I UNITED STATES PATENT orrion. EDWARD ERMOLD, OF NEW YORK, N. 'Y.

ENVELOP-MACHINE.

Specification of Letters Patent.

Patented Dec, 12, 1905.

1'0 all whom it may concern:

Be it known that I, EDWARD ERMOLD, a citizen of the United States, residing in New York, borough of Manhattan, in the State of New York, have invented certain new and useful Improvements in Envelop-Machines, of which the following is a specification.

It is well known that when transferring the paste from the paste-roller ofthe envelop-machines to the flaps of envelop-blanks a number of envelops receive more than the required quantity of the adhesive material when the elevator on which the pile of blanks is supported is raised again after placing a new pile of envelop-blanks thereon, as during the time required for lowering the elevator and placing a new pile thereon the paste-roller continues its reciprocating motion and takes up a too large quantity of paste without being able to transfer the same in the regular manner to the envelop-blanks. When the elevator is returned with a pile of blanks, the blanks on top of the pile receive then an extra quantity of paste from the roller. This objectionable transfer of the surplus paste to the blanks continues until the quantity of paste on the pasteroller is diminished and the paste-roller restored to its normal condition, so that the transfer of the paste to the flaps can then again take place in the regular manner. The extra quantity of paste transferred to the flaps necessitates the rejection of a number of the envelops as defective.

the motion of the paste-roller is again auto-.

matically interrupted, when the pile of envelop-blanks is again exhausted; and for this purpose the invention consists of an envelopmachine in which the paste-roller is combined with means for automatically interrupting the reciprocating motion of the same when the pile of blanks fed to the pickers becomes gradually exhausted, so that the taking up of paste by the roller is temporarily interrupted.

The invention consists, further, of means for automatically starting the motion of the paste-transferring roller at the proper time.

after a new pile of blanks is supplied to the elevator, and the invention consists, lastly, of certain additional features and details of com struction by which these objects are carried out, which details will be fully described heretail of a portion of the mechanism for transmitting motion to the knocker-pin. Fig. 3 is also a detail, partly in vertical transverse section on line 3 3, Fig. 1, of the stop mechanism for the paste-roller. Fig. 4 is a detail front view of the mechanism for interrupting the reciprocating motion of the paste-roller drawn on a larger scale. Fig. 5 is a plan view of Fig. 4. Fig. 6 is a vertical longitudinal section on line 6 6, Fig. 5. Fig. 7 is a detail front elevation of the latch for locking the stop mechanism of the paste-roller. Fig. 8 is a detail plan view of the actuating-lever of the stop mechanism for the paste-roller. Fig. 9 is a detail vertical transverse section on line 9 9, Fig. 4, of the clutch mechanism connected with the motion-transmitting mechanism of the paste-roller for interrupting the motion of the same; and Fig. 10 is a side elevation, partly in section, through the knockerpin of the stop mechanism for the paste-roller.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the supporting-frame of my improved envelopmachine, and A the table supported thereon. On the table A is supported the upper frame A on which the pickers P, folders, and other operative parts of the envelopmachine are supported. To the upper frame A are attached transverse yokes A which support two parallel rods a, on which are guided the sleeves a, from which the reciprocating pasteroller B is suspended. The shaft of the pasteroller B is supported in hook-shaped bearings (0 which are suspended from the sleeves a).

The paste roller B takes up the paste by contact with feed-rolls b, which are located in a paste-receptacle B, that is supported on the upper frame A the rolls 6 and the paste-receptacle being of the usual well-known construction. Below the reciprocating pasteroller B is arranged in an opening of the ta-v ble A the platform E of the elevator E by which the envelop-blanks are fed to the pickers, the elevator being raised or lowered by the well-known rack-and-pinion mechanism. The shaft of the pinion is provided at its front end with a hand-wheel for raising or lowering the elevator by hand whenever necessary. Reciprocating motion is imparted to the paste-roller B by a motion-transmitting mechanism from a cam-shaft S, which is located in bearings at the lower part of the main frame A and rotated by a gear-wheel transmission g g from a driving-shaft S in the usual manner. On the gear-wheel g is located a cam g the cam-groove of which engages an antifriction-roller g which is applied to a verticallyreciprocating rod 1", that is guided in a keeper 7", provided below the roller g with aforked end r so as to move along the cam-shaft 8. To the vertically-reciprocating rod 1- is pivoted the lower end of a'connecting-rod T the upper end of which is adjustably pivoted to the lower arm of a fulcrumed elbow-lever 9*, which is fulcrumed to a bracket P, that is attached to the main frame A. The upper arm of the elbow-leverr is provided with atoothed segment 1", that engages a pinion r, the shaft 1" of which is supported in hanger-bearings r said pinion-shaft being mounted at both ends with reciprocating lever-arms 7 which are againconnected at their upper ends by pivoted connecting-rods 7" with lugs r on the sliding sleeves to, from which the paste-roller B is suspended. The cam-groove g is so shaped that by the intermediate mechanism described the paste-roller B is reciprocated on its guide-rods a, said motion being timed in such a manner that the paste is imparted to the pickers P and transferred from the same to the flaps of the envelop-blanks before they are folded by the folding mechanism. The mechanism by which reciprocating motion is imparted to the paste-roller B is well known and forms no part of the present invention.

The novel feature consists in the mechanism by which the motion of the paste-roller B is temporarily interrupted and the same arrested at the opposite end of its stroke, so as to prevent the transfer of the paste from the paste-transferring roll 6 to the pickers P when a new pile of envelop-blanks is placed on the elevator-platform E. For this purpose the arms of the elbow-lever r are not made in one piece, but separated from each other, the hub of the lower arm being placed on the hub of the upper arm, as shown in Fig. '9, so as to be locked together or released from each other by a clutch mechanism. The upper arm of the elbow-lever r is supported on a shaft d, which is supported in a block d on the bracket T The hub (Z of the upper arm of the elbow-lever r is placed loosely on the shaft d and held against the front shoulder of a middle enlarged portion 0Z of the shaft by a head (i at the front end of the shaft, while the rear end is attached by a screw-nut 0Z to the stationary block d. The block CZ, abuts against the rear shoulder of the intermediate enlarged portion 0Z The hub (Z6 of the lower arm of the elbow-lever 1' is provided with three holes 0Z which are adapted to be engaged by a corresponding number of clutch-pins d that are attached to the circumferential flange of a clutch 01, that is placed slidably on the enlarged portion (Z of the shaft d. The clutch d is held against the hub of the upper arm of the elbow-leverr by means of spring-actuated pins d, that are guidedin holes of the stationary block at. The clutch d is provided with a circumferential groove 6, that is engaged by inwardly-projectiugpins e of the ring-shaped portion 6 of a clutch-operating lever D, which is fulcrumed to a supporting-bracket (a attached to the frame A. The fulcrum d" of a clutch-operating lever D is carried by a keeper 0, which turns in the bracket 6 so that the lever D can be oscillated in a horizontal as well as in a vertical direction. The outer end of the clutch-operating lever D is connected by a helical spring 6 with a suitable support a on the frame A, so as to be drawn in downward direction in the slot of the bracket 0 The outer end of the leverD is further provided with a rearwardly-projecting lug 6 that is intermittently placed in the path of an oscillating rocker-pin f, which is guided in a socket f, the rocker-pin being actuated by ahelical spring f which is placed on the shank of the rocker-pin and interposed between the head of the pin and the upper end of the socket, as shown clearly in Fig. 10. The socket f is supported on the upper arm of a rocking elbow-lever f which is fulcrumed to the frame A, while the lower arm of the elbow-lever f is connected by a rod f, having a forked lower end 1, as shown in Fig. 2*, with a cam f on the cam-shaft S, the cam f acting on a roller f on the forked lower end of the rod f so that'the rockerpin f is intermittently oscillated by the cam f and the intermediate mechanism for engaging the lug e at the outer end of the clutch-lever D when the same is placed in the path of the rocker-pin f.

To the upper part of the bracket 9" is applied a short arm h, which extends at right angles to the bracket in forward direction and which serves to engage a recessed keeper it, that is attached to the flange of the laterally-slidable clutch 0Z so as to interlock with the same when the clutch d is shifted against the pressure of the pins 0Z and produce thereby the locking of the clutch-lever D in position, so as to be acted upon by the rockersome;

pin. To the opposite or inner end of the "clutch-lever D, adjacent to the ring-shaped portion of the same, is attached a curved horizontal arm g, which is provided with a recess g adjacent the lever D and which extends backwardly through an opening in the bracket W, as shown in Figs. t and 5. To the bracket 'r is fulcrumed a spring-actuated latch 9 position shown in full lines in Fig. 8 to that shown in dotted lines in the same figure, so

that the latch engages the recess 9 and locks thereby the arm 9 and the clutch-lever D alongside of the bracket W, as shown in Figs. 6 and 7 The latch g is provided with a downwardly-extending nose-piece g which extends at an obtuse angle to the shank of the latch and which in the locked position of the latch is placed in the path of the inclined face on the curved lower end of an arm E ,that is attached to the under side of the elevatorplatform E, so that on the raising and lower ing of the elevator and its platform the lower end of the arm forms contact with the nose 9 of the latch g presses on the same, and moves the latch on its fulcrum against the tension of it's spring, so as to release it from the recessed arm g and permit thereby the return of the clutch-lever D into the position shown in full lines in Figs. 5 and 8. While the clutch-lever D is placed in locked position, the sliding clutch d is moved on the enlarged portion d of the shaft-din backward direction against the tension of the pins 03 so as to withdraw theclutch-pins 0Z from the holes (2 in the hub or the lower arm of the el bow-lever r, so that no oscillating motion can be transmitted to the'upper arm of the elbow-lever T The reciprocatingmotion of the paste-roller is therethe lower arm and impart reciprocating motion to the paste-roller B, so that paste is again transmitted by the same to the face of the pickers.

The arm E is attached to the under side of the platform E in such a manner as to permit its proper adjustment relatively to the latch of the same.

to be operated thereby.- It is provided at its middle portion with a curved bracket E to which is pivoted a heel c', the shank of which moves between two pins 2", one at each side The lower straight part of the heel c' is placed in the path of the inner end of the lever D whenthe same is in its normal position and clears the same by swinging side- As soon aswise on its pivot when the platform E and arm E are moved in upward direction, but producing the engagement of the heel 71 with the end of the lever D by the downward motionof the elevator-platform, so that the outer end of the clutch-lever is raised and placed into the path of the rocker-pin f, so that the side of the latter engages the same in the manner shown in Fig. 6, and horizontal motion is thereby imparted to the clutch-lever and the clutch d shifted out of operative position. Said lever is then locked by the latch 9 so that the attendant can place a new pile of envelop-blanks on the elevator-platform E, while the motion of the paste-roller B is interrupted. By then raising the elevator the curved lowerend of the arm E engages the nose of the latch g and releases it from the arm g on the clutch-lever D, so that the latter is instantly returned into its normal position, so as to cause the locking together of the arms of the elbow-lever r, and thereby-the instant resumption of the motion of the paste-roller and the transfer of paste to the envelop-blanks of the new pile. The upward motion of the elevator produces, by the releasing of the clutchlever D by the lower end of the arm E the automatic interruption of the reciprocating motion of the paste-roller, while the automatic dropping of the elevator produces the engagement of the heel 21 on the arm E with the lever D, the relocking of the clutch-lever, and thereby the restarting of the reciprocating motion of the paste-roller. When the pile of blanks on the elevator-platform is sufliciently reduced in size so that a new pile has to be supplied, the elevator is automatically dropped in the usual manner and produces, by the action of the heel c' on the clutch-lever D, the locking of the clutch-lever D and the interruption of the reciprocating motion of the paste-roller until a new pile of blanks is placed on the elevator and the same raised in position, so that the uppermost blank is below the pickers. During the upward motion of the elevator the lower end of the arm E releases the latch and produces the instant return of the clutch-lever and clutch into engagement with the operating mechanism of the pasteroller, so that the latter resumes its motion and transfers paste to the pickers, the setting of the clutch mechanism by which the motion of the paste-roller is interrupted or established being accomplished by the automatic lowering and raising of the elevator and the action of the heel and curved arm on'the elevatorplatform, on the clutch-lever, and the clutch mechanism operated thereby.

The advantage of my improved attachment for envelop-machines is that the reciprocating intermittently interrupted when the same is ,motion of the paste-roller is automatically and I not required for transmitting paste from the paste-receptacle to the pickers and that its reciprocating motion is reestablished when a new pile of blanks is placed on the elevatorplatform and the regular motion of the envelop machine reestablished, whereby the transfer of surplus paste to the face of the pickers, the overgumming of the envelop-flaps, and the waste of envelops in consequence thereof is obviated and the uniform gumming of the flaps of the blanks, and thereby the more efficient working of the paste-supply mechanism of the envelop-machine, obtained.
