To all whom it may concern:

Be it known that Homcn G, Dooumn, a citizen of the United States of America, residing at Knoxville, in the county of Mari on and State of Iowa, has invented new and useful Improvements in Wall-Paper Pastin and Folding Machines, of which the fol owing is a specification.

The to provide a machine having means for holding a supply of wall paper 1n a continuous row, then advancing the paper through a paste applying apparatus and finally folding the paper in the usual layers or folds for convenient handling when placing the same on the wall. Further the machine makes provision for measuring the length of paper pasted and folded and it is still further provided with means which will permit the formation of the supply roll from the individual rolls, the ends of the individual rolls being matched and secured together by an adhesive paper tape in the formation of the supply roll. The folding of the paper is accomplished by means of a movable platform,

this platform being mounted forreciprocating movement and the movement being accomplished by a crank handle which aside from being operativel connected to the table is also operative y connected to the pasting and advancing rolls by which the paper is conducted from the supply rolls to the table. Automatically operated clamping members are carriedby the table or platform and these clamp and securely hold upon the table the different plates formed in j the operationof the machine; Aside from the general purpose above mentioned, the invention further contemplates provision for an apparatus of the 'kind stated which is comparatively simple in construction, durable and effective in operation and inexpensive to manufacture.

Other and further purposes appear in the following description wherein-the invention is set forth in detail. To therexact construction in which it is shown and described, the invention is not to be restricted. The applicant reserves the right to make such changes or alterations as the actual reduction to practice may suggest, in so far as such changes or alterations are compatible in spirit with the annexed claims.

Fi re 10 is a section on the line 10-10 of Figure 9,

As illustrated, the invention comprises a main frame 1 of open construction and provided at their endwith transversely disposed bars 2 which are formed with openings 3. These bars are provided for the purpose of supporting a track for the work table which is. moved backward and forward in the operation of the machine and this track comprises two spaced rails 4 which are made preferably of round rod and formed with right angular bends at their terminals, these rightangularly bent portions passing through the bars 2 on their upper edges to have their extremities enter the openings3 in which nuts 5 are carried, the latter threadingly engaging the right angularly bent portions and bearing against the outer. sides of the opening 3, thus secuing the two bars or rails 4 inposition thereon, asis apparent in Figures 1, 2, 3 and 4 of the drawin v The work table which travels on the tra ks or rails 4 constitutes a platform 6 with depending side and end plates 7 and 8. On

'to the in pairs as shown in 3, each pair supporti an axle on which a peripheral vcd i loo or roller 11 is rotatably mounted. The platform 6 carries suflicient pillar blocks 9 to provide for four wheels or rollers 11 two adjacent one end and two ad acent the other, so that the platform may be moved backward and forward in the direction of the length of the frame 1.

Centrally disposed with reference to the platform 6 of the work table and depending from the bottom face thereof there is a plate-.12, this plate being formed with a slot 13 in the direction of its len h and being secured at its upper end tot e latform 6 b means of angles 14 attached 0th ge of the plate and to the underface of the platform b means of fasteners 15 which are preferab y lag screws. This.

plate 12 is the medium throu h which motion transmitted to the wor table and in order that it may be relieved from undue strain at its lower end, there are provided the dia nally disposed braces 16 which are secured hn opposite edges of the plate 12 adjacent its lower end and which are further secured to the underface of the platform ad'acent its opposite ends.-

e frame 1 of the machine on opposite sides and substantially at its longitudinal center carries the upright plates 17, between one of whichand the plate 12 a standard 18 is provided. The standard 18 adjacent its upper end and the plate 17 next to-it each carry a bearing 20 is journaled, this shaft 20 being formed with a crank portion 21 on the extremity of whichthere is loosely mounted a roller 22,.this latter working. in the slot 13 formed inthe plate 12. Obviously whenthe shaft 20 is turned, as it is inthe operation of the machine, a corresponding angular movement is imparted to the crank 21 with the result that the roller 22 is caused to travel up and down in the slot 13 as the crank rotates, thus rforce moving the work table first in one ection and then in the other along the tracks or rails 4.

On the outer face of the plate 17 in which its bearing is carried, the shaft 20 carries a sprocket wheel 23 and a turning crank 24 attached to it outside of the sprocket wheel,

there trained overthe sprocket wheel 23 a chain 25 which is also trained over a sprocket wheel 26, this sprocket wheel 26 being rotatably mounted on a stud 27 carried in the late 17 at a oint a substantial distance a ve the sha 20. In addition to the sprocket 26, the shaft 27 carries a second sprocket 28 which is also rotatably mounted on the shaft. This sprocket 28,

however, is provided with a turning crank 29 by which rotary movement may be readily im arted to it by hand. The sprocket 28 is for positive connection with the 19 in which the shaft swan-a sprocket 26 to the end that both may be rotated by means of the crank 29 but incarries a head 31 on the outer face of the. sprocket. This pin is of sufiicient length to enter a socket or hole 32 formed in the sprocket 26 and in order that the pin may be normally retained in the socket 32,:there relation to the is provided in surroundin pin a coil spring 33 whic bears one end against a transversely disposed pin 34 carried by the pin 30- and the other end To this end there.

a ainst the inner face of the sprocket 28.

hen the pin 30 engages the socket 32, a-

pin .35 carried by the head 31 seats in, a

socket prepared for it in the sprocket 28.

With the engagement of the pin 30 in the socket 32, the two sprockets. 28 and 26 be come positively connected so that any movement imparted to .the one is immediately transmitted to the other. The construction provides, however, for a disengagement of these two sprockets and this is accomplished by withdrawing the pin 30 from the socket 32 until the pin 35is freed from its socket. A slight angular movement then imparted to the head 31 will throw the pin 35 to a position where it may not enter its socket,

but its end will bear a ainst the-outer face the pin 30 will be of the sprocket 28 an withdrawn from its socket 32against the pressure of the spring 33.v The two sprockets 28 and 26 may then be readily operated independent of each other.

The crank 29 being the general operating medium of the machine, the sprocket 26 vided and is supported between the two 7 plates 17 at their upper ends, the cover 37 of the said reservoir carrying at its center a vertically disposed thimble or sleeve38' which is internally threaded to receive the screw stud 39 which is' formed with ahead 40 to permit its being readily turned for the.

purpose of elevating or lowering the screw stud. The paste reservoir 36 is formed with bottom and side walls which in cross section resent the segment a of a circle and :the

ottom at the lowest point is formed'with a plurality of longitudinal perforations 41 IMOJI? and thus provides for practically utilizing all the paste contained in the reservoir, since the contents of the latter w1l1 always float toward the lowest point and it is at this point that the perforations'41 are formed.

Of course it becomes eseential'to rovide some means to prevent the reservoir when the device is not in use and to this end there is within the reservoir a bar 42 which may be forced down into contact with the bottom of the reservoir or elevated from contact therewith. This bar at its center has a ivotal connection with the lower end 0 the screw stud 39 andif the latter is turned to lower, the bar is perforce brought into firm contact with the bottom of the reservoir when it effectually closes the perforations 41. When turned in a direction to elevate it, the bar is perforce elevated and being raised clear of the bottom the paste may flow under it and through the perforations.

Rotatably mounted directly below the reservoir 36 so. that it may receive paste flowing through the perforations 41 thereof, there is a feed roll 43 which is carried on an appropriate shaft one end of which projects far enough through that plate 17 in which the shafit 27 v1ils mountlfi tph rmlt its bein uippe wit a gear 1s gear being l e ash with a ar 45 carried on the shaft of a roller 46 w ich is similar to the roller 43 but which receives the paste from the roller 43 for transfer to the wall paper which is passed betweenthis roll 46 and a roll 47, the latter being of similar construction to the roll 46 but acting to hold the wall paper in close contact with the roll 46 so that the paste received from the roll 43 may be transferred to the back ofthe paper. The roll 43 is substantially a distributing roll. The paste reaching the roll 43 through the perforations 41, is not distributed over the surface of the latter but forms in rings thereearound until it reaches the roll 46,the contacting surfaces 'of the two rolls then serving to distribute the paste over them and the latter rolls transfer this paste to the wall paper paste between it and the roll 47 The roll receives its rotary motion by an operative connection with the roll 46, this operative connection being in register or counting mechanism to indicate shaft is journaled in two vertically disposed blocks 52 which are interconnected by means of rods 53, of which there are two, one disgglsed above and the other below the shaft.

ese blocks at their upper enda plate 54 on'whi are inscribed suitable indicia d toindicate in linear units the length of per passed over the roll 47. The two bloc 52 and rods constitute a frame which it attached to that plate 17 on that side of the machine where,the driving gears are carried and this frame is attached to the plate by having one of its blocks 52 secured thereto in any suitable manner.

The shaft 51, between the two blocks in which it is journaled, is provided with screw threads, as indicated b 55, and a movable coun medium is sli ably mounted on the rods 53 and provided with a threaded hole in which the threads 55 of the shaft 51 engage. This counting medium consists of the complementary blocks 56 and the bearing holes for the rods 53 and the threaded ho e for the threads 55 are formed half in one block and half in the other, the two blocks being detachably connected together by means'of a screw 57 which passes loosely through one block' and threadingly engages the other. Obviously when the screw 57 is tightened to secure the two blocks 56 firmly together, the turning of the shaft 51 will y 58 over certain indicia on the scale on the plate 54 will indicate the passage of a specied length of paper over the roll 47.- Directly below the roll 47 there is mounted a trimming couple for the purpom of removing the selvage edges from the wall paper and this trimmin con le consists of the rolls 59 and 60, eac of t ese rolls carrying a circular knife 61 adjacent one end and being formed against the other end with a peripheral ve 62. It will be ob served that the knife carried by the one roll plays within the groove formed in the other roll. The two knives are therefore carried adjacent the opposite ends of their respec tive rolls.

These two rolls 59 and 60 are carried on suitable shafts both of which are rotatably mounted in the plates 17 and operatively connected by meansiof intermeshlnggears 63. The shaft of the roll 59 protrudes a suflicient distance beyond its gear 63 to receive a sprocket 64. Movement is imparted to the'roll 59 through the sprocket 64 and to the the operative connection between the two rolls consisting of the gear couple 63 makes for the imparting of motion to. the roll 60.

parent from this construction that the turn-.

mg of the sprocket wheel 28 by means of its crank handle 29 will serve to put the trimming rolls as well as the feeding and pastin rolls in motion."

0 provide an adequate supply of paper for the operation of the machine, it IS mtended that a supply .roll shall be formed by joining end to end a number of the usual rolls. To this end there is provided on the frame 1 on either side thereof and adjacent late 17 on that side, a second plate or'stan dard 67, these two standards at their up 1- ends being formed with slots 68 in which a rod 69 may be supported so that it ma be readily removed when desired. This ro 69 is intended as a support for a supply roll, such as the supply roll 70'indicated.

in 5 the drawings. This supply roll 70 consists of a number of the usual rolls whose ends have been previously matched and connected together, provision being made for effecting this in a quick and easy manner, as

is explalned hereinafter, The two standards 67 aside from supportin the supply roll, also support a horizonta ly disposed plate 71, the level of the upper face of which is approximatel lower side of the roll 46. This plate acts as a support for the paper between the point where it leaves the supply roll and enters between the rolls 46 and 47. The two side plates 72 are carried at the ends of the plate 71 and serve as guides for the side edges of the-paper, thus ensuring it maintaining a certain position when passing between the rolls.

Below the roll a transversely disposed plate 73 is cal-seams plate being attached to the two plates 17 with its width disposed in a vertical plane. Below this plate 73 there are carried two transversely disposed bars 74, the two being spaced from each other and positioned one below the roll 60 and the other below the roll 59. The paper leaving the t rolls 59 and 60 passes before the plate 73 and between the two bars 74, being laid in folds uponthe work table as the latteris advanced to and from along its track A clamp is provided ad'acent each end of the work table for securing the folds of the same asthe level of the paper in place thereon as the paper is folded and each of these clamps comprises a pair of bell crank levers 75 secured together: in spaced relation to eachother by pins 76.

These clamping feet or levers 75 are pivotally mounted on the work table, each air between a pair of upstanding ears 77 w 'ch are attached to the work table. Connected with each pair of levers there is a contractile spring 78 which is attached one end to one of the pins 76 and the other end to the upper face of the work table, this pin being positioned adjacent the extremity of one arm of each of the levers. The'spring serves normall to hold the ends of the other arms of the be 1 crank levers in contact with a block 79 mounted on the iipper face of the work table. The spar-ate folds of paper, when the machine is being operated, are

held on the work table by these clamping. members and in order that each fold may be clamped down in turn, it is necessary to provide means for-raising the clamping memebers at certain times (1 the operation of the machine. To this en there are provided lifting arms 80 one of which is mounted on each bar 74 and disposed to project in the direction of one of the clamping members whose pin 76 to which the spring 78 is connected, is provided with an extension 81 projecting laterally from. the side of the clamping member. The lifting arm 80 is= shaped so that as the clamping member ad-I vances toward it the extension 81 which pro- 7 j ects laterally from the side of the clamping member may ride up on the arm, thus ra1smg the clampin memben' Each clamping I member is raise to permit a fold of paper to be placed thereunder at the time its end i of the work table is brought to-the longi-;

tudinal center of the main frame 1.

In addition to the clampin members,

there are provided transverse y disposed tion 83 in which there is formed sloop-like 1 crank portion '84. This wire or rod is pivotally mounted on the work table, the vertically disposed portion 83 passing throu h a pair of spaced bars 85 between which t e crank portion 84 stands; This crank porof the vertical portion 83 but will permit tion 8s precludes longitudinal movement pivotal movement thereof. A right angularl Y disposed portion 86 constituted the fol engaging finger and projects over the *1 top of the work table, being normally disposed in the direction of the width of the latter. The fold engaging finger86 is designed to move in either direction on thepivot point of the vertically disgpssed portion 83 the crank portion 84 being posedina;

lane at right angles to the plane of ther 86 and a tension spring 87 bein attached between this crankportion 84 an a plate 88 spanning the bars 85. p The spring The work tab e carries four of these fold engaging fingers86, two adjacent each end disposed on opposite sides of the work table and projecting towardseach other. Means are provided for swingingrthe fingers backwardly with respect to the directions of movement of the work table when the latter reaches theiextremity of its movement in either direction. These means are carried by the frame 1 and consist of the L-shaped arms 89 and 90 which are attached to the frame so that one leg of each lies in a horizontal plane with the other depending in a vertical plane. The fingers 86 may pass under the horizontal portions of these arms but are engaged b the depending or vertical portions and i the table be advanced to one end of the frame, the fingers 86 at the forward end of the table will be engaged by' the depending portions of the arms 89 will pass down between the bars 74 and to the left, as viewed in under the clamp thereof.

As the work table moves toward t e left the paper is drawn r ofi the supply roll by the moving table through the instrumentality of its clamping levers and fingers 86 which e go between the two layers of the fold. en

These fingers will therefore be-moved to a position where they may engage behind that art of the paper passing between the bars 4 down tothe work table. havmg reached the extremity of its movement in-the left hand direction and started .on its return. movement+that -is,' when it' starts its reverse movement which right handedly as viewed in Fig. 2all four fingers will be moved away from the arms which they previously engaged and will be caused bytheir attendant springs to assume their normal positions, the fingers at the right hand end of the work table swinging back to a transverse position on top of the fold which they previously engaged and the fingers atthe right hand end of the work table passing in behind at portion of the paper passing down between the bars 74 to the work table. The fingers on the right hand end of the table will therefore engage the palpercand as the table advances in a right anddirection will create a pull upon the paper and form another fold.

the table advances to its extreme right hand position, as above described, the 11fting arm 80 on the right hand bar74 will engage the extension 81 of the pin 76 of the right hand clamping members. These clamping members will therefore be raised from contact with their attendant block 7 9 and the fold bein formed by the fingers on the right hand of t e table as the latter starts backward'will be laid upon the block. After the table has advanced. far enough in its return movement to release the extension 81 from the lifting arm, the spring 79 will draw the clamping mmbers down upon the fold The table and it will be held in place thereon until the table reaches theend of its right hand movement, when the same cycle of operations will be repeated for the forming of a new fold when the table starts forward again a left hand direction.

To provide for the convenient forming of the supply roller 70, the main frame 1 isprovided with a top plate 91 to whose edge there ishingedly attached a swinging leaf 92. This swinging leaf may be turned upward, when not in use, as indicated in Fig. 1 of the drawings, but during the o eration of the machine it is swung outward y to lie in the same plane as the top plate 91 and in order that it may be maintained in this plane, there is provided a swinging brace member 93 which is hingedly attached to the frame -1 adjacent the bottom of the latter. This brace member at its upper edge engages Ill ' At the outer edge of the swin a transversely disposed batten 94 mounted on the under face of the swinging leaf 92. g leaf and on the top. faceof the latter t ere are carried two upstanding su ports 95, reset from their upperedge, as in icated at 96, to permit a bar 97 being held by the supports. Ob-

viousl this bar may be'readily removed or place in position on the supports and its purpose is to hold the usual roll of 'wall pa er, such as that indicated by 98. The ro 97 is'inserted through the roll of paper and then laced upon the supports. The pa .r is t ereu on transferred from this r0 1 98 to the r01 70, or if the roll 98 be the initial roll, it is transferred directly to the rod 69 it being wound around the latter and o the rod 97. When one roll 98 has thus been wound around the rod 69 the beginning of this roll matches with the end of the roll previously wound around the rod 69. To provide for securing the two rolls together when matched in this manner, the roll 99 of sealing tape is provided, this seal-- ing tape being wound in a roll with its adhesive face outward. Thisroll of tape 99 is carried on a ool 100 which in turn is carried by a. smal shaft 101 rotatably mounted in depending bearing supports 102 which are attached to theunder face of the swinging leaf 92. The tape, therefore, may be drawn off the roll 99 and across the top face of the leaf 92. The two matched ends of the two rolls being connected are thereupon laid down upon the tape and the paper moistened, this operation causing the tape to adhere the two connected ends for the pur pose of holding them together. When this as been accomplished the second roll may be wound ofi the roll 97, whereupon a third roll is wound upon the 'roll 97 and the previous operation continued until a suppl roll, such as the suppl roll 70, is obtaine this supply roll by t e operation cited above being composed of a number of the usuai rolls such as the M1198.

Paper from the roll 70 is fed between the the distributin roll and the drying roll the paper passes etween the trimming rolls 59 and 60 whose knives 61 serve to trim the selvage edge therefrom. The a er is then passed on to the table on whic it is folded in the manner before described.

Obviously the means for operatively connecting the sprockets 28 and 26 provides for operatin the table independently or the feed an trimming rolls independently of the table. All that is necessary to accomplish this is to withdraw the pin. '30 froin the eye formed for it in the sprocket 26. The crank 29 will then, when turned, rotate only the feed and trimming roll. Thus the paper ma be initially brought to the work:

table wit out the latter being reciprocatcd during such operation. If it is necessary to move the work table without moving the feed and trimming rolls, this can be accomplished by the simple turning of the crank 24. When the pin. 30 is engaged with its eye or socket 32 formed in the the crank 29 serves to move all of t e parts of the device.
