REAMING AND DRILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 481,418, dated August 23, 1892.

Application filed November 13, 1891- erial No. 411,823- (No model.)

To all whom it may concern:

Be it known that we, OLE O. OPSION and JUDSON V. HOOPER, citizens of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Beaming and Drilling Machines; and we do hereby declare the following to be a full,

' clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention has relation to improvements in drilling and reaming machines; and it consists in the peculiar construction, a certain novel combination, and the adaptation of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1 is an elevation of our improved machine. Fig. 2 is an enlarged view of the drill-carriage, together with the drilling or reaming spindle and the devices for adjusting and rotating the same; and Fig. 3 is a plan view of ourimproved machine.

In the said drawings similar letters of reference designate corresponding parts in the several views, referring to which A indicates the main pivot-hanger of our improved machine, to the lower end of which is fixedly connected a bearing-casting B, in which is j ournaled the drive-shaft 0, upon the extended end of which are fixed band-wheels a to receive the belt for driving the shafting of the machine.

Fixedly mounted upon the drive-shaft O intermediate the bearings thereof is a beveled gear-wheel d, which meshes with a similar horizontal gear-wheel e, fixed upon the upper end of the vertical shaftf, Which takes through the bottom of the casting B and through the curvilinear arm D at the inner end of the sweep E.

Fixed upon the lower end of the vertical shaft fis a beveled gear-wheel g, which meshes with a similar gear-wheel h, fixed upon the inner end of a shaft F, which preferably extends the full length of the sweep E and is journaled at its ends in suitable bearings thereon.

Arranged at various distances from the main or pivot hangerA are the approximatelyseinicircular hanger-tracks G, which are suitably hung from a roof or other point of ashop and are designed to assist in the support of the radial sweep E.

Adjustably connected to and extending upwardly from the sweep E, as better shown in Fig. l of the drawings, is a hanger-arm H, which is provided at its upper end with a wheel is, designed to travel upon the hangertracks G.

Fixedly connected with the travelingwheel It of the hanger H isa sprocket-wheel Z, around which takes an endless chain m, which is preferably of such a length as to extend down to within convenient reach of the operator, whereby it will be readily seen that the wheel it may be turned, and the sweep can be readily swung upon its pivot.

By the provision of the series of hangertracks G at various distances from the main or pivot hanger A it will be readily seen that the hanger H, which is adjustably connected to the sweep E, may be hung from the tracks at various distances from the pivot-hanger A, whereby the rim of the drill-carriage upon the sweep may be increased or diminished when desirable. By the provision of the series of tracks G it will be furtherperceived that the hanger Il may be connected to the sweep E at various points, soas to be adjacent to the movable drill-carriage and prevent undue strain upon said sweep and its connection to the main or pivot hanger.

Formed on the under side of the sweep E, adjacent to the sides thereof, as better shown in Fig. l of the drawings, are longitudinal racks i, which are designed to be engaged by vertical pinions j, mounted on a transverse shaft z, journaledin the drill-carriage M beneath the sweep E.

Keyed or feathered upon the transverse shaft z of the drill-carriage is a sprocketwheel N, around which takes a chain belt y, which extends down from the sweep to a point within convenient reach of the operator, whereby it will be seen that the drill-carriage may be readily moved along the sweep when desired.

As better illustrated in Fig. l of the drawings, the rotatable shaft F is keyed or feathered throughout its length, and keyed on said shaft is a longitudinally-adjustable beveled gear 92, which is suitably connected to the upper end of the drill-carriage M, which carriage is loosely mounted on the shaft F. The drill- 5 carriage M, which is preferably of the approximate form illustrated, comprises the mainbody portion q, the depending hanger r, and the lateral arm 8, extending from the lower end of said hanger.

Journaled in suitable bearings in the main body portion of the carriage M is a vertical tubular shaft N ,u pon the upper end of which is fixeda horizontal beveled gear P, which meshes with the gear n upon the shaft F. 15,, The tubular shaft N is provided on its inner side with a longitudinal feather t, designed to engage a longitudinal groove in the vertical shaft or spindle Q, which spindle extends down and takes through the lateral arms 801' 20. the carriage. This spindle or shaft Q is provided at its lower end with a key seat or socket, as illustrated, to receive the reaming or drilling, tool, and is provided at an intermediate point in its length witha peripheral z 5 groove to receive thelugs of a collar R,wl1ich is loosely mounted thereon. The collar R is provided at diametrically-opposite points with lateral trunnions u, upon which is. pivoted the spindle-governing lever S, which is provided with a middle opening and straddles the collar R, as shown.

Pivotally connected at one end to the end of the lateral arm 3 of the carriage-body is a link '1), which is pivotally connected at its opposite end to the lever S, which it serves to fulcrum.

Adjustably mounted upon one end of the lever S is a weight U, which serves in practice to normally hold the drill or reaming 4o spindle Q up out of an operative position, and loosely connected to and depending from the opposite end of said lever isahandle V, which extends down so as to be within convenient reach of the operator, who, by pulling said 5 handle, is enabled to move the spindle Q down into an operative position.

Adj ustably mounted on the sweep E, on op,- posite sides of the drill-carriage M, are the movable bearings W of the shaft F, which bearings are connected withthe drill-carriage by wire ropes w or the like, whereby it will be seen that they will be pulled and pushed by said carriage when the same is adjusted, and will prevent downward sagging of the shaft at the point where the drill-carriage is stopped.

In a machine such as described it will be readily perceived that the sweep E may be readily swung upon its pivot by an attendant standing upon the floor or ground, and by the provision of the series of tracks G, in conjunction with the hanger H, it will be seen that said hanger may be placed at various distances from the main or pivot hanger A, so as to increase or diminish the run of the drill-carriage, as described. For instance,

should it be desired to have thedrill-carriage run the full, length of the shaft F, the hanger 1 H would be connected to the outer end of the sweep E so that the wheel would travel upon the extreme outer hanger-track G. By'

mounting the drill-carriage M upon the shaft F and sweep E, as described, it will be seen that said carriage may be readily adjusted with respect to said shaft and sweep by an attendant upon the ground, and, through the medium of the depending handle V, it will be seen that the spindle Q, whichis normally held up out of operation by the weighted lever S, may be readily pulled down into operation.

Although we have specifically described the construction and relative arrangementlof the' several elements of our invention, yet we do not desire tobe confined to said construction, as such changes and modifications. may be made as fairly fall within the scope of our invention.

Having thus described our invention,.what we claim, and desire to secure by Letters Patent is-- 1: In a drilling and reaming machine, the combination, with a pivot-hanger, the sweep pivotally connected thereto, and the carriage adj ustably mounted on said sweep, of a series of approximate semicircular hanger-tracks arranged at various distances from the pivothanger, and a hanger carrying a traveling wheel at its upper end, adapted to engage the hanger-tracks and adj ustably connected at its lower end to the sweep, substantially as and for the purpose set forth.

2. In a drilling and reaming machine, the combination, with a pivot-hanger, the sweep pivotally connected thereto, the carriage adjustably mounted on said sweep, and the series of approximate semicircular hangertracks arranged at various distances from the pivot-hanger, of a hanger adj ustably connected to the sweep and carrying a traveling wheel adapted to engage, the hanger-tracks, a sprocket-wheel connected with said traveling wheel, and an endless chain taking around said sprocket-wheel and depending therefrom, substantially as specified.

3. In a drilling and reaming machine, the combination, with the sweep, the longitudinal feathered shaft mounted thereon, and the beveled gear keyed on said shaft, of the drillcarriage loosely mounted on the shaft and loosely connected to the gear thereon, the tubular shaft journaled in the carriage-body and carryinga beveled gear at its up or end, meshing with the gear on the shaft, t e spindle keyed or feathered in the, tubular shaft and having a key-seat at its lower end, a suitable means for normally holding the spindle up out of an operative position, and a suitable means for throwing said spindle down into an operative position, substantially as specified.

4. In a drilling and reaming machine, the
