MEANS AND METHOD O11 RECONDITIONINCT DAMIAGED STEPS.

Application flledlFebruary 15, 1924, Serial 110,693,119.

and Methods of Reconditioning Damaged Steps, of which the following is a specifica tion. 1

This invention relates generally to the recondit oning of brokenand damagedsteps on the stoops of buildings, or otherwise 10 cated, the invention being intended more particularly-for appl cation and use in corn nection with the reconditioning and repairmg of cement or concrete steps.

The invention has fora general ob ect to provide a novel and improved means and method for reconditioning the damaged steps, repairing broken corners and "edges thereof,.and resurfacingthe tread of the step.

For further comprehension of the inven tion, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing,

and to the appended claimsxin which the various novel features of the invention are more particularly set forth; I j V Fig. 10f the drawing is a perspective view, with parts brokenawa-y, showing the application of the invention to the reconditioning of a cement step.

Fig. 2 is a transverse, vertical sectional. view of the step, this view being taken on the line 2-2 of F ig. 1, the adjacent upper step being shown in end elevation, r

According to my invention I provide a,

frame member which is adapted to extend around the top edge ofthe broken or damaged step at the front and ends thereof.

This frame member preferably in the form of a channel iron,the size of the chan- 'nel between the flanges being determined by the sizeof the projecting edging at the top of the step, the width of the channel being somewhat greater than the depth of the edging, while the depth of the channel is preferably somewhat greater than the width or overhang of tl1e,saidedging; This'chan-" nel iron frame element comprises the main 1 central member 10 which, when is position extends along the front of the step, and the end members.10'*which are turned at right angles to the mam'member and extend along the ends of the step. At the extremities of the drawing.

'these' end members the channeled frame 'member is turned parallel to the main length thereof to form short extensions 10" which engage the rear side of the edging.

where the latter projects longitudinally beyond the end wall of the vertical element or riser of the step.

Fixed at one end to the main length 10 of the channeled member are several hookbolts 12, whileflthe' end members 10" each have a like hool:-bolt 12 fixed thereto These bolts are of slightly less length than the width of the step, and project transfversely with respect to the members towhich they are'attached into the space within the frame. ,These bolts inaybe conveniently riveted at one end tothe frame memflanges of the frame member will engage closely under the pro ecting element consti tuted by the edging of the step.

In carrying out the reconditioning of the step with my improved means and according to my invention a number of holes or sockets are formed in the tread 18 of the step in proper position to receive the hooked ends 14 of the various hook-bolts when the frame is fitted on the edging 19 of the step. The frame is then sprung into place on the stepand completely surrounds the edging thereof, the bolts 12, 12 extending over the tread of the step and having their hooked ends is engaged in the sockets formed in the latter. The tread of the step is then faced with a filler or layer 20 of cement of a color to match that of the step, the thickness of [this layer of cement being such as to bring its top surface flush with the top edge of the metal frame. The cement thus fills the portion of the frame proje ting beyond the step, extending downward in front of the edging of the step as indicated in Fig. 2 of After the cement has hardened the channel frame is painted a color to match the cement and the reconditioning of the step is complete. The step, when thus reconditioned is in all respects like a new step, while, in addition, further breaking or damage at the edges or corners thereof is prevented by the protecting metal frame.

Having thus described my invention what I claim as new and desireto protect by Letters Patent of the United States is as follows 1. A device for use in reconditioning steps comprising a channeled frame member arranged to surround the edging of a step, and a number of hook-bolts fixed to said frame at one end andextending within the confines of the frame, said hook-bolts having their other ends turned downwardly.

2. A device for use in recoiri itioning steps comprising; a channeled frame member arranged to surround the edging of a step, and a number of hook-bolts fixed to said frame at one end and extending; within the confines of the frame, said hook-bolts having their other ends turned downwardly, said frame being of a depth between its flanges somewhat greater than the depth of the edging of the step to which said memberis to be applied and having said hook-bolts attached thereto at points below its top edge.

3, A device for use in reconditioning steps comprising a channeled frame member arranged to surround the edging of a step, and a number of hook-bolts fixed to said frame at one end and extending within the confines of the frame, said hook-bolts having their other ends turned downwardly, said frame being of a depth, between its flanges somewhat greater than the depth of the edging of the step to which said member is to be applied, said bolts being spaced above the lower flange of theframe member a distance equal to the depth of the edging of the step to which the frame is to be applied.

a A reconditioned cement step having; a channeled frame extending around the edging of the step with its bottom flange extending under and abutting against the bottom of the step edging, and its top flange extending over said edging and spaced above the tread of the step, a number of bolts fixed to said frame and extending across the tread of the step, said bolts having hooked ends engaging in sockets in said tread, and a cement facing on said tread flush as its top with the top edge of the said frame.
