AUTOMATIC SLIDE COVER.
Application led August 3, 1925. Serial No. 4*?,El52- The purpose of this invention is to provide automatic means t'or protecting the ways of a planer, or like machine having a reciproeating bed, from dust and chips resulting: a trom the operation oi' the machme upon any given piece ot' work. It conslstsot certain :leatures and elements of construction here inalter described and shown in the drawings as indicated by the appended claims.r
Figure l is a perspective side view of a jointing machine with du'st-protecting,n sllde covers or aprons applied thereto in accordance with this invention.
Figure 2 is a direct side'elevation of the machine with some parts omitted or shown only in dotted outline.
Figure 3 is a vertical detail section taken i as indicated at line 3--3 on Figure 2.
Figure 4 is a top plan viewof one end of the machine showing the take-up roller for the aprons and parts associated therewith.
For" purposes ot illustration the drawings show a simple form ot jointer of the au type employed in working and polishing stone. rllhe principlesof the invention, hoW- ever, are equally applicable to metal-Working machinery and many other mechanisms in which upwardly open guideivays or runways are provided for a reciprocating member such as the Work-carrying bed ot a planer. lin such structures the deposit of grit, dust or metal chips on the guideways and the resulting rapid abrasion of the Ways, 2, causes them to Wear to such a degree as to seriously impair the proper alignment and smooth Working oi the parts, requiring expensive retinishing and readjustment of the Ways and loss ot Working time for the machine as a Whole. This is particularly true of stone- Working machinery because of the gritty nature of the stone dust thrown olf from the work. v
ln the machine illustrated the base casting, 1l supports the reciprocating bed, 2, on horizontal guideways, 3, which are shown as ll-shaped grooves, and for protecting these grooves from dust and grit I provide iiexllole strips or aprons, 4, which are secured by clamps, 5, to the opposite ends respectively of the movable bed, 2. At each end of the base there is rotatably mounted a take-up roller, ti, upon which the end portions of the aprons, 4, are Wound. dAround the middle portions of each ot the rollers, 6, l have shown several turns of a flexible member such as a rope or cable, 7 the intermediate portion of the rope, 7, passes over a pulley, 8, which is attached to the end ot' a second rope or cable, S), passing around Ltruiden pulleys, 1() and 11, supported in fixed position by a post, 12, standing at a short distance from one end ot the planer and in line there with. Any suitable form. ot' yielding tensioning means may be used in connection with the cable, 9, for keeping the cable, 7, tightso that it will windup the aprons, 4, on one ol the take-up rollers, (i, as the bed2, approaches the roller, While the other roller, G, is permitted to pay out its aprons, 4,\at the other end of the bed, 2. lhe tensioning means shown is in the t'orm ot a Weight, 13,
suspended by the cable, 9; with this arrangement the pulley, will undergo practically i no movement because the rope, 7,' will unwind from one of the rollers, 6, at the same rate at which it is Wound upon the other during the major portion olf the strolre et the bed, 2.
As indicated in Figure 2, the `machine may be adjusted so 'that the end of the bed, 2, will travel beyond the end of the Ways, '3. For this reason the guide'rollers, 14, over which the aprons pass at each end of the Ways, 3, are mounted in swinging frames consistingl of side bars, 15, and a cross har, 16, pivotally mounted at their lower ends on a crossrod, 17., which is supported on the bracket arms, 18, which also carry the'roller, 6. lt will be understood that the under side ol the bed, 2, is formed with the usual ribs for engaging the guide grooves, 3, Whereas the aprons, 4, extend normally'in planes just above the grooves, 3. Therefore, the rollers, 14, extendnormally in the path of the down- Wardly extending ribs ot the bed, 2, and are struck by said ribs as the bed moves beyond the end of the base, 1. By this encounter the :trame arms, 15, are swung away from the base, l, about pivot, 17, as shown in Figure 2, thus permitting the ribs of the bed to pass over the' rollers, 14. In this portion of the stroke the aprons, 4, may even be carried oli' the rollers, 14, but are heldin tension by the take-up rope, 7, and Winding rollers, 6. As the bed, 2, returns, the aprons,
lill
lill] 4, again engage the rollers, 14, and swing back the frame bars, 15, to their normal vertical position Aagainst theAend of the base.
Thus throughout the reciprocating movement of the bed, 2, the upwardly open runways, 3,' are kept covered bythe aprons, 4, extending from the ends of the bed, 2, while the bed itself covers the intermediate portion of the ways. Thus a large percentage of the dust and grit is effectively excluded from the ways, 3, and their useful life is greatly prolonged, and particularly in stone working operations requiring the grinding tool to be flushed with water, the water is kept ont of the ways 3, by the slide covers or aprons 4, and proper lubrication of the ways Y is thus facilitated.
1. In a machine having a reciprocating part-with an upwardly-exposed runway on which it travels, a pair of flexible aprons extending rom opposite ends of the reciproeating part respectively for coveringthe exposed portions of the runway; a take-up roller for each apron around which the end portion of the apron is wrapped in direction to be wound up asthe reciprocating part moves toward the end of the runway which the apron covers, and m'eans interconnecting the take-up rollers for winding up one apron as the other unwinds.
2. In a machine having a reciprocating part with an upwardly-exposed runway on which it travels, a pair of take-up rollers disposed at opposite ends of the runway respectively, a pair of aprons extending from opposite ends of the reciprocating part for covering the exposed portions of the runway and arranged to be Wound on said rollers respectively, a flexible member whose opposite ends are wound on-said rollers respectively in directions opposite to the winding of the aprons, whereby unwinding of said member will rotate the roller in direction to wind upeits apron, and means operating between the ends of said flexible member to maintain it in tension between the rollers.
3. In a machine having a` reciprocating part with an upwardly-'exposed runway on which it travels, lexible aprons extending from said-part in opposite directions to cover the exposed .portions of the runway, take-up rollers for said aprons respectively, and a fiexible member. having its opposite ends wound upon said take-up rollers in direction for causing one roller to wind up its apron as the other apron unwinds; a pulley engaging said flexible member intermediate its ends, and yielding tensioning means at.- tached to said pulley.
