like with removable sectional blocks,

A further object ofmy invention is to provide closure blocks of the same or analogous material as'th'efroad bed, and of such shape as to be jambed into the trench and there sealedto complete the road bed.

A still further object of my invention is to provide for protecting the pipes in such trenches from cold and also for the ready removal of the closure blocks for gaining access to said pipes. I

1 forth and With these ends in view, this invention consists inthe details of construction and combination of elements hereinafter set specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe itsconstruction in detail, referring by numerals ;tothe accompanying drawings forming a part of this application, in which:

Fig. 1 is a plan in perspective of a number of city streets showing the method of embedding pipes and the like in trenches; in

one direction the trenches being continuous while in the cross wise direction these trenches are shown as sectional or in parquet form. 1

2. V r F ig. 1 is a perspective view of one of the Fig. 5 is a section-similar to Fig. 3 showing the trench lined with cork or similar ma.-.

terial .providing yielding surfaces for the closure blocks when inserted inzthe trench.

In carrying out my invention as herein embodied, 10 representsthe road bed conbeds in continuous lengths, the closure blocks structed of well-known material such as concrete or cement, andin the construction of such road beds where they are relatively thin an increased thickness may be provided throughout certain lines as indicated at 11 for the formation of the trenches 12 of suflicient depth to properly protect the pipes or is a section on then-line 33 of cables 13 laid within said trenches. These trenches are preferably formed when the road bed is being laid and may be either continuous as indicated at 12 in Fig. 1 or in sections or parquet form as indicated at12f as may best suit the conditionsfor which th pipes or cables are to serve. The trenches 12 have-their side walls inclined inward from top to bottom'fo'r the proper reception of the wedge-shape closure blocks "14, which blocks are preferably made of the same or substantially the same material of which the road bed is made, so that when these" blocks are fitted within thetrenches, as shown in Figs. 1 and 3, they will be wedged thereinin suchmanner as to sustain the weight of traffic over the road'bed without bringing undue pressure to bear upon the pipes or cables; and in practice, the walls of the trenches have applied thereto asphaltummaterial ina hot or 'liquidstate, so that when the'closure blocks are wedged within thesetrnches, a water-tight union is formed between the road bed and the clo-' sure'blocks, leaving the surfaceof'the road bed in a smooth and unbroken condition.

By this method, not only are the pipes or cable within the trenches protected against the elements and the road bed left in a perfect condition, but access maybe readily-had to the pipes or cables by applying suflicient heat to the road bed and blocks adjacent to I the trench to sufficiently soften the as'phal tum to permit the removal of one or more of the block s. ;To facilitate the removal of these blocks, two eyes 15 are set in each block so that lifting hooks may be insertedin-said' eyes for drawing theblocks upward; the eyes being below the surface of'the blocks by be ing set in the depressions 16 and these depressions in practice will be filled with asphaltum inorder to complete the surface:

of the block and give the normal appearance to theroa'dbed, butthe asphaltum in these depressions may be sufliciently softened by the application ofheat to. enable theeyes to. be engaged bysuitable-lifting hooks. Where thetrenches are formed in the road are set therein end against end and sealed in the" same manner utilized in sea-ling the side surfaces of the blocks as just described. Where the trenches are made in sections or in parquet form, each length of the trench v snugly fits therein and all of the abutting surfaces of such blocks aresealed to the corresponding surfaces of the road bed, the seal ing material being indicated at 17 in Figs. 2 and 3.

trenches for the special protection of 1 the pipes or cables laid therein, I utilize layers of cork or similar material 18 as shown in; Fig. 5, and when such lining is used, not

Lion, these disadvantages are entirely overcome and a cheap and simple methodis provlded for laying and covermg such plpes or cables, and yet giving ready access to ,the

same throughout vtheir lengths and without inany way m urmgor marrmg the appear-v ance of the surface of the road bed; flhis is of great, importance,,especially in road beds extending throughoutcountry districts, and also forcity streets. 1 e i -V 'In practice, I have found it desirable toform a echannel-wlay 1,9 in the bottom surface ofeach of the closure blocks for partially enclosing the'pipe'or cable laid within the trench.

: When pipes and the likehave been laid by my improved system and it becomes nec-. essary or desirable to gain access thereto for removal, renewal or repair, such access is.

readily hadat any, point throughout the length ofthe trench by simply removing the required number of closure blocks in "the manner before described, and when the repa1r work has been accomplished, the blocks maybe again ,relaid leaving the road bed ;in perfect condition; and; this feature is of great importance in connection with crowd 1 like within the trenches, blocks for closing ed city streets. V .e Of course. I do not wishto be limited to theexact' details of construction as herein lgsho'wn, ,as these may be variedwithin, the limit-s of,,the appended claims without departing from the spirit of my invention;
