(NovModeL) P. KRAMER.


No. 380,395. Patented Apr. 3, 1888.




SPECIFICATION forming part of Letters Patent No. 380,395.,dated April 3, 1888.

Application filed November 25, 1887. Serial No. 256,168. (No model.)

To onZZ whom it may concern.-

Be it known that I, FREDERICK KRAMER, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Improvement in Roof-Climbing Devices, of which the following is a specification.

The object of my invention is to devise a foot-rest which can be attached to the foot and adjusted. to the pitch of any roof, so as to enable the wearer to walk over shingle roofs with but little inconvenience and with comparative safety. I accomplish this by means of the device described herein,and illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of my roofclimbing device as it appears when standing on a roof. Fig. 2 is a view of the under side of the sole-plate of my roof-climbing device. Fig. 8 is a plan of the top of the sole-frame. Fig. 4 is a longitudinal vertical section of the device on line at m, Fig. 3, the sole-plate being removed.

A is the roof-frame, at the corners of which are mounted the downwardly-projecting frictionpoints 13. Upon the front end of this frame is hinged the shoe or sole frame D,having thedownwardly-projectingsegmental arms E mounted at the rear end thereof.

At the rear end of the roof-frame are hinged the segmental arms 0. Each of the segmental arms E has a slot, G, through which a headed screw-bolt, H, is passed. The bolts H H pass through the ends of the segmental arms 0 and are secured by means of the thumb-nuts I I. At the end of each one of the arms 0, I provide a projection, J, adapted to fit into the transverse notches L in the segmental arms E.

When it is desired to set the device to fit the pitch of any roof, the thumb-nuts are loosened and the rear ends of the roof-frame A and shoe or sole frame D are set at such a distance apart that the shoe-frame D will be level when the device is placed on the roof, as shown in Fig. 1. The projections or lugs J J are then set into the notches or grooves in the arms E and secured therein by tightening the thumb-nuts I.

M is the sole-plate, which is provided with such means for securing it to the foot as are in ordinary use on skates. On the under side of this plate I provide a square projection, N, and I provide a corresponding socket, O, in the top of the sole-frame D, into which the projection N is adapted to fit. A screw-bolt, P, and thumb-nut Q, serve to secure the sole plate to the sole-frame and hold the square projection N in the socket O. The device shown in Fig. lis set to accommodate one who wishes to face toward the comb of the roof. When it is desired to face the other way, the soleplate M can be turned by loosening the nut Q and raising the projection N from its socket. It will be observed that the form of the projection N and its socket allows the sole-plate to be setto face toward either end or toward either side, as maybe desired. The form of the projection N and socket may be an octagon, or any equiangular form; but I believe a square will serve all necessary purposes.

R is the hinge securing the roof-frame and sole-frames together. S is the hinge which secures the segmental arms 0 to the roofframe A. j T U are means for fastening the sole-plate to the foot or shoe of the one using the device. A device similar to that shown in Fig. 1 is provided for each foot.

Vis the hole in the frame D through which the bolt P is passed.

Now, having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The roof-climbing device set forth, comprising the combination of the roof-frame A, having the downwardly-projecting frictionpoints B, the sole-frame D, hinged at one end to the frame A and provided with the downwardly-projecting segmental arms E, the segmental arms O, hinged to the roof-frame, means for clamping the arms 0 and arms E to each other, the sole-plate M, and means for securing the same to the foot.

2. The roof-climbing device set forth, com prising the combination of the frame A, having the frictiorrpoints B, the frame D O, hinged at one end to the frame A and provided at the other end with the arms E, having the slots G and notches L, the arms 0, hinged to the frame A and provided with the lugs J, the

bolts H and nuts I, the sole-plate M, provided for securing the plate to the foot, and the with the projection N, the bolt and 1111111) 1? Q, frameD,provided withthesocketOand holeV. and means for securin the plateMto t efoot.

3. In a roof-climbihg device substantially FREDERICK KRAMER 5 such as described, the combination set forth Witnesses:

of the sole-plate M, provided with the projec- J AS. R. TOWNSEND, tion N and bolt and nut P Q, and with means A. G. CONNER.
