specification.
My invention relates to improvements in 4 metal-planing machines whereby two surfaces 'slidefof the rigid post.
of an object can be planed at the same time and also the back movement of the-platen be much more rapid than the forward or cutting movement.
The invention is illustrated in the accompanying drawings, in which Figure 1 is a front view of the machine; Fig. 2 shows two views of the'cross-beam and the vertical slideway which projects down, from and at right angles to it. Fig. 3 is a side view showing the reversing mechanism. Fig. 4 is a top view of the machine.
The letter A designates the frame or bed, 7 B the reciprocating platen, and c the guides on which the platen moves; The mechanism for moving the platen will be described hereinafter.
Some of the features of this invention are applicable to ordinary two-post planers or to the open-side planer for which a patent was granted me May 29, 1883, No. 278,518.
The drawings show a rigid or permanent post D at one side of the frame A, a removable standard D being in the present. instance at the opposite side. By removing the standard D the cross-beam is wholly supported by rigid postD and the planer is converted into the open-side design.
The letter E designates the cross-beam, which is provided with a horizontal slideway e and is vertically adjustable on the vertical Integral with one end of this cross-beam is a downwardly-extending part E, having in its back a dovetailed groove f, fitting the said slideway f on the post, and on its front is provided with a vertical slideway e'-that is, the cross-beam E and the downwardlyextending slideway are in one solid piece and form a right angle, the said downwardly-projecting part serving to brace and sustain the cross-beam and insuring that the latter will preserve a true horizontal position when vertically adjusted.
the ordinary tool-holder. other tool-saddle I is mounted on the verti- I designates the tool head or saddle, which fits and moves laterally on the slideway e on the cross-beam. On this saddle is mounted (Not shown.) Ancal slideway e of the downwardly-extending part E. v
A triangular or oblique bracket L is attached by one end to the back of the crossbeam and the other end bears against a vertical slide h on the post D. This bracket braces the cross-beam against the strain of the tool while cutting.
The horizontal feed of the tool-head I on the cross-beam is accomplished by the usual shafts j h, which are rotated by the wellknown ratchet-box and pinion W and a vertical rack H. The said vertical rack has a rod 2', which has one end attached to a crankhead J on the end of a shaft K, which has a bearing Z at one side of the machine-frame and carries a sector friction-pulley N, driven first one way and then the opposite way by the driving-pulley O on the shaft It, which reverse at each movement of the platen B. A vertical screw-shaft 0 is in the vertical slideway e', and this screw is connected'with and controls the vertical movement of the toolhead I, which moves on the said vertical slideway. Mounted on the upper end of the said vertical screw-shaft 0 is a miter-pinion 0', which intermeshes with a corresponding miter-pinion p on one end of a horizontal shaft p, which has its bearing g on the vertical slideway. The portion of this shaft 19 that extends beyond the bearing is also, like the shafts j h, to receive and be rotated. by a ratchet-box and pinion, the same to be turned by the vertical rack H.
v The alternate reverse movement or rotation of the driving-pulley 0, previously referred to, is accomplished as follows: The shaft is, on which the pulley O is mounted, has two hearings P on the side of the machine-frame. Mounted loosely on this shaft is and between its bearings are a driving-pulley R, a large gear-wheel S, and a sliding double cone u to between the said driving-pulley R and gearwheel S. Rigidly secured on the shaft 7 0 is a bevel gear-wheel F, which connects with an other bevel-gear G on a diagonal shaft g, which extends under the platen B and imparts motion to the said platen by well-known connecting mechanismas, for instance, by the well-known worm-gear G shown in dotted lines in Fig. 4. The bearings P each have an arm m, which extends up and above the said 'drivingpulley R and gearwheel S. These arms afford bearings r for a shaft is, on which and between the bearings is rigidly mounted a driving-pulley R and a small gear-wheel S, which latter intermeshes with the'large gear-wheel S on the shaft 70. The two pulleys RR, mounted on the shafts 7c is, respectively, are driven by belts (not shown) and both are rotated in the same direction, as indicated by the arrows in Figs. 1 and 3. Fixed to the shaft on the side of the loose driving-pulley R toward the sliding double cone u'u/ is a friction clutch s to make connection with the pulley, and from this clutch extend two arms If on opposite sides of the shaft k. These arms, when forced apart by one end it of the double cone, cause the friction-clutch s to connect with the pulley R and thereby turn the said shaft 76. Fixed to the shaft 7a 011 the side of the large loose gearwheel S is a similar clutch .9, having two arms '0, which extend toward the other end it of the double cone and in similar manner cause the clutch s to connect with the loose gear-wheel S and turn the shaft 70. The function of the clutch-arms t in the one case and those 2; in the other is to be alternately forced apart by the sliding double cone u 11,. It will now be understood that when the sliding double cone is moved along the shaft 7r; toward the driving-pulley R, thereby spreading the two arms t, it will cause the friction-clutch s to grip the pulley R, which then rotates the shaft 70. Further,,the rigid bevel-wheel F on the same shaft beingconnccted through the bevel-wheel G and diagonal shaftg with the platen B,the latter will be moved toward one end of the machine. In the presentinstance this will be the back movement, which is more rapid than the forward movement. When the sliding double cone is moved along the shaft toward the loose gear-wheel S and the clutch 8' made to grip the latter, the shaft 70 will be rotated in an opposite direction and at a slower speed than when driven by the pulley R, for the reason that the small gear-wheel S of the shaft 10', which imparts motion to the large gear-wheel S, rotates in the same direction as the loose driving-pulley R; Theplaten B will therefore move in the forward or cutting direction at a slower speed than when moving in the backward direction, previously explained. The double cone, which controls the this purpose, which are operated by the moving platen. Thus it will be seen that the double cone is to be shifted alternately back and forth between the driving-pulley R and the gear-wheel S, and consequently the platen 13 caused to move backward and forward.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a metal-planer, the combination of the base or frame, a reciprocating platen, a post fixed rigidly at the side of the platen and having a vertical slideway f, and a cross-beam E, having at one end a downwardly-projecting part E, which fits the said vertical slideway of the post, as and for the purpose set forth.
2. In a metal-planer, a cross-beam provided with a horizontal slideway and having at one end a downwardly-projecting part provided with a vertical slideway for a tool-head, as set forth.
3. In a metal-planer, the combination of a cross-beam provided with a horizontal slideway and having at one end a downwardly-projecting part provided with a vertical slideway, a movable head I 011 the said horizontal slideway, and a movable head I on the vertical slideway, as set forth.
4. In a metal-planer, the combination of a cross-beam provided with a horizontal slideway and having at one end a downwardly-proj ect-ing part provided with a vertical slideway, a movable head I on the saidhorizontal slideway and a movable head I on the vertical slideway, screw-shafts on the cross-beam and a vertical screw on the downward-projecting part, said vertical screw having a miter-pinion 0', a horizontal shaft p, also having a miter-pinion, and a vertical rack H,- which imparts motion, as described, to the screw-shafts on the cross-beam and also the vertical screw on the downwardly-projecting part. i 5. In a metal-planer, the combination of the reciprocating laten, the diagonal shaft q to impart motion to the platen, a shaftk, provided with a bevel-gear which connects with the said diagonalshaft and also having a driving-pulley R and gear-wheel S, both loosely mounted on said shaft, a double clutch between the pulley and gear-wheel, a second shaft 70', having rigidly mounted thereon a driving-pulley R and a gear-wheel S, which latter is engaged with the said loose gearwheel, and means to actuate the said double clutch. 1
In testimony whereof I affix my signature in the presence of two witnesses.
