HORIZONTAL BAND-SAW.
SPECIFICATION forming part of Letters Patent No. 748,025, dated December 29, 1903.
Application filed February 5, 1903. Serial No. 142,028. (No model.)
To atl whom t may concern:
Be it known that I, CHARLESC. STUART, a citizen of the United States, residing at Campville, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Horizontal Band- Saws, of which the following is a specification.
This invention relates to horizontal bandsaws, and especially to improvements on the machine for which I filed an application, Serial No. 140,186, January 22, 1903. The invention referred to has a single horizontal endless table sectionally jointed, while this has two tables of the same description, fed by the same means as heretofore, placed side by side, with a modification whereby the tables maybe run in opposite directions against a saw with teeth on each edge, so that stock may be sawed on eachtable at the same time. The tables are carried in one frame, the same as heretofore for the single table, and are elevated and fed by the same means as hereto-i fore, while one of the tables is'provided with additional means whereby itis independently raised above the other table. The object in raising the tables at different elevations is to saw stock to a dierent thickness on each table, and by running the tables in opposite directions the stock can be passed back and forth and sawed Without loss of time, while giving ample time to shift the stock from one table to the other as they are run at different speeds.
This invention is illustrated by the accompanying'drawings, in which similar characters of reference indicate similar parts, and in which- Figure 1 is an end elevation showing the tables in different elevations. Fig. 2 is a section on line .fr Fig. 3, showing the add-` tional elevating means for one table. Fig. 3 is a plan or top view of the frame and tables with some parts in section. Fig. 4. shows in section the same table as Fig. 2 when elevated by the additional m'eans.-4 Fig. 5 shows Fig. 6 is a section on line B,
'Figs.f4,5, showing the gearing to run the tables in opposite directions. Fig. 7 is one half a cross-section on line A, Figs. 2, 4, showing the additional elevating means, and one half an end view of the main frame andthe fixed table-frame in section on line C, Figs. 2, 4, showing the means to adjust and support t-he table-frames on the main frame. Fig. 8 is a side view of the table-frame, some parts being in' section, showing the means for elevating the table. Fig. 9 is an end view of as much as is necessary to show their connection.
As in the previous application, the machine is provided with the same bed-plate, driving and driven wheels and means for adjustment, feedworks, and the main frame, with its means for' elevation. In `this inventionthe main frame 1 supports two tableframes 2 3. Table-frame 2 is a fixture with the main frame, as its movement toward or from the saw is controlled by the main frame, on which it rests in a fixed position on adjusting-screws 4 (see Fig. 7) in the main frame, the screws being employed to overcome any inaccuracy of construction. On table-frame 2 the sectionally-jointed and endless table 5 is secured and moved across the path of the saw continuously. Table-frame 3 is placed in main frame 1 parallel with table-frame 2 and is carried up and down with main frame 1 and table-frame 2; but for the purpose set forth it is provided with additional means for its e1evation,which is entirely independent of the main frames means for elevation. Upon the table-frame 3 is placed the sectionallyjointed and endless table 6 for continuous movement across the path of the saw. Tables 5 6 are of the same construction as fully set forth for the single table in my previous applicatiom The. table-frame 3 has pairs of arms 7 8 supported at one end on shafts 9 10, which carry the main frame 1. At their opposite end arms 7 8 are joined to pairs of bell-cranks n11 12 by shafts 13 14., journaled in the table 3 at their outer ends and havingin one arm of each crank adjusting-screws 15, which rest upon main frame 1. At, their opposite ends they are connected by shafts 16 17 to V- shaped clevises 18 19, the clevises being connected at their center by a rod 20, which has posite end, is screw-threaded, and has a nut bed-plate.
23 and check-nut 24. A rod 25, Withits head 26 inside of the clevis 19, passes outward through a slotted hole 27 in main frame 1, Where it is screw-threaded and provided with a washer 28 and a Spanner-nut 29.
To independently elevate table-frame 3 and its endless table 6, it is only necessary to turn nut 29, when shafts 13 14 will be moved upward, as seen in Fig. 4, carrying up frame 3 and table 6. The centers of shafts 9 13 and shafts 30 3l are the same, so that gear 32 will at any point of elevation be in correct contact with pinion 33, the frame and table being radially elevated. The endless tables 5 6 run in the same direction when their racks 34 are engaged by the intermediate 32, driven hy pinion 33, which is the case at all times for the independently-elevated frame 3 and its endless table 6. When it is necessary or desirable to run the tables in opposite directions for the purpose of using a saW 35 with double cutting edges, as seen in Fig. 3, the pinion 33 andintermediate 32 Will be replaced by a gear 36 on shaft 31, as seen in Fig. 5,
which directly engages rack 34 and runs the table 5 in an opposite direction to that of table 6 and at greater speed, so that stock placed on table 5 at its end D Will when it reaches its opposite end give the attendant ample time to'shift it to the slower-moving table 6.
Bed-plate 37 and supplemental bed-plate 38 support columns 39, around which are sleeves 40, having arms 41, which reach out- Ward and upward and carry shafts 9 10, which support the main table 1. Within the sleeves at their top are attached nuts 42, screwth'read-ed to receive the elevating-screws 43,
`which have collars 44 seated on sleeves 45,
carried on the bed-plate and supplemental At their lower end the screws pass through the sleeves and have attached th'ereto'bevel-gears 47 48, Which engage pinions 49 on shaft 50, which Work the gears and screws in unison. The shaft is supported in bearings 51, pendent from a plate 52, supported by the bed-plate 37 and supplemental bed-plate 38. Attached to gear 47 isa spur- I claim- 1. In a horizontal band-saw a frame, supported for elevation toward or depression from the saw to thereby gage the thickness of material cut, and independent frames mounted therein and carrying sectionallyjointed endless tables moving across the path of the saw.
2. In a horizontal band-saw,xneansto mount and move the saw, a main frame supported for elevation and depression relative toits distance from the saw, independent frames mounted on the frame aforesaid, one of said frames being fixed, to rise and fall with the main frame, and one being fixed to move vertically with the main frame, and also independently of the main frame, means for such independent movement, and a sectionallyjointed endless table supported upon each independent frame, and means for their movement in the same direction across the path of the saw.
3. Inahorizontalbandsaw,means to mount and move the saw, `a main frame supported for elevation and depression relative to its distance from the saw, independent frames mounted on the frame aforesaid, one of said frames being fixed, to rise and fall With the main frame, and one being xed to move vertically with the main frame, and also independently of the main frame, means for such independent movement, and a sectionallyjointed endless table supported upon each independent frame,and means for their movement in opposite directions across the path of the saw.
4. In a horizontal band-saw, means to mount and move the saw, a main frame supported vfor elevation and depression relative to its distance from the saw, independent frames mounted on the frame aforesaid, one of said frames being fixed, to rise and fall with the main frame, and one being fixed to move ver-v tically with the main frame, and also independently of the main frame, means for such independent movement, and a sectionallyjointed endless table supported upon each independentframe,and means for their movement in opposite directions, and at different speeds across the path of the saw.
