IMPROVEMENT lN PLANlNG-MACHINES.

Specification forming part of Letters Patent hlm-"99,157, dated January 25, 1870.; reissue No. 6,17 1 dated v*December l5, 18V-1f7 application led July 15,1874.

To allJ whom ib may concern' out' the working parts of the machine. Formed Be it known that we, 7ILSONA W. CAREY on or attached to the front and back parts of and GEORGE W. HARRIS, both of Lowell, in the table c and b, are suitable stands h and j, the county of Middlesex andI State of Massawhich work in slides, and are controlled by ohusetts, have invented new and useful Imguide screws or pins k la, as shown in Fig. `2 provements in Planing-hlachines; and We dol of the drawings. These stands h and j, at hereby declare that the following is a full and their lower parts, are furnished with a socket exact description thereof, reference being had and nut, in which operate the collar l and to the accompanying drawings, and-to the letscrew m, by means of the hand-wheel n, such ters of reference marked thereon. enabling au operator todepress the front part The nature of our invention in planing-mal c vof the table, and elevate the back part b. chines consist-s in a bed-piece or table, formed thereof simultaneously, thus keeping the surin two parts, each of which is pivoted at the faces of the same always parallel or in paral-v same distance from the center of the cylinder, lel planes. Located and secured to the back with cutters, they (the said parts) being so oppart of the frame c are suitableboxes, in which erated, by a screw, as to depress the front Operates the counter-feed shaft o, on one end part and elevate the back part of the table of which is secured Vthe driving and driven vfeed-pulleys P and P. Attached to this shaft, and operating on the same, is the swinging frame q q, in which is mounted the pressure feed-rolls q q, the frame being provided with the intermediate shaft 1', which is furnished with a pulley, r'. This pulley connects with lthe driving feed-pulley l? by means of the belt s, the feed-rolls q q' receiving motion from the shaft r by means 'of the gears s s' s', the required `pressure being produced, when the rolls are inoperation, by means of the sprin gs t t, or weights.y

lri using our improved planing-machine as a surface-planer the feed-rolls q' q', by aid of, the swinging frames q q, are placed in position, as shown in Figs. 2 and 3 of the drawings,

of the same parallel to and with each other. 1t further relates to the device for removing thepressure feed-rolls, as hereinafter described. It further relates to the combination of an adjustable gage or rest, substantially as hereinafter described, with the table or tables, and the planing-cylinder. l

To enable others skilled in the art to make and use our invention we will proceedto describe its construction and operation.

Figure 1 represents a plan of our improved planing-machine. Fig. 2 is a view of the 'back end, with parts of the frame removed; Fig. 3, a Side elevation; Fig. 4, a longitudinal section.

Similar letters in the different figures indicate corresponding parts.

In the construction of our improved plancutters i t', as may be desired, the required attached or secured to the frame U by means` of the pivots or bearings d d and ye e, on which they operate. Both parts of the bed-piece a and b, swinging on the pivots d dand e e, are edges may be true and even with the surface located the Same exact distance from the cenof the back part ly of the table, the 'operator ter of the cylinder f, which cylinder is prois enabled to regulate the cut or chip to be re vided with bearings working in boxes, they moved from the material at will, by aid ofthe being adjustable. Said cylinder also has cuthand-wheel n and screw m, by which he can tersi i in the usual manner, they being addepress the front part a and elevate the back justed and secured to the cylinder f So that the part b of the table, without altering their parcutting-edges of such cutters mayrun true and allel position with each other. Thus, during rolls q q by means of the springs t t or weights. The cutters it' on the cylinder f, having prewhich brin gs them in contact with the material lto be planed, thus feeding it toward .the

amount of vpressure being given to the feedviously been adjusted so that their cuttingproperly wi h the surface of the back, part b the entire operation of planing the material,

of the table. g representsthe driven pulley, the full u nplaned surface thereof comes n1' confrom which motion is communicated throughtact with and Slides on the back part b of the e good, Whether the chip to be removed is heavy or light.

When our improved device is used for edgth ing, squaring, taking out of' wind, beveling, and other purposes, the feed-rolls g g are removed from the table a and b Vby means of the swinging frame q q, as shown in Fig. 1 of the drawings, the same being swung over the back part b of the table;

ble rest is secured to the table, land the guide t is adjusted in any position, angle, or bevelv required, as shown 1n Fig. 2 of the drawings. This adjustable rest consists of a base, u, which is provided with slottedl feet u u. t is the guide, with knife-edge, this guide being connected or hinged to the base u by means of the arms ww, also pivoted to the guide, the same being adjustable, and the Whole being held in any required position by means of the circular slotted hinged'strap x.

When the rest is used the material to be planed is fed by hand, and the same readily finished, .leaving it perfectly straight, smooth, and. out of wind.

Thus, with our improved device, we are en-l abled to furnish a planing-machine that can be adapted to various purposes, and the depth and the portable adjustal two platforms a b applied to the specified.
