CHEEKPIEC E FOR CUTTING CYLINDER KNIVES- Filed Sept. 19, 1934 awuznkoz Patented Apr. 21, 1936 UNITED STATES PATENT OFFICE CHEEKPIECE FOR CUTTING CYLINDER NIVES Application September 19, 1934, Serial No. 744,35
3 Claims.
This invention relates to the so-called cheek pieces used to cooperate with the cutting cylinder knife in rotary newspaper folding machines.
The cheek pieces in common use are made of 5 a fibrous material, lighter in weight and of a higher frictional coeflicient than metal. The drawback in this material is a lack of resistance against impact, and the impact of the bottoms of the slots against the retaining bolts tend to break the cheek pieces at such points.
All high speed newspaper folding machines have trouble with the cheek pieces under the hammering produced by rapid operation; frequently resulting in breakage due to the hammering of the pins against the bottom of the cheek piece which causes wear and ultimately results in its splitting or cracking; another annoyance arises from the condition resultant from the contact of the hard bottom portions of the slots in the cheek piece through which knife bar bolts pass.
The objects of my invention are to obviate the aforesaid troubles and prolong the life of the cheek piece, lessen the noise of hammering produced with the ordinary cheek pieces, and obing so much trouble.
In the accompanying drawing I have illustrated two constructions of cheek pieces embodying my invention, and will explain the same with reference to said drawing and summarize in the claims the essential features of construction for which protection is desired.
In said drawing:-
Fig. 1 is a sectional view through a pair of cutting cylinders and the usual arrangement of cutting knife and cheek pieces.
Fig. 2 is a view, partly in section, showing the end to end arrangement of cheek pieces.
Fig. 3 is a view of one of my improved cheek pieces detached.
Fig. 4 is a section on the line 4-4, Fig. 3.
As shown in Fig. 1, the male cutting cylinder A carries a knife C which is mounted in a holder B between cheek pieces D, D, that are pushed outwardly by springs E; the outward movement of the cheek pieces being limited by the knife receiving bolts F which pass through slots in the cheek pieces. In operation the knife C co-acts with a cushion bar G in the female cutting cylinder H; all said parts being arranged in the usual manner.
The cheek pieces shown in Figs. 2-4 are preferably composed of a hard rubber composition or compressed fibre body I provided with the usual elongated transverse slots Ia for the passage of the knife retaining pins or bolts F, F, by which viate the breakage and splitting heretofore caus-- the cheek pieces are also retained in place in the knife holder B in the usual manner. In this construction laterally enlarged recesses ID are pro-- vided at the bottom of the slots and in these recesses are placed resilient blocks 2 of rubber or rubber composition which close the lower end of the slots. These blocks may be retained in position by means of a metal strip 3 attached to the underedge of the cheek piece by screws 30. The cheek pieces are pressed radially outward in the usual manner by springs E acting against the lower edge of the bar as shown in Fig. 2.
The strip 3 strengthens the cheek piece and provides a metal surface for the springs to press on. The strip will not give or shift or wear through; and the rubber blocks take care of the impact of high speed contact of the pins or bolts F with the bottoms of the slots Ia when, by reason of very light publications, the cheek pieces have to go farther up than usual in order to seize the paper passing between the cylinders A, H, and hold it during the cutting.
My novel cheek pieces are of light weight and move very rapidly, being alternately protruded under the expansion of the springs and retracted under the compression of contact with the paper during the cutting operation.
The up or outward motion of the cheek pieces impelled by the springs being stopped by the soft rubber at the inner ends of the slots is noiseless; and the cheek pieces are not liable to crack or break under the repeated shake of such contacts. Such cheek pieces are of very great advantage in high speed folders eliminating noise and chatter in the folder and greatly lengthening the life of the cheek pieces.
I claim:
1. A cheek piece of the character specified having guide slots for the passage of guiding pins in a knife blade, and. inserted cushions at the lower ends of the slots.
2. A cheek piece for the purpose specified having elongated slots for the passage of guide pins in a knife blade and enlarged recesses at the bases of the slots, and cushioning members secured in said recesses.
3. A cheek piece for the purpose specified having elongated slots for the passage of guide pins in a knife blade and enlarged recesses at the bases of the slots, cushioning members secured in said recesses, and a metal strip on the lower edge of the cheek piece securing the cushioning members in position.
