LAP-STAND.

Specification of Letters Patent.

Patented June 22, 1915.

To all whom it may concern 7 Be it known that I, HIRAM D. TURNER, a citizen of the United States, residing at Manchester, county of Hillsboro, State of New Hampshire, have invented an Improvement in Lap-Stands, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to improvements in lap stands for carding machines and is designed with a view to facilitating the introduction of the roll of lap into its supporting guides at the admission end of the carding machine and also to facilitate the piecing of the end of a new lap upon the end delivered from an exhausted roll.

In the usual form of carding machines the rod which forms the axle of the roll of lap is inserted in slots in brackets extending'upwardly from the admission end of 7 the carding frame and thelappermitted to rest upon a driven lap roll whereby it is delivered over the feed plate to the feed roll and thence'by the licker-inmechanism in the usual manner. The end brackets usually are provided with posts having supplemental brackets having journals adapt ed to receive the axle of a spare lap which is retained therein until the active roll of lap is exhausted, whereupon the attendants lift the lap from the last mentioned brackets and drop it into active position upon the lap roll.

In order to position the end of the new lap so that it may properly be matted with the end of the preceding lap which is being fed into the carding machine it is frequently necessary to turn the lap which is being introduced forward or backward so that the ends of the laps may be united without forming a ridgeor a thin place in the web which is being fed to the carding machine.

One of the objects of the present invention is to provide means for supporting a spare lap in such position thatit may be transferred easily into active position without the necessity of touching'the material upon the lap thereby avoiding injury to the same. a

Another object of the invention is to provide means for. rotatably supporting the lap which is being introduced a suflicient distance above its active position to afford accessto the edge of the new lap and to permit it to be placed properly relative to the end of the next preceding lap.

Other objects of the invention and the nature thereof will more fully appear from the following description and the accompanying drawings and will be pointed out in the annexed claims.

In the drawings: Figure 1 represents the admission end of the usual carding machine with the improved lap support applied thereto, Fig. 2 is an end view of the same centrally broken away.

As illustrated in the drawing herein the admission end 1 of the usual carding machine frame is provided with a bracket 2 having a vertical slot 3 in which the rod or axle a of the active roll of lap 5 is adapted to rotate, the lap being supported upon a lap roll 6 and being delivered therefrom is further advanced by a feed roll 7 to the licker-in and thence to the cylinder.

It is to be understood of course that each side frame of the machine is provided with similar brackets and that the lap stand hereinafter to be described comprises duplicate or complementary parts arranged upon said end frames so both ends of the lap will be simultaneously supported and moved.

The brackets 2 are provided adjacent their upper endsand upon thesides of the slots toward the carding machine with bosses 8 having vertical apertures to receive and support vertical standards 9 upon which means are mounted for supporting a spare lap.

The preferred means illustrated herein com to cause the handles 14 to move in unison and also provides means for supporting the spare lap in elevated position as will hereinafter appear.

The ends of the arm 5 are desirably bifurcated, oneof the fingers of said bifurcation 18 being curved into hooked form adapted to receive the rod or axle 4 of the lap while the other finger 19 is extended at an angle to the axis of the portion 5 of said lever to provide a guiding means for directing the axle 4 into the slot 3 in a manner hereinafter to be described.

The axis of the extension 5 is disposed at such an angle to the axis of the handle member 14 that when the latter is in depressed position the axle of the lap which rests in the bifurcation of said lever will be on the saine side of the vertical axis of the standard 9 as the rod or stop which connects the levers or handle portions v14 whereby said rod or stop will be pressed against the sides of the standards 9 to support the spare roll in elevated position.

When the material upon the active lap has become exhausted the empty axle is re moved from the vertical slot 3 to permit the introduction of the spare lap. The handle 14: is thereupon raised and the spare lap carried about the pivotal support 13 until the member assumes the depending position shown in dotted lines in Fig. 1 at which time the axle of the roll is supported by the hooked finger 18. WVhen in this position the lap is free tovbe rotated in such a manner that the end thereof may be wound or unwound and easily pieced to the preceding lap.

When the laps, have been pieced the bandlelt is thrown still farther over to the 7 left beyond the position shown in Fig. 1,

whereby the ends of the, axle of the lap will be caused to contact with the side of the standard Sadjacent to and above the slot 3 forcing said axle out of its engagement with the hooked members 18 and permitting the lap to drop into active position the axle of the "roll being guided and steadied in its descent by the inclined finger 19.

It will be observed that the mechanism a above described provides a convenient means for supporting the spare lap and transferring the same into active position in the carding machine.

It is to be understood that the mechanism described herein is one of the preferred forms of my invention but that this invention contemplates broadly means for supporting a lap "or like device in proximity to its active position, and means for moving thesame thereover into active position in com risin means for su ortin a la in active position, pivotally mounted means for supporting a spare lap conveniently near said; active positionand adapted upon rotation to position said spare lap in the vertical plane of the active position but reactive position, adjustable means rotatably.

mounted abovesaid position for supporting a spare lap above said active position and for swinging the same adjacent to but sufiiciently removed from said active position to perinitthe end of the lap thereon. to be conveniently pieced to the next preceding lap.

1. In an apparatus of the class described com risin means for su ortin the la in active position, pivotallymounted meansfor supporting a spare lap above said active po- SltlOIlflIldfor swinging the same ad acent to but sufliciently removed from said active positionto permit the; end of the lap to be conveniently pieced to the next preceding lap and means for transferring said roll to active position.

5. In, an apparatus comprising a. frame having slots to receive the ends of the axle of a roll of lap and to maintain the same in active position,supporting standards adjacentto said slots, a pair of angular levers pivotally mounted at their elbows on said standards eachhaving at one end a hooked member to engage and support the axle of the lap and at the opposite end a handle, a stop carried thereby adapted to engage the side of the standard whereby the axle of the lap when in raised position will be on the same side of the pivotal support as said stop.

6. A lap stand comprising a frame having of the class described slots to receivezthe ends of an axle of a roll of lap, standards supported by said frames, members pivotally mounted upon said stands and having means adapted to engage and support the axle of a roll of lap, handles extending from said members at an angle to the axial plane and means carried by said handles adapted toengage said standards to supportsaid lap in raised position.

7. A lap stand comprlsinga frame having slots to receive the ends of an axle of a'roll of lap, supporting standards, members having bifurcated ends pivotally mounted upon said standards, one'arm of each of said bifurcated ends being hook shaped to support the axle of a lap roll when in elevated or depending position and means for supporting 1 0 said member in elevated or depending positions.

8. A lap stand comprising supporting standards, a pair of angular levers pivotally mounted at their elbows upon said standards and each having hooked ends adapted to engage the axle of a lap roll, means connecting the opposite ends of said levers adapted to engage said standards to maintain said lap roll in elevated position and providing means for rotating said hooked ends simultaneously into depending posi tion. a

9. In an apparatus of the class described comprising a frame having slots to receive the ends of an axle of a roll of lap, standards secured to said frame adjacent to said slots, brackets on said standards, levers pivotally mounted upon said brackets in the plane of said slots and having bifurcated Copies of this patent may be obtained for five cents each, by addressing the ends consisting of hooked short arms and oblique long arms, handles upon the oppo site ends of said levers and means connecting said handles adapted to engage the sides of the standard to maintain the lap roll in elevated position and providing means for rotating said hook shaped ends into depending position and upon further movement for displacing the lap roll from the hook shaped member and by the action of the inclined arm steadying the same as it is delivered into the slots in the frame.

In testimony whereof, I have signed my name to this specification, in the presence of tWo subscribing Witnesses.
