7 3 Claims. (01. 33-474) My invention relates to improvements in gauging apparatus for use by builders, carpenters, masons, and'the like, in erecting cylindricaltower-like structures, particularly silos.

The principal object of my invention is to provide simply constructed, inexpensive apparatus which may be quickly and easily erected for convenient use to gauge the inside diameter of silos and like structures by progressive steps, upwardly, as the structures are erected, so that the walls may be built up symmetrically and perpendicularly, or inwardly inclined, as desired, and which is adapted tobe easily taken apart for storage, tra'nsportation,- or other similar purposes.

Other and subordinate objects are also comprehended by my invention, all of which, together with the precise nature of my improvements, will be readily understood when the succeeding description and claims are read with reference to the drawings'accompanying and forming part of this specification.

In said drawings: V

Figure 9 is a view in transverse section taken on the line 9-9 of Figure 2 and drawn to an enlarged scale, and

Figure 10 is a view in perspective of parts of one of the guy members.

Referring to the drawings by numerals, my improved gauging apparatus has been illustrated therein, by way of exemplification of a preferred practice of the invention, as erected on the circular floor I of the usual silo, the circular block wall 2 of which, as shown in part, is constructed of the usual concrete blocks 3 laid in break joint rows.

The basic element of my improved gauging ap paratus comprises a center pole, or mast, 4 of tubular form which, preferably, is formed of pipe sections 5 detachably connected by-the usual threaded couplings 6. The sections 5 are provided with end apertures 8 therein forming tool holds for use in coupling the sections 5 together by means of a suitable tool. The pole 4 is designed to be erected to a height substantially greater than the contemplated height of the silo, and the uppermost section 5 is provided with a cap flange 9 for the attachmentof guy members l0 thereto. The pole 4 is centered in the floor El by means of a tubular plug l0 suitably wedged into a center hole II provided in said floor,.the plug fitting into one end ofthe lowermost'pipe section 5. 1

The guy members l0 comprise cables 12' suitably attached, as at l3, to the cap-flange 9'and connected at their lower ends by adjustable lo'ops M to chain sections [5 adapted-to be connected to flat hooks I'G suitably attached, as at I'L'to the tops of short'postsl8 driven into the" ground aroundthe silo location in substantially degree angular'relation around the same, and ap proximately equidistantly spaced apart andfrom the center of the floor 'l. 'The posts l8 may be suitably braced, as at IS; The loops M are rendered adjustable by "suitable clamps M. The poled may be set exactly vertical with the aid of the usual plumb bob, not shown, and the guy members l0 tightened to maintain the pole in place.

A pair of upper and lower, extensible brace bars 20, 2| are provided for bracing the pole against bending and maintaining the same in the axis of the silo as-the structure is built up. The bars 20, 2| extend diametrically of the pole, and the wall 2, and each comprises a center section 22 adapted to be secured to the pole by a clip 23 and bolts 24, and a pair of end sections 25 endwise slidable on the center section into set positions in which said sections engage the inner face of the wall 2. Guide clips 26 .on the sections 22 slidably mount the end sections 25 on the center sections and longitudinal slots 21 in the end sections, together with bolts 28 on the center sections 22, provide for setting the latter. As will be clear, the bars 20, 2| are vertically adjustable on the pole 4 in selected set positions b means of clips 23 and bolts 24, so that said bars may be slid upwardly on the pole 4 into selected positions as the wall 2 rises. Also, said bars 20, 2| are rotatably adjustable about the rotatably fit the pole 4, and a cross-arm 32 on said yoke. The gauge arm 29 slidably extends through horizontally aligned clips 33 onthe yoke 30 and on the cross-arm 32, respectively. 0n the gauge 'arm 29 is an outer end section 34 hinged thereto, as at 34, to swing in one direction about a vertical axis when the silo wall 2 is out of round, and also for folding to shorten the gauge arm when desired. A vertical gauge fingerraiis pivoted, as at 36, to the outer end of the section for swinging adjustment-on the finger 8:5 mm vertical or'difierent inclined posi- 21710115 established 'by a-set screw-36in said finger, and an=arcuate-slot31 in said :section '34. The gaugefinger 335, when :vertical, forms :a straight edgesfor wiping against rowsof blocks 3 to 'determine when the same .areproperly set, :or for rbearingfiagainst a :block in "one row to form a guide for laying a block in ma higher row. .As will be understood, the 'gauge arm .29 may be slidably 'set 'in th clips 33., :34 :for diflierentdiamaster and radius-gauging operations.

n'islida-ble :clip 36 is provided on the pole 4 beneath the yoke 30 forsumziorting the 1 yoke and which is-des-i-gnedifor vertical adjustment along the pole 4 to sustain the yoke and arm -29-at different-levels. Theclip' Iii-may be of any-"suitable feonstruction-adapted :for tightening around pole4, or loosening, 'by manipulation'of bolts The :ioregoing WiIL-itis'beIieved, su'fiice toim- :parta clear understanding of my. invention, since the use .of the apparatus and parts i has beenset .forth in connection with the description of the structure thereof.

Manifestly, the invention, as described-is susceptible of modification without :departing'irom =the inventiveeoncept, and right .is herein reserved to. such modifications as fall within the scope of :the'appended claims.

What I claim is:

1. In apparatus for use in erecting a circular wall, a pole adapted to be arranged in upright position in the axis of said wall, a U-shaped yoke extending laterally from said pole and having ends rotatably and slidably mounted on said pole, an upright brace bar fixed to the yoke, a gauge arm adapted to extend horizontally from said yoke and having an inner endportion slidably mounted .on said :yoke .and'ibrace bar, respectively, a straight edge finger, and means to mount said finger on said gauge arm at the outer end thereof in upright position and for lateral swinging movement about an axis perpendicular to the axis of said gauge arm.
