Application June 1, 1935, Serial No. 24,564

' 23 Claims.

My invention relates to registering devices for printing presses.

It has among its objects to provide an improved sheet receiving member for such a device and, more particularly, to provide such a member which is of an improved construction especially adapted to enable registering at high speed and in a limited space. Another object of my invention is to provide such a member having an improved spring sheet engaging member associated in a new and improved manner with the tine carried by the tine body and having improved cooperating sheet engaging portions disposed and cooperating in a new manner with one another and said first mentioned tine and also including improved connecting means connecting said sheet engaging portions and improved spring means for varying the tension of the latter, all whereby an improved cooperation and improved results are obtained. Still other objects include the provision of such a member of markedly simple construction adapted to long use in service and one which is not only exceedingly effective in operation but also small and narrow and which is moreover formed of a minimum number of simple parts of inexpensive construction and in which the tension is adapted to be readily adjusted without requiring bending of the sheet engaging portions. These and. other objects and advantages of my improved construction will, however, hereinafter more fully appear. In the accompanying drawing, I have shown for purposes of illustration one embodiment which my invention may assume inpractice.

In the drawing,-

Figure l is a top plan view of a sheet receiving member of my improved construction;

Fig. 2 is a bottom plan view of the same;

Fig. 3 is a side elevation of the same;

Fig. 4 is a longitudinal sectional view on line 4--4 of Fig. 1;

Fig. 5 is an enlarged transverse section on line 5-5 of Fig. 1;

Fig. 6 is an enlarged end view of the working end of the member shown in Fig. 1;

Fig. 7 is a top plan view of my improved spring member per se;

Fig. 8 is a bottom plan View of the member shown in Fig. 7, and

Fig. 9 is a top plan View of the tine carrying end of the cooperating tine member.

In this illustrative construction, it will be noted that I have shown a member having a usual shank l in strip form and having a usual slot 2 in one end and an elongated central time 3 at the generally indicated at 4, all as hereinafter more 5 fully described.

Referring more particularly to the member I, it will be noted that while the tine 3 has the usual flat bottom and rounded or beveled end, it' is relatively long and narrow as compared with 10 the shank and also provided with long sloping shoulders 5 connecting the same to the body of the shank I, while also provided with a rounded upper edge 6 extending from the tip along the V tine and also along the sloping shoulders 5 there- 15 on. Further, it will. be noted that between these shoulders 5 and the slot 2 an upwardly bent lug 1 is provided, herein at a point spaced from the junction of the shoulders 5 with the shank I by a distance slightly less than the distance from that 20 junction to the outer extremity of the tine 3.

Disposed on this portion of the shank l in front of the lug l is also my improved cooperating spring member 4. As shown, the same herein has a flat body portion 8 on the inner end there- 25 of and a hole 9 therein receiving a screw Ill projecting up from the shank I. It further has its body portion 8 adapted to be pressed into engagement with the shank I by an annular shoulder ll formed on a threaded and externally knurled 30 nut l2 carried on the screw [5. Also, as herein, the portion 8 is provided with a slot l3 in its rear end adapted toreceive, the lug I and thereby, in conjunction with the nut I2, position the member 4 on the shank I while the front portion of 35 the member 4 extends away from the nut I2 and along the tine 3 to cooperate with the latter.

Referring more particularly to this front portion of the member 4, it will be noted that the flat imier end of the latter is provided with an 40 upwardly bent up or inclined portion M in front ofthe nut I2 and with another flat portion I5 in front of this bent up or inclined portion l4. Further, it will be observed that in front of this flat portion I5, the member 4 is curved as at I6, 45 downward and upward to form curved marginal portions I1 extending to the end thereof. It is also provided with a central longitudinally extending raised bridging portion 18 of substantially elliptical shape in plan and of arcuate trans- 50 verse section which leads forward from the curved portion [5 between the marginal portions ll and connects the latter transversely. As shown, an upturned end flange portion I9 is also provided which formsan extension of the curve l6 and 55.

.rnarginal portions I1 and extends upward substantially above the portion 38 which merges into the base of this portion l9, while also connecting the sides of the marginal portion at the outer end thereof. Referring to the under side of the member 4, i. e., the portion of the same adjacent the tine 3, it will also be noted that the portion l8 presents a longitudinally extending groove 20 of arcuate transverse section and having on opposite sides thereof longitudinal edge portions in the form of laterally spaced sheet engaging portions 2| on the underside of the marginal portions ll. 7

When the parts are in operative relation, the tine 3 is disposed longitudinally of the groove 20, which is slightly wider than the tine, so that the latter is vertically spaced slightly from the longitudinal edge or sheet engaging portions 2|. Also, it will be noted that the tine 3 extends out in front of the groove 20 and under the portion I9, while the sheet engaging portions 2| extend longitudinally of thetine along and adjacent the opposite edges thereof over the spaces at each side of the tine 3 and extend laterally within the lateral limitsof the wider shank, these portions 2| herein being disposed wholly within the lateral limits of the latter and also being of further reduced width toward the free end of the tine, .all in such manner as thereby to minimize the dimensions of the same. Moreover, it will be observed that the sides of the tine 3 are spaced from the rounded wall portions of the groove 20, which form longitudinally extending upturned edge portions on-the inner edges of the portions 2|, so that paper receiving passages are provided between the portions 29, 2| on the resilient member 4 and the top surface of thetine 3. Attention is further directed to the fact that these passages are such that, while the inner surfaces or laterally spaced sheet engaging portions 2| on the member 4 may cooperate with the tine 3 to provide the desired grip on the paper, i. e.,

with the successive sheets above the tine 3 and below both of the portions 2 I, the sheets are prevented from passing improperly between the portions 2|, i. e., under one portion 2| and over both the tine 3 and the other portion 2|, or viceversa. Instead, the sheet is deflected and guided by the transverse connection between these portions 2|, herein the upturned end connecting portion I9, which connects these portions 2| and closesthe space between the same, in such manner asto cause the sheet to slide overthe tine andunder both portions 2| and thus to be gripped and'released by the tine 3 and portions 2| in'the desired manner. It will also be understood that this grip will be varied by suitable adjustment to adapt the device to use on papers of different thickness, while the unobstructed passage beheath the portion l5 also enables papers to extend different distances under the member 4.

As aresult of my improved construction, it is found thatextremely accurate registering is obtained, the tine member 3 and my improved member 4 cooperating effectively to provide the requisite grip on the paper to carry it over to the side guide at high speed. Further, as a result of my improved construction, it is found that a very desirable gradual release of the paper is effected as the sheet receiving member moves to disengage the sheets, the portions 2| which engage the sheets on opposite sides of the tine 3, successively disengaging from the sheet as the member 4 swings. Moreover, my improved construction, in addition to a minimum width heretofore unobtainable while producing a construction making possible the use of the markedly advantageous laterally spaced sheet engaging portions cooperating with a central tine, also has the marked advantage over prior devices having lat- 5 erally spaced cooperating sheet engaging portions in the form of prongs, of preventing the passage of a sheet under either sheet engaging portion and over both the central tine and the other sheet engaging portion and thus eliminates resultant difri- 10 culties including delays, spoilage of sheets and breakage. Attention is further directed to the fact that the member 4 is so narrow and compact that it clears in thedesired manner when swung to disengaging position in a very limited space and 15 thus avoids the breakage and delays incident to the use of such wide prior structures as shown in the Klorer patent, No. 1,330,636, which will not clear in certain presses. Further attention is directed to the markedly simple and inexpensive 20 character of my improved construction as compared with a construction of the Klorer type, and, particularly, totheimproved construction of my improved spring member 4 and'the improvedaction on the sheets made possible' with the same: 25 in combination with my improved shank tine" member. It is also found that my improved structure is adapted to stand up well in service and to continue to function effectively over long periods while permitting the-use of thin material. it will be notedthat it is possible to adjust the. tension as necessary by merely bending the mem ber 4 at the portion l4, any necessity for bending atthe front end of the member 4 which may derange feeding, being wholly avoided. also be understood that the raised portion l8- may be cut out in whole or in part if desired without interfering with the eifective operation of the device under certain conditions, although such a construction isnot. preferred and the 40,-

structure is weakened-thereby while" heavier ma-- terial for the rest of the member 4 isalso thus made necessary. Theseand other advantages of my improved construction will, however, be clearly'apparent to those skilled in the 'art. 45 While I have inthis application specifically described one form'which my invention may assume in practice, itlwill be understood that this form is used for purposes of illustration and that the invention is not limitedthereto and may be 50 modifiedand embodied in other forms without departing from itsspirit or the scope of the appended claims.
