INVENTOR Harry Pierce Patented Oct. 13, 1936 CUTTING AND GUMMING MACHINE Harry Pierce, Brooklyn, N. Y., assignor to The Pilgrim Laundry, 1110., Brooklyn, N. Y., a corporation of New York Application November '7, 1935, Serial No. 48,657
This invention has for its principal object the production of a simple, effective and compact machine adapted to cut a sheet of material of any desired length and to simultaneously apply an adhesive along an edge thereof whereby opposite edges may be glued together, to facilitate the packaging of goods.
The invention is particularly adapted tothe application for use in laundries for wrapping .small articles of launderedv goods, such as handkerchiefs, which have been folded and ironed. I prefer to use a cellulose material as the matermial for the wrapping, but other materials, such as paper, may also be employed as will be obvious.
The machine of the invention may be conveniently detachably fastened to any small table or other support with the goods to be packaged placed by the operator readily accessible.
The invention preferably includes mechanism supplied with a cutter and an adhesive-applying device both set into action and operating by pressure applied against a lever, preferably a foot-lever, such mechanism being automatical- 1y returned to its initial and inoperative position upon the release of pressure against said lever.
Other and further objects and advantages of the invention will appear from the accompanying description, the invention consisting in the novel apparatus and parts thereof hereinafter more particularly described and then specified in the claims.
In the accompanying drawings illustrating a practical embodiment of the invention:
Fig. 2 is a side elevation thereof.
Fig. 3 isa plan view of a part of this device, certain elements being omitted.
Fig. 4 is afront elevation of a part of the, machine showing the cutter and adjacent mechanism.
Fig. 5 is a perspective view of the adhesive applicator and adjacent mechanism.
Fig. 6 is a front elevation (partly in section) of the adhesive applicator.
Referring in detail to the several figures of the drawings;
The top or horizontal plate of a supporting table is indicated at l and is supplied with vertically extending legs .2 secured thereto in any desirable manner. The angled side walls of the frame of the machine are indicated at 3 and these are secured together in spaced relation by Fig. 1 is a front elevation of my improved. ma- 1 a plurality of bolts 4 carrying suitable holding nuts 5, said side walls 3 tachably fastened to the screws as shown. Mount being also suitably detop 0f the table as by ed in the side walls 3 is a roller 6 on which is wound a roll of cellulose material or paper-like material 1 which passes over and under upper and lower rollers 8 and 9 respectively and then beneath a feltfaced guide l0 resting on a plate ll connecting and secured to the side walls 3 as by screws as shown. The felt-faced portion of the guide is held to the guide proper by headed screws [0. The plate II is provided with pins l2 extendingv through holes in the guide It! for properly positioning said guide. The
purposev of said guide is for retaining the cellulose material in a smooth unwrinkled. condition and for delivery to the operator in that condition.
A braking device comprises a rotatable rod [3 mounted on arms 14 which are pivoted to the side walls 3, said rod carrying curved braking elements l5, preferably of leather or some other pliant, soft material.
These: braking elements have a configuration conforming to the configuration of the roll of cellulose material 1 and act thereon by gravity to-hold the material more or less taut and without t unwinding thereof.
caring and to prevent A plate [6 of somewhat narrow width extends across the machine and is secured to the side walls 3 in any desirable manner and anterior to plate II. It is provided with a front shearing bevelled edge I! and with a rear friction-eliminating bead l8 over which the cellulose material 1 passes. Standards l9 and I9 are secured to the angleportions of the side walls 3 and are connected together by a track bar plate 2| lying in the 20 and by a horizontal same plane as plate it but spaced therefrom and forming with the bevelled edge I! of plate l6 a slot 22. The outer or forward edge of plate l6 which forms the inner or rear wall of this slot is undercut to produce the beveled guiding edge I! which in effect may serve as a stationary cutter or knife.
Plate 2| is also provided with a groove 23 for a purpose to be presently described. Secured to standard I9 is a fiat guide strip 24 slotted at 25 and provided 26 beneath Standards which the cellulose material passes.
l9 and I9 are also provided with lower and upper brackets 21 and 2l' able pulleys 28 are journ ards I9 and 19 also each respectively in which suitalled. The said standhas secured thereto adhesive applicator raising bars'29 having inner cam edges 30.
Secured to a side of the table by brackets 3| is a tube 32 receiving a counterweight 33 slidable therein and to which a chain 34 is attached. Said chain passes through brackets 2'1 and 21' and over pulleys 28 and is fastened to the end of a lever 35. Said lever 35 is pivoted as at 35 to a bracket 35 secured to the under side of plate I and is also pivoted to a forked lever 36, the lower end of which is in turn pivotally connected to a rod carried by a foot treadle 31 having an extension 38 which is pivotally connected to a rod 39 journalled in opposed vertical legs 2. A spring 40 is fastened to a stud on standard l9 and to lever 35 adjacent its free end. Obviously the action of spring 40 supplemented by the action of counterweight tends to swing lever 35 on pivot 35' in a clockwise direction to retain the foot treadle 3'! in raised or elevated position.
4| indicates a block or carriage slidably receiving track bar 20 and it carries an arm 42 fastened thereto by headed screw 43, said arm being fastened to a sleeve 44 slotted as at 45. Said sleeve receives an adhesive applicator tube 46 having a valve stem 41 extending therethrough and through a head 48 of the tube, the stem carrying a valve member 49 adjacent its lower end and adapted to seat against a suitable valve seat to close an orifice or opening in the end of the tube which is positioned so as to be in alignment with the groove 23 in plate 2|. The tube 46 contains mucilage or other suitable adhesive which flows through the orifice in its end and just referred to when the valve member 49 is raised from its valve seat. Tube 46 is removable from sleeve 44 and movable vertically therein and it carries a pin 58 normally received by a slot 45 with which the sleeve is provided. The tube is also provided with an opening 52 and guiding trough 53 for filling purposes.
A second track bar is indicated at 54. This bar is generally inclined downwardly toward the left as illustrated and it is provided with rounded ends which are journalled in inclined standards 55 and 55' so that it is capable of partial rotation or lateral rocking movements in its bearings. Said track bar 54' slidably receives a carriage block 56 to which a cutting knife or blade 51 is fastened and which enters within the slot 22. A spring 58 is secured to the right-hand rounded end of bar 54 and to the lower end of standard 55' or other fixed part and tends by its action to 55rotate or rock the bar laterally in a direction whereby the knife or blade is held yieldingly pressed in engagement with the bevelled edge ll of plate l6 whereby a shearing cutting on the material to be cut may be obtained between the knife and said bevelled edge along a definite cutting line at all times. By this means the cutter blade 5'! is always guided in its cutting action against the rigid surface formed by the guiding edge so as to cut along'a line where the material is firmly supported during such cutting action and where the cutting action is assisted and facilitated by the knife like edge IT. This guiding action and engagement of blade 51 with the guiding edge I! is maintained by the action of spring 58 on track v 54 notwithstanding any possible looseness of parts which may occur from wear and which otherwise would allow the blade 5'! to move out of contact with the edge I! and to have lateral play in slot 22. Certain sheet materials, such as cellulose materials, tear with difiiculty and therefore do not 'respond readily to usual shearing cuts. This diificulty is overcome by the construction described whereby the cutter 5'! is prevented from having any wobbling movement and is caused to out along the line of the edge ll of the plate I 6 against which the material is firmly supported. Said carriage block 56 has an upwardly extending bar 59 fastened thereto and to which chain 34 is attached and said bar 59 extends intermediate pins 60 on block 4| to provide a loose connection between carriage blocks 4| and 56 so that movement of one will effect a movement of the other on their respective tracks.
A clamp having a vertically extending leg 6| and a horizontally extending clamping portion provided with a curved or hooked end 62 is pivoted to a lug 63 fastened to inclined standard 55'. A pin 64 is fastened to leg 6| and extends through a slot 64' in standard 55 and a spring 65 is fastened to the end of said pin and to the standard and tends by its action to pull the end of the pin upwardly and rock the clamp on its pivot in a counter-clockwise direction and into clamping position.
The operation of the device is as follows:
The parts are normally in the position shown in Fig. 1 because of the action of spring 40 and counterweight 33. When in this position, pin 50 on adhesive applicator tube 46 lies on the cam edge 30 of the right-hand bar 29 and has raised the tube 46 in its sleeve 44 thereby permitting the valve 49 to close the outlet in said tube by the action of gravity. The clamp 62 has also been raised into unclamping position by pressure of the carriage block 56 against the vertical leg 6| of said clamp and against the action of spring 65. The cellulose or other material I which is wound on roller 6 has been passed over roller 8, under roller 9, beneath guide Ill, over bead I8 and beneath the guiding fingers 26 of guide strip 24. The wrapping material is then pulled forwardly a sufllcient and desired extent by the operator and the foot pedal 21 is depressed. The clamp 62 is then immediately clamped against the material in an obvious manner by the action of spring 65 to hold the material firmly for the cutting or shearing operation. Depression of the pedal also forces the carriage block 56 to the left on its track or bar 54 thereby forcing the carriage block 4| to the left on its track bar 20 due to the connection between the parts. Meanwhile the action of spring 58 keeps the blade or cutter 51 in engagement with the bevelled knife edge H of slot 22 for coaction therewith to effect a shearing action of the blade or cutter across the machine and through the cellulose or other material. By this coaction between the movable knife blade 51 and the stationary knife edge I! a clean cut through even very thin sheet material may be effected without drawing or wrinkling the material or producing a ragged edge. As the carriage blocks begin their movement to the left the cutter not only begins its shearing action, but the pin 50 also then rides down the cam surface 30 of the right hand bar 29 and. finally rests at the bottom of the slot 45 in the sleeve 44. This permits the end of the valve stem 41 of the adhesive applicatorto press against the cellulose material and open the valve to permit of the spread of a line of adhesive on the cellulose material as shown in Fig. 5. When the carriage blocks reach the end of their travel at the left side of the machine, pin 50 engages and rides on cam surface 30 on the left-hand bar 29 to again close valve 49 in the applicator. It will thus be seen that the sheet of material is simultaneously gummed and amazes sheared by the application of pressure against foot pedal 31. When pressure :on the foot pedal is released, the carriage blocks ride back to their initial positions on their respective tracks by the action of spring 40 and counter-weight 33. Upon the return movement of the carriage blocks, the adhesive applicator tube 46 again falls within -its sleeve 4'4 but the valve 49 remains closed-there being no pressure exer'tedaga'inst the end of the valve stem 41 as it rides within the slot 23. The goods to be packaged are then placed on the cut sheet :of material and the sgummededge is applied to the opposite edgeto secure the edges together after which'the free ends 0f the package .may the folded up and over or both to suit theoperatorts convenience.
It will be understood that modifications :may :be made and still be withinthe invention as set .forth in the appended claims.
