appiieation ined February?, 1914. serial. No. 817,104.
To all whom it may concern Be it known that I, AUGUs'r I'Ioniini., a citizen of the United States, and residing at New York city, county and State of New York, have invented certain new and useful Improvements in Grintling-liacliiiies, of which the following is a specification.
` This invention relates to a grinding maparticularly designed to impart a straight surface grain to metalor other articles.
- bodying my invention,
' apron 15 traveling over said tab vforms a support for the article to be ground.
'in the travel of the belt whic The machine comprises briefiy stated, an endless grinding apron running over a pair of drums, one of which acts as an apron tightener and is provided with means for imparting to the same, a slight inclination relatively tothe other drum, such inclination p imperfection would otherwise tend to run the apron sidewse off the drums.
VInthe accompan ing drawing: Figure 1 is aside elevation o a rinding machine emgFig. 2 a plan thereof,
Fig. 3 an end view, and Fig. 4 a detail of being designed to correct any lthe tension-releasing handle.
. In a suitable bearing 10 of a frame 11 is journaled a shaft 12 which receives motion through a. suitable pulley 13. Shaft 12 carries a relatively fixed roll or drum 14 that is engaged by an endless grinding apron 15 made of any suitablev material and covered by an appropriate abrasive coating. Apron 15 ensgiges a second roll or drum 16 carried by a aft 17 that is journaled in the forked end 18v of a' rod or plunger 19. The latter is slidably mounted in a pair of bearin 20, 21 depending from a table 22 that orms part of the machine frame. Table 22 is arranged intermediate drums 14, 16` and its upper surface extends substantially ta`ngentia ly to said drums, the active u per run of l; that thus To plun r 19 is clamped, by screw' 23, an adjustab e collar 24 between which and bearving 20, there is interposed a spring 25 that tendsto force drum 16 outward, thereby tightening ron 15. To collar 24 is pivoted at 26, a andle 27 carrying an eccentric 28 that is adapted to engage bearing 21.
Normally handle 2T occupies the position shown in Figs. 1 and 2, so that spring is free to advance drum 1G and thus stretch belt 15. iVhen the'lhtter is to he exchanged, handle 27 is swung outward whereby eccentric 28 is brought into engagement with bearing 21 to retract the plunger and drum 1'6 thus slacking the apron.
In order to insure a straight run of the apron during operation, means are provided for adjusting drum 16 relatively to drum '14 which adjustment is desirable for the reason that endless aprons when not quite true, have a tendency to run sidewise ofi the drums. It is this tendency which I have succeeded in checking by slightly setting the shaft 17 of drum 1G out of parallelism with the shaft of drum 14, such setting counteracting the running-off tendency of the apron. These means are shown to consist of a pair 'bf opposed adjusting screws 29 vtapped into lugs 30 of frame 11. Screws 30 engage a projection 31 extending laterally from one of the Shanks of fork 18. By manipulating these screws, this fork will be tilted to correspondingly tilt. drum 16 and thus insure the proper adjustment of the belt as will be readily understood.
I claim:
1. A grinding machine of the character described, comprising a frame, a first drum journaled therein. a second drum, an endless grinding apron engaging said drums, spring'controlled means for forcing the second drum away from the first drum, thereby tightening the apron, and means for tilting the second drum relatively to the first drum.
2. yA. grinding machine of the character described, comprising a frame, a first drum 'ournaled therein, a second drum, an endiess grinding apron engaging s aid drums, spri -controlled means for forcing the aecond rum away from the first drum, means for tilting the second drum relatively to the first drum, and means for rendering inactive the first named means.
3. A grinding machine of the character described, comprising a frame, a first drum journaled therein, a second drum, an endless grinding apron engaging said drums, a plunger having a fork in which the second neem@ drum is` joumaled, .c teble emenged below set scewtupped into the frame and engagthe uppelr` a ron run, a pair of bearings ening the fork, whereby the second drum may gaged by t e plunger, e coller edjustably be tilt/ed relatively to the first drum.
