PAPER-TAPE FOLDER.

Application filed September 4, 1915.

To all zc/wm it may concern.'

lie it known that I, VILLIAM H. MGBRIDE, a citizen of the United States, and a resident of the city of St. Louis and State of lvlissouri, have invented a certain new and useful Improvement in Paper-Tape Folders, of which the following is a specification.

This invention relates to a new system of handling and preserving records in strip form, and more particularly to folding up into book form such long narrow strips of paper as are used in adding machines for recording the items totaled. The invention has for its objects to make up such strips .3 or tape into a form which is convenient for handling and inspection, and which is compact and adapted for tiling and for permanent preservation.

Further objects and details of the invention appear in connection with the following description of a suitable folding machine for performing the invention; and what the invention consists in is more particularly defined in the appended claims.

In the accompanying drawings, wherein the same reference characters designate like parts in the several views,

Figure 1 is a front view of a suitable machine for carrying out the invention, showing a tape inserted ready for folding;

Fig. 2 is a plan view of the machine shown in Fig. l;

the tape completely looped and the cover inserted prior to pasting;

Fig. G is a View similar to Fig. 5 of the drum and tape, showing the loops folded around. the drum ready for pasting; and

Fig. 7 is a perspective. view of the com pleted book.

The folding machine shown in thev drawings, comprises a base 10 provided with front and rear pedestals 1l in which is mounted a horizontal axle 12. A drum 13 is jmlrnaled for oscillation upon the axle 12. Below the drum is a transversely curved blade 141., which secured to a cross web 15 connecting the pedestals. The blade 14 is arranged horizontally, and extends nearly from. end to end of the Specification of Letters Patent.

to its under side. The curve of the blade 14 follows the outline of the drum, and the front edge of this blade is sharp and lies close against the surface of the drum for stripping olf the loops of tape as they are formed. A vertically movable angle clamp 16 is slidably mounted on the web portion 15 of the frame beneath the curved blade 14. The vertical leg of the angle clamp is arranged below the back edge of the curved blade 14, and the horizontal leg is normally held up against the rear portion of the curved blade tangcntially thereto by means of a bell crank lever 17. The curved blade la and the horizontal leg' of the angle clamp 16 together form a clamping means for holding the loops of tape as they are formed. A finger or latch 18 which is pivoted to the upper arm of the bell crank lever engages under the angle clamp at its middle. The end of the pivoted finger is held in the angle between the vertical and horizontal legs of the angle clamp by means of a small spring.

The bell crank lever is fulcrumed in the base, and its upper arm extends under the drum transversely of its middle and is held up by a spring 19 located in the base. One end of the spring is connected to the lower arm of the bell crank lever and the other end is attached to a nut 20 which can slidein a' narrow space in the base. The nut 2O is mounted on an adjusting screw 2l, the head of which projects through the side wall of the base where it can be reached with a screw driver.` The tension of the spring can be adjusted by means of the screw and nut to suit the paper being folded. The upper end of the bell crank lever has a thumb portion 22 for depressing it to remove the folded tape. 1

rThe base or frame has a slot 23 through it on the side of the drum from which the tape or strip of paper is fed for guiding it. The length of this guideslot is adjustable for various widths of paper by means of the guide lingers 211 which are slidable along a graduated rod 25 secured to the base alongside of the slot.

The drum 13 is fitted with a pivoted operating handle 26 for oscillating it back and forth, and this handle is connected by means of the link 2.7 with the cranked end 28 of the paper clamp rod29. The opposite ends of the clamp rod 29 are provided with offset or crank portions 30 which are journaled in brackets on the' edges of the drum. A paper folding blade 31 is attached to the ydrum alongside of the papeil clamp rod 29 yandy parallel to and spaced slightly from the surface of the drum. This folding blade .is a tightly stretched thin ribbon of steel, and is graduated like the rod 25 for centering the paper on the drum.y rlhe graduations may be marked on the drum instead of on the folding blade if desired.

The drum is fitted with a full stroke device comprising a swinging friction detent 32 pivoted on the front pedestal 11 between it and the end of the drum. The lower end of the detent 32 frictionally engages the inner surface of the projecting front edge of the drum bariel, and is held in engagement therewith by one or the other of the two retaining springs 33. The projecting edge of the ydrum has two depressions or holes 34, which are arranged to engage 'the detentrespectively at the ends of the forward and ret-urn strokes of the drunito reverse the detent. the base bears against a raised strip 36 on the edge of the drum at the end of the return stroke or half oscillation of the drum, and this retards the beginning of the looping stroke sufliciently to insure that the handle 26 shall swing aroundL and throw the paper clamp rod 29 into clamping position to feed the paper tape for making the loop. A similar retarding action occurs at the beginning ofthe return stroke, due to the folding blade 31 being frictionally held by the clamping means forthe loop, thereby causing the.

handle to swingy back and raise the paper clamp rod from the drum to permit the y paper to run freely beneath it. A stop 37 on the edge of the drum limits the length of the return stroke and thereby determinesy the length of tape picked up for each loop.

The operation of the device is as follows: 'The tape is led through the guide slot 23 and over the drum passing under the clamp rod 29 and folding blade 31, and five or sin inches of its length `is pulled through be-y neath the folding blade, as shown in Fig. 1. The drum is rotated in the direction of movement of the tape bymeans of the handle until the folding blade'brings up'against the web 15 and between the curved blade 11i and the angle clamp 16. During this stroke Y the handle holds the clamp rod 29. tight Les against thekpaper, thus causing the paper toy be carried karound with the'drum. The direction of movement of the drum is then reversed, and the folding blade is withdrawn from between the angle clamp and curved blade, leaving the folded end of the loop caught between the two. The paper clamp is automatically raised during the return stroke, and the paper remains motionless, the drum rotating beneath it. At the end of the return stroke the motion of the drum is again reversed, and a second looping stroke A friction spring 35 on is made. The direction of movement of the drinn can be yreversed at either' end of the stroke, thereby reversing the position of the detent 32 g'but the detent 82 prevents 'reversing the direction of movement of the drum the curved yblade 14, as shown in Fig; 5. i The open ends of the loops are swung up against the drum with one hand, and paste is applied to their overlapping extremities by means of a brush held in the other hand, after which the free end of the tape which was rst pulledthrough the folding blade y is brought up and laid over the pasted ends ofthe loops and against the cover and pasted thereto, as shown in Fig. 6. The free end of the cover is next folded down over the pasted ends uof the loops, and the book is complete and may bey removed from the clamping blades by pressing down the thumb key 22 kon the end of the bell crank lever. The unpasted extremities of the loops when freed from the clamping blades assume overlapping positions conforming to the overlapping at the pasted ends, thereby making easy turning of the leaves for inspecting their contents.

It is evident that changes in the forms and arrangements of the parts may be made, and the invention is not restricted t0 the parts andarrangements shown and described.
