SCAFFOLD-BRACKET.

Specification of Letters Patent.

Patented Nov. 26, 1918.

Application filed August 9, 1916. Serial No. 113.857.

To all whom it may concern Be it known that I, SAMUEL S. CoL'r, a citizen of the United States, residing at Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Scaffold-Brackets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

This invention relates, generally, to improvements in brackets; and,.the present invention has reference, more articularly, to a novel construction of sea old-bracket for use in connection with any form of scaffoldings, such as are employed by builders, painters, etc.

The present invention has for its principal object to provide a novel and simply constructed bracket of the general conformation hereinafter more particularly set forth, which is readily applicable to the uprights or other members of any suitable form of scaffold, is positively held in its supporting relation upon the members of a scaffold, and is readily detachable there from, the bracket being secured in its mounted position without the use of nails, screws, or the like.

Other objects of this invention not at this time more particularly enumerated will be clearly understood from the following detailed description of the present invention.

With the various objects of the present invention in view, the said invention consists, primarily, in the novel scaffold-bracket hereinafter set forth; and, the invention consists, furthermore, in the novel arrangements and combinations-of the various devices and parts, as well as in the details of the construction of the said parts, all of which will be more fully described in the following specification, and then finally embodied in the clauses of the claims which are appended to and which form an essential part of this specification.

The invention is clearly illustrated in the accompanyingdrawings, in which Figure 1 is a front view of the fragmentary portions of two of the uprights of a scaffold, with a bracket showing one embodiment of the principles of the present invention mounted upon each upright, with each bracket represented in end elevation; and Fig. 2 is an end view of the devices and parts represented in Fig. 1 and looking in the direction of the arrow w in said figure.

Fig. 3 is a top or plan view of the upper central portion of one of the said brackets, detached from the upright.

Fig. 4- is a fragmentary face view of a lower portion of the bracket, showing in connection therewith, and in front face view a fixture provided with a movable holding or retaining stud; Fig. 5 is a horizontal section of the same, said section being taken on line 5-5 in said Fig. 4; and Fig. 6 is a bottom view of the parts represented in said Fig. 4, looking in the direction of the arrow 3 in said latter figure.

Fig. 7 is a front face view of the frag mentary portions of two of the uprights of a scaflold and a bracket-device connected with said uprights, but of a modified construction which, however, is still made according to and embodies the principles of the present invention; and Fig. 8 is a topedge view of the said bracket-device, withthe said uprights upon which it is mounted represented in cross-section.

Fig. 9 is an end-face view, on an enlarged scale and looking in the direction of the arrow 2 in Fig. 7, of a clamping device employed with the form of bracket represented in said Figs. 7 and 8; and Fig. 10 is a vertical section taken on line 10-l0 in said Fig. 9.

Fig. 11 is a top-edge view of certain portions or members of the said bracket-device, illustrating a modification of the means for securing said portions or members in their assembled relation.

Similar characters of reference are employed in all of the said above described views to indicate corresponding parts.

Referring now to Figs. 1 to 6 inclusive of the drawings, the reference-character l, in-

ing means for securing said securing ele-' ment or embracing device in its adjustable as well as separably mounted relation upon the upright l, or other suitable part of the scaffold,

The said angularly shaped element or member consists, essentially, of a suitable arrangement of angle-irons, usually four of such angle-irons being employed, as here shown in said Fig. 3 of the drawings, and

each angle-iron comprising a pair of right- 'angled members, as 3 and 4. Secured between the members 3 of each pair of angleirons, by means of rivets 5, or any other suitable fastening means, are the end-portions 7 of horizontally disposed bar or rodlike supporting elements 6, and secured between the other members 4 of each pair of angle-irons, by means of rivets 8, or other suitable fastening means, are the end-portions 10 of vertically disposed bar or rodlike bracing or sustaining elements 9. Connecting the outer end-portions 11 of the hori- .zontally disposed supporting elements 6 with the lower 'end-porti011s12 of the said vertically'disposed bracing elements 9, and

i secured at said respective end portions by means of

rivets

13 and 14, or any other suitable fastening means, are the angularly disposed braces or struts 15. As shown in the several figures of the drawings, each angleironis made with an outwardly extending tubular hub, as 16, whereby each pair of angle-irons, secured to the respective sup porting elements 6 and the bracing elements 9 in the manner previously stated, may be connected by means of a suitable tightening bolt 16, as will be clearly evident, each bolt being formed with a suitable head, as 17, and screw-threaded-shank, as 18. Mounted upon the screw-threaded shank of each bolt is a nut like tightening member, as 19, each member 19 being preferably provided with a lever 20 forming a handle.

.The referencecharacter 21 indicates a pair of links or plates formed at their ends with perforated end-portions or eyes, as 22, for the arrangement of the said links or plates upon, the respective bolts in the manner more particularly represented in said Fig. .3 of the drawings; Each link or plate '21 may also be provided with an arrangenasaeac ment of biting or holding teats or projections, as 23, which are forced into the upright or post of the scaffold when the embracing device is mounted upon the upright or post in the manner shown in the accompanying drawings, and when the device is secured in its clamped position by tighteningthe said nut-like'tightening members 19, by means of the said levers 20, as will be clearly evident.

As an extra precaution, there may be connected with the lower end-portions of the vertical bracing elements 9, suitable fixtures provided with movable holdingorretaining studs adapted to be driven into the said uprights or posts 1, substantiallyshown.

Each fixture herein-above mentioned" consists, essentially, of a box-like body 24, which is provided with a suitably formed lug, as 25, and is secured upon the face of the bracing element 9 by means of rivets 26, or other suitable fastening means. Upon its lower portion, the said box-like body 24 is slotted, as M126, and has a part 27 which provides a stop-lug for the purposes to be presently more fully described The opposite end-portions of the said box-like body 24 are left open, as at'28' and 29, so as to W provide a suitable guide in which is movably or slidably disposed a stud or pin, as 30, having its end-portion 31 projecting from the open part 28 and its suitably pointed end-portion 32 projecting from the open part 29, whereby the said pointed end-portion 32 of the stud or pin 30 is adapted to be driven into holding or retaining engagement with the upright or post 1, when the end-portion V 31 of the said stud or pin is I struck a blow with a hammer, or the like, as

will be clearly evident and as will be fully understood from an inspection of Fig. 2 of the drawings.

To prevent removal of the said stud or pin 30 from its operative position within the said box-like body 24, the said pin or stud 30 is provided with a downwardly extending projection 33 extending into the slot 126 adapted to be brought into arrested engagement with the stop-lug 27, the portion 31 of the said stud or pin 30 being provided with a laterally extending projection, as 34, which is adapted to be brought against the one end of said box-like body 24, so as to limit the movements of the saidpin or stud in either direction, and to prevent its displacement and loss from said box-like member or body24, as will be clearly understood from an inspection more particularly of said Figs. 4,5 and'6 of the drawings.

In lieu of the style of bracket made-"as shown in Figs. 1 and 2 of the-drawings, fa

lon horizontal su ortin' arm or bar as g P g a.

35, may be employed, and at the free endportion 36 of which may be secured a clampirig'device of the general construction represented in Figs. 7 to 10 inclusive.

'This clamping device consists, essentially,

of a suitably formed block 37 provided with lugs 38 adapted to embrace the free endportion 36 of the horizontal supporting arm or bar 35 and secured thereto by means of rivets 39, or other suitable fastening means. The said block 37 isalso provided with other lugs 40 adapted to embrace the upper endportion 41 of a vertically disposed braceelement or bar 140, being secured thereto by means of rivets 42, or other suitable fastening means. The lower end-portion 43 of said brace-element or bar 140 has secured thereto by means of a rivet 44, or other suitable fastening means, a strut, as 45, the upper end-portion of which is secured by means of a rivet 47, or other suitable fastening means, to the said supporting arm or bar 35, substantially as shown.

The said block 37 is also provided with an upwardly extending member or element, as 48, providing a suitable shoe which rests upon the side of the vertically disposed brace-element or bar 140. The said block 37 is furthermore provided with oppositely projecting arms 49, arranged in pairs, substantially as shown, said arms carrylng pivot-pins 50 which may be in the form of suitable screws or bolts, as will be evident. Pivotally connected with the said pivotpins 50 are suitably formed vise or clamplng members 51 provided with clamping or biting end-portions, as 52. In practice, these end-portions 52 are disposed upon opposite sides of an upright, post, or other part of a scaffold, substantially as shown in Figs. 7 and 8 of the drawings, and are forced into positive but detachable engagement with the upright, post or other part of the scaffold, by means of a connecting bolt 53 arranged in suitable holes or perforations 54 with which the said clamping members 51 are provided. Upon the screw-threaded end-portion 55 of the said bolt 53 is a nutlike or other suitably formed tightening member, as 56, which may be provided with a suitable operating lever, as 57, or other suitable means, for tightening the said members 51 and their jaws 52 in securely clamped relation with the upright, post, or other part of the scaffold, as will be clearly understood from an inspection of said Figs. 7 and 8 of the drawings.

Instead of permanently connecting the bars or elements 35, and the angularly disposed braces or

struts

15 and 45, by means of the rivet 47, in the manner represented in said Figs. 7 and 8, the horizontally disposed supporting-bars 6 of two brackets may be placed in overlapped relation, as indicated in Fig. 11 of the drawings, said overlapping members of the two brackets being suitably secured'together in their separable relation by means of suitable tightening bolts 58 which are passed through perforations in said overlapping members and nuts, as 59, upon said bolts 58 for securing the said parts, when assembled, in their tightened relation, as will be clearly understood.

I am fully aware that many changes may be made in the general arrangements and. combinations of the various devices and parts, as well as in the details of the construction of the said parts, as set forth in the foregoing specification, and as defined in the clauses of the claims which are appended to the said specification. Hence, I do not limit my present invention to the exact arrangements and combinations of the several devices and parts, as described in the said specification, nor do I confine myself to the exact details of the construction of the said parts as illustrated in the accompanying drawings.

I claim 1. A scaffold-bracket comprising a clamping device provided with means for the attachment of said clamping device to a member of a scaffold, angle-irons connected with said clamping device, a horizontally disposed supporting element connected with and extending from said angle-irons, a vertically disposed bracinrr element also connected with and extending from said angleirons, a strut connected with said supporting element and with said bracing element, a box-like fixture mounted upon said bracing element, said fixture having oppositely located openportions and a slotted part, a stop-lug extending across said slotted part, a stud slidably disposed within said box-like fixture, said stud having its respective endportions projecting from the oppositely located open portions of said box-like fixture, a laterally extending stop-projection connected with one end-portion of said stud, and a downwardly extending stop-projection also connected with said stud and extending into and movably disposed in the slotted portion of said box-like fixture.

2. A scaffold-bracket comprising an embracing device adapted to be mounted upon a member of a scaffold, said device consisting of angle-irons, said angle-irons being arranged in pairs and each angle-iron being provided with perforations, bolts mounted in the perforations of each pair of angle irons, links connected with said bolts, tightening means connected with each bolt, and a supporting means connected with said angle-irons.
