FRANCIS H. RICHARDS, OF CLEVELAND, OHIO.
ENVELOPE-FOLDING MECHANISM.
SPECIFICATION forming part of Letters Patent No. 296,353, dated April 8, 1884:.
Application filed March 29, 1883. (N0 model.)
To @513 whom it may concern:
Be it known that I, FRANCIS H. RICHARDS, acitizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain Improvements in Envelope-Folding Mechanism, of which the following is a specification.
My invention relates, chiefly, to certain improvements for operating the folding-wings of the usual forms of envelope-maohines-as, for instance, those of that form thereof shown in Letters Patent No. 58,327, granted to T. V. Waymouth September 25, 1866, to the construction and operation of the bottom part of the box of such folding mechanisms, andto means for delivering the folded envelopes to the endless apron or other device for holding them until the gum on the seal-flap is dry.
In the accompanying drawings, in which the views are made in projection the better to illustrate the form and arrangement of the parts, Figure l is an end elevation, partially in section. Fig. 2 is a front view of a portion of the mechanism, also partially in section; and Fig. 3 is a plan, also partially in section.
In Figs. 1 and 2 the folding-wings are shown in an open position, and in Fig. 3 they are shown closed, the top of box 13 being broken away the better to show them. In Fig. 3 the devices for actuating the folding-wings are mostly hid from View by the table A of the machine.
Similar letters refer to similar parts through out all the views.
lfhe table of the machine A is provided with the box B, of the usual form, having foldingwings a a b 9, also of the usual description, and operating to fold the envelope in the usual manner. lhese folding-wings are supported upon shafts rigidly fixed therein, and herein considered and referred to as integral therewith. The arrangement of the said shaft is best seen in Fig. 3.
In addition to the usual drivingshaft of the envelope-machine, I employ a shaft, S, arranged to have preferably a continuous rotary motion uniformly with the said drivingshaft, and to carry the several cams O G G G", for operating the folding-wings. A series of plates, 2, adapted to have envelopes'folded thereon, are in the present instance arranged to be revolved about and by shaft S between cams C O by means of friction- washers 7 and 8 acting upon the opposite sides of web V, upon which the said plates 1. are formed or secured. v
H is a stop arranged to operate to arrest the motion of plates 15 at the proper time and place for envelopes to beformed thereonin the present instance by a sliding motion imparted thereto by suitable connections with the driving mechanism of the machine. (Not shown in the drawings.) An endless apron, d, suitably operated, and of the usual or any suitable form, is employed to receive the folded envelopes and retain them until the gum on the seal-flap is dry, and it is so placed as to receive the envelopes directly from the plate 15, preferably in position 2, as hereinafter described, and without the assistance of the usual guides.
D is a wiping-roll, brush, or other device equivalent thereto, suitably driven, and supported in the present instance by a swinging arm, E, Fig. l, pivoted at 11, and retained in proper position by stop 10 and spring 9.
The cams G O are made alike, or nearly so, and rigidly fixed upon shaft S in reversed positions, corresponding to the reversed positions of wings a a, as shown in Fig. 2. The cams O are made concave, as shown, and provided with spiral cam-grooves w in their concave surfaces. By employing a cam of this description for the purpose and in the manner shown, all connections intermediate to the cam and the arm of the said folding-wing are avoided, thereby securing the utmost certainty of operation, and so simplifying the machine as to render the other mech auisms thereof much more accessible.
Cams 0 and 0 (shown in side view in Fig. 2) are shown in the present instance of such peripheral outline as to impart the desired motions to close wings b and g, respectively, by means of arms 5 and 6, the return motion of the said wings being effected by springs or their equivalent. (Not shown in the drawings.)
The operation of my improved envelopefolding mechanism is as follows: The envelopeblankhaving been delivered upon box B and driven down by the creasing-plunger upon the plate t, forming the bottom of said box in position 1, the rotary motion of cams O O operates, by means of grooves w and arms h, to close the end-folding wings a a, and in proper order cam 0 by means of arm 6, closes backfolding wing g, and cam G, by means of arm 5, closes seal-flap-folding wing b. The further motion of shaft S and its cams now returns the folding-wings a a to their original positions, the wings b 9 being returned to their corresponding positions by means of springs (not shown) or their equivalent, and thestop Hbeing then withdrawn by connections (not shown) allows the shaft S, by means of the frictionwashers 7 and 8, to rotate the web 1;, with the plates t thereon, until the plate if from position 1, having the folded envelope thereon,
reaches position 2, when a reverse motion of stop H arrests the motion of plates t, and the envelope e falls from the plate then at 2 into space 0 of the endless apron d. During the interval of rotation of the plates 25, that one passing from position 3 to position 4 is operated upon by a suitably-constructed wiper, D, to remove from the surface thereof any extraneous matter before it reaches the position to again have folded thereon another envelope.
For the purpose of retaining the folded envelope upon the plate t during its passage from position 1 to position 2, the said plates areformedwithsuitableperforations orgrooves in their surface and passages u,which, during the rotation thereof, communicate with a passage, t, in shaft S, in which a sufficient vacuum is formed for that purpose. The passage t is so formed and located in shaft S that its communication with passage to of the plate then forming the bottom of box B will be made immediately before the commencement of and continue during the rotation of the said plate It. When the motion of the plate 15 is arrested, the shaft S, by continuing its rotation, closes the communication of passage with passage u, whereby the vacuum therein is de stroyed and the folded envelope allowed to fall into space 0 of endless apron d. To insure the prompt delivery of the envelope from the plate at position 2 into space 0, there is provided a finger, f, Fig. 1, adapted to be moved by suitable mechanism (not shown in the drawings) in frontof plate 25, to knock the envelope 6 therefrom.
The finger f is shown in the drawings pivotally supported; but that construction is not essential to its purpose.
I do not limit myself to the use of a series of plates with surfaces adapted to have envelopes folded thereon, and parallel to the axis of shaft S, as herein shown and described; but
the said series of plates may be arranged to be rotated about avertical or inclined axis, or to be moved into position horizontally, or arranged in a chain or belt form, or otherwise, as may be preferred. The firstnamed arrangement, being the one shown in the drawings, is, however, believed to be most "desirable, and is therefore selected to illustrate my invention.
For the purpose of keeping the surface of plates t free from extraneous matter, I do not limit myself to a roll or brush, D, arranged to operate by rotation only, as I am aware that a belt of various materials, also arrangements of reciprocating brushes or other wipers, can be employed.
The shaft S is herein described as having a continuous rotary motion, that being considered most desirable; but it is obvious that a reciprocating rotary motion thereof may be employed. In, thatcase the plates 16 can be driven by a ratchet and pawl directly therefrom without the aid of friction-surfaces. The said plates may also be driven by direct independent connections with the principal shaft or other mechanism of the machine by wellknown devices.
The number of plates 15 in the series may be two or more; but four are believed most advantageous. They may be provided with the usual adjustable periphery for governing the thickness of the envelopes.
