ROOF BRACKET Filed April 25, 1933 2 Sheets-Sheet 1 ATTO R N EY Patented Jan. 9, 1934 UNITED STATES PATENT OFFICE 2 Claims.
This invention relates to roof brackets applicable to various types of roofs for supporting scaffolding or to provide foot rests for persons while working on the roof and has for the primary object, the provision of a device of the above stated character which may be employed in numbers on the roof with perfect safety and which may be easily and quickly applied and removed from the roof without injury to the latter.
With these and other objects in view this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.
For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is an elevational view partly in section showing brackets applied to a roof and supporting scaffolding and constructed in accordance with my invention.
Figure 2 is a side elevation partly in section illustrating the application of the bracket to a roof.
Figure 3 is a similar view showing another manner of applying the bracket to a roof.
Figure 4 is a plan view illustrating the bracket.
Figure 5 is a sectional view taken on the line 5-5 of Figure 2.
Figure 6 is a plan view illustrating a heel for the bracket.
Figure 7 is a plan view illustrating a holding dog.
Figure 8 is a perspective view illustrating a locking dog carried by the bracket.
Referring in detail to the drawings, the numeral 1 indicates brackets applied to a roof for the purpose of supporting a scaifolding 2 so that workmen may readily carry out work upon the roof. It is to be understood that any number of brackets may be employed and that they may be used as foot rests for workmen by arranging a number of brackets over the roof. As all of the brackets are identical in construction, reference to one is thought sufiicient.
A metallic strip 3 is bent to form a rest 4 and a substantially vertical portion 5 arranged angularly to the rest 4. Extending angularly from the rest 4 is a toe strip 6 forming an integral part of the rest and has its free end tapered and also provided with openings 7 to receive fasteners for securing the toe strip to a roof. A base strip 8 is formed integrally with the substantially vertical portion 5 and is arranged at an angle to the portion 5 and in parallelism with the toe strip 6 and is adapted to rest upon the roof. The portion 5 forms a vertical support between the rest and the base strip and has secured thereto a heel plate 9 provided with teeth 10 to bite into the roof adjacent to the base strip. A holding dog 11 is secured to the rest 4 by a hinge 12 and a portion thereof is bent angularly and notched to form spaced prongs 13 engageable with the roof, as shown in Figure 2. A locking dog 14 is secured to the vertical support 5 by a hinge 15. After the holding dog is placed in position to engage the roof, the locking dog is swung into engagement with the holding dog and prevents the latter from moving out of engagement with the roof. The locking dog is provided with prongs 16 which also may be made to bite into the roof.
As shown in Figure 3 the toe and base strips may be placed under the shingles with the dogs biting into a shingle or the bracket may be applied to a roof, as shown'in Figure 2, where the toe strip as well as the base may be secured in the roof by nails or like fasteners. Should the bracket be employed upon a slate roof it is preferable that the toe strip and base be secured to a comparatively wide board so as to prevent cracking or breaking of the shingles.
A guard strip 17 is carried by the supporting strip 5 and projects beyond one end of the rest to be engaged by a scaffolding positioned on the rest. The toe strip is provided with a slot 18 to receive a roof fastener.
While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be madewithout departing from the spirit and scope of my invention, as claimed.
Having described the invention, I claim:
1. A roof bracket comprising a rest, a toe strip carried by the rest, a supporting strip carried by the rest, a base strip carried by the supporting strip and arranged in parallelism with the toe strip, a heel plate carried by the supporting strip to bite into the roof, a holding dog hinged to the rest to bite into the roof and a locking dog hinged to the supporting strip to bite into the roof and engage the holding dog.
2. A roof bracket comprising a rest, a toe strip carried by the rest, a supporting strip carried by the rest, a base strip carried by the supporting strip and arranged in parallelism with the toe strip, a heel plate carried by the supporting strip to bite into the roof, a holding dog hinged to the rest to bite into the roof and a locking dog hinged to the supporting strip to bite into the roof and engage the holding dog, and a guard strip carried by the supporting strip and projecting beyond one end of the rest.
