To all whom t may concern:

Be it known that LEDWARD STEPHEN, a subject of the King of Great Britain and Ireland, :and resident oflO' Daisy Bank Road, Victoria Park, Manchester, in the county of Lancaster, England', have inventedv certain new and useful Improved l\/Ieans for Detaching and Delivering Lengths of Peper Or thelke from `2i R011, ,OVi/hh th 1.0 following is a specification. i invention Irelatesto means for zdetaching and deliveringflengths lOf palper, cai'itboard and the likej'froim 'a'roll andfniore particularly to adevice for ,detachingtick ets froma roll which is perforated to faciliwie the separation @f the tickets, the @bien being to provide a simpele"andefficientar-` rangement of mechanism which is.reliable'in4 its'action and readily operated.

In accordance with invention, the device comprises two pairs of coi-operating rollers, the one ypair serving to feed the paper or the like to the other pair, and the latter pair (which has a greater peripheral speed than the former) serving to detach the individual lengths of paperor the like at the perforations. The two pairs of rollers are rotated positively by a hand or foot lever or other convenient means oper-V ating by means of pawl and ratchet mech anism which allows of the operation of the rollers by the levers when the latter is movingin one direction only.

The mechanism is enclosed'within a suitable box or casing having an inlet slot through which the paper from the roll is fed to the feeding pairv of rollers and a discharge shoot through which the individual tickets or lengths of paper are delivered.V

40 The operating handle projects through a slot in the boxor casing, the length of the slot being such that when the lever hasbeen moved from top to bottom thereof, one ticket r is delivered from the machine. Or the han- 4" dle may be secured upon a spindle projecting through the casing. A carrier plate or guide is arranged between the two pairs of rollers, the distance between the nips of said rollers may be equal to or greater thany the length of each individual ticket.

With the arrangement before. described whenl the operating lever is actuated, the feeding rollers deliver a ticket to the nip of the separating rollers which, by reason of their greater peripheral speed, exert a drawingl action on the ticket, separating it from the what' theL perra-ations.

The rollers may 'be made or covered with any L'suitable n'iaterial.'A -Vhen it is'ld'esire'd to utilize my yimproved mechanism for separating and zdeseparating orfdelivering'rollers' sothat'a portion only ofjthe peripheral surface of jeachJrolle-i-"can engage the-`t1cket the re- Iif the periphery beingcut 'awaytor set back. VVithf'this arrangement, the' "feedf agallas deliver rhefecka'so'tm are raidperforationisI just 1kbeyond the nip ofj the separating rollersfwhen theI actiifeprtions of `the Iperipheries obfjsaid rollers engage the 'ticket and detach it from the'roll.l "By this means', 'I prevent the ticket-being torni-at f the midperforations.

Referring to the two accompanying sheets Y of explanatory drawings 2,-

Figure l is a front elevation, Figure 2 a side elevation and Figure 3 a back elevation of a ticket separating and delivering machine made in accordance with my invention. A Figure 4 is a side elevation and Figure 5 a front elevation sho-wing a modified arrangement of machine.

`The same reference letters in the differ-y ent views indicate the same or similar parts.

The tickets in roll form are carried by the spindle a vbetween the conical collars b, c thereon. The end of'f'the roll is threaded through the slotd in the casing e and between the pairsV of rollers f andvg. The spindles of said rollers carry spur wheels 7L, z' which are rotated either directly by the large wheel j or through carrier pinionslc as shown. A ratchet wheel m is secured upon the spindle carrying the large wheel j and is rotated by a pawl n upon the handle o, the latter being lowered when it is desired to deliver a ticket. A spring p returns the handle to its uppermost position.

A channel or guide' is provided for the tickets passing betweenthe rollers f and (y. The tickets delivered from the rollers g pass down and rest in the end of the chute r.

A door s is provided on the casing topermit of ready access to the mechanism.

ln service, the tickets are fed by the rollers fito the nip ofthe separating rollers g which roll at the perforations.

In the arrangement shown at Figures 4 and 5, the. separating rollers g are made with a port-ion of their peripheries recessed orcut away as shown. The rollers f are rotated from the spur wheel jl but the rollers g which are geared together are rotated from the handle o by a rack fw. The stroke of the handle o is limited by the stop so that any desired length of ticket may be passed `through the rollers and g before the latter rollers nip it and separate it from the ticket roll. This arrangement may be particularly7 advantageous for use with tickets having mid-perforations. The rollers g then nip the ticket between the perforations, where. separation is to be effected, and the mid-perforations.

I do not limit myself to the yparticular means shown for rotating the separating rollers g as these may` be operated by any known means which allow of the variation 0f the time at which they nip the tickets from the rollers f.

I elaima-f n l. Means for =detaching and delivering lengths of paper or the like from a roll,

comprising two pairs of rollers, means for rotating the. same with differential surface speeds, one pair of the rollers drawing the roll and the other pair separating the individual lengths and delivering the same, as set forth.

2. Means as claimed in claim l, wherein an operating handle is provided and is operably associated with the pairs of rollers and means for returning the handle to its initial position, as set forth.

3. `Means as claimed in claim l, wherein a guide is provided between the respective pairs of rollers and al delivery chute and holder operatively associated with the means, as set forth. y

4l. Means as claimed in claim l, wherein the operating and delivery rollers are formed with recessed peripheral portions, as set forth.

5. Means as claimed in claim l, wherein a manually operable handle is provided, gearing associated with both pairs of rollers, pawl and ratchet mechanism operably arranged between the gearing and handle, and meansk for returning the handle to its initial -position as set forth.
