- the base-plate is further provided with a pair of cutting-blades 12, arranged on divergent lines corresponding to the angles of the edges of the tongue, and these blades are slightly inclined, their rear edges being somewhat higher than the front edges, so as to act, in conjunction with the cutting edges, on the plate 2 to effect a shear cut.
- the base-plate is further provided with a pair of lugs or shoulders 14, arranged Aat the inner walls of the blades 12 and forming inclined supports for the tongue, so that the latter when cut will be immediately bent at an angle to the general plane of the base-plate and the sheets of paper or envelop thereon.
- the upper plate 2 is provided with a suitable opening having two inclined walls 15, arranged on lines corresponding to the angular planes of the tongue edges, and these walls serve as cutting' edges in connection with the blades 12.
- the forward end of the opening is approximately rectangular in form, and depending from its opposite parallel side walls are cutting knives or Iblades 16, that are adapted to cooperate with the cutting edges of the recess 9 to form the parallel slits in the paper.
- rlhe blades are preferably inclined, as shown, in order to form a shear cut; but the blades are so arranged that their cutting edges will but slightly pass below the upper surface of the base-plate, so that the undercut portions of the wallslO will be free and unobstructed and permit the sides of the tongues to pass thereinto.
- a longitudinally-disposed slide 19 On the top of the plate 2 is arranged a longitudinally-disposed slide 19, that is normally projected to a position slightly over the forward end of the opening by means of a compression-spring 20, suitable guides 21 being employed to maintain the slide in proper position.
- the rear end of the slide, or that portion which projects over the opening, is tapered and inclined in order to form a bendinganvil 22, on which the central portion of the tongue is bent in order that the side edges of the tongue may be brought nearer each other preliminary to their introduction through the parallel slits.
- the upper plate 2 is provided with a pair of guiding-pins 25 and 26, that extend through suitable slats formed in a tongue-folding slide 27, and the lower portion of the front end of said slideV is provided with a V-shaped groove or recess that in part coacts with the similarly-shaped anvil 22 to form the fold in the tongue.
- l The greatest depth of the recess is at the front end of the slide, and the upper wall ot' the recess from thence tapers gradually until it merges into the bottom line of the slide, so that there is formed a V- shaped slot of continuously-decreasing crosssectional area from the front toward the rear of the slide.

To (1J/, wim/n, t 771//1/3/ concern:
Be it known that I, SAMUEL l).RU'rH, a citizen ot' the United States, residing at Beatrice, in the county oi' Gage and State of Nebraska, have invented a new and useful Paper Cutting and Folding Machine, ot' which the following is a speciiication.
This invention relates to certain improvements in machines oi' that class employed for the formation oi' locking-tongues in sheets oit paper, envelops, and thelilte, to be employed fortsecuring the sheets or envelops without the use of clips, eyelets, or any oi' the similar fastening devices in ordinary use.
One of the principal objects ofthe invention is to construct a machine by means oi' which a paper tong'ue or tongues may be cut in the tolded edg'e of a number oi' sheets oi' paper or an envelop and bent over and its opposite edges engaged inholding-slits by a single movement of an operating-lever.
A further object of the invention is to provide a machine by which all oi the slits in the sheets may be cut at the same time and by which the tongue i'ormed by one pair of slits may be turned and then inserted in the remaining slits.
WV ith these and other objects in view, as will hereinafter appear more fully, the invention consists in the novel construction and arrangement of parts hereinafter described, illustrated in the accompanying drawings, and particularl y pointed out in the appended claims, it being understood that various changes in the i'orm, proportions, size, and minor details ot' the structure may made without departing from the spirit or sacriiicing any of 'the advantages ot' the invention.
ln the accompanying; drawings, Figure l is a longitudinal sectional elevation oi a paper cutting' and folding machine constructed in accordance with the invention. Fig'. 2 is a transverse sectional elevation of the same on the elevation on the line 5 5 of Fig. i- Fig'. 6 is a view illustrating a sheet or sheets of paper :t'olded at one corner and provided witha pair oiI parallel slits and a pair of divergent tongueforming slits. F 7 is a similar view showing the tongue folded over and its edges inserted through the parallel slits. Fig. 8 is a view corresponding' to Fig. l, illustrating a modiiication of the invention. Fig. 9 is a detail perspective view illustrating a further 'the several ligures ot the drawings.
The machine forming the subject of the present invention is designed i'or the forma# tion or' a locking-tongue in sheets or envelope and the bendingot the tongue and the insertion oi' its edges into a pair ot' parallel slits arranged adjacent to the tongue and disposed in such manner that the tongue will be retained in place and all of the sheets of paper or the envelop will be iirmly secured, thus dispensing' with the ordinary metallic clips or other securing devices ordinarily employed Afor a similar purpose.
1n order that the invention may be under stood better, reference is had lirst to Figs. (i and 7, which illustrate a number of superposed sheets oi' paper bent at one corner and provided with two divergent slits a a, forming' a tongue and a second pair of parallel Slits c.'
ln practicing the invention the slits are (irst cnt, and then the tongue Vi'ormed by the divergent slits is bent over on top of the paper and its opposite edgesinserted in the parallel slits, as shown in Fig. 7. This iorms a positive lock for the paper, and it may be utilized in securing together a number ot' sheets or may be employed for closing envelops, circulars, and other articles which are to be sent by mail at other than lirst-class rates.
The mechanism is mounted on a suitable IOO base 1, to the rear edge of which is pivoted a plate 2, that is normally maintained with its front edge slightly elevated above the top of the base-plate, this being accomplished by the employment of one or more springs or by forming the plate itself of spring' metal and riveting' or otherwise securing its rear edge to the base. From the opposite sides of the base rise standards 3, forming supports for a transversely-disposed bar f1. to which is secured an operating-lever 5, havinga suitable handle member 6 and provided with a pair of spaced depending arm 7, which bear against blocks 8, secured to or forming a part of the plate 2. Thisl lever serves as a means for operating all parts of the apparatus, and a single forward and downward movement is all that is necessary to accomplish the cutting of the several slits and the bending and insertion of the tongue in the parallel slits.
In the upper face of the base-place is a recess 9, approximately T-shaped in contour, the opposite side walls of the longitudinallyextended portion of the recess being' undercut, as illustrated at 10, in order to afford a space for the insertion of the edges of the tongue during the operation of inserting the latter through the parallel slits. These walls further form cutting edges, which operate in connection with suitable blades carried by the plate 2 to form parallel slits.
The base-plate is further provided with a pair of cutting-blades 12, arranged on divergent lines corresponding to the angles of the edges of the tongue, and these blades are slightly inclined, their rear edges being somewhat higher than the front edges, so as to act, in conjunction with the cutting edges, on the plate 2 to effect a shear cut. The base-plate is further provided with a pair of lugs or shoulders 14, arranged Aat the inner walls of the blades 12 and forming inclined supports for the tongue, so that the latter when cut will be immediately bent at an angle to the general plane of the base-plate and the sheets of paper or envelop thereon. The upper plate 2 is provided with a suitable opening having two inclined walls 15, arranged on lines corresponding to the angular planes of the tongue edges, and these walls serve as cutting' edges in connection with the blades 12. The forward end of the opening is approximately rectangular in form, and depending from its opposite parallel side walls are cutting knives or Iblades 16, that are adapted to cooperate with the cutting edges of the recess 9 to form the parallel slits in the paper. rlhe blades are preferably inclined, as shown, in order to form a shear cut; but the blades are so arranged that their cutting edges will but slightly pass below the upper surface of the base-plate, so that the undercut portions of the wallslO will be free and unobstructed and permit the sides of the tongues to pass thereinto. In order to force the intermediate portion of the paper downward, being that portion beween the two parallel slits,'a spring 17 is secured to the under side of the plate 2 and engages the paper between the two slits and forces the same down to the bottom of the recess, so that the parallel slits will beheld slightly open in readiness for the passage of the tongues.
On the top of the plate 2 is arranged a longitudinally-disposed slide 19, that is normally projected to a position slightly over the forward end of the opening by means of a compression-spring 20, suitable guides 21 being employed to maintain the slide in proper position. The rear end of the slide, or that portion which projects over the opening, is tapered and inclined in order to form a bendinganvil 22, on which the central portion of the tongue is bent in order that the side edges of the tongue may be brought nearer each other preliminary to their introduction through the parallel slits.
The upper plate 2 is provided with a pair of guiding- pins 25 and 26, that extend through suitable slats formed in a tongue-folding slide 27, and the lower portion of the front end of said slideV is provided with a V-shaped groove or recess that in part coacts with the similarly-shaped anvil 22 to form the fold in the tongue. lThe greatest depth of the recess is at the front end of the slide, and the upper wall ot' the recess from thence tapers gradually until it merges into the bottom line of the slide, so that there is formed a V- shaped slot of continuously-decreasing crosssectional area from the front toward the rear of the slide. The anvil 22 is shaped in corresponding manner and is in cross-section in the form of a triangle of gradually-increasing area from its pointed end toward the front of the slide 19, or, if desired, it may be slightly flattened. The slide 27 is normally maintained in a position to the rear of the cutters by means of a coiled tension-spring 30, andsaid slide is provided on one or both of its sides with pins or lugs 31, adapted to ride over stationary cams 32, secured to the bed-plate, during the advancing movement of the slide, this being for the purpose ot' permitting the slide to follow the folding movement of the tongue as the latter is bent over onto the anvil 22.
To operate the tongue-folding slide 27, said slide is connected tothe main operating-lever 6 by means of a chain or cord or link, as indicated at 34, and in some cases it may be desired to interpose a spring in the connection, as indicated at 35. During downward movement of the lever 6 the slide will be drawn forward and fold the paper tongue over onto the anvil, and will then descend as the lugs or pins 31 ride down the forward inclined faces of the cams 32 until the paper tongue is bent and clamped between the two slides.
To complete the folding operation, it is necessary or at least advisable to employ an aux- IOO 'reason iliary member for flattening the tongue, and thus insure the introduction of its edges through the parallel slits. For this purpose the slide 27 is provided with a guiding-opening for the reception of a presser-foot 40, which is held in elevated position by a small compression-spring 41. WV hen the slide has been moved to its full forward position and accomplished its work, a lugI 42, operatively connected to or formed integral with the lever 6, comes into contact with the head of the presser-foot and forces the same downward to flatten the tongue.
In the operation of the mechanism, thefolded sheets of paper or the envelops are introduced into the apparatus at a point between the base-plate and the plate 2, the paper be ing pushed toward the rear until its edge strikes against the rear edges of the blades 12, the latter being preferably elevated to form stops for limiting the movement of the paper. The operator then depresses the lever 6,
and the first effect of the movement is to cut the two pairs of slits by means of the blades 12 and 16 and their eoacting cutting edges. The blades 16, as before noted, extend down to a short distance below the upper edges of the slots 10, so that the undercut portions of these walls will be unobstructed. The paper tongue is held at a slight angle with respect to the base by resting on the shoulders or lugs 14. Then the plate has been fully depressed, continued forward and downward movement of the lever 6 will result in forward movement of the slide 27, and the front end of the latter will engage the partly-raised tongue and will force the same over on a bending-` line, determined by the length of the divergent. slits. To permit the slide to more accurately follow the folding movement, the cams 32 and `pins or lugs31 are employed, so that the slide will positively bend the tongue and will then descend on said tongue and clamp it on the anvil, the tongue receiving a longitudinal bend i to an extent su'llicient to reduce its apparent width to less than the distance between the two parallel slits. Continued movement of the lever will still force the yslide 27 forward, and the latter will, through the intervening paper, force the anvil slide forward, and the gradually-reducing areas of the slot and anvil will result in flattening' of the tongue and the forcing of its edges in lateral direc-` returned to its normal position by means of a chine.
suitable spring 4:5, and the paper er envelop then is left on the bed-plate, but is tosolne extent retained thereon by the insertion of the edges of the tongue in the recess of walls 10. The recesses are continued forward to the wider portion of the recess 9, so that by exerting a slight forward pull on the paper or envelop the tongues may be freed from the undercut walls and the paper removed from the maln some cases the spring 17 may be dispensed with and the anvil formed with a depending portion to engage with and depress the paper, as illustrated in Fig. 9.
As a further modification of the invention .the anvil'slide may be provided with a pair of depending spaced knives 50, which during the downward movement of the plate 2 are forced through the paper, and then on forward movement of the slide 27 the knives will cut slits of the proper length and remain at the forward ends of such slits during the insertion of the side edges of the paper tongue therethrough.
In some cases, especially where mailing-envelops are to be fastened or sealed by the machine, it may be desirable to perforate the envelop at points below the tongues in order to provide a readily-removable clip for convenience in opening the envelop. For this purpose the base-plate 1 is provided with a pei'- forated plate 52, having a large number of suitable perforations 53, forming the female dies for the reception of the perforating-dies 54, carried by the movable plate 2. The upper perforating-dies are carried by a transverselydisposed bar 57, that is normally held elevated by means of a spring 58 when it is not desired to use the perforator. When perforations are to be formed, the bar is pressed down and is locked in position by suitable catches 58, earried by the bed-plate.
It will of course be understood that the pai'- allel slits tl'lrough which the tongues pass may be disposed at an angle to each other, as indicated at c' in Fig. 1l), and in many eases such an arrangement is preferable, owing to the 'facility with which the tongues may be introduced.
1n Fig. 8 is illustrated a slight modification of the invention, wherein Athe eutting-recess of the base-plate is dispensed with and in its stead is used a vertically-movableplunger G0, guided in a suitable opening' formed in the base-plate and having its lower end supported by a longitudinally-movable wedge-bloch 61. l The rear end of the wedge is connected by a lever 63 and link (34 to an arm on the main shaft f1, so that during downward movement of the main lever the wedge will be moved from under the block (SO. lhe block 6() earries a pair of cutting-knives 65 to coact with cutters carried by the movable plate, and a depending spring-tongue 17 serves to engage that portion of the paper between the two slits and force the same down in order to IOO open the slits and permit the passag'e of the paper tong'ue. In the operation of this portion of the mechanism downward movement of the handle or operating-lever will first effect the cutting of the two slits, and then as the downward movement is continued the wedge-block 6l will be withdrawn from un der the cutter-block 60 and the latter will fall, so that its cutting edges or knives pass below the upper surface of the base-plate and permit the depression of the intermediate portion of the paper, so that the tong'ue may be more readily inserted.
The construction of the mechanism may be further modified in the manner shown in Figs. ll and l2, wherein the upper plate 2 is provided with a simple opening, the edges of which coact with the cutters and the base to form both sets of slits. In this construction the base-plate is recessed at lO and is further provided withshallow recesses for the reception of plates 70, the edges of which project over the parallel walls of the recess and are turned upward to form cutters 7l, that coact with the walls of the opening in the plate Q. This permits of the ready formation of slits, and the space below the knives 7l readily permits the entrance of the sides of the angular tongue during the folding operation.
It will be observed that the upper face of the main folder is provided with a rounded 0r curved cam-surface 72, so that during the final portion of the folding' operation the engagement of this surface with the head of the foremost guiding-pin will serve to positively depress the folder on the paper tongue, although this in all cases is not necessary.
