and inexpensive means for sealingthe joints of underground conduits to retain the con-` duit-sections in line and to prevent the entrance of moisture at the joints thereof.
vMy inventionconsists inthe construction, arrangement, and combination ofthe various `parts of the` conduit-sealing device and 1n my improved method of sealing conduit-3 joints, as hereinafter, more fully set forth,
pointed vout in my claims, and illustrated in the accompanying drawings, in which Figure 1 Shows a perspective view! of a number ofconduit-sections in line with my improved sealing devicein position adjacent to'one of the joints and 'also showing .a iinished joint. Fig. 2 shows an inverted perspective view of one of the cores'with the retaining-Sheet holders connected therewith. Fig. 3 shows a perspective view of samein a diiierent. position.- Fig. 4 shows a top or plan view of a number of conduit-sections in line with each other with my improved sealing device adjacent to one of the joints and -two retaining-sheets adjacent to Vanother joint, and Fig. 5 shows av longitudinal-sectional view of a modiiied Aform'of core and retaining-sheet. j
Referring. to the accompanying drawings, the reference-numeral 10.'is used to indicate the conduit-sections. In use th'ese 'sections are preferably placed in line upon a' concrete or other base 11, the base projecting outwardly beyond the sides ofthe conduit-sections. The ends of the sections are placed as close together as possible, and I provide for sealing these vends to hold the sections in line and also to prevent the entranceof moisture by means of the following devices.
The numeral 12 indicates a core, preferably of segmental shape and tapered slightly fromits upper to its lower end.V The length of the core is slightly greater than the height of a conduit-section, so that when placed in position adjacent to the side'of a conduit-section it will project above it. Secured to the topof the core 12 is a metal strap 13, having a handle 14 formed therein. The ends of the metal strap- 13 project downwardly parallel with the side edges of the core and'form the retaining-sheet-holdingv arms 15. Said arms projectjdownwardly to a point adjaapart slightlygfrompthe adjacent side edges of thevcore.`
The numeral 1 6 indicates a retaining-sheet which may or may not be necessary, dependinguponthev soilwhich is tov be used. This sheet isofsubstantially the same height as the core and is of a length somewhat greater than the width ofthe core. The sheet may be made of thin metal or of pasteboard or any similar ineXpensivematerial.
In use andassuming thattwo conduit-sections were'placed upon a basefll in line with eachother andwith their ends adjacent, then two cores4 12v'are provided and a retainin ysheet 16 is placed withl its 4central portion a jacent to the convex side of the core and its end portions projected through between the side edges of the core and the arms 15. Then .one core with its retaining-sheet is placed upon each side ofthe conduit-sections, the bottom of the core resting on the base 11, and the flat face ofthe core and the end edge portions ofthe retaining-sheet are placed against the side of the conduit-sections adjacent to Patented March 13, 19C 6.
A.6o cent to the bottom of the core, and are spaced"A the point between two sections. Then the opl erator places earth or other packing material against the outer face of the retaining-sheet up to a point about level with the top of the conduit-sections, and this `earth is packed in firmly around ythe retaining-sheet After this is done the operator grasps the handle 13 of the core and drawsv the core and its arms 15 upwardly, thus leaving the retaining-sheet in position with'its central portion spaced apart from the adjacent part of the conduit-section. The tightly-packed earth holds the retaining-sheet firmly in position after the core is removed. Then the operator fills the space between the retaining- Sheet and the conduit-sections with a composition including cement or other material that will solidify and seal the conduit-joint. Then the top portion of the joint between the two conduit-sections is covered with the same substance and rounded off in substantially the manner shown to the right of Fig. 1. The retaining-sheets will rest in position and serve to hold the sealing substance in position and prevent it from becoming broken or misplaced when the process of filling earth around the conduits is being completed.

providing retaining-sheets of this kind the operator may fill up around the conduit-sections as soon as the joints are sealed, and he need not wait for the sealing substance to solidify, as the retaining-sheets form protectors to securely hold the sealing substance in position. A cheap grade of pasteboard has been found suitable for the purpose of `forming the retaining-sheets.
In Fig. 5 of the drawings I have shown a slight modiiication in the form of the core. At the top of the core 12 the outer central face ofthe core is projected outwardly and upwardly at 17 and the retaining-sheet is formed with a similar outward and upward projection 18. When this form of retainingsheet and core is used, the top portion 18 of the retaining-sheet forms a guide to direct the sealing substance into the opening between the retaining-sheet and the conduitsections, thus enabling an operator to readily and quickly shovel the sealing substance into the opening, and the top of the retainingsheet serves to direct all of the sealing substanceto position within the retaining-sheet.
Having thusdescribed my invention, what I claim, and desire to secure by Letters Patent ofthe United States therefor, is-
1. In a conduit sealing device, a core formed with one face shaped to lie flat against the sides of two abutting conduit-sections, a retaining-sheet fitted to the opposite side of the core With its edge margins shaped to lie flat against the sides of the conduit-sections beyond the core, and means for detachably securing the sheet to the core.
2. In a conduit-sealing device, a core, and arms secured to the top of the core and spaced apart from the body of the core.
3. In a conduit-sealing device, a core, and arms secured to the core projecting parallel with and adjacent to the side edges thereof.
- 4. In a conduit-sealing device, the combination of a core and a strap secured to the top ofthe core, having a handle formed on its central portion, and arms formed on its ends, projecting parallel with and adjacent to the side edges ofthe core.
5. In a conduit-sealing device, a core. tapered slightly from its upper to its lower end and segmental in cross-section, and a strap secured to its top having a handle formed at its central portion, and arms formed on its ends projecting parallel with and adjacent to the side edges of the core.
6. In a conduit-sealing device, a core formed with one face shaped to lie ilat against the sides of two abutting conduit-sections, a retaining-sheet iitted to the opposite side of the core with its edge margins shaped to lic ilat against the sides of the conduit-sections beyond the core and means carried by 'the core for detachably securing the retainingsheet to the core.
7 In a conduit-sealing device, a core, arms secured to the top of the core and spaced apart Jfrom the body ofthe core, and a retaining-sheet passed around the outer face of the core with its end portions projected `through between the core and the arms.
8, In a conduit-sealing device, a core, and arms secured to the core projecting parallel with and adjacent to the side edges thereof, and aretaining-sheet passed around the outer face of the core with its end portions projected between the core and the arms.
9. The method of sealing conduit-joints, which consists in iirst placing a core and a retaining-sheet adjacent to a joint in a conduit, then packing earth or other iiller iirmly against the exterior of the sheet, then removing the core, and finally filling the space between the sheet and conduit with a cementitious substance.

l0. The method of sealing conduit-joints, which consists in plac ng a core and a retaining-sheet adjacent to a conduit-joint, said core holding the retaining-sheet spaced apart from the conduit-joint, then placing a iiller against the outer surface of the retainingsheet to support it in position, then removing the core and leaving the sheet in position spaced apart from the conduit and braced by the iller, and iinally inserting between the sheet and conduit a cementitious substance.
