LADDER ATTACHMENT FOR PIPES- Specification of Letters Patent.
Patented Jan. 9, 1906.
Application filed September 12, 1905. Serial No. 278,177.
To ML w/wm it may concern:
Be it known that 1, JOHN F. COLLINS, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Ladder Attachments for Pipes, of which the following is a specification.
This invention relates to improvements in ladder attachments for water-pipes; and its object is the production of a simple, inexpensive, and durable attachment for water-pipes and the like to facilitate the ascent and descent of inspectors or other persons to inspect, clean, or repair the pipes, valves, and thermostats usually employed in sprinkler systems and arranged along the ceilings of buildings, &c. The attachment may also be applied to stand-pipes and used as a fireescape; but it is primarily designed for interior use to render easily accessible parts out of reach from the floor.
WVith this end in view the invention consists in the novel construction, arrangement, and combination of parts to be hereinafter described, and particularly pointed out in the appended claims.
In the drawings, Figure 1 is a section through a portion of a building, showing part of a sprinkler system provided with my improved ladder attachment in side elevation. Fig. 2 is a view taken at a right angle to Fig. 1, showing the ladder attachment in front elevation. Fig. 3 is an enlarged horizontal section taken on line 0 y, Fig. 2. Fig. 4 is a vertical section through a portion of a pipe and the ladder attachment, taken on line 2 2, Fig. 3.
Referring to the drawings in detail, like numerals of reference refer to like parts in the several figures.
The numeral 1 designates the wall of a building, 2 a ceiling, and 3 a floor.
4 designates a sprinkler system having usually a pipe 5 extending to the ceiling and a pipe 6 along the ceiling. The pipe 6 is provided with one or more thermostatic-controlled sprinklers 7 of any practicable construction and a valve 8 controllin the flow of water through the pipe. The valve is usually within a few feet of the side wall, so that a ladder may be laced against the said wall for support, whic is to be ascended to reach the valve and other controlling parts of the system requiring attention.
As it is customary to inspect the. valves, thermostats, and sprinklers at stated intervals, usually weekly or oftener, I provide this attachment, which is applied to the pipe 5 to render the controlling parts of the system accessible at all times. Heretofore it has been necessary to carry a ladder from one room to the other and from one story to the other on the tour of inspection through the building.
My attachment comprises two verticallydisposed bars 10, arranged on opposite sides of the water-pipe and having laterally and oppositely extending rungs or steps 11, the rungs orsteps of one bar being on a plane be tween those of the other bar, thus rendering the ladder easy to ascend and descend. Each bar 10 is provided with eyes 12 at opposite ends, and surrounding the pipe are two c1amping-collars 13, formed in two parts 14 15, having each apertured outstanding lugs 16, between which the ends of the bars 10 are secured. Bolts 17 are passed through said lugs and through the eyes at the ends of the bars 10, and nuts 18 threaded onto said bolts serve to securely clamp the bars between the collar and the latter to the pipe.
It is apparent from the foregoing that the bars 10 with the pipe 5 constitute a perfect ladder and that by extending the same from a point about eighteen inches above the floor to a point within three feet of the ceiling only a very short attachment is necessary to render the same convenient to ascend and the controlling parts of the water system accessible.
Having thus described my invention,what I claim is 1. The combination with a pipe, of two clamping-collars having perforated lugs, a bar having an eye at each end adapted to be held between said lugs and having also laterally extending rungs, and bolts passing through said lugs and the eyes of said bar to clamp the collar to the pipe and to clamp the bar between said lugs.
2. The combination with a pipe, of two clamping-collars formed each in two parts having outstanding lugs, two bars arranged on opposite sides of the pipe and having eyes at their ends, said bars having also oppositelyextending rungs, and bolts passing through said lu s and the eyes of said bars to clamp said collars to the pipe and to clamp the bars between the lugs on said collars.
3. The combination with a pipe, of two In testimonywhereoflhave affixedmysigclamping-collars on said pipe, and two bars nature in the presence of two subscribing Witarranged on opposite sides of said pipe and nesses.
having their ends secured to said collars, said JOHN F. COLLINS. 5 bars having laterally-extending rungs and Witnesses:
the rungs on one bar being on planes between E. B. COLLINS,
the rungs of the other bar. EMIL NEUHART.
