STREET-GAGE.

Specification of Letters Patent.

Patented Mar. 29, 1910.

Application filed June 5, 1909. Serial No. 500,455.

To all whom it may concern:

Be it known that I, PATRICK RoUoHnN, a citizen of the United States, and a resident of Fond du Lac, in the county of Fond du Lac and State of IVisconsin, have invented a certain new and useful Street-Gage, of which the following is a full, clear, and exact description.

The principal objects which the present invention has in view are: to provide a mechanical device to be used as a detector for inequalities in grading of a street pavement; to provide a device of the character specified wherein the height of the crown of a paved street may be mechanically adjusted; to provide a contrivance of the character specified, which is movably and guidably mounted on the street, to be readily shifted over the surface of the street; and to provide a mechanical contrivance for the purpose mentioned, capable of being adjusted to varying street widths.

One embodiment of the invention is disclosed in the construction illustrated in the accompanying drawings, wherein like characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of a gage constructed in conformity with the present invention, showing the same as in operative position on the surface of a street; Fig. 2 is a horizontal section taken on the line 2-2 in Fig. 1; Fig. 3 is a vertical section taken on the line 33 in Fig. 1; Fig. 41 is an enlarged detail, partly cut away to show the construction of the adjusting device for setting the gage; Fig. 5 is a horizontal section, taken on the line 5-5 in Fig. 4:; and Fig. 6 is a detail view of the mounting and housing of the carrying wheels for the gage.

The gage is built in two sections hingedly secured at 7, the hinge 7 being rigidly mounted upon laterally extended flanges of short masts 8. The masts 8 are formed from the two sections of angle iron, as shown particularly in Figs. 1 and 2 of the drawings. The mast sections are disposed vertically as shown, with one of the flanges of the angle iron from which said sections are formed being extended parallel with forms 9. The remaining flanges are mounted in the manner shown in Fig. 2, where they are brought together back to back, and when in operative position are secured by bolts and nuts 10. One of the two abutted flanges of the masts 8 is provided with an extension 11, to support a tie rod 12, which is secured to the forms 9 by being bolted thereto at 13. When the tie rod 12 is thus bolted into position, and extended over the extension 11, the forms which are secured to the mast sections by bolts 1 1 are held rigidly in an outstretched position such as shown in Fig. 1 of the drawings. The forms 9 are further secured to the masts 8 by truss rods 15. The rods 15 are bifurcated and secured to the forms by bolts 16, and at the top are passed through eared brackets 17. The brackets 17 may be adjusted lengthwise on the rods 15, so that the tension on the rods may be increased or diminished. This further compensates for any variation 1n the angle at which the forms 9 are extended from the masts 8. To provide for the variation of the angle of the extension of the forms 9, I increase the size of the bolt holes, or provide a slit if need be, in the forms 9 or in the flange of the mast to which they are secured, and wherein are mounted the bolts 14. I have not shown this construction in the drawings, for the reason that the variation is so slight at this point, as to be practically impossible of illustration 1n drawings such as accompany the present application.

The forms 9 are inserted within box-like end pieces 18, made from any suitable metal, perforated as at 19 to receive bolts 20, the forms 9 being provided with bolt holes to receive the bolts 20. \Vith such a construction, the end pieces 18 may be extended farther upon, or drawn out from, the forms 9. In practice, I construct the ends about three or four feet in length, which results in adjustable expansion, permissible to the gage, of six or eight feet. I am not limited to the length of the end pieces, and should the extension prove inadequate, I may readily adopt others of greater length. The end pieces 18 are rigidly secured to upright arms 21, upon which are fixedly secured brackets 22 Fig. 41 through a flange of which are passed bolts 23. The arms 21 are provided, with a. series of perforations to receive the bolts 2;), so that the brackets 22 may be adjusted lengthwise upon the arms 21, thereby accommodating an extension of the gage members to a greater depth than that illustrated in Fig. 1.

The brackets are provided with an enlarged end 2% Fig. 5 in which is provided a vertical screw threaded perforation, to receive in threaded engagement, an adjusting screw 25, provided with a hand wheel 26 by which the said screw is turned, and is also provided with a collar 27. The hand wheel is provided with an enlarged hub 28, and between the hub 28 and the collar 27 the ca 29 of a pipe standard 30 is held. The pipe standard 30 constructed from suitable piping, and is threaded at the top and bottom as shown particularly in Fig. 1- of the draw ings.

At the top the threads receive the cap 29, while at the bottom they are inserted within a screw threaded perforation in a truck bar 31. Each pipe standard 30 is of an internal diameter such as will neatly fit the enlarged end 24: of the bracket and is slotted lengthwise to pass the web of the bracket 22, said slot being shown in Figs. 1 and 5, where it is indicated by the numeral TV hen the screw 25 is in threaded engagement with the bracket 22, as shown in Fig. a of the drawings, wherein the hub 28 rests upon one side of the cap 29, and the collar 27 is secured rigidly to the screw 25 on the under side of the cap 29, any movement on the part of the screw 25 causes the bracket 22 to rise or fall in the standard 30, to rest upon the surface of the street. The weight of the forms 9 is carried upon the brackets 22 and the screws Mounted upon the brackets 22 by means of bolts 33, are the clamping aws 34 provided with solid body portions formed to fit snugly over the pipe standard 30. At the outer extremity the clamping aws 3 1 are held in operative relation by bolts 35. V

The operation of the clamping jaws 3st and the bolts 33 and 35 is as follows: When adjusting the forms to the grade furnished by the engineers, the screw 25 has been turned to cause the bracket 22 to travel up or down on the standard 30, and having arrived at the proper height, the bolts and 235 are drawn taut by the nuts with which they are provided, causing the body portions of the clamps 34: to bind hard upon the standard 30 and the sides of the arms 21, and thus render it impossible or exceedingly difficult to shift the position of the said arms, and the standard 30. A slight turn, or at most two turns, of the nuts upon these bolts, will at any time release the clamp upon the standard 30 sufliciently to permit the screws 25 to be rotated to raise or lower the arms 21 and the forms 9.

The truck bar 31 is extended transversely to the stretch of the forms 9 and is provided with rollers 36. mounted in the extreme ends of the truck bars 31. The rollers 36 are so disposed that they travel lengthwise of the street being graded.

Vith the gage thus constructed and mounted, it will be seen that it may be moved lengthwise of the street upon the rollers 36 with ease.

Extended crosswise from the truck bars 31 are fender bars 3'7 provided with rollers 38, pivotally mounted in the outer end there of. The fender bars 37 are suitably provided with a series of bolt holes 39, through which a bolt 10 passes, and by which the fender bars are secured to the truck bars By means of these series of holes, the fender bars 37 may be adjusted to lengthen or shorten their projection from the truck bars 31. The fender bars 37 are each pro vided. with a vertical extension 41, horizontally extended from which is a wheel 42. By this construction, should the gage line be set back of a guide member, the fender bars 37 may be placed over the guide members and the wheels 42 rest against the back of said guide member.

The outer sides of the standard 30 are provided with gage markings 43, by means of which the engineer in charge may set his instructions so that the mechanic in charge of the grading being done upon the street, can readily adjust the standards 30, to comply with the specifications of the engineer.

A feature in the present construction which has been worked out carefully is to provide a construction which may be readily and quickly knocked down. The masts 8 may be disconnected from the forms 9 by removing the bolts 14 and the brackets 17. The tie rod 12 is removed from the forms by releasing the bolts 13 and the truss rods 15 are removed from the forms by releasing the bolts 16. The forms are withdrawn from the end pieces 18 by removing the bolts 20 and withdrawing them from the said end pieces. In this condition, the masts 8 and the rods 15 and 12 and the two forms 9 are in a separated condition and may be packed together. The end pieces 18 are disn'lantled by withdrawing the standard 30 from engagement with the bracket 22, which is accomplished by removing the cap 29 from the said standard. The knockdown condition of the end pieces 18 would, in this condition, leave the truck bar 31 and the parts connected therewith, including the standard 30, in one part. while the ends 18 with the arms 21 would constitute the other part.

With an apparatus constructed as herein described, and as shown in the accompanying drawings, the operation is as follows: The form having had mounted thereon the end pieces 18 and connected parts, having been suspended from the masts 8, as shown in Fig. 1 of the drawings, the end pieces 18 are adjusted laterally on the forms 9 until the wheels 38 on the fenders 3'7 strike against the curb, or guiding member marking the full width of the street. In this po sition, the apparatus is moved along the length of the street, the forms 9 constituting the gage for the surface thereof. If the gage is to be used to determine the thickness of the pavement, this is accomplished by setting the forms up on the standards 30 to the required thickness for the body of the pavement, it being presumed that the wheels 35 are tracking in the gutter, or on the foundation of the pavement. As the apparatus is moved from point to point over the surface of the pavement, it is easy to detect any areas which are out of true.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
