To all whom it may concern .5 I
Be it known that I, RAYMoNn L.- NARI), a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Sheet-Hold" down Attachments for F ly-Sticks, of which the following is a specification.
This invention relates to sheet hold-down attachments for fly sticks for flat bed printing presses, and has for its obgect to produce a simple, effective and inexpensive means for imposing sufficient pressure upon-each sheet laid down or stacked by the fly sticks to prevent the sheet adhering to the stlcks, as the latter start to swing back to their original positions, so that the joggers may engage and arrange the sheet in proper position upon the table or the sheets previously stacked. thereon.
To this end the invention consists in certain novel and peculiar features of construc- ,tion and organization as hereinafter described and claimed; and in order that it may be fully understood, reference is to be had to the accompanying drawing, in which Figure 1, is a vertical section of a printing press showing the sheetjreceiving table and joggers and the fly sticks, and traveling tapes for disposing printed sheets upon the fly sticks. Fig. 2, is a top plan view of the right hand half of Fig. 1. larged section on the line IIIII;I of Fig. 1. Fig. 41, is a sectional view of a bracket forming a part of each fly stick attachment.
In the said drawing, where like reference characters identify corresponding parts, 1 is a table and 2 the jogger-s thereon, the mechanism for operating the joggers being omittedas forming no part of the subject matter of this application.
Specification of Letters Patent.
Fig. 3,,is an en-' Patented Nov. 3, 1914,.
Upon each or as many of the fly. sticks as desired, I provide sheet hold-down attach- I f ments each being preferably constructedfas follows 8 is'a bracket fitting slidinglyupon a fly stick and 'provldedwith a threaded.
opening 9 wherein is mounted a clamping screw 10 for impingement upon the under v side of thefly stick to secure the bracket at the desired point thereon, and said bracket is provided witha pair of parallel perforated ea rs 11 in which are secured a pivot lr-Zfor a substantially V-shaped swinging lnthepreferred construction this swinging frame will preferably be made from a piece of wire bent at v one end to form theeye mentioned and then hentat its op'positeend to form the slot 16, the extremity of the end of the ,wire forming the slot being bent around the wire at the junction of arms and 14 thereof, v
Assuming that the parts are in the position shown by fulllines Fig.1,and that a sheet of paper. has been carried by the tapes o er the flystickait'will beseen that said sticks, as they swing upwardly, will lift such I sheet of paper from the tapes'and carry it over anddeposit it upon the table or on one or more sheets stacked thereon, thefly sticks l movingwithsuch rapidity that the swinging frames remain in the same relative position to the fly sticks in which they are'shown in full lines Fig. 1, that is to'say the fly sticks swing with such rapidity that the said frames cannot "swing ahead of them. The fly sticks swing to substantially a horizontal position and in effect lay the sheet flatly down upon the table or underlying stack.
and this is accomplished while the joggers are withdrawn from the sides of the stack so that each sheet stacked will be placed be tween the joggers. Usually considerable trouble is encountered due to the fact that each sheet stacked by the fly sticks adheres more or less to the sticks and is raised by the latter as they start to swing back to their original position, the sheets, after the sticks have movedupward a few inches on their return movement, dropping back andyfrequently falling upon the joggers which at such time have started to move inward for the purpose of disposing said sheet with its edges flush with the edges of the stack of sheets which have previously been properly arranged by the joggers. if a sheet drops down upon the joggers it must be instantly stacked or thrown aside by hand, as otherwise it will be impossible to stack the next sheet and those which follow it. 7
Where my sheet hold-down attachments are employed, they rest upon each sheet placed upon the table or stack of sheets, and retain such position until the fly sticks have traveled back in their return movement the full length of the slots 16, by which time the sheet last stacked will have become conr pletely disengaged from the fly sticks. As the fly sticks continue their return movement they carry the swinging frames with.
them, and after the fly sticks have attained their original positions the swinging frames swing downward to their original positions, so as to ofler no obstructlon to the placing of the next printed sheet upon the fly sticks.
For sheets of different size the attachments will be placed at diflerent points of adjustment along the fly sticks and for ex tremely large sheets the positions of the attachments upon the sticks may be reversed, that is to say, the blocks 8 may be secured upon and near the outer ends of the sticks with the swinging frames projecting inwardly therefrom or toward the shaft 4.
From the above description it will be apparent that I have produced sheet holddown attachments for fly sticks for printing presses which operate efliciently and reliably and which obviously may be modifled minor particulars without departing from the principle of construction involved or sacrificing any of. the advantages of the appended claims.
1. The combination with a fly stick, of a frame pivotally carried by and adapted to swing in the. same plane as the fly stick and both with and independently thereof; said frame embodying portions lying in the same vertical plane as and adapted for engagement with the fly stick for limiting independent pivotal movement of the frame with respect to the fly stick.
2. The combination with a fly stick, of a sheet hold-down attachment comprising a bracket adjustable on the fly stick, and a substantially V-shaped frame pivoted to the bracket and adapted for movement in a vertical plane, one arm of the V-shaped frame having a slot through which the fly stick loosely extends.
8. The combination with a fly stick, of a paper hold-down attachment, comprising a bracket adjustable upon the fly stick, and a swinging frame comprising a rod bent to form two arms extending at an angle to each other, one end of the rod being doubled to form a slot extending longitudinally of and for the full length of said arm; said slot receiving the fly stick;
, 4. In a sheet hold-down attachment for fly sticks, a swinging frame of V-shap'e in side view, one arm of the V-shaped frame having a longitudinal slot for its full length and the other arm terminating at its free end in an eye.
In testimony whereof, I affix my signature in presence of two wltne'sses.
