SAW-TABLE.
SPECIFICATION forming part of Letters Patent N 0. 744,190, dated November 17, 1903.
Application filed August 14, 1902. Serial No. 119,681. (No model.)
To all whom it may concern.-
Be it known that I, EDWIN T. GORHAM, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented new and useful Improvements in Saw-Tables, of which the following is a specification.
This invention relates to certain new and useful improvements in saw-tables, and more especially to saw-tables which are tilted in order to cut the stock at any required angle.
The invention consists in the construction and combination of parts hereinafter described and claimed.
The objects of the invention are, first, to construct a saw-table having its saws supported by a yoke and mechanism whereby the yoke may be so securely and rigidly supported as to obviate vibration; second, to provide a tilting saw-table that can be adjusted with great accuracy and precision; third, to furnish means whereby a large saw can be applied to the saw-arbor; fourth, to furnish efficient and accurate meansfor tilting'and adjusting the table-top; fifth, to provide means for retaining an even and efficient pressure upon the belt which runs the saws; sixth, other objects hereinafter pointed out and claimed. These objects I accomplish by means of the mechanism illustrated in the accompanying drawings, in which- Figure 1 shows an end elevation, partially in section, of a saw-table constructed in accordance with myinvention. Fig. 2 showsa sectional view on line X X of Fig. 1. Fig. 3 shows the side elevation of the table tilted and a portion of the machine cut away in order to more clearly illustrate the table-tilting mechanism. Fig. 4 shows a detailed view of the retaining-cap B, which engages with the journal of the oscillating yoke, which yoke supports the saws. Fig. 5 is a sectional view illustrating the supporting-frame of the saw-table. Fig. 6 is an enlarged detail view showing-in solid lines the bearing-pin forming a support for the yoke and showing by' dotted lines the bearing-pin drawn out.
Similar letters refer to similar parts throughout the several views. I
A'represents the arbor-yoke, which carries the two saws and which is adapted to bring either saw into position for use by means of the mechanism hereinafter described. (See Figs. 1 and 2.) a
A is whatI call the yoke-journal, which is an enlarged journal and is supported in the main frame of the machine and securely retained in position, so as to prevent any oscillation of the yoke. This journal is provided with a screw-thread, with which engages the screw-threaded cap B. The cap B is screwed upon the end of thejournal A until it comesin contact with the smooth outer surface of the main frame of the machine. The position of the ,cap is shown bythe sectional view in Fig. 2 and is also illustrated in a detailed view'in Fig. 4.
Referring now to Fig. 4, e is a slot in the cap B... The cap B is provided with projecting lugs 12 b, and a bolt B passes through these lugs and engages with the nut c. When the cap B has been applied to the end of the journal until the same bears against the frame, as above described, the bolt B is tightened, so as to clamp the cap B firmly upon the thread of the journal and to retain the same securely and rigidly thereon, thus holding the yoke A rigidly and securely in a horizontal position and preventing vibration of the said oke.
y D is a Worm-wheel rigid with the arbor-yoke journal and may be made integral therewith.
C is a worm which engages with the wormwheel D. This is shown in Fig. 2. Ahandwheel 0 operates the worm 0, thereby shifting the arbor-yoke so as to bring either saw into position to operate upon the stock, the stock being placed upon the table and the saw to be used being raised so as to project above the table.
E represents the saw-arbor for the saw K, and E represents the arbor for the saw K. Thesaws may be of different kindsthat is, one of the saws may be an ordinary cut-off saw and the other may be a rip-saw. These saws may be readily removed from their arbors and a single large saw applied to one of the arbors, if desired, as hereinafter described. The table-top is constructed in two tension F, as shown in Figs. 2 and 3. This part F may be detached, if required.
I represents the movable part of the tabletop, which is supported by the adjustable- 5 frame Q, hereinafter described, Q being a portion of the tilting-frame which supports the table-top. It provides for longitudinal movement of the movable section of the table. For this purpose I provide an antifrictionro roller, (shown byJ in Fig. 2.) The adjustable frame Q, may be adjusted toward and from the saw, so as to increase or decrease the opening through which the saw passes.
In order to give greater steadiness to the arbor-yoke, I have provided a removable steadying pin or bearing L, which passes through an opening in the main frame of the machine and into a central opening in the center of the yoke A, thus forming a second journal-bearing for the said yoke. I also provide a boss M on the frame, through which the steadying-pin L passes. This gives it greater stability. If at any time it becomes desirable to use a single large saw, the pin L can be removed and one large saw applied to the self-supporting yoke.
Each saw is provided with a band-pulley, which are shown by G and G. The band which operates these pulleys is shown in Fig.
shown by the band-wheel 2 in Fig. 1. 'In order to retain the band 3 in condition to operate the band-pulleys G and G, I provide two idlers, which are supported by the idler-yoke O, which yoke is pivoted at 7 and carries the 40 two idlers N and N.
Referring to the connection with the bandwheel 1, as shown in Fig. 1, it will be noted that one idler rests upon the outside of the band 3 and that the other idler rests upon 5 the inside of said band 3. The band 3 supports the weight of the two idlers and the yoke O. This keeps the band 3 uniformly taut and insuresasteady and positive movement of the saws.
P is a partition between the saws and the operating mechanism, the object of the partition P being to exclude the sawdust from the working parts of the machine.
R represents a clamp for the adjustable frame Q. This clamp secures the adjustable frame Q to the stationary frame H of the table-top.
S represents a latch used for securing the sliding table in its stationary position. The
1 6o latch is pivoted at the point 8 and is provided with a projection 9, which fits into the notch in the lug 10, said lug being one of the bearings of the movable part of the table.
The table and table-frame are supported in the segment T, which segment T is supported by the bearing U, the segment T serving as a journal and being the part of a cirole the center of which is the center of the saw at the point where it passes through the table.
By this construction the table may be tilted without displacing the opening through which the saw passes and without interfering with the saw. The table, together with the supporting-frame,is tilted by means of the mechanism hereinafter described, in which (1 represents a worm-wheel supported in the frame and provided with cogs adapted to engage with the worm c. The worm-wheel d is provided with an arm rigidly connected therewith. (Shown in Fig. 3 by X.) Pivoted to the free end of the arm X is the connectingrod W, the upper end of which connectingrod is pivoted to the tilting table-frame, as shown in Fig. 3.
(1 shows a hand-wheel provided with a suitable handle for operating the worm c. turning the hand-wheel d the worm-wheel d is operated and the arm X is raised and lowered and likewise the table is tilted. Thus the table can be tilted and retained rigidly in any required position, and by means of the index-finger and dialV the angle to which the table is tilted will be accurately recorded and the stock may be cut at any required angle and with great accuracy.
As a matter of convenience I provide a shelf Y, which may be used for the purpose of holding tools which are convenient to use in connection with the machine.
While I have illustrated the band-wheel l as located above the floor upon which the sawtable is mounted, I do not desire to be limited to this precise location of the band-wheel or operating mechanism, as it will be obvious that the saws may be operated in many ways beside that which I have illustrated without departing from the spirit or scope of my invention.
Having thus described my invention, what I claim to have invented, and desire to secure by Letters Patent, is
l. In'combination with the main frame of a saw-table a saw-carrying yoke, an enlarged journal A and an adjustable cap B engaging with and retaining the journal in position.
2. In combination with the frame of a sawtable an enlarged journal A, an adjustable screw-cap B bearin g against the outer surface of the said table and suitable mechanism for locking the said cap 13 in position.
3. In combination with the frame of a sawtable of a yoke-carrying saw, a screw-threaded slotted cap bearing against the frame and suitable mechanism for clamping the cap upon the journal A of the said yoke, substantially as described.
4. In combination with the frame of a sawtable a yoke supporting the saws, a journal A havinga screw-thread, a cap engaging with the said screw-thread, suitable means for securing the said cap rigidly in position, a wormwheel rigidwith the said journal A, a worm engaging with the said worm-wheel, and suitrotatable yoke adapted to support one or more revolving saws, and a removable hearing at I5 one end of said rotatable yoke, said bearing being removed when it is desired to use a saw of increased diameter.
In testimony whereof I have hereunto set my hand in presence of two subscribing wit- 2o nesses.
