.This invention relates to a knock-down structure designed primarily for use, when assembled, as a voting booth, but it is to be understood that a structure in accordance with this invention isy for 5:: employment'in any connection for which it may be found applicable.
As is well known, it is the practice in many counties, between election days, to place Voting booths of the canvas type in the care of some- 110'2 one living in a township; usually the constable. However, despite the care that is taken of them, the booths are often destroyed or seriously damaged from one election to the other. Rain, rats, rot and insects take their toll, and the booths beli come soiled or impaired to an extent to prevent their use at a coming election.
It is the aim of this invention to overcome the objections referred to with respect to a booth of the canvas type and to such end the invention 20. consists in providing in a manner as hereinafter set forth a voting booth formed of a set of metallic interengageable elements so formed as tovenable them of being expeditiously assembled to provide a durable voting booth and of being quick- 25. ly disassembled and arranged in a compact manner for storage.
The invention further aims to provide, in a manner as hereinafter set forth, a strong, durable, voting booth of the knock-down type having the 30, elements thereof of metallic material of novel form and of simple construction, and with such elementsl so constructed to readily engage one with another, to assemble the booth in a rigid manner and to be quickly disengaged for the pur- 35, pose of dismantling the booth when desired.
The invention further aims to provide, in a manner as hereinafter set forth, a strong, durable, compact voting booth which is comparatively inexpensive to manufacture; pleasing in appear- 40 ance; having the elements thereof capable of being washed when desired; and with the elements so formed to enable their quick assembling in detachable relation to provide the booth and their quick disassembling to knock down the booth.
To the above ends essentially and to others which may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts as will be more specifically 5mv referred to and illustrated in the accompanying drawings wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted to which fall Within the scope of the invention as 55 claimed.

The posts I, 2 are constructed from metallic material, are of the same length and preferably will consist of a pair of sections which are to be coupled together in endwise abutting relation. The sections of each of the rear corner posts are indicated at II, I2. One end terminal portion of the section I! has secured thereto and extended therefrom a coupling sleeve I3. When the sections Il and I2 are coupled together, one end of the section I2 extends into the sleeve I3 and abuts an end of the section IE. The inner` diameter of the sleeve I3 is such with respect to the outer diameter of section I2 to providefor the latter to frictionally engage with the inner face of the said sleeve I3 whereby the sectionsII and I2 are coupled together in endwise relation. The section II of each rear corner post is formed near its upper end with spaced slots I4, I5, I6 lengthwise thereof. The slot I5 is spaced ninety degrees from the slots I4, I6. The slots I4, I6 are spaced one hundred eighty degrees apart. The slots I4, I6 are diametrically opposed. The slot I5 is arranged in the front of the section 4I I. Slots I4, I6 are arranged in opposite sides of the section II. When the corner posts I, 2 are coupled together and set up in upstanding position, the slot I4 of the section II of the corner post I aligns with the slot I4 of the section II of the corner post 2. The slots i6 of the sections I! of the rear corner post are used when connecting annex booths to the master booth. The section II of each corner post is provided in proximity to the sleeve I3 with a set of spaced slots I1, I8 and I9, which vertically align in; spaced relation with the slots I4, I5, I6 respectively of such section. Although each of the iront corner posts preferably will be formed of two sections, it is to be understood that each may be formed of a single length of material. The slots I4, I5, I6 are termed an outer set. The slots I6, I1, I8 are termed an inner set.
The front corner posts 3, 4 are of like form and each is constructed in the same manner as, and is of the same length as the rear corner posts. The sections of each front corner post are indi- I gauge.

The slots 22, 25 are arranged in the back of the sections 2D and align with the slots I5 of the sections II. The slots 23, 24 of post 3 are arranged respectively in the outer side and in the front of the section 29 of post 3. The slots 23, 24 of post 4 are arranged respectively on the inner and outer sides of the section 20 of post 4. The slots 26, 21 of post 3 are arranged respectively in the outer side and front of the section 20 of the post 3. The slots 21, 28 of post 4 are arranged respectively on the inner side and front of the section 28 of post 4.
The back wall forming element, as well as each side wall forming element consists of a rectangular panel 28 formed of sheet metal of the desired The marginal portions of the panel are bent against the inner face of the latter throughout, to provide the folds 29, 30, 3I and 32. The
Vfolds are mitered as at 33. The folds constitute reinforcements for the panels. The fold 3I is slitted, at 34, 35 and at 36, 31. The material freed by the slits 34, 35 is bent outwardly to provide an attaching lug 38.4 'Ihe material freed by the slits 36, 31 is bent outwardly to provide an attaching lug 39. The fold 32 is slitted as at 4D, 4I and the material freed by such slits is bent outwardly to provide an attaching lug 42. The fold 32 is slitted as at 43, 44 and the material freed by such slits is bent outwardly to form an attaching lug 45. The attaching lugs extend from the side edges of the panel. The slits in the folds 3I, 32 are so formed whereby each attaching lug (Figure 9) will consist of a rectangular part 46 and a tapered part 41 extending from the inner side of the part 46. The part 41 is arranged in spaced relation to the side edge of the panel 28 thereby providing a gullet 48. The attaching lugs are arranged between the transverse median and ends of the panel 28. Secured to the inner and outer faces of the panel 28, in proximity to the lugs 39, are suspension members 49, 58 of strap-like form. 'Ihe members 49, 50 are arranged in alignment and each consists of a pair of end portions 5I, 52 and an intermediate portion 53 which is offset with respect to the portions 5I, 52. The members 49, 58 are oppositely disposed and the end portions 5I, 52 are suitably anchored to the panel 28 in proximity to its side edges.
The shelf forming element 8 consists of a body part 54 formed of sheet metal of the desired gauge, and having oppositely disposed rounded inner corners 55, 56. The body part 54 is formed with a cutout 51 opening at the front thereof when the shelf is set up. The shelf constitutes what may be termed a desk. The cutout 51 has a substantially semi-circular edge portion 58 and a pair of oppositely outwardly inclined edge portions 59, 60. Formed integral with the body portion 54 and coextensive with the edge of cutout 51, as well as disposed at right angles to the outer face of body part 54 is a flange 6I which is vertically disposed when the shelf is mounted in position. Formed integral with the rear edge 62 of the body part 54 and arranged between the corners 55, 56 of such body part is a flange 63 disposed at right angles with respect to the latter and depends from body part 54 when shelf 8 is mounted in position. Each side edge 64 of body part 54 has formed integral therewith a fiange 65 which is disposed at right angles with respect to body part 64 and depends from the latter when the shelf 8 is mounted in position. The flanges 6l end parts are termed extensions.
extend from the corners 55, 56 to the front end of body part 54.
Each hinge connection 9 (Figures 7 and 8) consists of. a semi-cylindrical body portion 66 formed intermediate its outer periphery with a crescent-shaped extension 61 provided centrally thereof `with an opening 68. The extension 61 isdisposed at right angles to the body part 66. The inner face of body part 66 on its lengthwise median has formed integral therewith an angleshaped attaching lug 69 disposed in lengthwise relation with respect to said inner face and extending inwardly from the latter. The element 9 is constructed from sheet metal of the desired gauge.
The door forming element IIJ consists of a rectangular panel 15 formed of sheet metal of the desired gauge. The marginal portions of the panel 15 are bent inwardly against one face thereof to form folds 16 which are mitered, as at 11. The panel 15 is cut out at spaced points as at 18, 19. The cutouts are aligned in spaced relation and open at an edge of panel 15. Ancho-red to one face of the panel 15 is a pair of spaced aligned hinge members 80, 8| consisting of a leg 82 and a leg 83 disposed at right angles to the outer end of leg 82. The legs 82 are anchored to the panel 15 and each aligns with what would be the upper wall of a cutout when the element ID is mounted in position. The legs 83 align with the open ends of the cutouts, but said legs 83 are of such length that they terminate above those walls of the cutouts which are disposed parallel to the walls of the cutouts' with which the legs 82 align. The manner of Asetting up the legs 83 with respect to the cutouts form passages 84 (Figure 8) for a purpose to be referred to.
The bracing bar or element Illa is formed from a length of sheet metal having an intermediate part and a pair of end parts o-f materially less width than the said other part. The side edges of the end parts are spaced equi-distant from the side edges of the intermediate part. The The web other than the extensions is folded from each side upon itself to provide element Il!a to include a flat body part 10 of a cross sectional contour as shown by Figure 16. The end terminal portions of body part 10 are bent to form a pair of depending legs 1 I, only one shown. The lower ends of the leg 1I merge into upstanding inwardly inclined resilient latching members 12 provided by the extensions at the ends of the intermediate part of the web. After the legs 1I are formed the said extensions are bent upwardly and inclined to provide the members 12.
The combined latching and coupling caps Illb are of like form and each consists of an annular cap-like body 85 closed lat its upper end, as at 86, and opening at its lower end. The body 85 is provided with a circumierentially extending bayonet-shaped slot 8 1. Formed integral with the outer face of body 85 is a set of three radially disposed yokes 88 disposed in equi-spaced relation at right angles to each other to form in connection with body 85 closed loops 89. The yokes 88 extend from three sides only of the body 85. The slot 81 is arranged below the yokes. The latter at their upper ends are flush with the top edge of a corner post. The'slots 81 coact with lateral pins 90 on the corner posts for detachably connecting the caps and posts together and. with the caps positioned on the upper ends -of the posts. The caps bearingfon the top edges of the side and back wall forming elements and latchvthem in position. `Thelnwardly extending aligned yokes of the caps on the front corner posts receive the legs 1I of the element Ia and with thebody part 10 of the latter seating on the top edges of such yokes. When element Il)a is mounted as aforesaid,A the members 1I bind against the bodies of the caps on the front corner posts for latching .element I0@ in bracing position with respect to the front of the booth.
It will be assumed that the rear corner posts I, 2 have been assembled. The-back wall form.- ing elementY is then detachably connected tothe sections II of the corner posts I, 2 by the lugs of said back wall forming element engaging in the slots I4, I1 of the sections II. A side wall forming element is then attached to the section II of the corner post I by certain of its `lugs engaging Vin the slots I5, I8 of the section II of the corner post I and the other lugs of the side wall forming element'engaging in thel slots 22, 25 in the section 20 of the frontl corner post 3. The other side wall forming element 6 is connected to the section II of the rear corner post 2 by certain of the attaching lugs of element I5 engaging in the slots I5, I8 `of section II. The
other attaching lugs of the element -are en` elements 5, 6 and the suspension members carried by such elements. The shelf when mounted in position is supported upon the suspension members 50 carried by the elements 5, 5 and 1. The caps Illb are then connected to the upper ends of the front and rear corner posts.
The hinge connection elements 9 may be atn` tached tov corner post 3 of corner post 4 and are shown by way of example as attached to corner post 4. The lugs 69 of the elements 9 are inserted into the slots 23, 21 of section 29 ofthe post 4. The extensions 61 project laterally from section of post 4. The door forming element I0 through the medium of the cutouts 18, 19 is then positioned to overlap and the legs 83 of members 8|), 8| pass downwardly through the openings 68 in the extensions 61 whereby the door will be hingedly supported from the corner post 4 and when swung open will appear as shown in Figure l. After the element I9 has been hingedly connected to the post 4,*the coupling bar IIla is then mounted into position and has the legs 1I thereof extend in and latched to the inwardly extended aligned yokes 88 of the caps IIlb on the front corner posts. After the elements and the coupling bar have been assembled in a manner as referred to, the booth will appear as shown in Figure 1.
When the elements 6, 1 and 8 are mounted in position, the corner posts engage in the gullets 48 provided by the tapered parts 41 of the attaching lugs 42, 45 and the manner in which said lugs are set up functions to retain the elements 5, 6 and 1 in position, relative to the corner posts. When the elements 5, 6 and 1 are set up the lugs thereon overlap a part of the inner faces of the corner post and also seat on the bottom Walls of those Slots through which they extend.
'Y The-connections between the elementsl 5, 6
and 1 and the corner ports are of detachable 75 form; andthis statementapplies'to the connections between the shelf and suspension members, the connections between the elements 9 and a corner post; the connection between the element i0 and elements 9, and the connections between the coupling or bracing bar and the front corner posts whereby the booth may be quickly knocked down or disassembled when desired.
