Ohio, and
tors of said .lohn N. Helt- Application May 15, 1947, Serial No. 748,316 6 Claims. (Cl. 94-46) The present invention relates to improvements in apparatus for installing semi-plastic joint material in concrete and the like roads, and has for an object certain improvements over my prior Patents Nos. 1,946,972, granted February 13, 1934 and No. 1,982,387, granted November 27, 1934.
The present invention relates more particularly to improved methods and apparatus for installing joints in plastic concrete surfaces to keep pace with later developments in plastic sealing materials which have been produced for the forming and sealing of expansion and oontraction joints, in which the contraction joint vformed by the so-called dummy joint does not extend entirely through the thickness of the slab but which forms a plane of weakness for controlling the breaking of the concrete below the slab wherebyT the road which is laid as a monolith is divided along well defined and predetermined lines into a number of slabs separated by the expansion and contraction joints to enable the slabs to expand and contract relatively to one another.
The invention is useful in installing joints in plastic concrete surfaces such as revetments, roads, airports, etc., for the purpose of controlling or minimizing the cracking of the plastic material during the dehydration of such plastic material.
Among the new developments of joint sealing materials are substances which are semi-plastic and resist ow through the conventional joint installation devices in that these substances require comparatively great pressure to project the same through the mechanisms in order to form the proper section of joint material as it emerges from the installing device and into the plastic concrete of the road.
A primary object of the present invention is to provide an improved method and apparatus for dealing with semi-plastic materials in that the present invention provides a screw for developing enormous pressure to advance the semiplastic material through a hopper and ejection tube and to drive the same forcibly into the prepared groove in the concrete.
Another object of the invention is to provide in conjunction with the ejection installing mechanism groove forming and surfacing devices whereby the concrete in and around the installed joint may be immediately finished in a final manner.
Other objects of the invention are to improve the installing device and the apparatus for movably Asupporting the same upon the vcarriage whereby such installing device may be adjusted vertically and also has a longitudinal traverse on the main carriage to enable the same to move forwardly along the road while the main carriage remains stationary to perform its joint installing functions; and whereby subsequently the main carriage may be moved forwardly while the joint installing supplemental carriage remains stationary; all to the end of simplifying the installation of the new joint material in concrete roads and the consequent reduction in the expense of the same.
With the foregoing and other objects in view, the invention will be more fully described hereinafter and more particularly pointed out in the appended claims.
In the drawings, in which like parts are denoted by the same reference characters throughout the several views;
Figure 1 is a perspective view of a form of joint installing device constructed in accordance with the present invention and shown in connection with the concrete road under construction and with portions of a carriage traveling in the customary manner upon the side road forms;
Figure 2 is a vertical section taken through the hopper, worm tube, depositorand associated implements;
Figure 3 is a side elevational view of the joint installing device, with the supporting carriage diagrammatically illustrated;
Figure 4 is a vertical section taken through dual joint material depositors with lubricating means and grooving means associated therewith.
Referring more particularly to the drawings,
i I designates the main supporting carriage, which is supported as usual upon wheels 2 that travel on the side forms 3. Such construction is shown in my prior Patent 1,982,387 and is merely diavgramrnatically illustrated to show the supporting means for the joint installing device.
The main carriage may carry various implements for screeding, surfacing, compacting the road, forming grooves in which the joint material is to be installed, and various surfacing devices, all in accordance with common practice, some of which devices are 'disclosed in my above numbered prior patents.
One or more platforms carried bythe main carriage I are provided on which workmen may move and be supported to attend to the operations of the agenci'es'above referred to and the new joint installing device.
The joint installing device is slidable back and varracher.
along wheels 23`and21, the supplemental car= riage .25 being stationary. .This movement of the main carriage brings the supplemental carriage 25 again to a rear origin position upon the rails I9. This relative movement of the two carriages is permitted by the easy paying out vof the cable 29 from the windlass 39. Thus the main carriage is enabled to advance approximately ten feet ahead, performing its operations of screeding, surfacing, etc. as it moves. The main carriage is then again halted'and supplemental carriage 25 moved forward relatively thereto to resume its joint installing operation.
Referring more particularly to Figure 4, it may be important at times to lubricate the walls of the main chute. To accomplish this there is provided a lubricant holding chamber 9| which may be mounted on the main chute or worm tube 92. The lubricant 'in the chamber 9| is placed under pressure by the piston 93 operated by the hand wheel 99 through the screw shaft 95 turning in the stationary nut 9S. By rotating the hand Wheel 99 in a proper direction the screw shaft 95 is moved downwardly through the stationary nut 95 which forces the piston or plunger 93 downwardly in the receptacle 9|. This action forces the lubricating material through minute perforations in the perforated bottom plate 91 in the bottom of the receptacle 9| which forms a division between the lubricant receptacle 9| and the interior of the worm tube 92. The lubricant in small diameter multitudinous jets will be projected forcibly into the main chute and will lubricate the side walls of the chute so as to reduce the friction of the plastic filler material.
It may be desirable in some cases to project two different kinds of material into the concrete groove. In other words part of the groove may be filled with a semi-plastic material 98, which is forced from the main chute into the bottom part of the concrete groove. A less plastic material 99 is forced from an auxiliary hopper |09 by the screw threaded hand operated pressure screw |9|. A narrow tube |92 connects the bottom of the auxiliary hopper |90 with a discharge nozzle |93 arranged adjacent the mouth |04 of the depositor. Lubricant connections |05 are made to the lower portion of the inside walls of the auX- iliary hopper |99 and Alemite fittings |00 or other desired ttings are parts of the equipment of the connections |95 to enable lubricant to be forced into the auxiliary hopper |99. Such lubricant will reduce the resistance of the non-plastic material moving through the auxiliary hopper |99 and the tube |02 whereby such material may be more conveniently discharged into the top portion of the groove in the plastic concrete as indicated at 99. The lubricant chamber 9| and auxiliary hopper |09 and associated structure may be mounted on the chute in the modification of Figs. l and 2 if so desired, as illustrated in the drawings, and functions identically to the aforedesoribed function of these parts respecting the modification illustrated in Fig. 8.
It will be understood that by4 using two grades of material, that is the denser or less plastic material at the top of the groove, the same will permit the finishing tools to be operated over this semi-hard material and will also tend to confine the more plastic material in the bottom of the groove during the Various operations.
t is also understood that preliminary to the installing of the material the coarse aggregate is separated, as indicated at |91, by use of a grooving tool |08. This grooving tool |08 may 6.- be operated-byv'hand or otherwise fas-may be de. sired. The grooving tool `-isoperated-alongthe rack' or track |09 forming?A part of the carriage, rollers ||9 being shown ,as rolling along said track |99 and carrying the grooving tool |08. f
It will also be understoodthat the entire grooving and installing apparatus is mounted jon a movable carriage which spans the plastic surfacing structure. The track |99may be arranged so it is adjustable up and down as may be required.
While I have'disclosed herein the best form of the invention known to me at vthev present time, I desire it to be understood that Iv reserve theright to make changes and modications'in'the herein described embodiment of the invention provided such changes fall within the scope of the following claims. n v What I claim is: 1
