HANDHOLD-SAWING MACHINE.
SPECIFICATION forming part of Letters Patent No. 784,348, dated March '7, 1905.
Application filed August 18, 1904. Serial No. 221,221.
To all whom, it may concern.-
Be it known that I, BERTRAM Josnrn PYE, a citizen of the United States, and a resident of Astoria, in the county of Clatsop and State of Oregon. have invented a new and Improved lrIandhold-Sawing Machine, of which the following is a full, clear, and exact description.
The invention relates to woodworking machinery; and its object is to provide a new and improved handhold-sawing machine designed for quickly and accurately forming handholds or grooves in end boards for boxes or the like to permit of conveniently handling the box.
The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.
A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
Figure 1 is a plan view of the improvement, part of the saw-table being broken out and a portion of the saw-stand being shown in section. Fig. 2 is a sectional side elevation of the same on the line 2 2 of Fig. 1. Fig. 3 is a rear end elevation of the same. Fig. 4 is an enlarged sectional side elevation of the feed mechanism. Fig. 5 is a rearend elevation of the same. 6 is an enlarged rear side elevation of the holding-down device for the work. Fig. 7 is a front end elevation of the same, and Fig. 8 is an enlarged sectional side elevation of a board formed with the handhold by the circular saw.
On the rear end of a suitable stand A is hinged at A (see Fig. 2) a table A resting at its forward end on set-screws A vertically adjustable on the stand A to allow of swinging the table A up or down, and with it the work B, resting on the said table, to bring the work in proper relative position to the revoluble cutting-tool O, employed for forming a groove or handhold B in the under side of the work, as indicated in Fig. 8, the depth of the groove or handhold B being regulated by adjusting the front end of the table up or down by the said set-screws A that is, by swinging the front end of the table upward the groove or handhold B cut is of lessdepth than the distance the front end of the table is allowed to swing downward.
The cutting-tool C is preferably in the form of a plurality of circular saws titted side by side and aggregating in thickness a distance corresponding to the width of the groove or handhold B to be made. An arbor (I, carrying the cutting-tool C. is journaled in suitable bearings I), mounted to slide up and down in vertically-disposed guideways A". formed on the stand A, and the said arbor O is engaged by eyes E, ad justabl y engaged by rods or arms E. fastened in position after the desired adjustment is made by nuts E as plainly shown in Fig. 3. The rods or arms F/ are provided with enlarged circular bearing portions E, mounted to slide up and down in suitable bearingsA forming part of the stand A, and in the lower ends of the bearing portions E are journaled friction-rollers E in engagement with the peripheral surfaces of cams F, secured on a transversely-extendingcam-shaft F, journaled in suitable bearings in the stand A.' On the cam-shaft F is secured a gearwheel F in mesh with a pinion F attached to a shaft F, likewise journaled in the stand A,
and provided with a pulley F", connected by belt with other machinery for imparting a rotary motion to the said shaft I. The rotary motion given to the shaft F is transmitted by the pinion F and gear-wheel F to the cam-shaft F. which by the cams F imparts an intermittent up and down sliding motion to the rods or arms E and their eyes E to move the arbor O bodily in an up and down direction and with it the cutting-tool (J. The latter is continually rotated independent,
however, of the cam-shaft F, and for this purpose the arbor O is provided with a pulley O over which passes a belt C, connected with suitable machinery for imparting a rotary motion to the said arbor C and the cuttingtool C. A tightening-pulley 0* engages one run of the belt C and this tightening-pulley C is preferably journaled on an arm O fulcrumed on the front end of the table A (See Figs. 1 and 2.)
The cutting-tool 0 when in a lowermost position is below the top surface of the table A and when the cutting-tool is raised its top is carried a distance above the top surface of the table A to cut into the workB the desired depth to form the groove or handhold B, as indicated in Fig. 8. The cutting-tool Cpasses through a suitable slot A, formed in the table A The boards Bto be successively provided with grooves or handholds B are arranged in a stack set on the top of the table A and abutting at one side against a gage G, adjustably secured by bolts G in transverse grooves A and A formed in the top of the table A. The rear sides of the stack of boards abut against acorresponding gage Lad justabl y fastened by a bolt I in the groove A and the forward ends of the stack of boards abut against a stop-gage H, held longitudinally adjustable on the gage Gr by bolts H, passing through elongated slots H (see dotted lines, Fig. 2) on the stop-gage H. The lowermost board B in the stack is pushed out from under the superimposed, boards so as to bring the bottom board in proper position above the tool C at the time the latter is in a lowermost position. and for this purpose a feed mechanism J is provided, arranged as follows, special reference being had to Figs. 2, 3, 4. and 5: The feedmechanism J is provided with a cross-head J, mounted to slide in a suitable guideway A", formed on' the table A and in the said cross-head J (see Figs. 4 and 5) is formed a T-slot J 2 for adjustably securing a block J by means of a bolt J to the cross-head J. On the block J is fulcrumed a pawl J pressed upwardly by a spring J ,attached to the block J the up wardswinging motion of the pawl J beinglimited by a projection J integral with the top of the block J. The free end of the pawl J 5 is adapted to engage the under side or the rear end of the lowermost board B at the time the cross-head J is in a rearmost position, so that when the cross-head is caused to slide forwardly the pawl J pushes the bottom board from under the stack and onto the forward end of the table A into proper relation to the cutting-tool O for the latter to cut the handheld or groove B as soon as the cutting-tool is caused to rise by the action of the cams F, as previously explained.
The cross-head J of the feed mechanism is provided with a depending lug J, connected by a link K with a rocking arm K, fulcrumed at its lower end at K on the stand A. The rocking arm K is connected by a pitman K with a crank-arm K*, secured on the cam-shaft F, so that when the latter is rotated the crankarm K and pitman K impart a swinging motion to the arm K, which by the link K reciprocates the cross-head J to move the same forward and backward in the guideway A for the pawl J to push the lowermost board in the stack out from under the stack and into position on the front end of the table A for the cutting-tool C to form the handhold.
During the time this takes place the crosshead J returns to a rearmost position. In order to give the desired resistance to the board to be formed with the handhold at the time, it is necessary to provide a holding-down device L, (shown in detail in Figs. 6 and 7,) provided with a bracket L, on which are held vertically-adjustable bearings L and L by bolts L L passing through elongated slots in the bearings and screwing in the bracket L In the bearing L is journaled a roller N and in the bearing L is eccentrically journaled a roller N, provided on its peripheral face and near the bottom thereof with a row of pins N to prevent return movement of the board when the cutting-tool C cuts the groove B. The roller N is normally held in position by a spring N, secured to the bearing L by the head of the bolt L as plainly indicated in Fig. 6. The smooth roller N is somewhat to the left of the top of the cutting-tool C, while the roller N is to the right of the top, and as the cutting-tool C rotates in the direction of the arrow at and the board B is pushed inwardly in the direction of theiarrow b and under the rollers N and N it is evident that the rollers N and N prevent upward movement of the board,and the eccentrically-mount ed roller N in addition prevents rearward movement of the board by the roller N tightening onto the top of the board owing to its eccentricity and also by its pins N embedding themselves in the top of the board. It is understood that the tendency of the saw C, rotating in the direction of the arrow at, is to push the board B in the inverse direction of the arrow 6, (see Fig. 8,) and hence the roller N by being eccentrically mounted is drawn tightly in contact with the top of the board on the slightest tendency to rearward movement of the board. By having the spring N the roller N is held normally in such position that the board can be readily moved forward under the rollers N and N by the action of the feed mechanism, as previously explained.
The bracket L is secured to the top of the table A and under the upwardly-extending arm of the bracket extends a gage P, adjustably secured by bolts P in T-slots A in the table A, the inner face of the gage P being in .alinement with the inner face of the gage Gr, as plainly shown in Fig. 1.
The operation is as follows: The gages Ur, H, and l are adjusted on the table A according to the size of the boards under treatment, and the boards are placed on the table in a stack, so as to fit the said gages, as previously explained. When the machine is set in motion by rotating the arbor G and the shaft F as previously explained, then the feed mechanism pushes the lowermost board. out from under the stack and onto the forward end of the table under the rollers N and N and above the cutting-tool C, the latter at this time being in a lowermost position. As soon IIS as the board is in position as described then the action of the cams F and connected parts, as previously explained, so that the cuttingtool cuts the groove or handhold in the under surface of the board. (See Fig. 8.) By ref erenceto Fig. 2 it will be seen that the cams F are so arranged that the saw during onehalf revolution of the cam-shaft F is in an uppermost position and then immediately drops into a lowermost position for the top of the cutting-tool to pass below the top of the feed-table A During the time the cuttingtool G is in an uppermost position the feedmechanism returns to a rearmost position to engage the now lowermost board and to push the same forward for this lowermost board to push the finished board off the table A and .to pass itself into position for receiving the groove or handhold B on the next rising of the cutting-tool (1.
From the foregoing it will be seen that the sawing-machine is completely automatic in operation, requires very little, if any, attention on the port of the operator, and a large number of boards can be provided with handholds in a comparatively short time. i
The sawing-machine is constructed in a very simple manner with a view to preventing the parts from easily getting out of order.
Having-thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A handhold -sawing machine provided with a revoluble cutting-tool, and a holdingdown device for the work, arranged opposite the said cutting-tool, the said holding-down device comprising two spaced rollers, one of the rollers being eccentrically journaled.
