spaced ex tension of said wall 5.- The lower forward' in front of the front face of the wall 5, thus allowing for the wide open space 22 above referred to.

The intermediate portions of the lowerl edge 30 are fixed to supporting partitions 31. These partitions are arranged in the space beneath the auxiliary cover and may take any desired form. Preferably, however, they are shaped from sheet metal to provide flanges 32 and 33 at their upper and lower edges by means of which they may be connected to the edge 30 and to the bottom wall 1 respectively.

The switch unit sections 26 are detachably fixed to the upper surfaces of the flanges 32 in front of the edge 30, the outer sections being supported by the brackets 25, and each section 26 carries an independently operable switch mechanism 34, the operating handle, as 35, of which projects through a suitable opening, as 36, into the compartment 28.

Any suitable type of switch mechanisms may be employed but preferably a switch mechanism is employed which is similar to that shown and described in my pending application Serial No. 85,852, filed March 22, 1916, one of these is carried by and movable with each of the cover sections 26, and each switch mechanism includes a pivoted blade carrier 37 upon which a suitable number of double ended blades 38, for instance three as shown, is mounted for simultaneous movement by the handle 35. The rear ends of the blades 38 move into and out of engagement with the under surfaces of suitable main line contacts 39 which project forwardly from the upper surface of the rear wall 5, and the forward ends of said switch blades move into and out of engagement with the .upper surfaces of branch line contacts 40 which are fixed to the bottom wall 1. The branch line contacts 40 are fashioned to provide fuse clips, as v41, which coperate with .fuse clips 42 to provide mounting for the forward edges rest upon an angle bracket 45- which is fixed to the inner front wall 4.

Any suitable character of safety appliance may be used in connection with the surface of the doors 27 for retaining themy against being opened while current is flowing, and for other purposes, but preferably the safety appl1ance employed, is similar to that shown and described in my pending application first above referred to. This includes a latch 46, movable to interengage with the angle 45 and to simultaneously control the position of the switch mechanism, also a guard member 53 movable with the door to positively prevent operation of the switch mechanism while the door is open.

A series of insulatin partitions 47 is pro-.

vided, one for each o the supporting partitions 31 and these serve, with the partitions 31, to divide the space beneath the auxiliary cover into a plurality of compartments to which access may be independently afforded by the respective inspection doors 27.

One of the inspection doors may be opened and the necessary repairs or renewal made without in any way disturbing the free passage of current in the adjacent compartments. The opening of the one inspection door will not in any way influence the remaining inspection doors and none of the remaining inspection doors may be opened eX-,

cept when its adjacent switch mechanism be thrown into the off position. The mechanism of each compartment is independent in all respects of the mechanism of the adjacent compartment and yet all of the compartments are formed within a single housing, have common bus bars, a common inspectin opening (the opening v22) .and the partitions defining the compartments are rigidly held by a common supporting mem.

. provide ample barriersfor protecting the live main line contacts during such inspection, and in which a more thorough and complete examination may be made by the simple removal of a part which is normally fixed, the main cover.)

Furt er, the structure thus evolved provides a much enlarged and well ventilated space Jfor the bus bars, together with a well ventilated locality for the switch contact elements. In this connection it is noted that the heat generated by the operation of the switch blades finds an easy path of discharge through the opening 22 for dissipation into the channels 9, 6, 7 and 8. All of the switch blades and contacts may thus be maintained normally cool and no one switch blade is likely to become heated to any excessive eX- tent.

The supporting partitions 31 are preferably cut away as atv 48 and L19v to prevent possible arcing from either of the contacts 39, or 40. l

Theinsulating partitions 47 are preferably conneoted with the supporting partitions 31 by means of brackets 50 which arel designed to hold said insulating partitions substantially in alinementwith the partitions 31 and in position beneath the edges of adjoining inspection doors 27 so that the upper edgesof the insulating partitions constitute common abutments for said doors,.as is clearly seen in Fig. 3.

The manner of connecting the bus bars is of considerable importance and consists in provi-ding rearward extensions of the contacts 39 bent to provide supporting means for the bus bars adapted to hold the bus bars properly spaced away from each other and in their most appropriate positions within the channel 9. For the bus bar 11 there is a plurality of contacts 39 one for each switch compartment, and these collectively support the bus bar 11. For the bus bar 12 there is a plurality of contacts 39 one for each switch compartment, and thesecollectively support the bus bar 12. For the bus bar 1 3 there is a plurality of contacts 39 one for each switch compartment, and these collectively support the bus bar 13. The contacts 39 for the bus bar 11 are formed from strips of material which are bentupwardly and thence forwardly at theirl rear ends so as to carry the bus bar V11 in a position spaced above the upperl edge of the wall 5. The contacts for the -bus bars 12and 13 are formed of strips of material allof which are of substantially identical shape and size,

each having an off-set portion to which the respective bus bars are connected the strips for the bus bar 12 being .in reversed position as compared with the strips for the bus bar 13 and thus supporting said bus bars` 12 and 13 in superposed relation, the bus bar 12 being substantially in va common plane with the bus 11 and the bus bar 13 being in a plane below the bus bar 12, all as clearly indicated in Figs. 1 and5. The bus bars are all contained between the side walls 2 and 3 withinthe channel 9, and the main line wires lead into said channel and are connected thereto as above described.

Note that the side walls 2 and 3 are continued rearwardlybeyond the wall 5 as at 51 thus, in eii'ect, placing the bus bars within an inner compartment formed by the inner housing. Where the main line wires lead in through the side walls 18 of the main housing a portion of one or both ofl the side walls 2 and 3 may .be cut away to form an opening as at52 to provide passage of the main line Wires" to the bus bars as clearly seen Vin Figs. 1 and 3.

Fig. 5 of the drawings illustrates the manner in vwhich full inspection is afforded for all of the `mechanism within the device. This shows the main cover to ybe removed and the inspection door 27 to be open. With j the parts in this condition it will beseen that the front side of the switch mechanism, together with the fuses and lconnected conswitch mechanism with the bus bars and its contacts may be fully inspected through the opening indicated at X.

It should be noted that when installingl for use the device of this invention, the

after the inspection is completed. This ma-A terially simplifies the work of the inspector and renders possible a more complete installation before the time of the inspection.

It is also important to note that the inclined position of the wall section 23 admirably provides for the wide open inspection space 22 while` at the same time enabling the maintenance of symmetry in the shape and proportion of the parts of the main cover sothat a desirable appearance is presented from without.

While it is herein shown and described that the mechanism 34 are of such character that one side of each is adapted to be inspected through the opening 22, while the opposite side of the same switch mechanism is adapted to be inspected through one of the door openings 27, nevertheless, it will be apparent that the full spirit of this invention will be equally present in instances where the opening 22 may serve for inspection of one switch unit, while the door opening 27 may serve for inspection of a switch unit which may, or may not, be capable of being seen through the opening 22, the underlying principle, in this respect,

being that the opening 22 and the door openings, taken together, provide for ample inspection, from different sides, of all of the switch units, or mechanisms, which may be arranged within the box. Hence, wherever in the claims hereto appended, the term switch mechanism, or its equivalent, is employed, said term is intended to include either a single switch unit, or mechanism, or a plurality of units or mechanisms.

As many changes could be made in this construction without departing from the scope of the invention as defined in -the following claims, it is intended that all matter contained in the above description or shown in the accompanying drawings, shall be interpreted as illustrative only and not in a limiting sense.
