SHINGLING-BRACKET'.

SPECIFICATION forming part of Letters Patent No. 703,894, dated July 1, 1902.

Application filed September 25, 1901. Serial No. 76,515. (No model.)

to support one end of a scaffold or board whereby the operator is enabled to superpose other shingles in his progress toward the comb or apex of the roof; and the object had in view is to provide a device of this kind which may be applied with facility to the exposed lower edges of secured shingles and may be held efiectivelyin place to support the weight of the scaffold and its occupant.

With these and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a shingling-bracket, as will be hereinafter fully describedand claimed.

In the accompanying drawings, forming a part of this specification, and in which like numerals of reference indicate corresponding parts, there is illustrated a form of embodiment of the invention capable of carrying the same'into practical operation, it being understood that the elements herein exhibited may be varied or changed as to'shape, proportion, and exact manner of assemblage without departing from the scope of the invention, and in these drawings Figure 1 is a view in side elevation, exhibiting the bracket applied to aroof. Fig. 2 is a detach ed detail perspective view of the bracket.

Referring to the drawings, 1 designates, generally, the bracket, comprising a stationary base member 2, a pivoted clamping member 3, an adjustable scaffold-rest 4, and a restadjustinglink 5.

The base member 2 comprises a plate of metal having a longitudinally-disposed upstanding reinforcing-rib Sand is provided at one end with a flat jaw or plate 7, provided on its upper face with a plurality of studs or prongs 8 and at its opposite end with two prongs or feet 9, which extend below the under surface of the plate and are designed to bite into the roof member upon which this end of the bracket rests. The base member is provided adjacent to the jaw 7 with an upstanding bifurcated hoss 10, between which is pivoted the clamping member 3, a bolt or screw 11 serving to hold the clamping member associated with the boss. The rear end of the clamping member carries a clampingscrew 12, which is adapted to engage with a bearing-surface 13 on the rib 6, thereby to move the forward end of'the clamping member to or from the jaw 7, and carried by said outer end of the clamping member and pivotally connected therewith is a jaw 14, provided on its under surface with studs or prongs 15, adapted to coact with those on the jaw 7 to efiect clamping and securing of the bracket to a shingle or board on the roof. In order to effect the most efficient securement of the bracket to the roof member, the prongs of the two jaws are by preference arranged in staggered or break-joint order, by which ar- 'rangement it will be seen that a larger area of the roof member will be engaged by the prongs than if the same were arranged in alined order, so that when the jaws are once clamped to the roof member the bracket will be held securely in place. Any suitable means may be employed for securing the jaw 14 to the clamping member 3, the means in this instance employed being to provide the jaw 14 with a bifurcated boss 16, through which passes a screw or bolt 17 to connect it pivotally with the clamping member 3.

The adjustable scaffold-rest 4 comprises a plate provided on its upper edge with a plurality of prongs or steps 18, which operate to hold the scaffolding against shifting rearward in the use of the device, whereby the carpenter will always be within easy reach of the work to be done. Near the forward end of the rest 4 and on the under side thereof are provided two ears 19, adapted to straddle the outer end of the clamping member 3, and

through these ears and the clamping member is passed a belt or screw 20 'to' effect pivotal connection between the parts. The rear end portion of the rest 4 carries a transverselydisposed pin 21, the ends of which are designed to engage recesses or seats 22, formed in the rear upper portion of the rest-adjusting link 5, the recesses by preference being curved inward and downward, thereby to prevent accidental separation of the pin therefrom in the event of the locking means, presently to be described, not being in position to lock the rest and link against separation. The link comprises a strip of metal bent upon itself to present a yoke, and the lower extremities thereof are held assembled with the rib by a bolt 23, the rear portion of the clamping member being passed between the yoke members and being guided thereby and held from lateral play. The link is curved rearward from the rest 4 to correspond with the are described by the rear end of the rest when the same is being adjusted to cause it to occupya horizontal plane irrespective of the pitch of the roof being shingled. To hold the rest in adjusted relation with the link, a pivoted locking-latch 24 is associated with the rest, the latch being provided with a laterallyextending projection 25 to engage a notch 26, formed in the rest contiguous to the front wall of the link. When the projection is in engagement with the notch 26, as shown in Fig.1, disengagement of the pin members from the recessesof the link will be positively prevented, and to eifect adjustment of the rest it will oniy be necessary to close the latch to the position indicated by dotted lines in the said figure, rock the link toward the forward end of the bracket to throw the pin out of engagement with the recess thereof, and then move the rest up or down, as may be required, and then bring the locking-latch again into engagement with the notch.

When the bracket is to be placed in posilion upon a roof, the lower jaw 7 is inserted under a shingle that has been nailed or under a board, as shown in Fig. 1, and the clamping-screw 12 is turned down, thereby forcing the jaw 14 down upon the roof memher-and causing the respective teeth or prongs of the two jaws to bite into the roof member. The rest i is then adjusted in the manner already described to bring it to a horizontal position, after which the scaffold or board is placed on the rest. The weight of the scaffold and its occupant will cause the rear pronQs 9 to bite into the shingles, thereby presenting a holding means supplemental to the prongs or teeth of the jaws to hold the bracket from slipping or becoming detached from the roof member.

It will of course be understood that two of these brackets are to be employed, and as this will be' obvious illustration thereof is deemed unnecessary.

By having the jaw 14 pivotally associated with the clamping member the same is rendered automatically adjustable to the surface against which it contacts, so that positive clamping of both sides of the piece of wood or the like will positively be effected whether such wood be of the same thickness throughout its length or tapered, as in the case of a shingle.

It will be seen from the foregoing description that while the device of this invention is exceedingly simple of construction the arrangement and disposition of its parts are such as to present a device that will be thoroughly efficient in operation for the purposes designed.

Having thus fully described the invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A shingling-bracket comprising a base member provided at one end with a toothed ex tension for insertion beneath the free edges of a shingle and at its opposite end with prongs, aclamping member pivoted to the base member and carrying a movable toothed jaw, a scaffold-rest carried by one end of the clamping member, a rest-adjusting link car-- ried by the base member and provided with seats or recesses to be engaged by offsets carried by the scaffold-rest, and means for adjusting the clamping member with relation to the base member.

2. A shingling-bracket comprising a base member provided at one end with a toothed extension for insertion beneath the free edges of a shingle and at its opposite end with prongs, a clamping member pivoted to the base member and carrying a movable toothed jaw, a scaffold-rest carried by one end of the clamping member, a rest-adjusting link carried by the base member and provided with seats or recesses to be engaged by offsets carried by the scaffold-rest, means for adjusting the clamping member with relation to the base member, and locking means carried by the scaEold-rest.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
