WALTER A. MCGARVIN, OF LOS ANGELES, CALIFORNIA, ASSIGNOR OF ONE-HALF TO FRANK DUNN AND JOHN C. DUNN, CONSTITUTING THE FIRM OF DUNN BROS., F

Los ANGELES, CALIFORNIA.

ATTACHMENT FOR PAPER J'OGGERS.

Application filed` July 16, 1924. Serial No. 726,372.

To all 'whom it may concern:

Be it known that I, WALTER A. MCGARVIN, a citizen of the United States, and a resident of Los Angeles, in the'county of Los An'- v s geles and State of California, have invented certain new and useful Improvements in Attachments for Paper Joggers, of which the following is a specification.

My invention relates to paper joggers for 1o printing presses, and in paper joggers as heretofore proposed the stock guides which are designed to jog the sheets of paper into alined position for stacking have been found to fail in their purpose because of the fact that they, being rigid and unyielding, the

jogging action is too severe, with the result that the sheets, instead of being alined, are bent or.folded at their edges and thus remain in disalined positions.

It is a purpose of my invention to provide a simple and inexpensive attachment for the conventional jogger by means of which the jogging of the paper sheets into alined position is positively insured.

It is also a purpose of my invention to provide an attachment for paper joggers which includes elements for properly guiding the sheets of paper into the j ogger as received from the press.

,I will describe only one form of attachment for paper joggers embodying my invention, and one form of conventional paper jogger, and will then point out the novel features thereof in claims.

In the accompanying drawings Figure 1 is a vertical sectional view taken on the line 1-1 of Figure 8, showing a paper jogger having applied thereto one form of attachment embodying my invenl 4o tion; Figure 2 is a top plan view of the jogger and the attachment shown in Figure 1;

Figure 3 is a view showing in endelevation the jogger and the attachment;

Figure 4 is a detail perspective view` of one of the side stock guides shown in the preceding views, and with the attachment embodying my invention applied thereto; Figure 5 isla "etail perspective view of the end stock guide shown in the preceding views, and having applied thereto another i attachment embodying my invention.

Similar reference vcharacters refer to similar parts in each of the several views of the drawing.

Referring specifically to the drawings, the conventional paper jogger is here shown as comprising a receiving table T to which the papersheets from a printing press are suco'essively delivered by means of feeding tapes F continuously movable over rollers R. The paper sheets are adapted to be stacked in vertical alinement upon the table T and as the sheets accumulate thereon the table moves step by step downwardly to accommodate the sheets, as will be understood, Above the table are three stock guides G, G and G2, which are adapted to be continuously reciprocated transversely for jogging the sheets as delivered to the table into vertically alined position.

The guide G2 consists of a supporting` formed with slots 19 to receive screw bolts` 20 by means of which an adjustment of the plates 18 with respect to the plate 15- will be effected for the purpose of increasing or decreasing the lengtlil of' the guide. As shownin Figurev 3, the plates 18 are formed withperforations 2lv through which guide Wires 22 are adapted to extend for the purpose of preventing the paper sheets as delivered from the press from flying upwardly. As shownvin Figure 1, the wires are curved rearwardly and upwardly and formed with hooked ends 22a which engage a rod 23 disposed above the feeding tapes F. The rod 16 is adapted to be reciprocated through a crank connection 23 with a shaft 24, the latter being oscillated by suitable mechanism. The rod 16 is provided with a yV-shaped cam 25 having engagement" with rollers 26 fixed on the ends of rods 27 normally urged in the direction of the cam by springs 28. -Adjustably lixed to the rods by means of clamps 29 are the guides G and G', and these guides in the present instance consist of plates 30 which are 'disposed at tion 31 serves to connect the attaching portion with the active' portion, and as the entire plate 31 is formed of resilient material it will be clear that the active portion 31b is yieldingly supported upon the plate 30. As shown in Figure 4 the attaching -portion 31 is extended rearwardly beyond the plate and curved outwardly to provide a guide plate 3ld which extends between and above the rollers R, as clearly shown in Figure 1. The two guide plates 31a co-operate to guide the paper sheetsas delivered from the feeding tapes into proper position upon the receiving table T.

The stock guide G2 is provided with members similar to the plates 31, but because of the construction of the guide member, as previously described, the members are in the form of tWo strips 32 of resilient material, and each strip comprising an attaching portion 32a, an active portion 32b and a connecting portion 32. These strips 32 are secured to the plates 18 and are designed -to function in the same manner as the plates 31.

In the operation of the jogger the stock guides in their reciprocating movement normally operate to jog the paper sheets upon the table T and into vertically alined posi-I tion, the confronting sides of the joggers having contact with the edges of the sheets in moving the latter into alined position. With the attachment in applied position to the guides they are interposed between the guides and the paper sheets so that as the guides move toward the'sheets, the active portions 31b and B2b contact with the edges of the sheets and under the movement of the guides jog the sheets into vertically alined position. By virtue of the fact that,

the active portions 31b and'32b are yieldingly supported it will be clear that during movement of the uides they yield under the pressure exerted by the guides so-as to graduate the jogging action of the guides and thus prevent bending or folding of the edges of the paper sheets, while at the same time moving the sheets into vertically alined paper joggers embodying my invention, it

is to be understood that various changes and modifications may be made herein without departing from Athe/spirit of the invention and the spirit and scope oi the appended claims.

I claim:

1. In combination, a paper jogger having stock guides, means for actuating the guides, and yieldable means adapted to be interposed between the vguides and sheets of paper to be jogged for graduating the jogging action of the guides whereby jogging of the papersheets into alined position is insured.

2. In combination, a stock guide, and a resilient member on [the lactive side of the guide, said member being adapted to yield when the guide isv moved toward the paper sheet to be jogged to graduate the jogging action of the guide,for the purpose described.

3. An attachment for stock guides comprising a member of yieldable material connected thereto, and operable to graduate the jogging action of said guides.

4. An attachment for stock guides comprising a stri of resilient material adapted to be vibrate for graduating the jogging action of the guides.

5. An attachment for stock guides comprising a member of resilient material having an attaching portion adapted to be secured contiguous to the guide, and an active portion offset with respect tothe attaching portion and spaced from the guide.

6. An attachment for stock guides comprising a member oresilient material h aving an attaching portion adapted to be secured contiguous to the guide, an active portion oliset With respect to the attaching portion and spaced from the guide, and a guiding extension projecting from onel end of the member or the purpose described.

7. An attachment for stock guides comprising a member of resilient material having an attaching portion adapted to besecured contiguous to the guide, an active portion offset with respect to the attaching portion and spaced from the guide, and a guiding-extension projecting from one end vof the member and curved outwardly.

8. In combination,v apaper jogger comprising a pair of guides spaced apart and a third guide between and at rightl angles to the first guides, and resilient members on the confronting sides of the ,guides for the purpose described.

9. In combination, a paper jogger comprising a pair of guides spaced apart and a third guide between and at right angles to the irstvguides, a resilient member on each of the first guides, and a plurality of resilient members on the third guide.

10. In combination,` a paper jogger com-4 lthe character described comprising a sheet of resilient material having vertically offset portions, and a curved extension onone of the portions.

12. An attachment for stock guides comprising a resilient member adapted for vibration in unison with the jogging action of the guides.

13. In combination, a paper jogger and stock guide, and means on sald guide adapted for vibration resultant of the jogging movement of said guides, for jogging the paper sheets into alined position.

14. In combination, a paper jogger having stock guides and means adapted for vibration by the actuation of said guides for jogging the paper sheets into alined position.
