PAPER-BOX MACHIN E.
SPECIFICATION forming part of Letters Patent No. 507,931, dated October 31, 1893.
A Application filed December 15, 1892- Serial No. 455,286- (No model.)
To all whom it may concern-.-
Be it known that I, SAMUEL R. ROBINSON, of Antrim, county of Hillsborough, State of New Hampshire, have invented an Improvement in Paper-Box Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.
This invention relates to paper box machines, and more particularly to that class of machines wherein the box to be covered is placed upon a former, and a covering strip of paper previously supplied upon one side with paste, is applied to the exterior of the box upon the former, and this invention has for its object the production of a feeding and cutting devicefor the paper strip, to feed the same forward beyond and to free it from the cutting mechanism, so that it can be grasped by the operator without placing the hands wlthin range ofthe blades, and applied to the box on theformer.
My invention consists in a paper-box machine containing the following instrumentalities,viz :A former, paper cutting mechanism, and feeding devices including a table movable vertically and horizontally and upon which the paper rests, to grip a strip of paper near its leading end pull away and separate it from the fixed cutting member, and thereafter project said leading end forward between and beyond the open cutter members to be readily grasped by the operator and applied to the box on the former, substantially as will be described.
Other features of my invention will be here lnafter described and particularly pointed out in the claims.
Figure l of the drawings represents a sufficient portion of a machine for covering boxes, and partially broken away, to enable the same to be understood, with my invention applied thereto. Fig. 2 isan enlarged front elevation of a portion thereof. Fig. 3 is a greatly onlarged sectional view taken on the line 00 00, Fig. 2. Fig. 4 is a modification to be described. Fig. 5 is a view showing the feeding mechanism in its advanced position, with {She paper passed between the cutting memers.
The table A, standards A, the roll of paper B, trough O to contain paste or glue, or any adhesive substance, the roller D having a portion of its periphery immersed in the contents of said trough, and guide-rolls 1, 2, are and may be of any usual or suitable construction.
As shown in Fig. 1, one end of the table is provided with a suitable bracket a to support the rotatable former 0., upon which the box blank is placed preparatory to covering the same, as is usual in such apparatus.
As herein shown, the strip of paper 19, coated upon one side with the paste, passes from the trough O to the former a, and at proper intervals the said web is severed between the blades 0, d, of the hereinafter described cutting apparatus,-best shown in Figs. 2 and 3.
The rigid frame 6, attached to the standard A, has at one end thereof suitable bearings f,f, for a rod f, to which is secured a block or carrier g having attached thereto a movable blade d, a spiralor other suitable spring it connected at one end to the lower extremity of said rod f and at its other end to the frame e or to some fixed part of the framework, serving to lift the rod and blade.
The fixed blade 0 is rigidly attached to the frame 6 by screws m,m, and at the end nearest the rod f, a guide 0 is secured to the frame, the said guide acting as a bearing for the inner end of the movable blade in its reciprocations, the plane of the blades being transverse to the feed of the covering strip b.
The outer end of the movable blade (1 islated, tightening of the screws pressing the ends of the spring down upon the inclined upper face of the washer, the spring in turn forcing the blade (1 yieldingly against the fixed blade 0, and acting as a guide.
A suitable treadle t is connected to the rod f by a pivoted link t, so that when the treadle is depressed the rod f carrying the blade at will be moved in a downward direction and the edge of the movable blade inclined with relation to the fixed blade, will be drawn down over the edge of the fixed blade 0 ICO with a shearing cut. The said blades are thus arranged one with relation to the other that contact between them is at substantially a single point, the said point of contact moving from the inner toward the outer end of the blade d as it is moved downwardly, and the spring it always keeps the blades pressed together at such point of contact with the proper degree of force.
The strip of paper is drawn forward by the operator, from time to time, by grasping the leading end of the strip and drawing off a length suificient to cover the perimeter of the box blank, and also to separate the end of the strip from the fixed blade, to which it adheres by reason of the adhesive substance on its under side, necessitating the frequent passage of the hands between the cutting blades, in order to get at the strip and to obviate this, and thereby the consequent danger of injury to the operator by premature or accidental closing of the blades, I have herein showna feeding device to grip the strip near its leading end and project it forward beyond the cutting members to be readily grasped by the operator, and the proper length drawn off previous to severing it, without danger to the hand, the fixed blade being guarded, as will be described, while the strip is drawn 0d.
To parallel rockshafts n, n, supported in cars at" secured to the frame 6, I have herein shown attached arms n, n, pivoted respectively todepending ears or lugs 12 n, of a strip support, herein shown as a narrow platform ortablen, in its normal position see Fig.1, at the rear of and substantially level withthe edge of the fixed blade 0, the arms it being pivotally attached to the rock-shaft n. The ears or lugs n are extended above thetable, see Figs. 1 and 3, and are connected by a rod 0 upon which a gripping frame is pivoted, the latter consisting of sides 0 connected by rods 0 0 and a link 0 is pivoted at its ends to the rod 0 and a lever 0 which lever is socured to the rock-shaft 'n, and is provided with a hand piece 0, extended in front of the frame 6, as shown in Figs. 1 and 3. I have herein shown grippers 0 as supported on the rod 0 and longitudinally adjustable thereon by suitable set screws, as best shown in Fig. 2.
The arms n, n, and ears or lugs n a, form toggles to support the table n at each end, and the toggles are normally bent as in Fig. 1, the gripping frame being lifted from the table'by the spring 3, secured to the lug 8' depending from and forming a stop to limit the fall of the table.
In operation, the parts being in the position shown in Fig. 1, the operator will depress the hand-piece 0 and lift the inner end of the lever 0 thereby, through the link 0 tipping the gripping frame and bringing the grippers down upon the strip near its leading end,
which is firmly held between the grippers and the table top and extending the spring 5'. Conis completed the lip 0 attached to or forming a part of the front edge of the table, and supporting the end of the strip, will have been carried with the strip above and in front of the top of the blade 0, as shown in Fig. 5, pulling away and separating the strip from the blade 0 and projecting the end of the strip forward and beyond the blade so that the operator can grasp the same and draw the required length from the roll B, the pressure on the hand piece having been removed, the front edge of the table, and the projecting lip 0 at the same time forming aguard over the edge of the fixed blade, and preventing the hand of the operator coming in contact therewith. hen the pressure is removed the grippers first rise from and release the strip, the tension of the spring s drawing the lower ends of the sides 0' in toward the table, and then the table falls back into its normal position, the sides 0 then assuming the position shown in Fig. 3. The treadle t is then depressed, and the strip severed, thus leaving both hands free to manipulate the box and its covering,
and keeping them out of range of theblad es. When' the strip is stiff cardboard or paperit can be pushed beyond the fixed blade and loosened therefrom by a grippin g feed which moves in a horizontal plane toward the said blade, but when thin, pliable paper is used its inherent flexibility is increased by the addition of the adhesive, and were a gripping feed used therewith which had a'horizontal' Imovement only, and toward the blade, the ileading end of thestri'p could not be'separated from the fixed blade and instead the part of the strip between it and thefeed device would buckleor bend-and the operator would have to' grasp the strip by passing the hand between the blades. By giving the supporting table and gripping frame a movement upward and then forward the leading end of the strip is pulled away and separated from the fixed blade and then projected between and beyond the cutting blades, asdeScribed, so that the softest paper can'beused as readily as the stiffest.
In Fig. 4 I have shown a modification of the cutting mechanism whereinthespring at the outer end of the blade is dispensed with, the movable blade being pressed against the fixed blade by the torsional action of the coiled spring 71?, one end of which is rigidly attached to the rod f, and the other end to a fixed part of the frame. This form of spring is best adapted to short blades and I have shown the frame as provided with a guide a, as hereinbefore described. The pressure is regulated by twisting thespring more or less. The edges of the blades are oppositely beveled as shown in Figs. 2 and 3, said edges being perfectly straight from one to the other end,
whereby grindingis much simplified andthe time and skill required to properly grind the blades when dull is greatly reduced.
If desired, the lever 0, may be elevated by means of a link 0 see Fig. 1, connected to an elevating treadle of usual construction.-
A weight 0 carried by an arm rigidly secured to the rock-shaft n tends to counterbalance the weight of the table and gripping frame. v
While I have herein shown my invention as applied to a paper box making apparatus, yet I do not desire to confine myself to such use, as the same is applicable to any machine or apparatuswhere paper or other material in roll or web form is used, nor do I wish to confine myself to the specific construction and arrangement of parts as herein shown and described, as the same may be'varied with out departing from the spirit of my invention. 'It is evident that the cutting mechanism may be used without the-feeding devices, and that it is well adapted to cut or trim super-imposed sheets of paper, the pile being fed forward from a bench or table at substantially the level of the fixed blade, said bench or table being provided with the usual gages common in paper cutting machines.
