STACKING- DEVICE FOR HORIZONTALLY-FED FLAT ARTICLES.
Application filed-October 17, 1913. Serial No. 795,749.
resident of Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Stacking Devices for Horizontally- Fed Flat Articles, of which the following is a full, clear, and exact description.
This invention relates to improvements comprised in a Stacking mechanism of a machine in which fiat articles are su ccessively horizontally fed to a given position andaccumulated into a pile or stack, each of the articles being brought to and forming part. of the stack, being supplied to the latter at the bottom thereof. Y The improvements in the stacking device have been employed in, or as a part of,'an envelop sealing machine, but the use thereof is not necessarily limited to such a machine, but is applicable on other descriptions of machine. a
The improvement in part especially pertains to a compression bar or member which gravitatively bears upon thetop of the stack of envelops, or other articles, and recedes upwardly as the stack under accumulation becomes higher.' The particular features of improvement in the compression bar reside in the provision of a vertical extension which is slidable in relation to a stationary upright member, and which extension has axially horizontal rollers adapted for rolling bearing on the front and rear faces of said upright member at difierent points in the height of the latter' whereby the tendency for cramping or binding between the slidably engaged parts, due to the Slight,
swinging motionandleverage action of the compression bar will be provided against by the rollers peculiarly relatively arranged and located to such end.
In conjunction with the compression bar or device further rollers are additionally and peculiarly employed for coaction with the upright member onwhich the device is vertically engaged for further increasing theease and certainty of its receding action in the upward direction.
,The improvement also in part especially pertains to the provision in the stacking device of a vertical gage stop which is horizontally adjustable as occasion may require Specification of Letters Patent.
, Patented May 16, 1916.
to adapt the stackingframe for the reception of envelops or pieces of varying Sizes,
the novelty therein particularly residing in the means for effecting the adjusting movements the gage stop and for constraining or guiding the movable supporting member of such stop in its movements.
The invention is described in conjunction with the accompanying drawings and is set forth in the claims. I o I In the drawings: Figure 1 is a sectional elevation of an envelop Sealing machine at the left hand portion of which the stacking devices including the present improvements are represented. Fig. 2 is a vertical sectional view on a larger scale through the improved adjustable gage stop. Fig. 3 is a cross section on line 33, Fig. 2. Fig. 4: is a plan view of the compression bar and the upright member with which it coacts. Figs. 5 and 6 are sectional elevations'with parts of the feeding and stacking devices of the machine shown in somewhat different operative relations, and showing the stack topping member or compression bar as in employment in relation thereto. Fig. 7 is a partial face view of the device as the same- In the drawings, A represents generally the frame work of an-envelop sealing madcvices are provided. Briefly, the envelops are. supported, in a pile, on a horizontal plate B, being, restrained against displacement: The envelops are by a horizontal feed plate 0, after the flaps thereof are moistened chine, atthe left hand end of which, herein referred to as the forward end, the stacking by the revoluble moistener head D, pushed one after another between the press rolls E and F where they are engaged and further carried by the duplicated revoluble members G which advance them to the upright gage stopJ and also impart elevating suitably supported, j and advantageously.
;made of comparatively thin, though rigid rear 1 and 6. tical extension P disposed alongside of the plate or sheet metal and having a vertical slot at therein. The said slot preferably opens to the upper end of the upright member 1V1; but the separated upper portions of such member are reinforced by the rigid metallic strap 6.
0 represents the horizontal compression member which is to bear upon the top of the stack as rendered apparent in Figs. 5 This bar 0 has a right angular, ver
rear face of the upright member M, and it has aihxed on the forward side thereof a block or bracket Q-w-hich extends through the slot (1, and beyond the forward face of the upright member M; and this block or bracket is provided with an angular extension Q adapted to project oppositely, that is rearwardly for a suitable distance beyond the rear face of the upright member.
The bracket at its portion which is for ward relatively to the upright slotted meminclination forwardly and upwardly; but
i this slight swinging effect is ineffective to cause a cramping or binding of the bar extension in its engagement with the slotted upright M for the reason that rollerbearings (Z are operable against the rear face of the upright, and roller bearings f are operable against the front face of the upright, and at a higher point. Provision is also made whereby clamping or binding is prevented in case any force is exerted to tilt or swing the horizontal compression barO transversely, and the same will be now described.
The bracket Q in its. side which adjoins the vertical extension or shank P of the compression bar is made with recesses g 9, one higher than another, in which axially horizontal rollers 71. are located, the same. being carried on axle studs 2' therefor, screw threaded end portions of which are connected into theportions of the bracket forward ofthe recesses g. A considerable portion of the length of each screw iscylindrical, or plain, and the head at its forward end is let into a countersink in the centrally bored roller,reference being especially directed V to Fig. 8. The pair of rollersh h are diametrically slightly less than'the width of the slota in the upright, so that the opposite edgesof-both rollers will not simultaneously touch on the opposite edges'of the slots, but if the appliance O, P, is bodily crowded in a direction toward one side of the slot at,
formed with an aperture or slot m therein as shown in Figs. 4 and 9, thereby leaving space for occupancy of one of the revoluble members G comprised in the feeding and stacking mechanism. The vertical gage stop J has an angular foot extension 0 which has a supporting connection on a block 1", which block in turn has a supporting and also a slidable engagement with a horizontal bar R which is arranged lengthwise of the machine and which has the channel 8 therein forming the guide for the block.
' T represents a screw shaft extending centrally through the channel in the bar and with a screw engagement through the block; and this shaft as clearly seen in Fig. 2, is so mounted that it is incapable of endwise motion but it has aknob or handle T on its forward end by means of which it may be conveniently turned to effect the adjustment in a forward or rearward direction of the gage stop J. The dotted lines in Fig. 2 indicate the changed position of the gage stop J and the movable supporting block therefor.
