Specification of Letters Patent. Patented Dec 30, 1919 7 Application filed June 25, 1919. Serial m. 306,728.
To all whom it may 00mm.-
Be it known that I, HAROLD C. HARVEY, a citizen of the. United States, and resident.
of Milwaukee, inthe county of Milwaukee and State of I/Visconsin, have invented cer- Paper-Feeding Mechanism; and I do hereby declare that the following is a full, clear,
and exact description thereof. y
This invention relates to new and useful improvements in machines for feeding sheets of material, such as paper blanks used in the manufacture of bon bon cupsand similar articles.
Heretofore it has been customary, in
mechanisms of this character tohave a pair of sheet removing and supporting members operable through a blank holding magazine from one side to the other thereof as shown in United States Patent No. 1,238,138,
dated August 28th, 1917. In the mechanism mg a considerable portion of time. The direct result of this is that the stack is disarranged repeatedly and the accuracyof op eration and the consequent uniform removal of blanks is impaired. I I y My invention hereinafter described is designed to have both the blank removing member and. the stack supporting member operable from the same side of the magazine holding the stack to thereby decrease the space necessary for mounting the mechanism, and improve the uniformity of operation. This latter is carried out byretaining the supporting member in position to receive the stack until the blank removing member is projected therethrough, and likewiseretaining the blank removing member in pos tion to support the weightof the stack, after the supporting memberhasbeen retracted and thesevered blanks allowed to drop from the stack, until the supporting member is returned to its initial position, that is ina position to receive the stack.
It is also an object. of the presentinvention to provide anarrangement whereby a number of the blanks in a stack are pressed together until the blank removingmember has been projected therebetween, where upon the pressure'is released. I
A still further objectis to provide an arrangement for positively projecting and retracting in synchrony the blank removing and supporting members in contradistinction to the manner illustrated and described in the above referred to patent.
With these and other objects and advantages in view, the invention consists in the novel features of construction, co1nbination and arrangement of parts which will be hereinafter more particularly described and claimed and shown in the drawings:
In said drawings:
Figure l represents a plan View, partly in section, of a paper feeding mechanism constructed in accordance with my invention.
Fig. 2 is a transverse sectional view taken on the plane of the line 22 of Fig. 1.
Fig. 3 is a longitudinal sectional view on the plane of the line 38 of Fig. 1, and
Figs. 4:, 5, 6, 7 and 8, are detail diagrammatic views illustrating the several steps in the removal of one or more blanks from a stack containing a pluralty of the same.
My mechanism being capable of use with slight modifications in many different arts where it is necessary to feed sheet blanks, I have not illustrated it on any particular type of machine, it being merely mounted on a table lby means of bolts or the like 2 which extend through feet 3 projecting from opposite sides and the end of a base plate 4:.
The inner end portion 5 is adapted to formthe bottom of a magazine, the vertical elements of which consist of rods 6 arranged in the form of a rectangle and secured to the portion 5 of the plate. Saidportion 5 also has anopeni'ng 7 through which the blanks B may drop when theyare severed from the stack located between said rods. After passing through'the opening 7 the blanks are conveyed away from the mechanism, formmy invention to the point of the next operation. e
The outer end portion of the base plate 4: is provided with a pair of longitudinally eXtending guideways 8 and 9, the walls of each ,of which are preferably dove-tailed as shown in Fig. 2, to receive slides 10 and 11, the slide .10 being reciprocatory in the way 8. while the other, slide 11 is similarly located in the way 9.
A bracket 12 is secured to the table 1 ad'- jacent the plate a and has fulcrumed thereto levers 13 and 14;, the pivots of which are spaced apart as shown in Fig. 1. One end of each of the levers is provided with. a cam pin or a cam roller 15, these parts of the levers l3 and 14 being adapted to ride in cam grooves 16 and 17 respectively of a double faced cam member 18. This cam member is fixed'upon a shaft 19 which is rotated at any desired speed and by any preferred means.
The opposite end of the lever 13 from the member 15 is connected to the slide 11 by a link 20, and the other lever 14 is similarly connected to the slide 10 by a link 21. It will be seen from this construction that upon rotation of the cam member 18, the levers 13 and 14: will be rocked independently of each other to independently reciprocate the slides 10 and 11. At times both of the slides may be moving together, while at other times one may be stationary and the other moving, and vice versa.
Adjustably fixed to the slide 10 by means of set screws 22 is a support 23, the actlve end of the same being oifset from its attaching portion 23 for moving between certain of the magazine rods 6 and over the opening 7. That is to say the support extends in the direction of movement of the slides 10 and 11, but is disposed centrally of the plate 4: and between the ways 8 and 9 thereof. Adjustment of said support is procured through said set screws 22 and slots 24 in the attaching portion 23 thereof.
A blank removing member or blade 25 having an attaching portion 25 is carried by the slide 11, said attaching portion having slots 26 whereby set screws 27 may adjustably secure the same to the said shde. The inner end of the attaching portion 25 is considerably thinner in transverse section than the outer end thereof so that when necessary the active end of the blade 25 may be vertically adjusted toward or away from the support 23 by the proper movement of the innermost set screw 27.
A yoke 28 is disposed transversely of the plate 4 and straddles the ways 8 and 9 therein, it having a centrally positioned detent lug 29 for cooperation with the notch 30 in the shiftable bar 31. This bar rides on said detent and in the bearing of a bracket 32. The inner end of the rod carries a pressing finger 33 which is moved. toward and away from the stack of blanks B in the magazine, this movement being in unison with the slide 11. Such movement is procured through a latch plate 34 on said slide which is operable in the seat of a stop mem ber 35, the lever being frictionally secured to the bar 31. Adjustable weights 36 retain the bar in engagement with the detent lug 29, and a stop 37 limits the movement of said rod in a direction toward the magazlne.
Referring particularly to Figs. 4 to 8, it will be seen that the operation of my invention is substantially as follows: Under normal conditions the stack in the magazine formed of a plurality of blanks B rests upon the support 23 which is projected between the rods 6 of the magazine, and the pressing finger 33 and the blade 25 are entirely out of engagement with the blanks. Now when operation of the machine is commenced, the slide 11 will be moved inwardly to project the elements 25 and 33 toward the stack, the pressing finger 33 being in advance of the blade 25, will first engage certain of the blanks B slightly about the support 23. The rod at this time is riding over the detent lug 29, but as soon as it has been shifted inwardly a suflicient distance, the notch 30 will engage said lug 29 to cause a depression or lowering of the finger 33 toward the support 23. The blanks between said finger and said support will thereby be compressed.
While still under pressure, the blade 25 is moved into engagement and between cer' tain of the blanks B between said pressing finger and the support 23. The distance of the blade 25 above said support will determine the number of blanks B to be removed from the stack, but before the blade moves between the blanks to any great extent, the pressing finger 33 will be raised to release the pressure and allow the former to be more readily passed through the stack. This releasing is obtained by moving the notch 30 out'of contact with the detent lug 29.
After the blade 25 has been projected completely through the stack so that it will support the weight of the blanks thereabove, the support 23 is retracted as indicated in Fig. 8, the blank or blanks between the same and said blade being permitted to drop by gravity through the opening 7, and-the blade remains thus until the support is again pro jected by the inward movement of the slide 10 so that upon withdrawal of the former, the reduced stack may settle upon the latter. The pressing finger 33 is obviously returned to its normal position upon the retraction of i the blade 25. This cycle of operations is repeated over and over again to successively move the desired-number of blanks from the. stack.
By allowing the stack to be seated at all times either upon the blade 25 or the support 23, it will be appreciated that a minimum disarrangement of the stack takes place, in fact such disarrangement is so slight that efficient and uniform removal of the blanks is not interfered with. As the paper or other-material forming the blanks B is frequently crinkled or otherwise irregular, it is diflicult to separate the same number of blanks from the stack upon each projection of the blade 25, but when the press- .ing finger is used and the same amount of pressure applied at each operation, uniformity is secured in the number of blanks removed. If necessary a stop of conventional form maybe located on the side of the magazine opposite to the support and blade to limit the movements of the latter through said magazine.
