UNTTE THOMAS FITZGERALD, OF FREDONIA, NEW YORK.

JOINT-FILLING MACHINE.

Specification of Letters Patent.

Patented Feb. 11, 1913.

Application filed October 10, 1910. Serial No. 586,147.

T 0 'all rv/ 10m it may concern Be it known that I,- THOMAS FITZGERALD, a citizen of the United States, residing at F redonia, in the county of Chautauqua and State of New York. have invented a new and useful Improvement in Joint-Filling Machinesof which the following is a specification.

This invention relates to improvements in portable machines or devices of the sort disclosed in my Patent No. 805,719, dated November 7, 1905, which are used in the.

construction of pavements for pouring melt- -ed tar, pitch or other analogous binding or not required in order to properly direct the material into the crevices; and also to make provision for adjusting the discharge spouts to adapt the machine or device for use on pavements in which the crevices are differently spaced.

For the sake of brevity and clearness, the filling material will be hereinafter referred to as tar but it will be understood that any suitable filling or binding material can be used.

The. machine or device comprises an inner holding vessel for the tar provided with one or more discharge spouts and arranged in an outer vessel or casing furnished with a burner for heating the tar vessel and discharge spout to keep the tar in a liquid condition and insuring a free discharge thereof. The outer vessel or casing is mounted on a wheeled truck or carriage adapted to be pushed over the pavement,'and the inner vessel isv hung'or movably supported in the outer casing so that the discharge spout is capable of being shifted laterally so as to be always held directly over the crevice by a guiding wheel or device arranged to travel in the crevice and control the position of the spout. Means are provided for controlling the discharge of the material as required and for raising andlowering the guide device out of and into operative position. When the machine is furnished with a plurality of discharge spouts for simultaneously filling two or more crevices, the

spouts and their guide devices are made adjustable to suit differently spacedjcre'vices and valves are provided for independently controlling the discharge of the tar from the several spouts.

In the accompanying drawings, consisting of three sheets: Figure 1 is a side elevation, partly in section, of a multiple spout pouring machine embodying the invention. Fig. 2 is a longitudinal sectional elevation thereof. Fig. 3 is a plan view thereof. Fig. tis a fragmentary transverse sectional elevation on'an enlarged scale. Fig. 5 is an enlarged plan view, partly in section, of the spout guiding devices. Fig. 6 is a section of the adjusting means for the guide wheels. Fig. 7 is an enlarged section of one of the pivotal supports for the inner vessel. Fig. 8 is an enlarged fragmentary section of one of the discharge spouts and valves. Fig.

9 is an enlarged fragmentary side elevation, partly in section, of a single spout machine.

Fig. 10 is a transverse sectional elevationv thereof.

Like reference characters refer to like parts in the several figures. a

A represents an outer vessel, tank or casing of any suitable construction which is supported by or constitutes a part of a truck or carriage having wheels B whereby the machine or device can be moved along over the pavement. Inv the construction shown,

the casing A, which consists of an uprightmetal cylinder having an open upper end, is provided at opposite sides with stud axles or trunnions Z; on which the wheels B are journaled.

C represents, push handles which are secured to and project rearwardly from brackets 0 to which the axles are secured. The handles are preferably offset or bent toward one side of the machine so that the operator in pushing the machine can walk at one side of the crevices being filled by the machine and thus avoid stepping on'the soft tar. v

D represents the inner tank or vessel which contains the tar and which is provided with one or more discharge spouts depending from the lower end thereof through the bottom of the outer casing, and which is movably supported in the outer casing A so that it is free to shift laterally. For instance, the inner vessel is pivotally supported by screws d secured to the upper portion of the outer casing at the front and rear thereof and passing through holes in the depending rim of a flange cl which projects outwardly from the upper end of the inner vessel over the upper edge of the outer casing. In the machine illustrated in Figs. 1-8, two discharge spouts E are provided for simultaneously filling two crevices,

.while in the machine shown in Figs. 9 and 10 only one spout is provided. The bottom of the inner vessel preferably inclines downwardlytoward the discharge spout or spouts to facilitate the discharge of the tar. By thus hanging or mounting the inner vessel in the outer casing, the lower end thereof is adapted'to be shifted sidewise so that the discharge spout or spouts can be guided by suitable means to follow or be held always directly over the crevice or crevices to direct the tar thereinto as the machine is moved along. I

The discharge spouts E are secured to the .inner vessel in any suitable way which enables them to be adjusted toward or from each other to suit differently spaced crevices. For instance,the spouts are secured to slides e which are adjustable in a guideway e on the bottom of the inner vessel D by means of adjusting screws 6 which project out through the outer casing A.

The means shown for guiding the discharge spouts comprise front guide wheels F and a rear guide wheel F, there being one front guide wheel for each spout arranged in front of the spout to travel in the crevice into which the spout pours the tar. The rear guide wheel F is preferably located in rear of the outer casing A where it can be readily seen by the operator and kept in one of the crevices of the pavement to facilitate the guiding of the machine. This wheel is arranged to travel in one of the crevices at one side of the crevices into which the spouts discharge and therefore does not roll in the freshly discharged tar. In the construction shown, see particularly Figs. 46, the guide wheels are adjustably mounted on a frame f which is secured at its front end to a spring plate f attached to the bottom of the outer casing A and to which the discharge spouts E are adjustably fastened. The front guide wheels are journaled on an axle f seated at its ends in hollow adjusting screws f which are screwed into threaded holes in the side.

bars of the frame The guide wheels F are held against the inner ends of the adjusting screws f by a spring f surrounding the axle between the wheels, so that the wheels will be moved apart by unscrewing the adjusting screws f and moved nearer together by screwing in the adjusting screws. The adjusting screws are held, when adjusted, by jam-nuts f. The guide wheels can thus be adjusted correspondingly to the discharge spouts when the latter are ad-' justed to fill crevices which are differently spaced. The discharge spouts are secured to the side bars of the frame f by adjustable eye-bolts f which permit the described adjustments of the spouts but hold them rigid with the frame f when adjusted. The rear guide'wheel' F is journaled on one end of an axle f" which is adjustably secured at its opposite end to one of the side bars of the frame f by nuts f and passes through a bearing hole in the other side bar of the frame. As the discharge spouts are connected by the'frame f to the guide wheels they will be caused to follow in the paths traversed by the front guide wheels F, and as these guide wheels travel in the crevices to be filled they act to hold the spouts directly over the crevices. There is sufficient looseness or play between the parts of the machine to allow the movement of the spouts necessary for them to accommodate themselves to the ordinary irregularities of the crevices.

By movably mounting or hanging the inner vessel in the outer casing as described, rigid discharge spouts can be employed which are desirable as they have no joints which are liable to become clogged by the tar.

G, Fig. 2, represents a lever or handle for moving the frame f to lift the guide wheels. out of or lower them into operative position. This lever, in the machine shown, is pivoted on one of the handle bars C and is connected by a rod 9 to a bell-crank lever g which is fulcrumed on the handle bar and is connected by a rod or link 7 to the rear end of one of the side bars of the frame f. I

g is a hook or device adapted to be engaged by the lever G for holding the guide wheels in their elevated. position. Any other suitable means can be employed for raising and lowering the guide wheels.

H represents a valve with which each discharge spout is provided for regulating the discharge of the tar. The valve shown is connected to the lower end of a rod h which is pivoted at its upper end to a bell-crank lever h fulcrumed on the upper portion of the. inner vessel D and is connected by a rod 71. to an operating lever or handle lbs. The valve operating lever k for one valve is preferably fulcrumed on one of the Push handles C of the machine, while the operating lever k for the other valve is similarly fulcrumed on the other push handle of-the machine, so that the levers can be readily operated by the fingers without removing of the inner vessel and'the discharge spouts.

The hot gases ascend through the space 2' between the vertical walls of the inner vessel and casing, the latter thus serving as a heating jacket for the inner vessel and facilitating the heating of the inner vessel and its contents. The burner is supplied with fuel by a pipe 75' from a suitable reservoir 2' located in any convenient position on the machine. Any other suitable means for heating the inner vessel can be used. The filling material is ordinarily poured into the inner vessel D in a melted orliquid condition and it is only necessary to supply heat enough by the burner I to keep the material hot and in a liquid state.

K represents a strainer or screen of any suitable kind through which the material is poured into the inner vessel for removing therefrom any solid particles or foreign matter.

The invention, in so far as the described manner of movably. mounting the containing vessel and guiding the discharge spouts is concerned, is notrestricted to the'use of the outer casing or heat jacket, and on the other hand, discharge spouts of different construction and other means for guiding the spouts can be used in connection with an inner vessel arranged in an outer casing provided with means for heating the inner vessel.
