DRIVING MECHANISM.
Application filed July 81, 1922. Serial No. 578,656.
To all whom it may concern:
Be it known that we, MATTHEW S. CUM- Nnn, a citizen of the United States, and a resident of Brooklyn, Kings County, and State of New York, and FREDERICK W. GinssnNHAINnn, a citizen of the United States, and a resident of Freehold, Monmouth County, and State of New Jersey, have invented certain new and useful Improvements in Driving Mechanisms, of which the following is a specification.
This invention relates to driving mechanism and more particularly to means for supporting and directing driving belt.
In certain types of machines such, for instance, as thread cutting machines and grinding machines or hob grinders the cutting member is adjustably mounted for operation in a plurality of planes and at a plurality of. angles. This relatively wide latitude of adjustment requires a correspondingly wide latitude of adjustment for the driving mechanism for the cutting tool.
One of the objects of the invention is to provide adjustable power transmission mechanism for use in connection with machine tools by means of which a wide latitude of adjustment may be obtained.
Another object of the invention is to provide adjustable supporting and directing means for a driving belt so constructed and arranged as to be capable of quick adjustment to the desired position.
Another object of the invention is to provide adjustable supporting and directing means for a driving belt so constructed and arranged as to be rugged and firm when the structure has been adjusted to the desired position.
Another object of the invention is to provide belt supporting and directing means so constructed and arranged as to support the belt in proper driving position with reference to the tool driven thereby in all positions of adjustment of the tool.
Further objects of the invention will appear from the following description taken in connection with the drawings which form a part of this application and in which,
Fig. 1 illustrates in end elevation a machine having belt supporting and directing means constructed in accordance with the invention.
Fig. 2 is a rear elevational view construction shown in Fig. 1.
Fig. 8 is a front elevational structure shown in Fig. 1.
Fig. 1 is a sectional elevation showing the upper end of the upright post and the clamp and adjustable connections between the clamp and the yoke or bracket in which are mounted idler pulleys.
Fig. 5 is a sectional elevation taken substantially on line 55 of Fig. 1, and
Fig. 6 is a sectional elevation illustrating another form of connection between the upright post and the bracket secured to the bed of the machine.
The invention briefly described comprises belt supporting means intermediate the drivmg shaft and the driven shaft and having mounted thereon means such as idler pulleys for supporting and directing the driving belt. In the particular form of the in vention illustrated the supporting and directing means is carried by an upright post which is adjustable in a plurality of directions .with reference to the bed of the machine on which the device is mounted and the supporting means is connected to this post in a manner to permit'universal adjustment between these parts. The device, therefore, permits a wide latitude of adjustment and by means of the device the driving belt may be directed always at the proper angle with reference to the driven and cutting tools.
Referring to the drawings the device is illustrated as mounted on a cutting or grinding machine 10 having a bed 11 upon which are mounted the usual tail stock 12 and face plate 13. The work is supported between the face plate and the tail stock and is operated on by any suitable connecting mechanism and in the particular embodiment of the invention shown the cutting mechanism comprises a grinding wheel 14 mounted on a shaft 15 rotatably supported in bearings 16carried by bracket or bearing block 17. The block 17 is in turn mounted on a carriage l8 and as shown at 19 is arouately adjustable, the are being drawn of the View of the extends around a pulley about an axis normal to the axis of the cutting wheel. This construction permits the angular adjustment of the cutting wheel whereby the angle of cut in the work may be varied. In order, however, to effectively drive or rotate the cutting wheel in all positions of its angular adjustment, a particular form of belt supporting and directing means has been designed. This construction will now be described.
A shaft 20 is supported in brackets at the rear of the machine and has mounted thereon a pulley 20 which may if desired be carried by a sleeve and is driven from any suitable source of power. The pulley 20 is belted to a pulley 21 carried by a counter shaft 22. The counter shaft 22 is journaled in arms 23 secured to the shaft 20 and for the purpose of counterbalancing the weight of the shaft 22 and arms 23, a bracket 24 is secured to the shaft 20 and this bracket has adjustably connected thereto a counterweight 25. The shaft 22 is driven by the pulley '21 and this shaft in turn drives a drum 26 mounted thereon. The drum 26 is connected by a belt 27 to a pulley 28 carried by the shaft 15 upon which is mounted the rotary cutter.
other suit- It will be understood that any able driving means may be provided for driving the drum 26.
The belt 27 at the other end of its loop 28 carried by the shaft 1-5 and thereby drives the cutter 14.
The belt supporting and positioning means is carried by the machine frame intermediate the counter shaft 22 and the driven shaft 15. This means comprises an upright post 30 having its lower end mounted in a member 31 forming one half of a two part adjustable connection 32 and 33. The parts 32 and 33-are'pivoted with respect to each other on an axis 34 and have interengaging and coacting surfaces provided with radial notches or serrations 35. The part 32 is provided with. arcuate slots 36 through which extend bolts 37 threaded into and carried by'the part 33. This construction permits a swinging adjustment of the post 30 about the axis 34 as a center. I
The member 33 has formed on its opposite end a serrated circular plate 38 adjustably connected in the manner just described with reference to the parts 32 and 33 to a corresponding circular plate 39 formed on a bracket 40 secured to the bed of the machine. This last adjustment permits a swinging adjustment of the post 30 and part 31 in a direction at right angles to the axis 34.
A clamp 41 is mounted for rotatable or angular and slidable adjustment on the upper end of and encircles the post 30 and has adjustably connected thereto, by a ball or pulleys 45.
and socket connection 42, 43, a bracket or yoke a l in which are mounted idler sheaves The ball 4:2 has its shank as swiveled as shown at 4:7 to the yoke. Thus a universal and swivel connection between the clamp and the yoke or bracket 14 is provided.
From the foregoing description it will be seen that the belt 27 can be maintained at all times in the correct driving position with reference to the cutter shaft 15 and that by means of the various adjustments described, the belt drive may be at all times properly directed to obtain an efficient driving action. For instance, when the cutter and motor shaft are arcuately adjusted to fit a different angle of cut, the yoke 14': may be swung to any desired angle loosening the nut 18 which clamps the ball and socket connection. If ne'essary the post 30 may be swung longitudinally or transversely of the machine or driven shaft to secure the proper positioning of the yoke 44.. If desired the ball and socket connection 50, 51 shown in Fig. 6 may be substituted for the connection shown in Figs. 1 and 2 between the lower end of the post 30 and the bed of the machine.
Although certain specific embodiments of the invention have been particularly shown and described it will be understood that the invention is capable of further modification and that further changes in the construction and in the arrangement of the various cooperating parts may be made without departing from the spirit or scope of the invention as expressed in the following claims.
What we claim is:
1. Belt supporting and directing means comprising a post angularly adjustable in directions at right angles to each other, means for rigidly securing said post in adjusted position, a clamp mounted on said post, a bracket mounted on said clamp and having a universal connection therewith and idler pulleys mounted in said bracket.
