FRANK J. BURKLEY, OF OMAHA, NEBRASKA.
Application filed July 3, 1919.
To all whom t may concern Be it known that l, FRANK J. BURKLEY, a citizen of the "United States, residing` at OmahaE in the county of Douglas and Sta-te of Nebraska, have invented certain new and useful improvements in Envelop-Feeders, of which thefollowing is a specification, reference being had therein to the accompanying drawing,
The invention relates to feeders for feeding envelope to printing presses, whereby the envelope are fed one at a time and are grasped by grippers carried by the roller, said roller carrying each envelop to a printing point where the envelops are printed.
A further object is to provide a feed er receptacle for envelope which may be adjusted to receive different sizes of envelops, also to provide said receptacle with feeding means' whereby the envelops may be picked from the receptacle one at a time by the gripping members carried by the roller.
A. further object is to provide means whereby the stack of envelope may be inclined, thereby facilitating the feeding of the same.
Vith the above and other objects in view. the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed, without departing from the spirit of the invention.
In the drawings Figure l is a side elevation of the receptacle showing the same supported above a printing roller.
Fig. 2 is a plan view of the device.
Fig. 3 is a sectional view through the receptacle and the upper portion of the feeding roller.
Referring to the drawings the numeral l designates a feed roller by means of which the envelops are fed and conveyed to the printing point7 which may be located below the roller, and 2 the gripper carried by the roller. There may be as many grippers as desired and for purposes of illustration only one gripper is shown.
Supported on bars 3 and 4, which are disposed above the roller is an envelop receptacle 5, in which receptacle envelope are deposited as clearly shown in Fig. 3. The envelops having their flaps 6 downwardly dis- Specification of Letters Patent.

posed so that as the roller revolves in the direction of the arrow a said flap will be engaged by the gripper 2 and convey-ed to the printing point.
Receptacle 5 comprises the sections 7 and 8, which sections are provided with side and front walls 9 and l0, the side walls being adapted to engage the ends of the envelops and the walls 10 are adjacent the flap edge of the envelops. Talle 10 are provided with lugs ll, which are disposed in longitudinal slots 1 2 or' the supporting oar 3. Supporting bar 4 is also provided with a longitudinal slot 13, which slot is at right angle to slots 11i in the bottoms l5 of the sections 7 and 8. Passing` through slots 14: and the slot 13 are bolts 16, by means of which bolts, the sec tions may be adjusted closer together or farther apart, thereby allowing the use of the same receptacle for different sizes of envelops. During this adjustment the lugs ll will move longitudinally in the slots l2. The forward edges of the bottoms l5 are cut away so that the gripper 2 may enter the bottom of the sections far enough so that said gripper will engage the edge of the envelop flaps. The side walls of the sections are provided with guide flanges, whereby the stack of envelops will be prevented from becoming` twisted.
Secured to the bar i as at 19 and disposed between the edges of the bottoms l5 of the sections 7 and S is a forwardly extending feed finger 21, the free end 22 of which terminates adjacent the lower end 28 of a downwardly extending spring arm 2e. Arm 24 exerts a binding action on the edges of the envelops, thereby providing means whereby the envelops will be choked and prevented from feeding too fast. Adjustable longitudinally on the linger 2l, by means of a lock bolt 25 is a triangular shaped envelop feed 26, the apex end of said feed being` adapted to be disposed below one edge of the staclr of envelope, thereby causing the edge of the envelop remote from the flap edge to be elevated so that the gripper may easily grasp the flap and pull the envelope from the receptacle at a point between the ends 22 and 23 of the finger 21 and the spring arm 24. By the inward or outward. adjustment of the member 26, it will be seen that the inclination of the envelope may be increased or diminished and the proper feeding of the envelope insured. It will also be seen that by the adjustable construction of the receptacle, that it will be possible for the same to be adjusted to receive different sizes of envelops.
The invention having been set forth, what is claimed as new and useful is An envelop feeder for printing presses comprising a receptacle, said receptacle being formed in sections, each section being supported in such a manner that they may be adjusted in relation to each for the recep tion of dierent sizes of envelops, the forward ends of said sections having their bottoms cut away, a spring` feed finger disposed between the bottoms of each section, a downwardly extending spring feed finger between the sections at their front ends, the ends of the feed lingers terminating adjacent each other, an inclined member disposed in the bottom of the receptacle, means for adjusting said inclined member for increasing or diminishing the inclination of the envelops and a gripper carried by said feed roller and so disposed as to enter the cut away portions of the bottoms of the sections to grasp an envelop flap and withdraw the envelop from the receptacle between the adjacent ends of the spring fingers.
ln testimony whereof I hereunto aliiX my signature.
