Definitions
- This invention relates to sawing-machines; and the object thereof is to provide an improved machine of this class particularly adapted for use in sawing metal for various purposes, but which may be employed for sawing other substances; and with this and other objects in View the invention consists in a machine for the purpose specified constructed as hereinafter described and claimed.
- a suitable frame or support the various parts of which are designated by the reference-letter a, and said frame is provided with a bed plate or portion a and near the right-hand end thereof with an upright member a in which is mounted the main shaft 12.
- the machine is driven by a pulley 2, secured to the main shaft b and connected with a wheel or disk 2 by means of a starting-lever 3, which operates a clutch 4. (Shown in Fig. 3.)
- the wheel or disk 2 transmits, through the connecting-rod '5, eccentrically connected therewith, a reciprocating motion to the sawframe 6, which slides on guides 7, supported on an arm 8, said arm being mounted on the main shaft 19 or on eccentrics b, fixed to or connected with the said main shaft, the said eccentrics being provided in order to impart a rocking motion to the saw, thereby increasing its rate of cutting.
- this rock ing motion is obtained by setting the saw 6 at an angle with the guides 7, this construction being used either in conjunction with the eccentrics or otherwise.
- the arm 8 is capable of moving vertically on the shaft 1) or on the eccentrics, it being understood that the saw-frame 6, the saw 6, connected therewith, and the other parts connected with the said frame, as hereinafter described, rise and fall with the arm 8, to which they are connected, and this operation results in feeding the saw through the material to be sawed thereby, which material is held by the vise-jaws 9.
- the repetition mechanism comes into action, said repetition mechanism being constructed and operating as follows:
- a flat spring 10, Figs. 1 and 2 is attached to the saw-frame and engages with a catch 11, mounted longitudinally of the bed or frame of the machine, and during the forward stroke presses said catch forward and downward until it enters a hole 12 in the bed of the machine.
- the catch 11 is connected by a link or spring 13, Fig. 1, a lever 14:, Fig. 3, and a shaft 15, Fig. l, and a lever 16 to a clutch 17, (shown in Fig. 3,) which is in the form of a sprocket-wheel mounted on the main shaft.
- the sprocketwheel 17 is thereby caused to revolve, setting in motion a chain 18, mounted thereon and on a cam-wheel 19, mounted on a shaft 19 in the end of the machine opposite the main shaft Z) and below the bed of the machine, which cam-wheel makes one complete revo lution.
- the cam-wheel 19 is of the form of an ordinary sprocket-wheel and is operated by the chain 18, and said cam-wheel is provided with a cam 19 and a cam-flange 19.
- the cam-wheel 19 operates a lever 20, which is connected by a link 21 with the arm 8, and the said arm is thereby raised and raises with it the saw-frame 6 until the saw is quite clear of the work or the material on which it operates.
- the cam-wheel 19 then operates extractor 22, which is provided at its upper end with a nut 23 of one of the vise-jaws 9, and said parts are thereby drawn backwardly, releasing the metal or other material and allowing it to feed forward, as hereinafter described, until it meets with astop 23, mounted on a transverse shaft 39, previously set to regulate the amount of material to be cut off.
- the cam-Wheel continuously revolves and moves the vise-lever 22, so as to close the vise and grip the material to be sawed, and said cam-wheel moves the lever 20, so as to lower the saw onto the material, and finally the lug 24 on the cam-wheel 19 engages with a lever 25, mounted on the support of the lever 20,
- the manner of feeding the work forward is as follows:
- the chain 18 passes over a sprocket-wheel 26, mounted above the bed of the frame, and said chain is kept in engage ment with said sprocket-wheel by an idler 27, mounted thereover and at one side thereof, and said sprocket-wheel 26 or the shaft thereof is connected by a pair of beveled gears 28, as shown in Fig. 3, with the shaft of a feedroller 29, on which the material to be sawed rests, and said roller is thereby caused to revolve and to push the material forward against the stop 23, as already described.
- Fig. 4 In Fig. 4 are shown certain parts in detail.
- the material to be sawed is represented by the reference-letter w and rests on the feedroller 29 and is pressed into close contact therewith by a roller 30, carried on an arm 31, pivoted upon a fixed support 31 and actuated by a spring 31".
- a roller 30 carried on an arm 31, pivoted upon a fixed support 31 and actuated by a spring 31".
- the top roller 30 and the arm 31 fall, thereby causing the finger 32, connected with the arm 31 or forming part thereof, to engage with a bell-crank lever 33, (shown in Figs. 3 and 4,) which carries a striker 34 (see Fig.
- the catch 11 may be pushed to the left-hand side of the inclined piece 36, (shown in Fig. 4,) and in this case the spring 10 does not engage with said catch, but passes down beside it, and the saw-frame descends, as before described, until it engages with the curved piece 38 and rings the bell, as before.
- Fig. 5 shows the raising-lever 20 and the stop 23.
- the rod 39, on which the stop is mounted passes through a hole in the lever 40, which can be readily attached to it by means of a set-screw, and the lever 40 is connected by a link 41 with the raising-lever 20.
- the effect of this construction is that when the raising-lever 20 is raised by the camwheel 19, so as to raise the saw clear of the material, the stop 23 is caused to move to the left until it comes opposite the end of the material as it is fed forward.
- the stop 23 moves to the right until it is clear of the end of the material, thus preventing any possibility of the detached piece of the material jamming between the stop and the saw-blade and breaking thelatter.
- the pressure of the saw on the material is regulated by the weight 42, (shown in Figs. 1 and 2,) which is supported by a knife-edge device 44 from a rack 43, which may take the form of a screw for convenience in manufacture.
- a forked link 45 is freely pivoted about a point on the weight, as shown, and is provided with a knife-edge arm 46, which also rests on the rack, and the efiect of this arrangement is that as the inclination of the rack to the horizontal is changed by the raising of the saw the weight moves to the left one tooth of the rack.
- the link 45 advances one tooth.
- the weight advances one tooth after each piece of material is cut off and slowly increases the pressure on the saw, so as to compensate for the blunting of the latter through use.
- the falling of the saw-frame maybe checked by any suitable devices.
- a sawing-machine comprising a frame having a main shaft, and vise-jaws one of which is movable, a vertically-movable sawblade car ier mounted on said shaft, devices for feeding the material to be sawed transversely of the frame between the vise-jaws, a sprocket-wheel mounted on the main shaft, a cam sprocket-wheel mounted in the opposite end of the frame, means for gearing said sprocket-wheels in connection, and devices in operative connection with said cam-wheel for raising the saw-carrier, substantially as shown and described.

SAWING=MACHINE.
SPECIFICATION forming part of Letters Patent No. 691,139, dated January 14, 1902.
Application filed December 18 1900. Serial No. 40,234. (No model.)
T0 to whom it may concern:
Be it known that I, EDWARD GEISLER HER- BERT, a subject of the Queen of Great Britain, residing at Manchester, England, haveinvented certain new and useful Improvements in Sawing-Machines, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.
This invention relates to sawing-machines; and the object thereof is to provide an improved machine of this class particularly adapted for use in sawing metal for various purposes, but which may be employed for sawing other substances; and with this and other objects in View the invention consists in a machine for the purpose specified constructed as hereinafter described and claimed.
The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by the same reference characters in each of the views, and in which v Figure 1 is a side elevation of my improved sawing-machine; Fig. 2, an end elevation thereof, Fig. 3, a plan view; and Figs. 4 and 5, respectively, are views of details of the construction I employ.
In the practice of my invention I provide a suitable frame or support, the various parts of which are designated by the reference-letter a, and said frame is provided with a bed plate or portion a and near the right-hand end thereof with an upright member a in which is mounted the main shaft 12.
The machine is driven by a pulley 2, secured to the main shaft b and connected with a wheel or disk 2 by means of a starting-lever 3, which operates a clutch 4. (Shown in Fig. 3.) The wheel or disk 2 transmits, through the connecting-rod '5, eccentrically connected therewith, a reciprocating motion to the sawframe 6, which slides on guides 7, supported on an arm 8, said arm being mounted on the main shaft 19 or on eccentrics b, fixed to or connected with the said main shaft, the said eccentrics being provided in order to impart a rocking motion to the saw, thereby increasing its rate of cutting. Alternatively this rock ing motion is obtained by setting the saw 6 at an angle with the guides 7, this construction being used either in conjunction with the eccentrics or otherwise. The arm 8 is capable of moving vertically on the shaft 1) or on the eccentrics, it being understood that the saw-frame 6, the saw 6, connected therewith, and the other parts connected with the said frame, as hereinafter described, rise and fall with the arm 8, to which they are connected, and this operation results in feeding the saw through the material to be sawed thereby, which material is held by the vise-jaws 9. When the saw has cut through the material, the repetition mechanism comes into action, said repetition mechanism being constructed and operating as follows: A flat spring 10, Figs. 1 and 2, is attached to the saw-frame and engages with a catch 11, mounted longitudinally of the bed or frame of the machine, and during the forward stroke presses said catch forward and downward until it enters a hole 12 in the bed of the machine. The catch 11 is connected by a link or spring 13, Fig. 1, a lever 14:, Fig. 3, and a shaft 15, Fig. l, and a lever 16 to a clutch 17, (shown in Fig. 3,) which is in the form of a sprocket-wheel mounted on the main shaft. The sprocketwheel 17 is thereby caused to revolve, setting in motion a chain 18, mounted thereon and on a cam-wheel 19, mounted on a shaft 19 in the end of the machine opposite the main shaft Z) and below the bed of the machine, which cam-wheel makes one complete revo lution. The cam-wheel 19 is of the form of an ordinary sprocket-wheel and is operated by the chain 18, and said cam-wheel is provided with a cam 19 and a cam-flange 19. The cam-wheel 19 operates a lever 20, which is connected by a link 21 with the arm 8, and the said arm is thereby raised and raises with it the saw-frame 6 until the saw is quite clear of the work or the material on which it operates. The cam-wheel 19 then operates aviselever 22, which is provided at its upper end with a nut 23 of one of the vise-jaws 9, and said parts are thereby drawn backwardly, releasing the metal or other material and allowing it to feed forward, as hereinafter described, until it meets with astop 23, mounted on a transverse shaft 39, previously set to regulate the amount of material to be cut off.
The cam-Wheel continuously revolves and moves the vise-lever 22, so as to close the vise and grip the material to be sawed, and said cam-wheel moves the lever 20, so as to lower the saw onto the material, and finally the lug 24 on the cam-wheel 19 engages with a lever 25, mounted on the support of the lever 20,
which it draws back against the resistance ofa spring, and as the cam-wheel continues to revolve the lever is released and the end thereof enters the hole 12 in the bed of the machine from below and forces the catch 11 out of. the said hole, thereby releasing the clutch 17, to which the catch 11 is connected, as before described, the clutch 17 being provided with a spring which forces it open when the catch 11 is released from the hole 12. The cam 19 then remains stationary until the next piece of material is cut off, when the same process is repeated.
The manner of feeding the work forward is as follows: The chain 18 passes over a sprocket-wheel 26, mounted above the bed of the frame, and said chain is kept in engage ment with said sprocket-wheel by an idler 27, mounted thereover and at one side thereof, and said sprocket-wheel 26 or the shaft thereof is connected bya pair of beveled gears 28, as shown in Fig. 3, with the shaft of a feedroller 29, on which the material to be sawed rests, and said roller is thereby caused to revolve and to push the material forward against the stop 23, as already described.
In Fig. 4 are shown certain parts in detail. The material to be sawed is represented by the reference-letter w and rests on the feedroller 29 and is pressed into close contact therewith by a roller 30, carried on an arm 31, pivoted upon a fixed support 31 and actuated by a spring 31". When the whole of the material has been cut'up and no longer keeps the rollers 29 and 30 apart, the top roller 30 and the arm 31 fall, thereby causing the finger 32, connected with the arm 31 or forming part thereof, to engage with a bell-crank lever 33, (shown in Figs. 3 and 4,) which carries a striker 34 (see Fig. 1) in such manner that said striker is brought into engagement with the crank-pin as it revolves, thus causing the bell or gong 35 to ring. The curved portion of the bell-lever 33 passes under the catch 11, and an inclined portion 36 raises the said catch out of the hole 12 in the bed of the machine-frame and releases the clutch 17 and throws the repetition mechanism out of gear.
To recapitulate, when the material is cut up. the top roller 30 falls, throwing the repetition mechanism out of gear and ringing the hell or gong 35. The spring 10 is held against the side of the saw-frame 6 by means of a slotted clip 37, as shown in Fig. 4, and said clip acts as a washer also and is held in position by the nut 37, which is used to tension the saw-blade 6. In case the saw-blade breaks the clip 37 is released and allows the spring 10 to assume the dotted position shown in Fig. 4, and when the saw-frame falls the spring 10 no longer engages with the catch 11, but passes down beside it, and the saw-frame in this case is able to fall lower than it would if the spring 10 rested on the catch 11, and therefore the saw-frame in this case engages with the curved piece 38, (shown in Figs. 3 and 4,) which is acted on to move the belllever 33, thereby moving the bell-lever, as before described, and the effect of this is to set the bell ringing if the saw breaks.
In case only a single cut is required or a single piece to be cut from the material the catch 11 may be pushed to the left-hand side of the inclined piece 36, (shown in Fig. 4,) and in this case the spring 10 does not engage with said catch, but passes down beside it, and the saw-frame descends, as before described, until it engages with the curved piece 38 and rings the bell, as before.
Fig. 5 shows the raising-lever 20 and the stop 23. The rod 39, on which the stop is mounted, passes through a hole in the lever 40, which can be readily attached to it by means of a set-screw, and the lever 40 is connected by a link 41 with the raising-lever 20. The effect of this construction is that when the raising-lever 20 is raised by the camwheel 19, so as to raise the saw clear of the material, the stop 23 is caused to move to the left until it comes opposite the end of the material as it is fed forward. When the raising-lever 20 falls in lowering the saw onto the material, the stop 23 moves to the right until it is clear of the end of the material, thus preventing any possibility of the detached piece of the material jamming between the stop and the saw-blade and breaking thelatter.
The pressure of the saw on the material is regulated by the weight 42, (shown in Figs. 1 and 2,) which is supported by a knife-edge device 44 from a rack 43, which may take the form of a screw for convenience in manufacture. A forked link 45 is freely pivoted about a point on the weight, as shown, and is provided with a knife-edge arm 46, which also rests on the rack, and the efiect of this arrangement is that as the inclination of the rack to the horizontal is changed by the raising of the saw the weight moves to the left one tooth of the rack. When the inclination of the rack is again changed by the falling of the saw, the link 45 advances one tooth. Thus the weight advances one tooth after each piece of material is cut off and slowly increases the pressure on the saw, so as to compensate for the blunting of the latter through use. The falling of the saw-frame, however, maybe checked by any suitable devices.
Having fully described my invention, I claim as new and desire to secure by Letters Patent 1. A sawing-machine comprising a frame having a main shaft, and vise-jaws one of which is movable, a vertically-movable sawblade car ier mounted on said shaft, devices for feeding the material to be sawed transversely of the frame between the vise-jaws, a sprocket-wheel mounted on the main shaft, a cam sprocket-wheel mounted in the opposite end of the frame, means for gearing said sprocket-wheels in connection, and devices in operative connection with said cam-wheel for raising the saw-carrier, substantially as shown and described.
