JQHN GOLDENBERG, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TO SAMUEL COHEN, OF SAME PLACE.

CLOTH-SPREADING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 564,989, dated August 4, 1896.

Application filed April 29, 1895. Renewed January 13, 1896. Serial No. 575,390. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN GOLDENBERG, a citizen of the United States, residing in the city and count 7 of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Unrolling or Spreading Cloth or Similar Material Prior to Cutting, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of novel details of construction, all as will be hereinafter set forth.

Figure 1 represents a perspective view of an apparatus for unrolling cloth or similar material embodying my invention. Fig. 2 represents a broken front elevation of the same, showing another form of supporting devices for the apparatus.

Similar letters of reference indicate corresponding parts in both the figures.

Referring to the drawings, A designates a suitable bed upon which the apparatus is adapted to be mounted.

B designates abearing attached to said bed, in which is journaled the shaft of the gear C, the latter being provided with a crankhandle D. Said gear meshes with a pinion E, mounted. on the shaft F, which latter r0 tates in suitable bearings G on the said bed, said shaft F having mounted thereon near its ends the sprocket-wheels H, which are engaged by the sprocket-chains J which pass around other sprocketwheels K at the other end of the bed, said wheels K being mounted on a suitable shaft L, which is journaled in the bearings M.

N designates posts or standards which may be composed of pipe-sections, if desired, one of said posts being on each side of the bed and, in the presentinstance, inside the chains J, the latter having a connection J extending therefrom to the said posts N.

P designates a foot or base portion which is attached to said post, and is provided with the rollers Q, which run or travel in or on the tracks R, which are arranged substan tially longitudinally of the bed A.

S designates cross-pieces which serve as a brace for said posts N, and which assist to guide the cloth as the same is unrolled, said posts N being braced at their upper portion by means of the bar T, which is connected to each post N.

U designates bearings which are attached to suitable portions of said posts N, and have their tops open, whereby the shafts N can be readily placed therein, said shafts being prevented from lateral shifting by means of the collars X X on each end thereof. The said shafts W are each provided with a transversely-extending bar or rod Y, which has secured near its outer ends the forked pieces Z, portions of which engage the board or central portion A of the roll of cloth A which is mounted thereon, said pieces Z having pivot-ally attached thereto the rods B, which are pivoted to each other and to the central substantially horizontal rod C, whose free end enters the shaft W, which is preferably made of tubing, said rod G being held in the desired position by means of the setscrew D, whereby it will be seen that as the rod 0 is moved in or out of the shaft V the forked pieces Z will be caused to approach or recede from each other, since they slide freely on the rods Y, and so can be readily adjusted to support rolls or bales of cloth or other material of any size.

F designates a rod which is attached to,

the brackets G, which are mounted on said posts N, the function of said rod F being to hold that portion of the material which is being unrolled from the upper bale out of contact with the revolving roll which is below, as will be explained.

H designates clamps which are suitably attached to the bed A, and which have a projecting finger J, whose end L is adapted to engage the cloth as it is unrolled and hold the same in fixed position, as will be evident, said fingers being held in the desired position by the nuts K.

The operation is as follows: The crankhandle D being rotated, the engagement of the gear and pinion C and E will cause the sprocket-chains J to move either to the rightor to the left, and by reason of the connection 3 between the posts N and said chains, the said posts will be caused to travel either to the right or to the left, as desired, and it will thus be seen that if the free end of one or both of the rolls of the material A be attached to a fixed point, as N, and the posts N moved away therefrom, the said material will be readily unwound, and when the same has reached the extreme left of the bed by inserting the fingers L therein and holding the same rigidly in place by tightening the nut K the cloth will be held at that end of the board, and if now the posts N are caused to travel to the right another length or layer of the cloth will be unwound, and so on until all the cloth is unwound from the rolls, the clamping or holding devices being readily adj usted to rolls of diiferent sizes by loosening the set-screws D and moving the rods 0' in or out of the shafts IV, as is evident, and said shafts WV can be readily inserted in their bearings U, as will be evident, the rod F serving to hold the material of the upper roll out of contact with the lower roll as thesame is unwound, while the rod S serves to hold the cloth from both rollsin proper position while it is being unwound, said rods S, F, andT serving also to brace the posts orstandards N, as is. evident, the material being thus unwound-and superimposed upon the table in layers ready for cutting.

Itwill be evident that power may be ap plied to the I shafts F and L in any suitable manner and that various changes may be made in the manner of assembling the differout parts of the above apparatus, which will come Within the scope of my invention, and I do not, therefore, desire to be limited in every instance to the exact constructions I have herein shown and described.

In Fig. 2 I have shown another form of supporting devices for the roll or bale of cloth, A designating the cloth, as before; Z, one of the forked pieces supporting the same; B O, the adjusting devices; W, the shaft, and N one of the posts or standards in which said shaft is mounted. 'lhestandN has a foot A"- attached thereto, which rests upon the portion 13 of the block C the parts being held "in position by means of a suitable thumbscrew D or similar device which passes through slots in said portions A andB The lower portion of said block C has journaled therein a roller D which is adapted to contact with the top of the table E said block having a depending slotted arm F against which is held theslotted arm G", which has,

the extension H attached thereto, inwhich is .journaled the roller J which contacts with the under side of the table E the parts F and G beingheld in position by means of the thumb-screws K the block 0 being suitably braced by means of the rod L It will thus beapparent from Fig. 2 that the posts N can be readily moved toward or away from each other, in order to adjust the apparatus to rolls of cloth of varying widths, and the rollers D and J 3 can bemoved toward or away from each other to accommodate tables of different thicknesses. Y

I desire to call especial attention to the adjustable attachment whereby the cloth is enabled to be sustained in a central position,

said attachment being capable of adaptation to rolls of varying sizes.

It will be evident from the foregoing that a very effective and efficient machine is thus obtained which is especially useful for spreading or unrolling cloth, goods, or similar material upon a table prior to cutting the same.

Having thus'described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a cloth-spreading apparatus, the posts N a shaft WV j ournaled on each of said posts, a transversely-extending rod connected with each of said shafts, the forked pieces Z movable on said rods, the rods 0 guided on said shafts, and the braces B pivoted to said forking piecesand to said rodsjO, said parts being combined substantially as described.

2. In a cloth-spreading device a bed, the posts I each having a slotted foot A the block C havingthe roller D bearing on said bed, the slotted portion B connected with said foot A the thumb-screw D and the depending slotted arm F the-slottedarm G carrying the roller J bearing against the urn der side of the said bed and the thumb-screw K said parts being combined substantially as described.

3. In a cloth-spreading apparatus,:a bed, posts adapted to support rolls of cloth thereon, having laterally-extending feet, blocks on which-said feet aresupported, means foradjusting said feet and blocks relative to each other, rollers journaled in said blocks, adapted to contact with the top of said bed, and arms F adjustable relative to said blocks, each of said arms having an extension thereon and a roller j ournaled in said extension, and adapted to contact'with the under side of said bed, substantially as described.

4. In a cloth-spreading apparatus, a bed, posts supported thereupon, shafts journaled on-said posts, cloth-holding devicesmounted onsaid shafts, blocks-having rollers journaled therein and adapted to contact with said: bed, means for connecting said blocks with said osts arms havin extensions thereon connected to said blocks, and rollers journaled insaid extensions also adapted to contact with said bed, substantially as described.
