ROBERT J. THOMPSON, OF HARRISBURG, PENNSYLVANIA, AND RAYMOND S. DALTON, OF CLEVELAND, OHIO, ASSIGNORS OF ONE-HALF TO THE CLEVELAND FOLDING MACHINE COMPANY, OF CLEVELAND. OHIO, CORPORATION OF OHIO, AND ONE- HALF TO THE W. O. 'HICKOK MANUFACTURING COMPANY, OF HARRISBURG, PENN- SYLVANIA, A CORPORATION OF PENNSYLVANIA.
PAPER-FEEDING ATPPARA'I'I'J'S.
Application filed September 27, 1921. A Serial No. 503,659.
T all whom it may concern:
Be it known that we. Roman J. THOMP- SON and RAYMOND S. DAmoN, citizens of the United States, residing at Harrisburg and Cleveland. respectively, in. the county of Dauphin and State of Pennsylvania and in thecounty of Cuyahoga and State of,
Ohio, have invented: certain newand useful Improvements in Paper-Feeding Apparatus, of which the following is a specification.
As is well known by those skilled in the art in paper-feeding apparatus an air blast is utilized in onetype of device for separat-.
ing the upper sheets of the pile prior to their belng successively passed into the ruling or other apparatus. \Vhere the sheetsare long and narrow, difficulty has been experienced due to the fact that the air blast delivered at '20 the front end of the pile will not pass between the sheets longitudinally thereof. but seeking the path of least resistance, will escape at the side edges and as a consequence, a proper separation will not occur. It is the object of the present invention to provide means that will insure the retention of the air between the sheets and secure its passage from one end of the pile to the other.
In the accompanying drawings Figure 1 is a vertical longitudinal sectional view through a portion of a feeding apparatus, showing the improvement in P Fig. 2 is a cross-sectional view at righ angles to Fig. 1;
Fig. 3 is a horizontal sectional view on the line 3-3 of Fig. 1.
Only suflicient of a paper feeding apparatus is shown to illustrate the location and application of the improvements.
The usual table is designated 4 on which a ile of sheets to be fed is placed, the pile being shown at 5. A nozzle 6, illustrated in Fig. 1, is utilized to deliver a blast of air a ainst the upper portion of the front end 0% the pile 5. So far as thus disclosed. the up aratus is well known. I
A cross bar 7 is suitably supported over the table 4 and pile 5 in spaced relation to the top of the latter and slidably mounted thereon on collars 8 that may be held at any desired points by setscrews 9. The collars 8 are provided with vertical eyesv 10 through which are slidably passed vertical hangers 1 1. These hangers are preferably in the form of rods having key\vays l2 and the eyes 10 support keys 13 engaged in said keyways. The hanger rods 11 are preferably threaded and. screwedonv their upper ends are adjusting nuts 14 that bear upon the tops of; the eyes 10. .The hangerrods 11 have secured to theirlowcr-ends angle strips 15-, the depending flanges of which. have their lower-margins preferably outturned. as shownat 16.
As will be clear particularly by reference toFig. 2. the-angle plates are placed over the upper side marginsof the pile 5 and are so positioned that they will allow the necessary play of the sheets. Therefore, when the blast of air is delivered from the nozzle 6 against the upper portion of the rear end of the pile, the air will pass between the uppermost sheets of the pile and will be prevented from escaping freely at the side edges. It will, therefore. necessarily traverse the pile to the front end and consequently will insure the proper separation of the sheets. Obviously the mountings of the strips 15 permit their vertical and lateral adjustment so that they may be fitted to piles of different sizes and shapes.
From the foregoing it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art. without further description, and it will be understood that various changes in the size. shape, proportion. and minor details of construction. may be resorted to without departing from the spirit or sacrificing any of the advantages of the herein described invention.
Having thus described our invention. What we claim as new and desire to secure by" Letters Patent, is
1. In paper feeding apparatus. the combination with means for supporting a ile of paper and means for delivering a b ast of air against one end of the same, of means for preventing the free escape of the air so delivered from the lateral sides of the pile. said air delivering means and air escape preventing means permitting the free.-
edgewise removal of the topmost sheets from the pile;
2. In paper feeding apparatus, the combination with means for supporting a )ile of paper and means for delivering a blast of air "adjacent one end of the same. of air retaining walls that extend alongside of the pile to prevent the free escape of the air thereIrom said walls having an unobstructed space between their ends to permit the edgewise movement of the sheets from the pile, and means for supporting-said walls.
3. In paper feeding apparatus, the combination with means for supporting a pile of paper andmeans for delivering a blast of air adjacent one end of the same, of air retaining angle strips that overlie the side margins of the pile and extend. along the sides thereof.
4. In paper. feeding apparatus, the combi nation with means for supporting a pile of paper and means for dehvering a blast of air adjacent one end of the same, of air retaining walls that extend alongside of the pile to prevent the free escape of the air therefrom, and adjustable hangers for supporting said Walls.
5. In paper feeding apparatus, the combination with a table for supporting a pile of sheets, of means for delivering an air blast to one end of a pile placed on said table, a cross bar extending across said table above the same. hangers adjust-ably mounted on said cross bar. and angle strips carried by said hangers. said strips overlying the side margins of the pile and enclosing the side edges thereof.
(3. In paper feeding apparatus, the combination with a table for supporting a )ile of paper, and means for delivering a biast of air against one end of the same. of spaced devices for preventing the free escape of the air so delivered from the lateral sides of the pile while permitting the edgewise removal of the sheets from between said devices, and means independent of the pile supporting table for supporting said devices.
In testimony whereof. we affix our signatures in the presence of two Witnesses.
