ARIVEOB-PLATE-SETTING DEVICE.

Specification of Letters Patent.

Application filed January 7,1915. Serial No. 916.

To'all whom it may concern:

Be it known that I, THOMAS H. KANE, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented a new and useful Armor-Plate-Setting Device, of which the following is a specificaion.

This invention relates to a device for setting armor plates for the expansion joints between the sections ofa concrete roadway; and its object is to provide a device of this nature whereby the armor plates may be accurately and conveniently set with their upper edges in the crown of the roadway. This object is accomplished by a beam adapted to be supported a sufficient distance above the finished level of the roadway to permit the workmen to finish the surface of the roadway beneath this'beam, togetherwith clamps mounted on this beam for holding the arm plates at the, exact height clesired, and means for vertically adjusting the clamps.

This invention consists in the novel details of construction shown in the accompanying drawings, described in the following specification and particularly pointed out in the claims.

In the drawings Figure 1 is a cross section of a road showing one embodiment of my armorplate supporting device in position.

Fig. 2 is a cross section of the main supporting beam on a larger scale, showing one of theclamping devices in engagement with a pair of armor-plates. Fig. 3 is an elevation of: the supporting device at right angles to Fig.2. Fig. 4: is a. perspective, view of the main portion of this supporting device.

Fig. 5 is a perspective view of the pivoted jaw portion of this supporting device. Fig. 6" is a perspective view of the locking mem-' her for the pivoted jaw. Fig. 7 is a perspective view of a preferred embodiment; of m'y'invention. F ig; 8 is a perspective view (taken from the side opposite to that shown in Fig. 7) showing the armor-platesand spacing strips in position. Fig. 9 is a View similar to Fig. 8 but taken from the opposite side.

Similar reference characters refer to like parts throughout the several views.

- Referring especially to Figs. 1 to 6, inclusive, the armor-plate supporting-device is positioned above the road bed 1 by supporting the main T beam 2 on stakes 3 or other rigid members, at such a height that trowels or other tools can freely pass below this beam to'finish the surface of the concrete constituting the roadway 4. At intervals along the beam, its flanges 5 are perforated to permit the halves of the shank 6'to pass through. A nut 7 on each shank determines the distance of the jaws below the beam 1. At the lower end of the shank isa jaw' 8 having a groove 9 to receive the flange 10 at the upper edge of the armorplate 11. A hole 13 through the ear 14 re ceives a pin 15 which supports the pivoted jaw 16. A second hole 17 receives a. pin 18 on which the locking member is supported, which consists of the side arms 19 and the cross bar 20. The armor-plates are bent, if

necessary, to the exact curve to be given the surface of'the roadway. The shanks 6 are inserted in the holes in the flanges -5 of the beam, the lower flange or portion 22 of the beam extending through the slots 2;) in the shanks and preventing turning of the supporting devices which are positioned by means of the nuts 7. The armor-plates 11 are then paired with proper spacing strips 24, preferably of felt or tar-paper, between them, and then placed between the jaws (5 and 16. The locking members are then swung to" the position shown in solid lines in Fig. 2, resulting in the cross bars 20 forcing the pivoted jaws 16 against the armor-plates and locking them in position. The beam 2 and the armor-plates are then placed on the supports 3 and concrete is filled in on both sides of the arm-plates. After the concrete has set sufliciently to support the plates which occurs in a very short time, the clamps are swungfto the position shown in dotted lines in Fig. 2 which permits the beam and clamps to be removed. If desired, the ro'adwaymay be finished before or after the supporting device is removed, the distance the beam'2 is above the roadway permitting tools to pass beneath it.

The construction thus far specifically de- Patented Feb. 1, 1916,

scribed comprises a clamping member having a pivoted jaw; the same objects may, however, be more satisfactorily attained by using a sliding jaw clamp. As indicated in Figs. 7, 8 and 9, the latter may consist of a fixed jaw 30 and a movable jaw 31, said movable jaw being preferably provided with a shank 3:2 rigid therewith and slidable transversely through an opening in the fixed jaw. It will be understood that the fixed jaw may be notched at 33 and the movable jaw at 34- to receive the flanges 10 of the armor-plate 11 as before. The shank 32 may be slotted to receive the cross-sliding wedge 35 which, in one position, allows the armorplates 11 and spacing strip 2st to be inserted, and, in another position, clamps them tightly together. Projections 36 may be formed on the wedge to prevent it from being lost, and its smaller end may be inclined abruptly at 87 to allow the clamp to be fully opened quickly and to save material. The adjustment of the shank 6 in respect to the supporting bar 5 may be secured as before by a nut 38, that is shown provided with cars 39 that may be struck by a hammer or other tool; and the bar 5 in this case is slotted below the upper flange to receive a lock-nut 40, similar to nut 38, whereby the threaded shank 6 may be readily secured in any position of adjustment. Tt will'be clear that the same feature may be applied to the construction shown in Figs. 1 to 6, inclusive.

In practice, the device shown in Figs. 7, 8

and 9 has proven more satisfactory than that first described, as concrete is less apt to get into the parts. The manner of using the device is, of course, substantially the same as previously pointed out.

Many changes may be made in the proportions and details of this supporting device without departing from the spirit of my invention.
