CHARLES W. BORG, 0F MOLINE, ILLINOIS.

WOOD-PLANING- MACHINE.

Specification of Letters Patent.

Patented Sept. 9, 1913.

Original application filed September 7, 1906, Serial No. 333,707. Divided and this application led January 23, 1907.

To all wh-0m it may concern Be it known that I, CHARLES IV. BORG, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in YWood-Planing Machines, of which the following is a specilicaticn, reference being had therein to the accompanying drawing.

This case is a division of my prior application, filed September 7, 1906, Serial Number 333,707 3 upon which was issued Patent No. 965,983, dated August 2, 1910. In this patent are fully described and claimed features not claimed in the present application.

The object of my invention is to provide in a single wood-planing machine, a standard joint-er and a standard straight work sticker, capable of chain or roll feed and a Wide range of adjustments for different lines of work.

In the drawings: Figure 1 is a front elevation of my machine; showing also parts described and claimed in the application above named; Fig. 2 is a plan view of the same; Fig. 3 is a perspective detail of the feedroll drive; Fig. ,et is a detail, partially in sect-ion, of the feed-table elevating mechanism and Fig. 5 is a det-ail of the feed-chain drive.

The numeral 1 represents the base of the machine frame, 2 the front side of the boX frame mounted on said base, 3 the rear side of said box frame, 4 and 5 the front and rear ends of said boX frame, 6 the vertically-adj ustable shaping-table which carries and controls a bottom jointing cutter, an outside shaping cutter and the associated side presser mechanism hereinafter more fully described. Said feed table is vertically adjustable by means of an elevating screw 7 attached thereto, as shown in Fig. 1 and projecting downwardly into a standard 8 integral with or attached to the base 1. Said screw is operated by means of a hand wheel 9 o-n a shaft 10, said shaft having at its inner end a bevel-gear 11 which meshes with a second bevel-gear 12, said gear 12 also constituting a nut for the elevating screw 7, as clearly shown in Fig. 1. Said table is suitably guided in ways on t-he side 2 of the boX frame and is clamped in its adjusted position by means of a clip 13 which contacts with a downwardly projecting support 14 suitably attached to the box frame, said Serial No. 353,663.

support 14 also providing at its upper end a bearing for the upper facing cutter hereinafter more fully described. Said table 6 supports at its forward or entering end a j ointer-table section 15 having downwardly projecting wedge sections 16, 16, as shown in dotted lines in Fig. 1, which wedges rest upon corresponding wedge sections 17, 17 formed at the bot-tom of a longitudinally arranged slot in the table 6, as will be understood from Fig. 1. The table section 15 is adjusted both vertically and longitudinally by means of a lhand wheel 18 carrying a screw 19 which passes through a threaded lugy 2O depending from the bottom of the table 15; and the table 15 when adjusted is clamped by means of screws 21, 21, in any desired relation with the bottom or jointing cutter hereinafter more fully described. That portion of the table 6 in rear of said jointing cutter, carries a friction reducing roll 22, adjustable with relation to said table, as will be understood from Fig. l. As shown at the right of Fig. 2 said table 6 has lattached thereto an adjustable side jointing section 23 for receiving the blank or workpiece after it has passed the side jointing cutter hereinafter described.

The bottom jointing cutter is shown as a whole at 24 and is adjustable with relation to table 6 by means of the slotted bearing 25, guides 26 and clamping nut 27 (Fig. 1). This cutter is driven by means of a pulley 28 receiving its power from a belt driven from themain counter-shaft (not shown) but attached to the floor of the shop at the right of Fig. 2 as will be readily understood.

29 indicates as a whole a top dressing cutter suitably mounted in boxes or journals 30 on the top of t-he main frame, as clearly shown in F ig. 2. This cutter receives power from the main counter-shaft by means of a belt passing over the pulley 31, as will be readily understood. The side jointing cutter 32 is mounted on a vvertical shaft 33 and receives its power from the'main countershaft through a belt passing over the pulley 34 with a quarter turn, as will be apparent from Fig. 2. Said jointing cutter is laterally adjustable in guides 35 secured to the main frame; being carried in a journal frame 36 which may be adjusted and clamped by any desired mechanism (not shown).

The parts` 37 to 50e herein shown may be 98 to 104 (Fig. 5) and thecam 41, will remain at rest. The cut-ter 37 may then be adjusted by hand and remain stationary in any desired position, so as to operate as a jointing cutter, similarly to the cutter 32, already described. y

The gear train which drives the main feed shaft 81 is provided with a suitable shield 105 and the belt which actuates said feed train may be controlled by idlers 106, 106, mounted on a T-shaped lever or carrier 1,07, which carrier is pivoted on a stud 108 suitably mounted on the mainA frame. The third arm of the carrier 107, is connected by a link or rod 109 to a lever 110 pivoted as at 111 to the box side 3 of the main frame and extending upwardly within reach of the operator where it is provided with an operating handle 112 for controlling the belt tightening pulleys 106, as will'be'readily understood. This lever 110 and the link 109 are so mounted and proportioned that wher.= the aforesaid lever is swung to one side of its pivot its weight will tend to hold the tighteners .106 in contact with the driving bolt; and when swung t-o the opposite side it will tend to hold said tighteners out of contact with the driving belt and stop the entire feed train of the machine.

The work guiding means, as distinguished from the work propelling means, comprises the following: On the table 15 may be adjustably mounted a plurality of studs 113 carrying leaf springs 114. The studs 113 being vertically and rotatably adjustable in the table 15 and secured in any desired position by clamping screws 115. After the work-piece has passed the bottom jointing and top dressing cutters 24 and 29 and has been reduced to uniform depth and provided with smooth upper and lower surfaces, it may be further held to its path of movement by adjustable but rigid guides 116, 116, se cured to the main frame and vertically movable by means of the adjusting screws 117. The work-piece after having passed the cutters 37 and 32 (the former having in this event no lateral movement), the finished piece may then be held to the vertical face 23 by means of an adjustable guide 118.

Operation: For jointing or sticking straight work, it will be readily understood that the shaping cam 41 may be held stationary by disconnecting its drive at the clutch 97 (Fig. 5). The feed chain drive may be also disconnected by moving the bevel gear 91 out of contact with gear 92 and t-he feed teeth (or so many thereof as is necessary) Vmay be removed from the feed chain to leave clear the path of the blank which may then be driven solely by the toothed feed rolls 57; or, if preferred, both the rolls and feed chain may be used for feeding short pieces of straight work. The shaping cutter may remain in Contact with the outer side of the blank so as to merely dress it in straight lines, or may be thrown altogether out of contact with the outer edge of the work.

It is apparent that many changes may be made in the proportion and arrangement of parts of my machine without departing from my invention; since wWhat I claim is:

1. In a wood-working machine, the combination of an initial horizontal feed table, a cutter adapted to be adjusted to have its cutting plane above the said feed table, a horizontal plane table in the rear of the cutter, means for adjusting the cutter to have its cutting plane exactly in the plane of the said plane table or above said plane table as desired, a series of feed-rolls above said tables, some of the rolls of said series contacting with the blank before said blank reaches the cutter, others of the rolls of said series contacting with the blank after it has passed the cutter, mechanism which holds the first rolls of the series in contact with the blank with comparatively light pressure and which holds the other rolls of the series in contact with the blank with comparatively heavy pressure.
