WILLIAM H. GRAY, OF BROOKLYN, NEW YORK, ASSIGNOR TO THE GLEN COVE MACHINE COMPANY, (LIMITED,) OF SAME PLACE.

PRESSER-BAR FOR WOOD PLANING OR MOLDING MACHINES.

SPECIFICATION forming part of Letters Patent No. 361,506, dated Aprill9, 1887.

Application filed February 11, 1887. Serial No. 227,262. (No model.)

' has been commonly hinged at one side of the machine, and at the opposite side thereof has been inserted in a loop or shackle or otherwise held in place, so as to provide for its adjustrnent upward and downward.

In carrying out my invention I hinge the abovedescribed cross-bar at one end, as has been before done; but I provide anovel means of securing the bar at its free end, which enables the bar to be adjusted accurately upward and downward, and which also provides for expeditiously freeing the end of the bar from the means which hold it, in order to swingthe bar upward away from the cutter-head; and the invention which relates to such means for holding and adjusting the free end of the bar consists in novel combinations of parts and features of construction, hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation in a plane transverse to the length of the machine, showing the parts which are necessary to illustrate my invention, thecutter-head and the side frames and bearings being shown in dotted outline. Fig. 2 is a plan of the parts shown in Fig. l by full lines. Fig. 3 is an end view of the parts shown in Fig. 1, looking from the right hand of said figure; and Fig. 4 is a horizontal section upon about the plane indicated by the dotted line :0 m, Fig. 3.

Similar letters of reference designate corresponding parts in all the figures. 4

A designates the lower cutter-head, A the cutter-head boxes, and A portions of the side frames of the machine, all of which parts are shown in Fig. l by dotted lines, as they donot directly concern my invention- B is a cross-bar, which is usually arranged above the lower cutter-head and transversely of the machinein awood-planing machine, and upon this bar is a presser, which, as here shown, consists of a stock-piece, C, secured to the bar B, and an adjustable foot piece or presser, C, which may, by means of a screw, 0, be adjusted upward and downward relatively to the stock-piece C and the supportingbar B. The bar B is usually hinged at one side of the machine, and its free end is connected with means at the opposite side of the machine whereby the bar may be adjusted upward and downward and held securely in po sition after such adjustment. the bar I have represented a bracket, D,whioh may be bolted to one of the side frames of the machine, and to which the upright link or post E is hinged or pivoted at e,and at the other or free end of the bar is a bracket, D, from which rises a round post or column, E. The end of the bar B may be pivoted or hinged at e to the upright link or connection E, and the slot 6 in the link or connection E provides for adjusting that end ofthe bar upward and downward to suit considerable variations in height.

The means for securing the free end ofthe bar in place, and foradjusting it upward and downward, consist of a head, F, upon the post or column E, a collar or slide, F, which is fitted to both slide and turn upon the post E, and a screw, F which has its bearing f in the head F and which is threaded to engage a nut formed ILtlle collar F. The collar F has on one side a flattened surface, f, on which the free end of the bar B is secured by means of aclampingscrew, f and the free end of the bar may have in it a slot, b, as shown by dotted lines in Fig. 1, through which the clampingscrew f passes. WVhen the clamping-screwf is tightened, the end of the bar B is held securely against the flattened surface f of the collar F; but it will be observed that the slot 2) provides for turning the collar upon the post E whenever the clamping screw f is loosened, in order to remove the clamping-screw entirely from the bar B and permitsaid bar to be swung upward. The adjustment of the bar upward and downward is provided for by turning the screw F". After the free end of the bar At one end of cured by turning the screw F, and the bar between its periods of adjustment is held with sufficient firmness and rigidity to'euable the presser O to properly perform its work.

The head F and the collar F are both fitted to turn freely on the post E, and whenever the bar B is freed from the clamping-screw f or whenever said screw is slightly released, the head F, the collar F, and the screw F may be turned on the post E as one piece,to disengage and leave free the end of the bar B.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with the lower cutterhead and side frames of a planing or molding machine, of a bar carrying a presser extending across the machine and hingedlat one end on one side of the machine, a post at the other side of the machine, a slide movable vertically on the post and to which the end of the bar may be secured, and a screw,substantially parallel with the post, by which the slide may be raised and lowered, substantially as herein de scribed.

2. The combination, with the bar B, hinged atone end and carrying a presser and slotted at the other end, of the post E, the head F, and the collar F, both fitted to turn on the post and the collar being provided with a fiat face, f, and a clamping-screw, f, forsecnring the bar, and the adj usting-screw F connecting the said head and collar and serving to adjust the collar vertically on the post, substantially 35 as herein described.
