' This invention relates to scafi'oldbrackets of the eneral class adapted for use on the walls of wooden buildings and other structures to serve as a sup ortmg means for 5 planks or platforms on w lch workmen may stand.

One of the objects of the invention is, to

provide a foldable scafiold bracket having an improved attaching bolt or connector which will re uire boring or cutting of only a small hole t rough the sheathing in order to connect the bracket to the wall of the building, instead of necessitatlng the cutting of a relatively large hole such as 1s necessary with those brackets having a hook to enga e the studding. In ractice the hole whic has to be cut will 0 y be five-eighths of an inch in diameter and, being small, it can be readily patched when the coat of stuccoing is applied, whereas with those brackets em loymg a hook to engage the studding, it as been necessary to out a hole some two by three inches in size whlch 1s diflicult to patch.

In connection with this part of the present invention, it is only necessary to provide a block through which the improved bolt connection passes, such block serving as a bearing piece for the handled nut employed on the bolt.

The laws of some of the States require the provision of means on a scaffold bracket to prevent the workmen or artisans from accldentally stepping off, or falling off of the scafiold. Heretofore, this requirement has been met in a more or less unsatisfactory manner by the provision of a wooden framework fastened in position.

Another object of my invention is to provide an improved attachment which may be readily connected to a scaffold bracket and serve to hold a toe board and a hand rail so that, in those States where the law requires protection such as specified, attachments embodying this improvement may be connected to the scaffold brackets and utilized to hold the toe boards and hand rails.

A further object is the provision of atoe board and hand rail attachment of improved construction which will be particularly adapted for use in connection with a scaffold bracket of the type hereinafter described and in that respect I have combined my improved toe board and hand rail attachment with my improved scaffold bracket so that the two may be used together, or be folded into compact arran ement for handling or transportation wit out requiring detachment of the toe board and hand rail attachment from the scaffold bracket. On the other hand, however, the joint and locking device provided on the attachment permit the attachment to be removed if it is not desired or needed; furthermore, the joint and locking connect-ion permit interchangeability of use of the attachment, so that it may be applied to any scaffold bracket of the type hereinafter set forth.

A practical embodiment of the invention is shown in the accompanying drawings in which:

Figure 1, is a perspective view showing the complete scafiold bracket and the toe board and hand rail attachment in use on the wall of a wooden building, a part of which, as also the scafiold or flooring and the toe board and hand rail, are shown;

Fig. 2, is a perspective view of the scaffold bracket alone, showing how it may be used by itself;

Fig. 3, is a similar view of the hand rail and toev board attachment;

Fig. 4, is a perspective view of the comlete scaffold bracket, and hand rail and toe oard attachment shown in folded position Fig. 5, is a similar view of the scaffold bracket alone when in folded position;

Fig. 6, is a plan-view of the complete scaffold bracket and hand rail and toe board attachment shown in folded position;

Fig. 7, is a detail view showing the pivot and lock for the hand rail and toe board attachment;

Fig. 8, is a section on the line 8-8, Fig. 7 and Fig. 9 is a detail perspective view showing the manner in which the bracket is attached to the building.

The complete combination scaffold bracket having hand rail and toe board attachment appears in Fig. 1, the hand rail and 100 toe board attachment being shown as locked in upright position.

The parts comprising the complete combination bracket of Fig. 1 are shown, independently, in Figs. 2 and 3'to afford a clear 105 understanding that, while the complete bracket and attachment are connected, nevertheless they may be disconnected and used separately. That is to say, if the hand rail and toe board attachment of Fig. 3 is not uired, it may be removed from the seaffo d bracket shown in Fig. 2 and used on another scafiold bracket such asshown in Fig. 2 and the scaffold bracket of Fig. 2 may be used alone.

Referring first to Figs. 1, 2, and 9, the scaffold bracket comprises a bar or support 1 rovided with an upwardl projecting retamer 2 to prevent the plan or other platform supported by said, bar from accldentally slipping ofi it when the bracket of Fi 2 is used alone. The bar is rovided wit holes 3, 4, whose purpose ,wll appear presently.

The main supporting braces or legs are shown at 5 and 6, being pivoted by means of a bolt 7 t0 the outer part of the bar 1. These braces have bent feet 8 which may have openings to receive nails driven into the wall of the building on which the bracket is used, or these openings may be omitted. The braces 5, 6, are preferably of angle iron for the sake of strength and they are connected by a cross piece 9- which ispreferably riveted thereto and which may be of angle iron. The supporting braces being spread apart to a considerable extent and rigidly connected by the cross piece 9, they afford a wide bearing on the side of the building and prevent lateral movement of the bracket.

A tie or hanger 10 straddles the bar 1 and is pivoted to the braces 5, 6, as shown at 11. As shown, this tie or hanger 10 is made of a sin 1e piece of bent rod whose apex 12 is sufliciently broad to permit it to slide on the bar 1 when adjusting the bracket or when folding or extending it.

I wish it to be understood, however, that the tie or hanger 10 does not have to be made in a single piece nor is it necessa to pivot the hanger to the braces 5, 6 in t e specific manner shown at 11 where the ends of the tie or hanger are bent outwardly and are received in holes in the braces 5, 6.

It is also to be understood that the part of the tie or hanger which straddles the bar 1 may be of any suitable construction and not, necessarily, the bent part or apex illustrated, as it is well within the spirit of the construction in question to provide a special hanger at the upper part of the tie 10 where it is supported by the bar 1.

The tie or hanger 10 transmits directly to the supporting braces 5, 6 any weight imposed upon either side of the supporting part 1, thus preventing any twisting motion which would result in the walking of the feet 8 on the wall of the building.

As thus far described, and subject to the modifications which have been explained, and except for the provision of the holes 3,

4, the scaffold bracket a pearing in Figs. 2.

and 5 is substantially t e construction set forth in the patent to Bonenberger and Goodwin, No. 1,125,051, Januar 19, 1915.

bar 1 may be provided with an integral member 13.

The member 13 is provided with screw threads 16 for a considerable portion of its length and it carries a handled nut 17 engaged with said screw threaded part.

- The manner in which this connection is used is shown in Figs. 1 and 9. A hole, say five-eighths of an inch in diameter, if that be the size of the member 13, is bored through the studding 18 to which the sheathing 19 of the wall of the building is attached. It is then only necessary to pass the member 13 through this hole and to provide a separate block 20 with a corresponding hole 21 in order to anchor the bracket in the position shown in Fig. 1, when the handled nut has been applied and tightened up against the block 20. The block 20 serves as a bearing block for the handled nut 17 and distributes the strain over a suflicient area of the studding 18 to securely hold the bracket.

A very considerable advantage is obtained by the use of this improved connection because it is only necessary to bore 'a small hole to enable the bracket to be attached to the building, whereas with those brackets which employ a hook or special connection adapted,

to engage around the studding, it is necessary to cut a hole having an area of several square inches, usually, a hole of at least two by three inches in size.

As thus far described, the bracket which is shown alone in Figs. 2 and 5, is capable of use by itself without the combined hand rail and toe board attachment which is shown as connected thereto in Fig. 1 and which appears by itself in Fig. 3.

The provision of the holes 3, 4, however, adapts the scaffold bracket to be used in combination with the hand rail and toe board attachment as shown in Fig. 1 so that the complete bracket fulfills the requirements of the laws of those States which make it necessary to provide means to prevent the workmen or artisans from stepping ofli' of the scaifold or from falling therefrom.

The combination toe board and hand rail holding attachment or bracket comprises a bar 22, preferably of angle iron, which carries at its lower end a plate 23, riveted connections 24 preferably being provided to prevent accidental dis-connection. The plate 23 has a bolt hole 25 through which passes a removable hinge bolt 26. When the bar 22 is unlocked, it is not necessary to detach the hinge bolt 26 which then acts as a pivot, enabling the complete scaffold to be folded into the compact form shown in Fig. 4, inasmuch as the bolt 26 passes through hole 3.

For the purpose of locking the bar 23 in upright position, there is provided an improved J-shaped lockin bolt 27 which has its screw threaded sha passing through a hole 28 in the plate 23 and carrying a handled nut 29. Between the nut and the plate 23 are washers 30. The hook art of the bolt is adapted to enter the ho e 4 in the part 1 when the nut 29 is tightened, thus locking the bar 22 in the upright posit-ion shown in Figs. 1 and 7. As the J-shaped or hook-shaped bolt is carried by the late 23, as shown in Figs. 3 and 4, it is on y necessary to loosen the handled nut 29 sufficiently to enable the hook of the bolt to be withdrawn from the hole 4, in order to unlock the bar 22, as the pivot bolt 26 need not be taken ofl. When thus unlocked, the entire combination bracket may be folded into the condition shown in Fig. 4, the parts being in compact relation, so that the bracket occupies only a minimum amount of space and can be readily carried. about or stacked with other brackets for transportation.

I Riveted or otherwise suitably connected to the bar 22 are straps or bearings 31 and 32, the rivets or fastenings being shown at 33. One web of the bar 22 is provided with holes alined with the bearing parts of the straps 31, 32.

Clamping bolts 34 and 35 are mounted in the straps 31, 32 and have their shanks passing through the holes aforesaid. These clamping bolts are preferably of L-shape and provided with penetrating points 36 adapted to enter the toe board 37, and the hand rail 38, respectively.

The screw threaded shank of the bolt 34 ,carries a handled nut 39 and washer 40 interposed between it and the bar 22 and strap 31 for the purpose of affording a suitable bearing for the nut 39.

A similar handled nut 41 is provided on the screw threaded shank of the bolt 35 and there is a washer 42 similar to washer 40.

The scaflold or platform which is supported by the bars 1 of the different brackets connected to the. side of the house or building appears at 43 and, according to usual practice, may comprise planks or boards laid edge to edge. The clamp bolt 34 is turned downwardly, when in use, as shown in Fig. 1 and its point 36 penetrates the toe board 37. The hook of the clamp bolt 35 is turned upwardly to support the hand rail 38 and, on tightening the nut 41,

Referring to Fig. 1 which shows the combination hand rail and toe board attachment of Fig. 3 locked to the scaffold bracket of Fig. 2, it will be seen that the toe board 37 is supported on the bars 1 of the respective scaflold brackets and that the bars 22 afford an abutment to prevent the toe board from becoming displaced; also, that the toe board is held tightly against the bars 22 by the clamps 34. The handrail 38 is supported and tightly clamped against the up er ends of the bars 22 of the respective rackets. Therefore, as shown in Fig. 1, the complete combination bracket fulfills all requirements of the laws of those States which not only make necessary a suitable support for the platform but also require that provision be made to prevent the foot of the workman or artisan from slipping ofl of the platform and to prevent him from falling.

On the other hand, by reference to Fig. 2, in connection with Fig. 9, it will be observed that the bracket can be used without the toe board and hand rail attachment in those localities where the laws do not require protection for the workman or artisan against falling from the scafiold, or in those situations where it is unnecessary to provide such protection.

What I claim is:

1. A toe board and hand rail attachment for scaffold brackets, comprising a bar, means on the bar for its attachment to the scaffold bracket, and other means on the bar for securing a toe board thereto, and means for securing a hand rail thereto.

2. A toe board and hand rail attachment for scaffold brackets comprising a bar, means on the bar for securing a toe board thereto other means on the bar for securing a han rail thereto, means carried by the said bar whereby it may be pivoted to the scaffold bracket, and means carried by the bar for locking it to the scaffold bracket in upright relation thereto, whereby when the bar is pivoted to the scaffold bracket, it m-a be locked to said bracket, or unlocked rom the bracket without detachment from said bracket.

3. A toe board and hand rail attachment for use in connection with scaffold brackets, comprising a bar, means for connecting the bar to a scaffold bracket, and hook bolts carried by said bar, one of which is adapted to hold a toe board in position, and the other to retain a hand rail.

4. A combined scaffold bracket and to board and hand rail. support, comprising a scaifold bracket, and a combined toe board and hand rail bracket pivotally connected to the scaffold bracket and adapted to fold thereupon, and means for locking the combined toe board and hand rail bracket in upright .or extended relationship to the scaffold bracket.

5. A combined scaffold bracket and toe board and hand rail support, comprising a scaifold bracket having a supporting bar, divergent legs pivoted thereto, a hanger connecting the legs to the bar, and means for securing the bar to the building or structure on which the bracket is used, said bracket and adapted to fold down upon the' scaffold bracket, means being provided to lock the combined toe board and hand rail attachment in rigid upri ht relationship to the bar of the scaflfold racket, and upper and lower hook bolts carried by the bar of the combined toe board and hand rail bracket which serve to hold the hand rail and toe board;

6. A combined scaifold bracket and workmans protector, comprising a folda-ble scaffolding supporting bracket, a guard bracket pivotally and detachably connected thereto and adapted for folding in relation to the scaffold bracket, and locking means for securing the guard bracket in upright relafionship to the scaffold bracket.

In testimony whereof I aflix my signature.
