SHAPING-MACHINE.

Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed April 13, 190A. Serial No. 202,9 L3.

To all whom it may concern:

Be it known that I, JAMES C. STEEN, acitizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented a certain new and useful Improvement in Shaping-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of my specification.

My invention relates to shaping-machines, and more particularly to that class of shapingmachines having a traveling head or carriage. It may be applied to one having either one or two carriages.

The object of my invention is to produce a shaping-machine of the class described with the traveling head or carriage so constructed and arranged and the feeding mechanism so related thereto that the ram may be adjusted to travel at any horizontal angle with the direction of travel of the carriage without in any way interfering with the horizontal feed or travel of the carriage along the bed of the machine.

The various advantages of my improvement will appear as I proceed with my specification.

In the drawings, Figure 1 is a top plan view showing the traveling head or carriage and one end of the bed or frame of the machine. Fig. 2 is a side elevation, and Fig. 3 is a front elevation, of the same. Fig. 4 is a top plan view of the carriage with the parts resting thereon removed and broken away in several places to show details of gearing. Fig. 5 is a vertical section on the line 4 4 of Fig. 4. Fig. 6 is a partial vertical section through the housing of the shaft N, as indicated by the line 6 6 in Fig. 1. Fig. 7 is a vertical section through the carriage on the line 7 7 of Fig. 4. Fig. 8 is a section on the line 8 8 of Fig. 5, showing the gears, sleeve, ratchet, and ratchet-lever in elevation. Fig. 9 is avertical section through the carriage on the line 9 9 of Fig. A, and Fig. 10 is a detail on a large scale of the adjusting-sleeve e.

A is the bed-plate and frame of the machine. B is the table, and Cthe carriage, these parts being of the usual construction.

Supported on suitable bearings near the top of the frame are the screws A A, upon which work the nuts attached to the carriages, by which the same are caused to travel backward and forward over the frame in the-usual manner. The carriage Csupports a revoluble saddle D, which carries the ram, the drivingarm, the motor, and the various mechanisms by which the parts on the saddle are operated. The upper face of the carriage and the lower face of the saddle D are milled down so as to present bearing-surfaces to each other, and are provided with annular keyways C (see Fig. 9) in which fits an annular key C, which serves to center thesaddle D and maintain its axis of rotation constant. The upper face of the carriage C is also provided with an annular T-slot c, in which lit the heads of bolts 0, which pass through holes in the saddle D and which are provided with nuts 0', by means of which the saddle D is locked securely in any horizontal angular position.

E is the ram, which travels in guideways E on the saddle D in the usual manner.

The power for driving the mechanism is obtained from a motor F, which is in any suitable manner supported on and secured to the saddle D.

G is the controller-box, and G a hand-wheel governing the same.

The motor, through gears H H and a set of variable speed-gears J, J, J, and J, the

shaft K, and the pinion K, all suitably supaccomplished by the following mechanism:'

The end of the motor-shaft F is provided with a spiral gear M, which engages with another spiral gear M, keyed to a shaft N. The shaft N has its bearing at one end in the housing M which is supported on the bracket N, in which housing the motor-shaft also has bearing and which covers in the spiral gears M M. The other end of the shaft N has its bearing in a housing N, supported onthe saddle D. A spiral gear 0 is there loosely mounted on the shaft N (see Figs. 5, 6, and 8,) said spiral gear having a long hub O, which projects through the housing and has clutch-teeth adapted to be engaged by similar teeth on clutch O, which is splined to N and adapted to be engaged with or disengaged from the hub O by mechanism to be described later. Journaled in the housing N below the gear O is a short shaft P, having keyed to it at one end a spiral gear P, engaging the spiral gear O, and at the other end a spurgear P, engaging a spur-gear P, keyed to a shaft P. The spur-gear P engages spurgear Q, keyed to a shaft Q, journaled in the plate D, and a second spur-gear Q is keyed to said shaft Q and engages a spur-gear R, keyed to a shaft R, which is supported in suitable bearings from the saddle D and which carries atits other end a spiral gear R. (See Figs. 4:, 7 and 9.) The latter engages a spiral gear S, keyed to a short vertical shaft S, which is supported in the carriage G with its axis coincident with the axis of rotation of the saddle D and carries at its lower end on the under side of the carriage a mitergear S. A horizontal shaft T is hung below the carriage and is provided at one end with a mitergear T, engaging the miter-gear S,'and at the other end with a spur-gear T, which engages a spurgear T on the usual nut U, through which the screw A works and which is secured to the under side of the carriage in the usual manner. It is thus apparent that when the clutch O is caused to engage with thehub O of the gear 0 that the rotation of the motor-shaft will be communicated through the spiral gears 1 M to the shaft N, thence through the spiral gears O P, the shaft P, the spur-gears P, P, and Q, the shaft Q, the spur-gears Q R, the shaft R, the spiralgears R S, the vertical shaft S, coincident with the axis of rotation of the plate D, through the bevel-gears S T, the shaft T and the spur-gear T to the spur-gear T on the nut U, which is thus caused to rotate and travel on the screw A and carry with it the carriage. It is also apparent that asthe shaft S is in the axis of rotation of the saddle D the carriage may be moved with the saddle D in any horizontal angular position without throwing out or disarranging any of the gearing above described.

=When it is desired to feed the tool, as when it is doing work, the clutch O is disengaged, which leaves the spiral gear 0 free to turn loosely on the shaft N, the rotation of that shaft then having no effect on said gear. The feeding mechanism is then driven through the shaft P and the spur-gear P in the following manner: The shaft P is prolonged beyond the housing N, where it has keyed to it a ratchet-wheel c. A sleeve 0 is loosely mounted on a boss on the housing N, which forms the bearing of the shaft P, and said sleeve is provided with a projecting flange 6, (see Figs. 1, 3 and detail 10,) which has a portion of its circumference cut away, as illustrated in Fig. 10. Said flange e is adjacent to the ratchet-wheel e and is adapted to be engaged by a pin 6, carried by a springcontrolled pawl f, pivoted to a rocker-arm g",- which is journaled on the shaft P". The sleeve is milledexcept for ashort di'st'ance from its endnearest the housing N,Where it is smooth and is provided with a notch f, adapted to be clutched by a detent on one arm f of a bell-crank lever f, which is pivoted to an extension of the housing N". The other arm f is pivotally connected to a segment f which bears in an annular groove f in the clutch O". The handle f operates the bell crank lever f. It is apparent that the ratchet-wheel 6 can only be engaged by the pawl f when the sleeve 6 isso turned that the pin 6 bears upon that partof the flange'e which is cut away and'that the effective throw of the pawl can be readily controlled by means of this sleeve, this being the usual construction and forming no part of this invention. The notch f is in such a position with reference to the cut-away portion of the flange c that it can only be engaged by the detent on the arm f of the bell-crankf when the sleeve 6 is in position to prevent the pawl f from engaging the ratchet-wheel-e. The bell-crank lever f can be thrown-so as to cause the clutch O to engage the sleeve 0' only when the notch f is in a position to receive the detent on the arm f of the bellcrank lever. Therefore one mechanism can not be thrown in until the other is made completely inoperative. The rocker-arm g is rocked in the usual manner by a pitman h, pivotally connected to and operated by the crank k, secured to the driving-arm L in the usual manner.

My invention and also its operation will be understood from this description.

I do not wish to limit myselfto the exact detailsof construction, as it is apparent that other gearing may be substituted for that shown and described. The construction as shown permits the saddle to beadjusted at any horizontal angular position withoutin any way interfering with the longitudinal travel of the carriage, and thecarriage may be fed along the bed either rapidly, as through the shaft N, or intermittently, as when-feed ing through the driving arm L, entirely indedependent of the horizontal angle of the saddle to the bed. The bell-crank-lever f also provides a safety device for throwing; either one of these driving mechanisms into operation and is so constructed that when one is in the other is out, thus preventing any-possibility of breakage.

Having thus described myinventi'on, what I desire to claim asnewand to cover by Letters Patent is 1. In a shaping-machine, in combination with the bed-plate, feed-screw, rotatable nut thereon, and traveling carriage',a rotatable saddle bearing on said carriage, means for looking said saddle in anyangular position', the
