BAND-SAW MILL.

SPECIFICATION forming part of Letters Patent No. 348,280, dated August 31, 1886.

Application filed March 25, 1866. Serial No. 196,450. (No model.)

To all whom, it may concern: K, as clearly shown in Figs. 2 and 3, all the Be it known that I, GEORGE M. HINKLEY, wheels I J K being rigidly keyed to the shaft. of Milwaukee, in the county of Milwaukee L indicates a shaft extending at an angle and State of \Visconsin, have invented certain across the front side of the machine, carrying new and useful Improvements in Band-Saw at one end a bevel friction-wheel, M, and at 55 Mills, of which the following is aspecification. its other end a small bevel gear-wheel, N, My invention relates to band-saw mills; and which latter is adapted to mesh with a larger it consists, first, in a novel construction of bevel-gear, O, on the shaft G, as shown in mechanism for imparting motion to the saw Figs. 2 and 3.

The bridge P is provided in end elevation; Fig. 2, a top plan view of with a box or bearing, 1', in which is mounted themachine; Fig. 8, ahorizontalsection showa cylindrical block, j, shown in Figs. 4, 5, and ing the mechanism for driving the saw and the 6, said block j being provided with bearings carriage; Figs. 4, 5, 6, and 7, detail views 1e it, for the shaft L, eccentric to the block j. 70 lating to the driving mechanism; Figs. 8, 9, The block j is further provided on its front and 10, views illustrating the mechanism by face with a socket, Z, for the reception of a which the upper saw-guide is raised and lowhand-lever, m, by which the block j may be ered; Figs. 11, 12, and 13, views illustrating turned or rotated in its bearing i, to bring the 2 5 the construction of the upper guide. bearing is to one or the other side of the center 7 5 Referring now to Figs. 1, 2, and 3, the mechof the block j. anism by which motion is imparted to the saw The device being thus constructed operates and to the traveling carriage will be explained. as follows: Motion being imparted to shaft H In mills of this character the carriage must through band-wheel I is of course transmithave reciprocating movement past the saw, ted to the saw through the lower saw-support- 80 and to accomplish this by means of the power ing wheel, Q.

T indicates a rod connected to the screw 8 by means of a universal joint, t, the rod T being provided at its lower end with a bevel frictionwheel, U, as shown in Fig. 9, and supported at a point above the friction-wheel U by a bridgetrce, a. The bridgetree u is pivoted at its rear end to a lug projecting from the rear of the upright column R, and extends through said column to the front face thereof. As indicated by dotted lines in Fig. 1, the rod T also extends through the front face of the upright column B, and terminates directly over the shaft H. As shown in Figs. 3 and 8, the shaft H is provided with fixed bevel friction-wheels V and NV, between which the friction-wheel U hangs, the latter being arranged to hang freely between and out of contact with both of said wheels or to move in contact with either at will. Of course, if the wheel U should run in. contact with wheel V, it would turn, the screw sin one direction and cause a movement of the guide-arm; but if the wheel U should move in contact with the wheel W it would cause a reverse movement of the screw and guide-arm. The direction of rotation of the shaft H and the threading of screw 5 will of course determine which of the wheels 'V WV will be used to raise and which to lower the guide arm. As previously stated, and as clearly shown in Fig. 10, the bridge-tree a, supporting the shaft T, projects through the front side of the upright column B, where it is connected to a hand-lever, X, by means of a link, 1;, the hand -lever being pivoted at a point above the link to a bracket or support, 10, rigidly secured to the standard R. It will be seen that as the hand-lever is rocked on its pivot it moves the bridge-tree u, and the shaft T, carried thereby,in the direction of the length of shaft H, and will cause the friction-wheel U to come into contact with wheels V or XV, according to the direction in which the handlever is moved. A spring-dog, 00, secured to the bracket 10, engages with the end of the hand-lever X, and holds said lever normally in avertical position, thus rendering the wheel U inoperative.

Fig. 1 is a side or end view of my improved guide; Fig. 12, a face View partly in section; and Fig. 13, atop plan view. The end of the guide-arm S is provided with a slot'or groove, 1), extending horizontally across its face, as shown in Fig. 12, the groove being fitted to receive aweb or rib, 0, formed upon the rear face of a plate, A, secured to the guide-arm S by means of a bolt, y, from which it will be seen that the entire guide Y may be moved laterall y across the end of the guide-arm. The bolt 3 is provided with an enlarged head, as shown in Fig. 13, and projects through a slot. Shown in dotted lines in Fig. 12 in the guide-arm.) The plate A is provided with a laterally-extending arm, (1, and with a horizontal plate, 6, the former having at its end a bolt, f, and the latter having a bolt, 9. The horizontal plate 6 is countersunk or recessed on its under face around the bolt 9, to form a circular socket, h, to receive a hub or boss, '5, formed upon the upper face of a plate, j, secured to the plate 0 by means of the bolt 9. This plate j is formed with a laterally-extending arm, corresponding to and beneath the arm d of plate A, and said arm 7c is formed with a curved slot, Z, through which and the arm d the boltf passes, as shown in Figs. 11, 12, and 13. The sides or edges j are -beveled,as shown in Fig. 12, and slide in guides or ways formed upon the main portion of the guide.

Projecting from the guide Y, beneath the arm S, is a lug, m, in which is swiveled the shank of a screw, 12, provided with a handwheel, B, at one end,and screwing at the other end into a lug, 0, formed upon the underside of the plate j, as shown in Figs. 11 and 13 and by dotted lines in Fig. 12. From this construction it will be seen that by turning the hand-wheel B in one or the other direction the guides on the inner face of the saw maybe moved to and from the latter, as desired. The outer portion of the guide Y is formed of two sections, Z and 2, as shown in Fig. 12, the upper section, Z, being formed with a downwardly-projecting ear orlug, p,through which passes a screw, q, having at one end a handwheel, 0,,by which it may be turned. The upper section, Z, is dovetailed into the lower section, .2, as shown in Fig. 11, and is adjustable longitudinally npon the latter by means of the screw g, which screws into a lug, r, on the section 2, as shown in dotted lines in Fig. 12. This adjustment enables the lower section, 2:, of the guide, or the block a, carried thereby, to be moved closer to or farther from the rear edge of the saw, and also to compensate for wear of the block. Now, should it be found that the guidingblocks a were not parallel with the face of the saw, they could not be made so by the adjustment of either of the screws n q, as both of said screws move the guide-sections in fixed predetermined right lines. To accomplish or secure this parallelism it is only necessary to loosen the bolts f g and turn the platej upon the boltg as a pivot until the guiding-blocks are parallel with the face of the saw, whereupon the bolts f 9 may be tightened and the plate held in position. The upper arm, Z, extends outward beyond the lower arm, 2, and supports the saw near the cutting-edge, while the lower arm, 2, supports the inner face or side walls of the saw. Each of the arms Z and z is provided with a tapering dovetailed socket, in which is driven,

a block, a, of wood, preferably lignum-vitzc. As these blocks a are beveled on their edges and taper lengthwise, they ean be fitted quite easily with a plane and driven tightly to their seat. IVhen once driven, they need no fastening screws or bolts or other securing devices.

In using the term gear I do not wish to be understood as limiting myself to the use of toothed or friction gear, as it is obvious that either these or other forms of gearing may be used with equal advantage.

I do not in this application claim the construction of the upper saw-supporti n g wheel, as this feature will form the subiectmatterof a sepa rate application, to be filed asa division of the present case.
