Patented h'ov. 23, lily/3th Application filed August 30, 1917. Serial ifio. 188,981. Renewed September 30, 19%). serial No. $33,996.
To all 11:71am. if our 2 concern.
Be it known that l, THQMAS S. hiloGUinn, a citizen of the United States, and residing at Carlisle, Cumberland county, State of Pennsylvania, have invented certain new and useful Improvements in Grinding- Machines, of which the following is'a speci fication.
This invention relates to improvements in grinding apparatus, especially to apparatus for grinding large irregular metal surfaces such asthe surfacesof castings, and has for provide a device of this class which is convenient to operate, simple in design, and in which the dust from the rapidly rotatin grinding wheel is conducted away without coming in contact with any of the bearings of the grinder to injure the same.
The invention will be fully disclosed in the following description taken in connection with the accompanying drawings, in which,
Figure l is a perspective view of the apparaths;
Fig. 2 a riongitudinal section of a portion of the same, and
Fig. 3 is a section along line 3-3 of Fig. 2.
In grinding castings or other articles having large irregular surfaces, it is necessary that the grinding disl: be so held by the apparatus upon which it is mounted that it may be raised and lowered and moved from side to side in order that the various surfaces of the casting may he reached thereby.
It is very desirable also that the dust and grit caused by the act of grinding he caught and conducted some point where it may be liberated without damage to either the health of the operator or the bearings of the apparatus.
My invention combines in a novel inanncr such an apparatus suspended from above so as to have great freedom of movement, with a suction attachment which conducts the dust and grit awiiy whatever the position of the grinding apparatus.
The frame 10 of the grinder comprises a fan housing ll. having secured to one side the mot r supporting bracket 12 and to the other side the tubular casing 13, which .has a swivelconnection to a short tubular casing 14f rigidly secured to the gear casing 15. This frame. which supports the mechanism of the grinder, is supported from a lined member 10 above, such as a heann-hy a long away from the machine to rod 17 having swivel connectionat its ends with yolres 18 and 19 which are pivoted respectively to the member 16 and to brackets 20 projecting from the fan housing ll.
This connection allows the frame to be swung in a circle, tipped up and down or moved backward and forward as desired.
The yoke 19 is pivoted. to the frame at such a point that the portions oil-either side thereof balance each other so that the same normally remains in a horizontal position, but may be moved when slight pressure of the hands is exerted upon the handle 21,
secured to the gear casing 15.
lhe electric driving motor 22 is secured to the motor bracket12 in any suitable way as by bolts and has its shaft 23 alined with. 1
the tubular casing 13. The power shaft 24 is connected to the motor shaft 23 by any desirable form of flexible coupling 25 which takes care of any defective alinement. flhis shaft 24- extends through the wall of the;
fan housing 11 and. through the casing 13 and 14: into the gear casing 15 where it is journaled upon roller bearings 26. The shaft 2 1- is not journaled where it passes through the fan housing, but packing 2'? surrounds the shaft at that point to provide a tight joint.
Upon the end of shaft 24 opposite the motor and within the gear casing is mounted a bevel gear 28 which meshes with a bevel gear 29 mounted upon a short shaft 30 upon which the grinding disk 31. is se cured. l'his disk shaft 30 is right to the ower shaft and is journaled upon roller bearings 31" within easing The grinding disk hicb. is parallel to the power is rotated so that the dust and grit which iiy tangentially from its surface at the point of contact with the casting, will fly toward the body of the apparatus, as inoieated by the arrows in the drawings, instead of toward the op erator who stands on the other side. sheet metal hood 32., secured to the gear casing protects the operator from particles which fly upwardl -To collect and dispose of the grit and dust I provide the casing let with a branch having an opening 345 in its end, which is close to the grinding disk and is an intake funnel for the suction conduit to which it is connected.
This suction conduit comprises the casing 13 and the fan housing 11 with its downinterlocking flanges of sleeve 39 and collar 4O preventing the sections from coming apart longitudinally. This joint permits the disk to be rotated in a plane perpendicularto the shaft 24.
It is to be noted that the dust is removed from the grinding disk. without coming in contact with the bearings of the apparatus and this is important, as the "lit will injure and "destroy the bearings if it comes in contact with them.
As grinding disks 'of'dilferent sizes are used, and asthy also decrease in size by wear, it is desirable that thelower part of the mouth of the suction funnel be adjustable. so 'thatthe opening may-be varied and the work not interfered with. I make the portion 41 of the funnel adjustable by hinging it at 42, the slot'and thumb screw 43 being provided for holding the hinged portion in any desired position.
To. balance the apparatus when grinding wheels of different sizes and Weights are used, iron weights 44 may be placed on or removed from the horizontal bar 45 in rear of the motor. So long as the motor operates to drive the grinding wheel the fan will operate to remove the dust, and the suction action of the dust removing apparatus will not be interfered with whatever the position of the grinder.
Adjacent and within the bearing 26 is a disk 44 through which the shaft passes and which prevents-dust from passing into the gear box. It will be noted that the casing is thus closed at both ends and that the shaft bearings are outside the casing and unaffected by the dust and grit from the wheel, which is an important feature of the invention What I claim is: In a balanced grinding apparatus, a oasing having a fan compartment and a tubular. exhaust duct extending forwardly therefrom, a motor support and motor in rear of the casing, a grinding disk at the forward end of the exhaust duct, a shaft extending from the motor through said fan. casing and duct to the grinding disk, a fan on said shaft, said duct having dust inlet openings adjacent the grinding disk and delivering the dust to said fan, and means for.
varying the area of said dust inlet. f
In testimony whereof I afiix my si nature.
THOMAS S. MoG IRE.
