BILLET-RECEIVING TABLE.

SPECIFICATION forming part of Letters Patent No. 445,293, dated January 27, 1891.

Application filed August 16, 1890- Serial No. 362,202. (No model.)

To all whom it may-concern.-

Be it known that I, FRANCIS I]. TREAT, residing at Chicago, Cook county, Illinois, have invented a new and useful Improvement in Receiving-Tables for Billets, of which the following is a specificaton.

The object of my invention is to provide for making a narrow substantial receivingtable for billets; and the invention consists in the features and combinations hereinafter described and claimed.

In the accmnpanying drawings, Figure 1 is a plan view of my improved billet-receiving table, parts being broken away to show the construction of the table; Fig. 2, a vertical longitudinal section taken in line 2 of Fig. 1, and Fig. a vertical cross-section taken in line of Fig. 1.

A is the receiving-table; B, the upper section thereof; C, the lower section thereof, and 0 bolts securing the two sections together; D, the rollers, and (l the shaftsthereof; E, cross-bars bridging the space between the rollers, and F gear mechanism for operating the rollers.

My receiving-table is of course so placed with reference to the shears that the cut billets fall down upon it before passing on to the conveyer to be carried to their place of final delivery.

The table is formed of two parts or seelions, one above the other. These sections are preferablysecured together by four bolts passing through lugs on the sides thereof, each of the bolts being threaded and having a. screw-nut on one of its ends. The upper section is preferably provided with side uards to prevent the displacement of the billets lying on the table. These side guards also operate as strengtheningbars for the upper section. The rollers are mounted loosely on shafts, and These shafts are held firmly between the upper and lower sections. The shafts are also pref erabl y formed with shoulders to prevent 1heir slipping endwise, so that being firmly held between the two sections and at the same time prevented from slipping endwise they are necessarily all. the time held securely in proper position.

The sections of the table, being bolted to gether, are of course detachable whenever it is desirable for any reason to take them apart. For instance, if one of the rollers should become broken or stuck on its shaft by clogging or otherwise, the nuts can be readily unscrewed, the bolts taken out, and the upper section of the table taken off. This renders the removal or repairing of the rollers an easy matter.

Another advantage of constructing the table in sections is that it enables the gearmechanism for operating the rollers to be placed in the middle of the table, the teeth of the gearing being flush with the surface of the rollers, thus making a combined roller and gear. This avoids the use of an external gear in position to interfere with the insertion of the table into the opening of the shearframe. Of course this does not apply to the first driving-roller of the table, which is secured to a shaft revolving in bearings upon the lower section of the table.

I claim- 1. In a reeeiving-table for billets, an upper section and a lower section detachably 'secured together, substantially as described.

2. In a receiving-table for billets, an upper section and a lower section meeting at the center line of the rollers and mechanism fordetachably securing the two sections together, substantially as described.

3. A receiving'table for billets, comprising an upper section, a lower section, rollers having their shafts clamped between the two sections, and mechanism for detachably securing the two sections together, substantially as described.

4. A receiving-table for billets, comprising an upper section, a lower section, rollers having their shafts clamped between the two sect ons, cross-bars bridging the spaces between the rollers, and bolts and nuts for securing the sections together, substantially as described.

5. In a receiving-table for billets, the combination of rollers and gear mechanism for operating the same, the gear mechanism being formed in the body of the rollers and having its teeth flush with the surface thereof, substantially as described.
