Application filed October 27, 1916. Serial No. 128,033.

To all whomz't mag concern: f

Be it known that I, SAMUEL *FURMAN, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Patch-Applying Mechanism in Machines for Making NVindow- Envelop Blanks, of which the following is a specification accompanied by drawings forming a part of the same, in which Figure 1 represents a side view of so much of a machine for making window envelop blanks as is necessary to illustrate the nature and operation of my present invention with one side of the frame removed for the purpose of clearness.

Fig. 2 is an end view of the same looking from the left.

Similar reference figures refer to similar parts in the difierent views.

My present invention relates to that portion of the mechanism of a window envelop making machine which is directly concerned in applying the patch to an opening in the body of an envelop blank.

The mechanism embodying my present invention is designed to 'be operated in connection with the window cutting and gumming mechanisms of a machine for making window envelop blanks, on which Letters Patent of the United States No. 1,182,364

' was granted to me May 9th, 1916.

The envelop blank when presented to the mechanism for applying the patch, has an opening formed therein, and gum applied to the margin of said opening and is ready to receive a transparent patch to cover said opening.

Referring more particularly to the parts;

1 are the side frames of the machine in which all of the shafts are journaled.

2 is a shaft to which the patch carrier 3is fastened and also the stationary cams 4' are loosely fitted on said shaft.

5 is the shaft of the blank bed .5? and the lower ends of forks 6'are loosely fitted on said shaft. The upper ends of said forks are fastened to cams 4 thereby preventing said cams from turning on shaft 2.

7 is a bar connected to patch carrier 3 and radially slidable therein. Each end of said bar extends some distance out of said carrier er s id s ionary a s Ant Specificacion of Letters Batent.

on MAKING WINDOW-ENVELOP Patented. Oct. 7, 1919.

"friction rollers 8 are fitted on each end of "said bar and in contact with stationary cams 4. v y

. ,9' are pins" mounted on the slidable bar 7 and sliding therewith in the body of the patch carrier 3.

The cams 4 are designed of such a shape as to move said bar to and from the center of rotation of said carrier thereby moving said pins 9, which are connected to the said bar, out of said carrier when in contact with segments or rollers 10, to meet and enter the openings 10* in said segments or rollers for the purpose of engaging a patch thereon and recede into said carrier 3 when coming in contact with the blank bed 5 thereby releasing said patch and applying it to a margin of the opening in the envelop blank.

11 are springs. One end of each spring is fastened to sliding bar 7 and the other ends to the shaft 2 thus tending to keep cam rollers 8 which are on sliding bar 7 in contact with stationary cams 4, so as to transmit the sliding motion to said pins 9 in said carrier 3.

12 is the roll of transparent paper, the

- free ends of which is fed into the machine by means of roller 13 on shaft 14, and the roller 15 the ends of which are journaled in'frame 1. Any suitable mechanism, not shown, can be employed for operating the feed rollers 14 and 15 intermittently to feed the patches singly upon the patch support 18 in proper time to be transferred by the segments 10 to the patch carrier 3.

16 is a stationary knife and 17 is the movable knife for cutting patches of a proper width from the web which is fed y the rolls 13 and 15.

18 is a supporting table for said patches to rest on preliminary to their being engaged by the slidable pins 9.

' The various rollers and the patch carrier tion. as indicated by the arrow. 1

Having thus described my invention, I claim and desire to secure by Letters Patent:

1. In a patch applying mechanism of an envelop machine, a framework, a rotatable shaft'journaled thereon, a patch carrying roll on said haf cams held.- ocse y a d- 3 are driven by means of gears in the direcshaft at each end of said patch carrying roll, means for holding said cams from rotation, a bar radially movable in said patch carrying roll and projecting beyond its ends, rolls journaled on the ends of said bar in contact With said cams, and means carried by said bar for engaging a patch.

2. In a patch applying mechanism of an envelop machine, a framework, a rotatable shaft journaled therein, a patch carrying roll held on said shaft, means carried by said patch carrying roll for engaging a patch, means for actuating said patch engaging means to engage a patch, comprising cams held loosely on" said shaft at each end of the patch carrying roll, means for h0ld ing said cams from rotation, and a bed roll running in contact with said patch carrying roll for applying pressure to the patch as it is carried between said rolls, and means for reversing said patch engaging means to release the patch.
