1 Claim.

Our invention relates to a combined feeder and cutter for roll paper and the principal object of our invention is, to provide a relatively simple, practical and inexpensive extension paper cutter f 5, that may be conveniently employed for feeding the free end of a roll of paper to a point within easy reach of the operator in cases where, due to the construction of the counter or show case, it is necessary to locatethe roll of paper upon or 10, near the floor. Y

The invention herein disclosed is an improvement on the constructions forming the subject matter of co-pending patent applications filed by James W. McClintock as follows: Roll paper outlter, sled March 22nd, 192s, seria No'. 263,637, patented March 24, 1931 as Patent No. 1,797,432; Roll Paper Holder, filed January 16th, 1929, Serial No. 332,990, patented Jan. 5, 1932 as Patent No. 1,840,120; Roll Paper Cutter, filed April 22nd,

20, 1929, Serial No. 357,113, patented June 28, 1932 as Patent No. 1,865,399.

Further objects of our invention are, to generally improve upon and simplify the existing forms of extension roll paper feeders and cutters and particularly the constructions disclosed in the above mentioned co-pending patent applications and further, to provide a device of the character referred to that is very compact so that it occupies comparatively littley space when positioned for use on a show case, counter or the like and further, to provide an extension roll paper feeder and cutter having convenient and easily manipulated means for effecting a positive feed for the end of the web of paper that passes V through the device.

` With the foregoing and other objects in view,

our invention consists in certain novel features of construction and arrangement of parts that will hereinafter be more fully described and claimed and illustrated in the accompanying drawings, in which:

Fig. 1 is an end elevational view of an extension roll paper feeder and cutter constructed in accordance with our invention.

Fig. 2 is a front elevational View of the combined feeder and cutter, A

Fig. 3 is a vertical section taken approximately on the line 3 3 of Fig. 2.

Fig. 4 is a vertical longitudinal section taken approximately on the line 4 4 of Fig. 1.

Fig. 5 is a cross section taken approximately on the line 5 5 of Fig. 2.

Fig. 6 is an elevational view of the extension roll paper feeder and cutter positioned for use on the rear of `a counter or show case and with the ing member, for instance, the rear wall of a show case or counter and which plates serve as supports for the operating parts of the device. The

lower portions of these end plates are connected by a substantially Z plate or bar 11, the ends thereof being secured in any suitable manner to ears or flanges 12 that project inwardly from the lower portions of the end plates.

Formed integral withor fixed to the outwardly projecting portions of the end plates 10 are inwardly projecting tubular members 13 and extending through these tubular members and arranged for rotation therein are short spindles 14 and secured to the inner ends of the latter are disc heads 15.

. Arranged between the end plates is a paper feeding roll 16, preferably a metal tube and this tube is secured to the heads 15 in any suitable manner, preferably by indented portions 17 and thelwall of said roller and short indented portions project into notches 18 that are formed inl the heads.

The external surface of roller 16 is roughened or coated with rubber or rubber composition in order to produce a frictional surface.

At one end of the roller the `wall thereof is provided with a series of ratchet teeth 19 and adapted to engage these teeth is a detend 20 that is pivoted on the adjacent end plate 10.

Journaled in an axial bore 21, that is formed in each spindle 14, is a pin or shaft 22 and secured to the outer end thereof and positioned beyond the outwardly projecting portion of the end plate 10 is a small drum 23.

Secured to the periphery of this drum is one end of a ribbon spring 24, the opposite end thereof being secured to a manually operable frame, as will be hereinafter more fully described.

Fixed on the outer end of spindle 14, within the drum 23, is a ratchet wheel 26 that is engaged by a spring pressed pawl 27 and the latter being pivotally mounted on the drum.

Formed integral with the circumferential wall of drum V23 is a finger 28 that projects through an arcuate slot 29 in the outwardly projecting portion of the end plate 10 and engaging the inner end of this linger is one end of a coiLspring 30,

which latter surrounds the tubular member 13 and the opposite end of said spring being secured to the inner end of said tubular member.

The manually operable frame or handle that is utilized for imparting rotary movement to the paper feeding roller 1 6 comprises a pair of end plates 31 that occupy positions adjacent to and parallel with the outwardly projecting portions of the end plates 10 and these plates 31 are provided with notches 32 for the accommodation of the drums 23.

The lower inner ends of plates 31 are secured to the ends of a shaft 33 and the latter is journaled in ears 34 that project downwardly from the rear portions of plates 10.

Projecting outwardly and upwardly from the upper forward portions of plates 3,1 are short arms 35 and secured thereto are the ends of a rod 36 that functions as a handle and which is manually engaged when the paper feeding operation takes place.

The outer ends of the ribbon springs 24 that pass around the drums 23 are connected to pins 25 that project inwardly from the outer portions of plates 3.1 (see Fig. 3).

Formed in the outwardly projecting portions of the plates 10 and concentric with the axis of rod or shaft 33` are arcuate slots 37 and projecting therethrough are. short fingers 38 that are formed integral with the lower rear portions of the, plates 3 1.

The construction just described serves to limit the outward swinging movement of the frame comprising plates 31 and rod 36.

Arranged between the outwardly projecting portions of the end plates 10 is a cover plate 39 that is shaped so as to` cover the front and top of the. feed roller and the lower portion of the front wall of this cover plate is extended outwardly at a slight angle relative to a vertical plate and the lower edge of this inclined portion is sharpened in order to form a paper tearing edge 40. The lower portion of this cover plate is suitably hinged, preferably by means of rivets 41 to the lower front portions of the outwardly projecting members of end plates 10.

Secured on the inner face of cover plate 39 are flat springs 42, the free ends of which bear with yielding pressure against the surface of the paper v' that passes over the feeding roller 16 (see Fig. 5).

Secured to the upper rear portion of cover plate 39 and projecting outwardly therefrom directly over the rear portions of endplates 10 are fingers 43 which may be engaged to swing the cover plate outwardly for the purpose of threading or arranging the end of the web of paper over the feeding rollerA 16.

In order to thread the webof paper through the combined feeder and cutter, rod 36 is engaged and swung outwardly and downwardly to its limit of movement and cover 39 is now swung outwardly and downwardly so as to rest on rod 36, thereby holding the latter andthe end plates 31 in their outwardly shifted positions. When the parts are thus/shifted the feeding frame occupies the position as shown by solid lines in Fig. 6 and the cover plate occupies the position shown by dotted linesof said figure.

The web of paper. is now drawn upwardly behind the Z bar 114 and to the rear of the feeding roller 16 and the end of the web of paper is brought over the roller and downwardly in frontv of the same.

Cover plate 39 and the frame comprisingharndle l 36 and end plates 31 are now restored to their normal positions and the device is ready for use.

When a portion of paper is torn from the web that passes through the device the end of the paper occupies a position immediately behind the tearing edge 46 that is formed on the lower edge of the wall of the cover and in order to feed outward and downward a sufficient amount of paper would be grasped between the thumb and ngers so` that the desired portion of paper may be un wound from the roll, the operator engages handle 36 and swings the f same outwardly and downwardly to its limit of movement, as shown by solid lines in Fig. 6. v

As this movement takes place the ribbon springs 24 that are connected to end plates 31 impart rotary motion to the drums 23 and through pawls 27 and ratchet wheels 26, this rotary motion is imparted to. spindles 14 and which latter are connected through heads 15 to feed roller 16.

As the feed roller is thus positively rotated and as the web of paper is in engagement with the. frictional surface of said roller, said web ofl paper will be movedso that its, end portion will be prof. j ected a short distance below the tearing edge 40.

As the feeding frame comprising handle 36. and end plates 3.1 is actuated as just. described springs 30 which are connected at their outer ends to thedrums 23, will be partially wound, thereby storing tension therein and upon the release of the feedingv frame the tension of said spring-s. 30: will reversely rotate the drums 23, thereby rewinding the ribbon springs 24 thereon and returning the feed-. ing frame to its, normaly position. During this operation the points ofthe pawls 2'7 ride over the ratchet teeth` 26. During this return of thefeedfA ing frame andV the drums to their normal posi. tions, the feeding roller is. held against reverse ro tation by` detent 20 that` engages the` teeth 19; on, the end of the feeding roller.

After a short portion of the end of the; weby of paper has been fed downwardly and outwardly below the cutting edge 40, as just described, the. operator engages theprojecting portionA of the paper u with the thumb and: ngers and exerts suflicient 126 pull'to. unwind a portion of thev paper from the roller and which paper passes overl roller-f 16, thereby rotating the same so as to forma rollingsupport for that portion of the paper that is withdrawn and during this rotation ofthe roller the ratchet teeth 19 ride past the point of detent 20- andthe teeth ofratchetwheel 26 ride past detent 27.

When the desired amount of paper has thus s been unwound from` the roll andfdrawn, through 130 the combined feeder and cutter the operator pulls the withdrawn portion ofthe paper upwardly with a quick movement'against' the cutting edge 40, thereby severing the web. of` paper on a straight transversely disposed line and the portion ofj paper thus out fromthewebis now used for wrapping purposes.

Any tendency of that portion of the enolA of thev web of paper between the roller and the cutting edge 40 to buckle or curl upwardly, within the`- housing is resistedby the flat springs42 that bear on that portion of the web of paper that overlies. the front side of the roller and thusk the end.v of the web of paper is retained in properv position for downwardmovement upon the successive operation of the feeding means.

Thus it.A will b e seen that Wevhave provided a combinedy paper feeder and cutter thatis rela-f. tively simple in construction, APositive in operation;V ma

its

1W i We claim as our invention:

In a roll paper feeder and cutter a housing comprising, a` pair of end plates, and a bottom plate having its ends rigidly connected to said end plates, a roller arranged for operation between said end. plates, a pivotally mounted frame comprising a pair of end plates that are positioned adjacent to and outside the first mentioned end plates and a rail connecting the upper front portions of the end plates of said pivotally mounted frame, ratchet and pawl connections between said frame and roller for rotating the latter in one direction, means for returning said frame to its normal position after its roller actuating movement, means for holding said roller against reverse rotary movement, and a cover for said roller, which cover is hinged vto the lower front portion of the first mentioned pair of end plates.
