SIGNATURE-GATHERING MACHINE.

SPECIFICATION forming part of Letters Patent No, 768,461, dated August 23, 1904.

Application filed July 18, 1900. Serial No. 24,017. (No model.)

.To all whom it may concern:

Be it known that 1, CHARLES A. J UENes'r, a citizen of the United States, residing at Oroton Falls, in the county of Wcstchester and State of New York, have invented an Improvement in Signature-Gathering Machines, of

which the following is a specification. My invention relates, to that part of signature-gathering machines Where the signatures as delivered upon a carrier and superimposed upon supporting devices above the line of travel of the carrier, Wh1ch group of signae tures or sheets as lifted comes beneath the stack of slgnatures or sheets to increase the mass upon the same common supports. These parts are yielding and preferably spring-con trolled. The lifting-blades are connected to a common support uponwhich they are adjustable and the vertical movement of the lifting-blades and common support is effected in any desired manner.

, 1n the drawings, Figure 1 is an end eleva tion of a frame and the devices of my improvement. Fig. 2 is a vertical section and partial elevation on the dotted lines w 00 of Fig. 1.

The frame a is one of a series employed in a signature-gathering machine and specifically the end frame of the machine.

5 represents a bed-plate, and 6 an upright plate, the tWo parts forming a bracket secured by bolts 2 to the outer surface of the This bracket structure is provided With bearings 3 4, preferably in pairs, and With a pair of bracket-arms 5. The bed-plate bof the bracket structure is provided With an extension or arm Z2 slotted to receive the guide-post 0, secured to the bed-plate of the bracket by the nuts 6, Which preferablycomes at opposite sides of the extension or arm I provide other guide-posts c c in pairs,

the posts a being connected to a bracketrarm or support (Z upon the frame a, and the guideposts 0 connected to a movable arm d, which 'post 0 coming at the end of the line of travel of the signatu'res'or sheets upon the carrier and also at the end or outside of the signatures or sheets in the stack upon the higher plane. r

c represent offset bars forming slides of the signature-raceway, and f is a signaturecarrier, the same having bracket parts f thereon at intervals and transversely of the carrier for moving the superimposed signatures or sheets along by a movement imparted to the carrier. The movement of the carrier, the devices for actuating the same, and the manner of feeding along the signatures or sheets thereby form no part of my present invention. A

9 represents. the superimposed signatures or sheets. These at their opposite edges lie upon the offset bars ac, Which form guides therefor, and at an intermediate point upon the signatureecarrier f and upon a fixed longitudinal bar f so that they are supported not only at the edges, but at the intermediate point, and are thus kept in form. I employ a series of lifter-blades 7L, preferably of the form shown in Fig. 2--that is, With a convex curved upper edge, over which the group of blades is provided with a base-bar it, the basebar being undercut at the right hand side Each of these lifter-- (see-Fig. 2) and at the left-hand side having a bar-8 with an undercut edge, which parts taken in their combined relation are adapted to engage and be clamped to the platform '1'. This platform has opposite inclined edges to fit the undercut edges of the said base-bars and bar 8, and when the nut clamping the bar 8 is loosened to slightly free the bar the said lifter-blades can be moved longitudinally of the platform 2', so as to adjust the same to the desired position.

70 71: are rods parallel, set vertically and passing through the bearings 3 L of the upright plate 6 of the bracket. The upper ends of these rods 70 7c are secured to the under surface of the platform 2 Adjacent cranks Z on a shaft Z in the brackets 5 as bearings together form a bell-crank lever, to one end of which the connecting-rod Z is pivotally secured. To the other end of this bell-crank lever one end of a link m is connected, the other end thereof being pivotally mounted to a block or sleeve of the rod Z2. The connecting-rod Z is actuated by any suitable mechanism or power to impart a swinging movement to the bellcrank-lever device Z and shaft Z. It will be seen that this movement aetuates the link m and raises and lowers the rods Z; 70 and the platform 71, imparting to the lifter-blades II, a vertical motion.

a 0 are yielding support-plates, shown as of curved form, connected at their lower ends to hinge-blocks a 0, pivoted to the hinge-plates 9, which in turn are secured to the upper surface of the bed-plate Z) of the bracket structure, and I employ springs 9, at one end connected to the hinge-plates and at their other ends to pins in the yielding support-plates a 0. These plates n 0 are preferably formed with stop-blades 10, which come outside of the lower ends of the pairs of guide-posts 0 0 while the upper ends of the support-plates 12/ 0 rise preferably higher than the upper ends of the blades 10 and come between the pairs of guide-posts 0 c to support the stack of superimposed signatures or sheets which rest on the upper ends of said plates a 0. I prefer to give a slight curve to the upper edge of the plates n 0 similar to the curve of the upper edge of the lifter-blades h, the function of the springs 9 being to maintain the sup port-plates a 0 inan initial position, in which the upper ends of the stop-blades 10 come against the outer surfaces of the pairs of guide-posts c 0 In the operation of the device and as the superimposed signatures or sheets are brought along progressively by the carrier f an upward movement is imparted by the connecting-rod Z shaft Z, and bell-crank-lever de: vice Z to the rods 7'; Zn, platform z', and series of lifter-blades it. These lifter-blades as they rise take with them the pile of signatures or sheets 9, raise the same against the yielding support-plates w o and the under side of the stack of signatures or sheets. In so doing they push aside the yielding sup1mrtplates w o and raise the stack of signatures or sheets sufficient for the sup eiort-plates o to return beneath the lowermost signatures or sheets. As the lifter-blades descend the signatures or sheets just raised form part of the stack and are left upon and supported by the supportplates a 0, the series of lifter-blades /1, the platform 1', and the rods Z? Z1 descending to their lowest position ready to receive upon 'said blades the next pile or group of superimposed signatures or sheets from the carrier with its progressive movement.

I do not herein limit myself to the precise, construction of the yielding sup1')ortplates u 0, but prefer to limit myself to forming the series of curved lifting-blades Z1 andthe support-plates a and o with convex curved upper edges, because thereby distinct functions are performed, namely: The groups of superimposed signatures or sheets easily overrun the lifter-blades as advanced by the carrier, and said signatures or sheets as lifted by the blades and as supported by the support-plates a and 0 readily conform to the said curved upper edges and in so doing assume the form of a flattened arch wherein it is substantially impossible for the signatures or sheets to sag.

I claim as my invention* 1. In a signaturegathering machine, the combination with a carrier for successively delivering superimposed groups of sigmuaires or sheets, of devices in line with the carrier having convex curved upper edges adapted to receive upon them the groups of signatures or sheets, means for raising said devices with each group of signatures or sheets and yielding spring-controlled devices in a higher plane adapted to receive and support the groups of signatures or sheets m ii/(MW as successively raised and stacked.
