DRILLING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 780,695, dated January 24, 1905.
Application filed December 21, 1903. Serial No. 186,097.
To rr-ZZ whom, it WI/CLZ/ concern:
Be it known that I, ALEXANDER W. WHITE- FORD, a citizen of the United States, residing at Omaha, in the county of Douglas and Stateof Nebraska, have inventedcertain new and useful Improvements in Drilling-Machines, of which the following is a specification.
This invention provides a drill of novel formation for utilization of compressed air or other fluid medium as the motive agent, the tool being operated by engines of the oscillatory type, each arranged to supplement the action of the other. Oompactness in the arrangement of the parts is an essential feature in the construction of the engine, as well as the relative location of the crank-shaft and. tool-stock, whereby it is possible to employ an ejector for forcibly removing the tool with the greatest ease and despatch. For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached.
While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a top view of a drilling-machine embodying the invention. Fig. 2 is a side View thereof, the cap-plate being removed and the tool-stock in section. Fig; 3 is a detail view of the valve-plate as seen from the upper side. Fig. 4 is a view of the valve-plate as seen from the inner side. Fig. 5 is a longitudinal section of the tool-stock, ejector, mountings therefor, and the adj unctive parts. Fig. 6 is adetail perspective view of the means for connecting the piston-rod to the crankshaft.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by thesame reference characters.
The drill is designed most especially for utilizing compressed air as the motive me- .tial manner.
dium. However,steam or other compressible fluid may constitute the motive agent.- 5 The frameworkfor supporting the operating parts may be of any design, according to the capacity and style of the machine. The frame comprises, essentially, a cap-plate 1 and a valve-plate 2, spaced apart the required dis- 55 tance and connected by ties 3 in any substan- The plates 1 and 2 are provided with corresponding openings to constitute bearings for the several parts, and these open ings are reinforced by outwardly-projected bosses, as indicated most clearly in Figs. 1 and 5.
The motive power for operating the toolstock is derived from companion engines 4 of the oscillating type, provided at opposite sides 5 I with trunnions suitably mounted in bearings of the plates 1 and 2. The valve-plate 2 is provided with the inlet-ports 5 and exhaust-ports 6, with which the ports 7 of the engines alternately register in the well-known manner. The 7 cylinders are pressed against the valve-plate so as to maintain a steam-tight joint and prevent waste of the motive power. The piston-rods 8 are connected to the crank portion of the crankshaft 9 by the coupling 10, which is composed of companion interlocking parts, the ends being threaded and longitudinally split and supplied with clamp-nuts 11 for contracting or binding the ends of the coupling upon the threaded ends of the piston-rods after the 8 parts have been connected. The crank-shaft 9 is journaled at its ends in bearings of the plates 1 and 2 and is located at onecorner of the frame, the diagonally opposite corner receiving the tool-stock 12. A pinion 13 is se- 5 cured to an end portion of the crank-shaft and meshes with the gear-wheel14 on the shaft 15, paralleling the crank-shaft and tool-stock and journaled at its ends in the plates 1 and 2. A gear-wheel 16 of less diameter than the 9 gear-wheel 14 is keyed to the shaft 15 and meshes with the gear-wheel17, secured to the tool-stock 12, so as to rotate therewith. By having the tool-stock and the crank-shaft located at diagonally opposite corners of the frame the parts are compactly arranged and screw 22, provided at its inner end with a point 23 to be brought into forcible contact with the inner end of the drill or tool 2&, so as to remove the same from the tool-stock when required. The inner end of the bearing-sleeve 18 is enlarged to form a cup 25, in which are located balls 26, arranged to travel upon a cone 27, cooperating with the toolstock and gear-Wheel 17 so as to sustain the gnchthrust incident to the operation of the The compressed air or other motive agent is supplied to the engine and exhausted therefrom in the manner well understood in the operation of engines of the oscillating type, and the power developed is transmitted directly to the crank-shaft by means of the piston-rods 8 and from said crank-shaft to the tool-stock by means of the intermediate gearing, substantially as herein disclosed, thereby imparting rotation to the drill or other tool applied to the stock or holder 12.
Having thus described the invention, what is claimed as new is In a drill, the combination of spaced plates, a tool-stock journaled therebetween and having a cone, a bearing-sleeve for the tool-stock having a cup at its inner end and a flange near its outer end, a clamp-nut having a flange acting jointly with the flange of the bearingsleeve to clamp one of the aforesaid plates and threaded to said bearing-sleeve, balls arranged between the cone and cup of the toolstock and bearing-sleeve, and a pressure-screw threaded into the clamp-nut and having a point at its inner end for engagement with the tool to be ejected, substantially as specified.
In testimony whereofI aflix my signature in presence of two witnesses.
