HEATlNG ATTACHMENT lFOR CULVERTS, 80C.

SPECIFICATION forming part of Letters Patent N o. 678,118, dated July 9, 1901. Application filed July 24,1900. Serial No. 24,692. (N0 modeli) T0 a/ZZ whom it may concern,.- i

Be it known that I, HERMAN O. KRUscHKE,

a citizen of the United States, residing at Auuse in connection with culverts and the like and so arranged with relation thereto as to insure an 'e`ective thawing out of ice andthe restablishment of a waterway therethrough.

While the invention is applicable to almostV any form of culvert or like structure in any location, still the same possesses special utility in connection with that class of culverts which are employed beneath road-beds. In nearly all northern localities during the winter the culverts beneath the road-beds become completely choked with ice,and frequently before the same areY thawed out in` warm weather and ajpassage-way restablished 4therethrough the water from the melting snows floods the road-bed and greatly impairs the same Vby washing gulleys therein. Other disastrous results arise' from the freezing up of the culverts or drain-tiles employed along highways; and it is therefore the pur'.-l pose of the present invention to provide ay simple, inexpensive, and effective heating attachment which may be utilized as apermanent fixture for a culvert or like structure, while at the same time providing convenient means for quickly and readily thawing out a sufficient portion of the ice therein to establish communication through the same.

With these and many other objects in view, which will more readily appear as the' nature of the invention is better understood, the same consists in the novel-construction and arrangement of attachmenthereinafter more fully described, illustrated, and claimed.

The essential features of the invention involved in the arrangement and peculiar mounting of the heating-pipe to permit of the `heating-pipe within the culvert.

the cold weather in northern climates.

self-adj ustment or falling thereof as the thawing progresses are necessarily susceptible to modification Without departing from the spirit orscope of the invention; but the preferred embodimentof the improvement is shown in Y the accompanying drawings, in which- Figure lis a general perspective view illustrating the application of the invention to an ordinary roadculvert and also illustrating one means of applying a heating agent to the Fig. 2 is a sectional view of a road bed and culvert,show ing a heating attachment applied thereto and embodying the present invention.

- Like numerals of reference designate 'corresponding parts in the several figures of the drawings.

In carrying out the present invention the form of the culvert is unimportant as well as themanner in which the same is used, as it will be understood that the heating attachment forming the subject-matter of this application may be utilized in connection with any of the, different types of culverts or simi- `lar structures which provide for the drainage of watertherethrough and which are exposed tothe weather, so that the same are subject to becoming readily choked with ice during However, for illustrative purposes there is shown inthe drawings an ordinaryculvert 1, arranged beneath the road-bed 2 and of the type which is usually constructedof plank, although it is obviousthatmasonry culverts,

as well as drain pipes and tiles, may be readily fitted with the heating attachment, which essentially involves the employment of the heating-pipe 3, which is arranged to be located inside of the culvert or like structure and to extend longitudinally thereof from end to end, as plainly shown in-Fig. 2 of the drawings.

In the adaptation of the heating-pipe to a culvert or drain of the general nature shown in Fig. 2 of the drawings it is necessary that the said pipe be provided atboth extremities thereof at the ends of the culvert or drain with the upstanding armsa, which are provided at their upper extremities with the screw closures or caps 5, which serve to keep the pipe in an open condition during the cold weather, so that when brought into use it is IOO only necessary to remove said closures or caps to provide for circulating the heating agent therethrough. The said upstanding arms 4 at the ends of the heating-pipe 3 project a sufficient distance above the culvert so as to obviate possibility of becoming flooded and embedded in the ice, which would thus destroy the efficiency of the attachment. ln order to insure the proper mounting of the heating-pipe attachment to facilitate the use thereof in thawing out the ice within the culvert or drain, the opstanding arms 4 are preferably arranged to work through supportingbrackets G, located at the ends of the culvert or drain. These supporting-brackets may be of any suitable shape or form and attached directly to the projecting ends of the closure or drain at the sides of the road-bed or sustained in a position independently thereof; but in connection with the type of culvert shown in the drawings the said supportingbracket-s 6 may be bolted or otherwise fastened directly to projecting end portions of the culvert, as plainly shown in Fig. 2 of the drawings. In any form of supporting-bracket that may be employed it is only necessary that the same be provided with the guide member 7, having an openingS therein loosely receiving the upstanding arms 4 of the heating-pipe, so as to permit such arms to freely slide therethrough.

ln connection with the supporting-bracket G for the end portions of the heating-pipe there are preferably employed adjusting-collars 9, fitting upon the upstanding arms 4 of the pipe and arranged above the guiding members 7 of the supporting-brackets, said adj usting-collars being fitted with set-screws l0, adapted to impinge upon the pipe-arms 4 to provide for holding the same stationary in an adjusted position, while also limiting the vertical play or movement of the main longitudinal portion of the pipe 3 within the culvert or drain. These details of construction, however, may be varied and suitable mechanical equivalents substituted so long as means are provided for supporting and guiding the pipe-arms 4 and also for holding the pipe fixed in an adjusted position.

Although the heating-pipe attachment may bein the nature of a permanent fixture to the culvert or drain, it is desirable in the fall, immediately preceding cold weather, to inspect the heating-pipe to ascertain if there is a free passage through the same, after which the closures or caps 5 are tightly fitted in position and the main longitudinal portion of the pipe drawn up against the roof of the culvert or drain, in which position it is held by adjusting the collars 9 so as to rest on the supporting bracket 6 and then tightening the set-screws l0. When the culvert or drain has become choked with ice and the season arrives when the same must be thawed out, the set-screws l0 are loosened, so as to release the pipe and make the same free to gravitate downward as the ice supporting it is thawed.

After freeing or releasing the heating-pipe, so that it may gravitate or float downward from the roof of the culvert or drain to the bottom thereof, both of the closures or caps 5 are removed and the heating agent introduced into one end of the pipe, so that it may readily iiow through the entire length thereof and out of its opposite end. This heating agent may be hot water or steam; but a convenient way of carrying the necessary heating agent from one culvert to the other is to mount a steam generator or boiler ll upon a wheeled truck l2 and to attach to the said generator or boiler a steam hose or pipe 13, which may be readily coupled to and removed from one of the upstanding arms 4 of the heating attachment. A continued supply of the heating agent to the pipe, so as to circulate the same throughout its entire length, necessarily causes the thawing of the ice about the pipe, and as the thawing progresses the said pipe will slide downward to the bottorn of the culvert or drain or may be arrested at any point desired by tightening the setscrews 10, it only being necessary that a suficient portion of the ice within the culvert be thawed to reestablish a passage-way therethrough and permit water to iiow through the same. When communication has once been restablished through the culvert or drain, the continued flow of water therethrough will necessarily complete the freeing of the same from the ice and snow.

It maybe desirable to provide the heatingpipe 3, at the juncture thereof with the upstanding arms 4, with suitable drain-cocks or equivalent devices 14, which can be utilized should it be necessary to draw off from the pipe water of condensation or other accumulations therein.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described heating attachment for culverts and the like will be readily apparent to those familiar with the art without further description, and it will be understood that various changes in the form, proportion, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-
