PARCEL-BUNDLING MACHINE.

Specification of Letters Patent.

Patented June 19, 1906.

- To all whom it may concern.-

Be it known that I, GEORGE HERBERT Ans- HEAD, a subject of the King of Great Britain *and Ireland, residing at 294 Stanstead road,

Forest Hill, London, S. E. England, have invented new and useful Improvements in and Relating to Parcel-Bundlin Machines, :of

- which the following is a speci cation.

The invention relates'to improvements in bundling machine's of the type described in my application for patent, Serial N o 182,922,

' filedNovember 27, 1903.

The'object of the invention is to modify the bundle-feeding mechanismso that more time may be allowed for the insertion of the bundle or pile of loose papers to'be bound.

, The invention consists, in a machine of the type indicated, in means for causing the main feeding-fingers to make substantially the whole of their return stroke in such a manner as not to interfere with the insertion of'a fresh bundle or pile of papers. The invention also includes means for closing the slots in the table through which the I i feeding-fingers pass. Referring to the accompanying drawings",

which form part of this specificatlon, Figures 1 and 2 show plan and end view of the feeding-fingers and vertical slides.

" detail of the spring-retaining catch.

Where desirable, the same reference-symbols have been used in the different drawings to denote corresponding parts.

In carrying the invention into effect ac-' cording to one form the feeding-fingers 3 are adaptedto pass through slots 2 in the table 1, carried by the frame a. These fingers pass through slides b, relatively to which they are capable of an up-and-down movement. The slides 12 are attached to a cross-bar c, this cross-bar carrying brackets (1, adapted to be reciprocated by the connecting-rod 6 and crank 7 on the slide-bars 5, as in the patent above referred to. times for convenience form the slides 12 and the brackets d in one piece. gers 3 are provided at their lower ends with the runners or rollers e, as shown. a In order to give the feeding-fingers 3 the desired up- I may some- The feeding fim' and-down movement, according to oneform (see Fig. 3) I. arrange top and bottom horizontal guides f and g, respectively, and inclined guides h '11, running in an upward direction from the -'ends of the bottom guides g, the former of these inclined guides being hinged. I also arrange other inclined guides k, pivoted or hinged to one end of the top function of these cams being by their motion to transfer the rollers without shock to the guides h, hinged at their lower ends to 'allow for thepassing of those parts of the cams more distant from their axes, the guides h being re turned by any suitable springs or the like. The feeding-fingers are in this way lowered beneath the level of the table 1, in which posi tion they make their return or non-operative stroke, the rollers being then supported by the bottom horizontal guides g. Toward the end of the return stroke the rollers pass along the upwardly-inclining guides?) and during this part of their movement push past the hinged guides 76. Finally at the commencement of the workin stroke the rollers pass up these hinged gui es 7a (which have meanwhile fallen back against suitable stops) onto the top horizontal guides f, the cycle of operations above described bein then repeated. In this manner the feedin gers are below the level of the table for a arge proportion of their return stroke, thus affording more time for the placing in position of a fresh bundle of papers.

According to a modified form of the invention (see Fig. 4J1 dispense with the various guides described above and use levers n, fulcrumed, for example, on the shaft 45. These The I levers are each provided with a long and short arm, the long arms having at their ends suitable surfaces 0 to receive the rollers. The shorter arms are weighted to such an extent as to overbalance the long arms, together with the feeding-fingers carried by them. A

disk r or the like carrying a pin sis adapted to engage the short end of each lever, respectively, in a manner to be hereinafter described. These disks may be mounted, for example, on the shaft 8 but any other suit- 5 able positions of the lever fulcrums and disks may be adopted. The action of this form of my invention is as follows: At the end of the return stroke of the feeding-fingers the shorter ends of the levers n are released by the pins 8 and fall, owing to the manner in which they are weighted, thus liftin the feeding-fingers. The working or forwar stroke then beginning, the feeding-fingers are transferred to the carriers t, which are pushed along the guides 5 by the advance of the slides b, a bundle being thus fed forward into the com- .pressing position. The first few inches traversed during the return stroke suffices to withdraw the feeding-fingers from the support afforded by the carriers, the feeding-fingers thereupon falling by their own weight. Any suitable spring-buffer or the like is provided to take up the shock of the fall. A lug, such as a, forming part of each feeder-arm, respectively, then rests on the top of the slide 1), in which position the greater part of the return stroke is completed. Toward the end of the return stroke, however, the pins 8 escape from the short ends of the levers, which they have in the meantime raised, thus allowing the weights to raise the feeding-fingers again to their working position, when the above cycle of operations is repeated. It will be seen that the carriers t are returned by the hooked pieces 4), attached to the slides 6. According to yet another modification, which I prefer to those above described on account of its greater simplicity, (see Figs. 6, 7, and 8,) I mount a chain-wheel 9 rigidly on the crank-shaft 8 and connect this by a chain to a similar wheel 10, which I mount loosely on its shaft. A link 11, pivoted at one end to the chain-wheel 10 serves to transmit motion from the latter by way of the lever 12 to the rocking shaft 13, on which the levers 141, slotted at their free ends, are mounted. These slots engage, respectively, with pins 15, mounted on the carriers 16, adapted to slide in the fixed guide-bars 17, the rollers e of the feeding-fingers 3 being adapted to rest on these carriers while lifting takes place. I wish it to be understood that in order to show the different parts of the mechanism as clearly as possible the chain-wheels 9 and 10 are not represented as set in their correct relative working positions. I preferably arrange these so that lifting of the feeding-fingers commences before the crank has reached the dead-point at the end of its non-feeding stroke and ends more or less symmetrically on the other side of this dead-point. The whole lift is thus effected With a minimum traverse along the guide-bars 5. In order to prevent return of the feeding-fingers when 65 lifted into their Working position, I arrange a catch or pawl 18 (see Fig. 9 pivoted to each of the slides 19 and pressed by the spring 19 to enter a notch in the feeding-fingers 3. At the end of the feeding-stroke a tailpiece 20, attached to this pawl, abuts against any suitable stop, thus releasing the feeding-fingers, which then fall by their own weight. The action of this modification will be readily understood in view of the foregoing description without further explanation. The invention also includes means such as adjustable bars, stri s, or the like for closing the slots 2 in the tab e through which the feedin -fingers pass.

According to one form, as shown applied to the feeding mechanism of Fig. 4, the slotclosing device may consist of strips w, checked into the edges of the slot, as shown in cross-section in Fig. 5, the strips being attached to the slides I), or according to a modification flexible bands 51:, made, for example, of leather, or similar to those used for manufacturing bandsaws, may be employed, these strips being likewise attached to the slides b and held taut by weights ,2 or other suitable tension device, as seen in Fig. 4.

In some cases I may close the slots by moving strips thereover in a direction at right angles to the movement of the feederarms. Slot-closing devices of the nature described are preferably arranged both. in front of and behind the feeding-fingers.

I have found when developing the underlying idea ofmy inventionviz., the modification of the feeding-gear shown in my previous patent so as to obtain more time for the insertion of a fresh bundlethat it may be embodied in a variety of different mechanisms. The examples which I have given, how ever, of which I consider that shown in Figs. 6, 7, and 8 the most satisfactory, sufficiently indicatethe scope of my invention.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In combination in a machine of the class described, a table, a bracket reciprocating beneath the same horizontally, feed-fingers slidable vertically through the said bracket and means controlling the elevation of the feed-fingers in respect to the table whereby they will be projected above the same for the feeding stroke and will be lowered for the return stroke, substantially as described.

2. In combination in a machine of the class described, a feeding finger movable vertically in relation to the table or surface over which the material is to be fed, and means for lowering the said feed-finger on its return stroke to avoid contact with the material, said means including a lifting-lever, substantially as described.

3. In combination in a machine of the class described, a feeding -finger movable vertically in relation to the table or surface over which the material is to be fed, and

' "means ior lowering the said feed-finger on its return stroke to avoid contact With the material, said means including a lifting-lever and means for holding the finger up and adapted to be disengaged therefrom when a certain position'is reached, substantially as described.

4. In combination in a machine of the a tion to the table, means for moving the feedfingers along the talble, a table slotted for said fingers and means for closing the slots along which the feeding-fingers pass, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
