TUNNELDTG-GABRIAGE.

' Specification of Letters Patent.

Patented May 26, 1914.

Application filed August 18, 1910. Serial No. 577,854.

To all whom it may concern useful Improvements in Tunneling-Carriages, of which the following is a specificationr The object of this invention is to provide certain improvements in the construction, form and arrangement of the several'parts of a tunneling carriage ,whereby the results obtained'b the use of the improved car-- riage woul be materially improved.

This invention consists in a tunneling carriage comprising one or more of the following features: a truck, a beam pivoted to swing vertically thereon, a support movable along the beam and means for rigidly supporting the beam without the use of counterbalanced weights, said means comprising one or more braces arranged either to the front or to the rear of the pivotal connection of the beam on the truck or at both places, the brace or braces being arranged to be folded along the'beam for convenience in transportation and the said braces being also adjustable to suit diiferent places, the rear bracebein arranged tobeengaged with the roof 0 the tunnel and the front brace being arranged to be engaged with the floor of the tunnel.

A further object is to provide a tunneling carriage in which the support which travels along the'tilting-beam is arranged to carry a laterally swinging drill bar so that the drill bar may be swung into sub-,

stantial alinement with the beam for convenience in transportation, the support also being movable to a point over the truck for convenience in transportation. A practical embodiment of the invention is represented in the accompanying drawin s, in which igure 1 represents the carriage in side elevation with the parts shown in full lines in one of the operative positions of theicarriage and in dotted lines in anotherof its operative positions, the drills, drill bar and the drill bar support being shown in broken lines in their inoperative folded position over the truck, Fig. 2' is a top plan view of the carriage showing in full lines the parts in the position which they assume when the carriage is in operation, the drills, drill bar and the drill .barsupport being shown in broken lines in their folded position over the truck for purposes of transportation, Fig. 3 is-a detail view showing the drill bar support and the parts carried thereby inposition for undercutting, Fig. 4

port not being shown, Fig. 5 is a detail longitudinal vertical section through the carriage showing more clearly the means for moving the support outwardly and inwardly along its beam, and Fig.6 is a'detail transverse section taken in the plane of the line A-A of Fig. 1, looking in the direction of the arrows.

The tunneling carriage includes a truck 1* having traction wheels 2, whereby the carriage may be moved into and out of 0sition for use. This truck is provided with a pair of uprising side frames 3, between which the drill supporting beam is pivot ally mounted intermediate its ends, to swing vertically. This beam comprises two members 4 spaced apart, each of which is provided with outwardly extended flanges 5 along its top and bottom edges.

A suitable support, such as a drill bar' support 6, is fitted to move inwardly and outwardly along the front extension of the rear end of the beam, a pulley 10 is mounted. Between the side frames 3 of. the truck, be-

low the beam 4, a pulley 11 and a' winding drum 12 are mounted. This winding drum 12, in the present instance, is rotated by hand as followszThe shaft 13 of the winding drum is provided 'with'a spur gear 14:,

ble connection 13 leads from the support 6 is a rear end view of the carriage thesuparound the pulley 9 and from thence rearwardly around the pulley 11, one or more times around the drum 12, around the pulley 11, from thence rearwardly to and around the pulley 10 and from thence forwardly into engagement with the said support. In

the present instance, a drill bar 19 is shown.

tended to move the drill bar inwardly to a.

point over the carriage truck and fold the same into substantial alinement with the beam for purposes of transportation. A series of rock drills 21 are shown mounted on the drill bar 19 in the usual manner. An adjustable folding brace 22 is hinged at 23, at the endof the rear extension of the beam 4, which brace is provided at its outer end with afoot 24 arranged to engage the roof of the tunnel when the brace is swung upwardly into its operative position. This brace is further provided with an adjusting nut 25 for extending and contracting the brace for bringing it into and out of en agement with the roof and for holding the am in' its proper vertical adjustment. brace may be folded down into substantial alinement with the beam 4, for purposes of transportation. A similar adjustable folding brace 26 is hinged at 27, to the front extension of the beam 1, which brace is provided with a foot 28 arranged to be brought into and out of engagement with the floor of the tunnel by means of a nut 29. This nut 29 also serves to adjust the length of the brace 26 to coact with the brace 22 to rigidly hold the beam 4: in its desired adjustment. The adjustable brace 26 may be held in its folded position along the under side of the beam 4, as, for instance, by a. chain 30. Chains 31and 32 depending from the rear andfront extensions of the beam 4, are arranged to be engaged with brackets 33, 34, on the truck 1, when the parts are in their folded position ready for transportation, for the purpose of holding the beam against tilting on the truck. A clamp screw 35 is carried by the support 6 in position to clamp the support to and release it from the beam.

When the tunneling carriage is used in connection with a gang of rock drills, the operation is as follows: Presupposing the parts to be in their folded position, the carriage is moved into the proper position with respect to the work to be operated upon.- The chains 31 and 32 are released from their A engagement with the brackets 33, 34. The brace 22 is swung upwardly into a substantially vertical position and the brace 26 is released and swung downwardly into a sub- This stantially vertical position. These two braces are then adjusted one with respect to the other until the beam 4 has been brought into the'desired position. The drill bar is then swung around on its support until it assumes a position substantially at right angles to the beam 4. The screw clamp 35 is then released. The support is then moved outwardly along the front extension of the beam by the operation of the crank handle 17. When the suppoit reaches its desired position, it is locked there by the clamp screw 35. The extension feet 20 of the drill bar are then brought into engagement'with the side walls of the tunnel. When it is desired to transport the carriage to some other point, the

clamp screw 35 is released and the extension feet 20 of the drill bar 19 are released from their engagement with the side walls of the tunnel. The support 6 is moved inwardly into a position over the truck 1 and the support is secured in position by the clamp The drill bar is then swung around into substantial alinement with the beam 4:. The braces 22 and 26 are then released from their engagement with the roof and floor of the tunnel and folded along the beam 47. The chains 31 and 32 are engaged with the brackets 33, 34, on the true While .I have shown the tunneling carria'ge in connection with a gang of rock drills, it is to be understood that the support on the beam may be used for other purposes than for carrying rock drills. It is also evident that various changes might be resorted to 'in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention; hence I do not wish to limit myself strictly to the structure herein set forth, but
