Description
Jan. 8', 1924.
S. M. LANGSTON S HEET STACKER Filled Feb. 7, 1925 Patented Jan. 8, 192%;
err rs mean f ran SHEET STACKER.
Application filed February 7, 1923. Serial No. 617,436
To all whom it may concern:
Be it known that I, SAMUEL M. LANG- s'roN, a citizen of the United States, and resident of Wenonah, in the county of Gloucester and State. of New Jersey, have invented certain new and useful Improvements in Sheet Stackers, of which the following is a specification.
In my copending application, Serial No. 556,739, filed Aprll 26th, 1922, which resulted in Fatent No. 1,446,570, dated February 27th, 1923, I have disclosed a machine for stacking sheets having apertures, notches, transverse slots or slits, or other form of outline which may present edge portions intermediate of the front and rear edges of the sheet and extending at an angle to the general direction of sliding movement of the sheet on to the top of the stack. The main feature of said machine which is broadly claimed in said patent is. a stack support which is so constructed that the portion of the sheet which is at the side of a slot or slit nearest to the sheet delivering means is supported at a higher elevation than the ortion at the far s de of the slot or slit. y means of this construction each sheet may be slid onto the top of the stack without catching on the edges of the sheet which at the time forms the top of the stack. V
The specific machine illustrated in said patent 18 designed for the stacking of shingle strips and the means for securing the'desired variation in elevation of the portions at opposite sides of a notch or slot includes cam projections on the support and at the side of the slot which is toward the sheet delivering means. Although such projections operate perfectly for the purpose specified, they interfere with the use of the stack support in case plain or unnotched sheets are to be stacked thereon, and may interfere with the sliding of the entire stack off the stack support.
' The main object of my present invention is to provide a novel means for securing the desired variation in elevation of the parts of the sheet at opposite sides of a notch or slot, which means will not in any way interfere with the stacking of unnotched or unslotted sheets on the support, and will insure the roper delivery of sheets onto the top o the stack without any crumpling of the sheets or catching of In the accompanying drawings:
Fig. 1 is a sectional detail of a portion of a sheet showing a stack support and sheet delivering means.
Fig. 2 is a sectional detail similar to a portion of Fig. 1, and showing a top sheet advancing onto the stack. Fi 3 1s a plan view of a sheet or pluralitp 0 sheets which ma be stacked by means 0 my improved macl iine.
Fig. 4 is a plan view of the stack sup port for sheets of the form shown in Fig. 3. Fig. 5 is a perspective view of a portion of the sheet support, and
Fig. 6 is aperspec-tive VlBW of the parts 7 shown in Fig. 5 with a sheet thereon.
In the machine illustrated the sheets are delivered between a pair of superposed rollers 10 and 11 which are mounted on a vertically movable carriage 12. The sheets are conveyed to these rollers by a belt or series at the desired rate. The stack support is illustrated as being mounted on the rollers 18 whereby the stack support may be moved laterally and replaced by a new one when the stack has reached the desired height. The general relationship of the parts so far described may be substantially the same as is described in my prior patent above referred to.
As the important feature of my present invention the stack support 14: is provided with recesses, depressions or pockets 1.9 which are so positioned that they" permit the portion of the sheet directly beyond each slot or notch to drop down to a lower level than the portion at the side of the slot nearest to the sheet delivering means In Fig. 4 I have shown a stack support upon which shingle strips of the form in v Fig. 3 may be stacked. These shingle strips A have tabs or 'ro'ections B separated by slots or notches or this form of shingle strip arranged as shown in Fig. 3, the support 14 may have three of the notches 19 which have vertical edges 20 adapted to register with the slots, and downwardl'yconverging faces 21 meeting on a linereg1stering with the dividing line between two of the sheets. Where the slots of one sheet do not register with those of the'a djacentsheet the notch of depression would have only one downwardly inclined surface 21, and two vertical edges, one registering with the slot and the other with the side :edge of the sheet. As the first sheet moves endwise onto the support, ,the portion of each tab or projection beyond a slot C will have its corner portion drop down into the depression so that substantially the entire edge of the tab or projection B beyond a slot will be lower than the opposed edge of the tab or projection which is on the side of the same slot toward the' sheet delivering means. Thus as the sheets slide into place, each one has appropriate portions drop down and the edges are protected so that successive sheets may slide into place without any liability of; one catchi on the other and thus interfering with te proper stacking.
Having thus described my invention, what ll claim as new and'desire to secure by Letters Patent is:
l. A machine for stacking slotted sheets, including meansfordelivering the sheets edgewise in succession in a direction at an angle: to'the general directionof the slot,
and a stack support having means for holding the portion at the far side of the slot at a lower elevation thanthe body portion of the sheet.
2. A machine for stacking slotted sheets,
, including means for delivering the sheets edgewise in succession in a direction at an angle to the general direction of the slot,
and a stack support having a portion depressed below the general plane of the sup port for registering with the portion of each sheet at the side ,of' the slot farther from said delivery means when the sheet is in final position. a
3, A machine for stacking slotted sheets,
including means for delivering the sheets are in final position,
6 A machine for stacking shingle strips having a series of spaced tabs or projections neraeei along one edge thereof, said machine including a stack support having a recess on the upper surface thereof for-holding in downwardly tilting position a corner portion of certain of the tabs or projections of the shingle strip. a
A machine for stacking slotted sheets, including means for delivering the sheets edgewise in succession in a direction at an angle to the general direction of the slot, a stack support having a depression on the upper surface thereof, the edge of the projection nearest to the delivery means registering with the slot of the sheet when the latter is in final position, and the surface of the depression beyond said edge being inclined downwardly from the surface of the support to said edge.
' 6. A stack support for shingle strips havirr'g a series of depressions each of a length substantially equal to the length of the corresponding slots in the shingle strips and having a substantially vertical face registering with the slot and a face inclined downwardly to said vertical face at a comparatively small angle.
7. machine for stacking a plurality of simultaneously delivered shingle strips each having laterally facing projections or tabs, said machine including a sheet delivering means and a stack support, said support having means for holding in a downwardly tilting position the outer corners nearest to the delivery means of each of the shingle strip projections. v
8. A'stack support for shingle strips including a supporting board or platform and a depression thereon, said depression having a substantially verticaledge for registering with the slot between adjacent tabs of the shingle strip and a vertical edge for registering with the side edge of the strip, the surface of the depression between said vertical edges being inclined upwardly and merging into the main surface of the support.
9. A stack support for shingle strips including a supporting board or platform and a depression thereon, said depression having a substantially vertical edge for registry with the opposed slots of two adjacent shingle strips, said vertical surface being substantially triangular, and a surface inclined upwardly from said vertical edge and merging into the main surface of the board or platform.
