SPECIFICATION forming part of Letters Patent No. 771,998, dated October 11, 1904.

Application filed February 12, 1902. Serial No. 93,810. (No model.)

To all whOm it may concern.-

Be it known that I, ROBERT F. P1oK,a subject of His Majesty Edward VII, King of Great Britain, residing in the city of New York, borough of Manhattan, State of New York, have inventela new and useful Machine for the Application, Distribution, and Spreading of Paste or other Adhesive Substance Upon and Over Envelops or Wrappers, of which the following is a specification. My invention relates to a machine for the application, distribution, and spreading of paste or other adhesive substance upon and over envelops or wrappers by means of a weight or roller set or placed immediately in front of the aperture from which the said paste or other adhesive substance flows; and the objects of my invention are, first, to apply, distribute, and spread said paste or other adhesive substance evenly and uniformly upon and over the said envelops or wrappers; second, to prevent the said paste or other adhesive substance from flowing or spreading beyond the desired point; third, to hold said wrappers or envelops in proper place or position to receive said paste or other adhesive substance; fourth, to produce a simple apparatus which shall be more convenient and efficient in manipulation and operation than machines heretofore used. I attain these objects by means of the mechanism illustrated in the accompanying drawings, in which Figure I is a longitudinal section of the part of the machine sought to be patented. Fig. II is a top plan of same. Fig. III is a longitudinal section of the well or receptacle in which the paste or other adhesive substance is contained. Fig. IV is atop plan of said well or receptacle. Fig. V is a longitudinal section showing the device for cutting ofi or discontinuing the flow of the paste or other adhesive substance when desired. Fig. VI is a top view of the last-mentioned device.

Similar letters refer to similar parts throughout .the several views.

The inclined plane or table a, secured to the upright b, constitutes the frame of the machine, upon which the various parts are built. The arms 0 are attached to the upright b at d in such a manner as to provide a perpendicular motion, and at the end of said arms 0 at e are inserted axles or rods carrying a roller f, as shown in Figs. I and II', said roller being preferably so constructed as to turn freely upon its axis and resting upon the envelops or wrappers, thus constituting a means for evenly spreading the paste and limiting its flow from the well.

it, as shown in Figs. I and II, is a slightlyinclined plate attached to the table a, upon which the ends of the wrappers or envelops g sought to be pasted repose. The inclined face of this plate not only facilitates the withdrawal of the wrappers or envelops from under the well 2'- 2' z' vi and the roller f, but also tends to cause the paste or other adhesive substance to flow from the said well toward the rollerf and out, upon, and over the ends of the wrappers or envelops g. M represent the said well or receptacle. This well is supported by the arms 0, upon which it preferably rests, at the points k whenthe sheets are exhausted as well as when the arms are raised. The front portion of the well extends laterally beyond the body of the well on each side to such an extent as to project partially over the arms 0 0, so as not only to rest thereon at the points 71? Z: when the sheets are exhausted, but to be lifted thereby when the arms 0 0 are raised. This well is maintained in its proper position relative to the wrappers or envelops by the upright Z, the same being securely attached to the table a, as shown in Fig. I. The rear face or wall of said well i is so extended up, down, and over the upright Z as to readily and easily fit over the same, as shown in Fig. I, and is so adjusted that the bottom of the well rests upon the wrappers 9 when the roller rests on the top of a pile of sheets, as shown in Fig. I. Along the entire length of the bottom of the front edge of the well facing the roller extends an aperture m, through which the paste or other adhesive substance flows out, over, and upon the wrappers or envelops and toward the roller f, as shown in Fig. I. Thereupon and as each wrapper is withdrawn by the operator the roller f, by virtue of its weight and position, spreads the paste or other adhesive substance evenly and uniformly upon and over the end of each wrapper or envelop and also prevents the flow of said paste or other adhesive sub stance beyond the point at which the said roller rests upon said wrappers or envelops.

n represents a rectangular standard or upright attached, as shown in Fig. II, to the table a, which, in connection with the standard or upright Z, acts as a guide to keep the wrappers or envelops in the proper position to receive the'paste.

0 represents a transverse brace connecting the arms 0, as shown in Figs. I and II.

19 represents the legs attached at q to the arms 0, which legs support the said arms and the structure resting thereon when the same is raised for the purpose of inserting a fresh supply of wrappers or envelops.

s, in Fig. IV, represents an inner well entirely separate and detachable from the machine, which when in use may be set into the outer or main well i. This inner well conforms in shape to the outer well, exactly fitting therein, and consists of three sides and a bottom and is open as to the inner end. The bottom of this inner well contains no aperture and is materially shorter than the outer or main well and may be moved from one end to the other of the said main well and adjusted, by means of the binding-screwy, at any desired point. Fig. III shows a longitudinal section of the said main well with the said inner well set therein, and when so used the aperture m in the said main well is closed by the said inner well. By this device the pastingsurface or pasting length of the well may be reduced to any desired width or extended to the full pasting surface or width of the main Well. When desired to entirely discontinue the flow of the paste, the rectangular piece of metal 25 (shown in Figs. V and V1) may be placed under the well 2' and the roller f and -on top of the wrappers or envelops 1 so that the said rectangular piece of metal toperates as a stopper to the flow of paste or other adhesive substance contained in the well I claim as my invention, and desire to secure by Letters Patent, the following:

1. In a pasting-machine, the combination of a base, arms pivoted thereto, a paste-well having its bottom in close proximity with the said sheets, saidarms being adapted to lift said paste-well in a substantially vertical direction when they are elevated.

2. In a pasting-machine, the combination of a base, arms pivoted thereto, a paste-well having its bottom in close proximity with the sheets to be pasted and provided with a longitudinal slot for the paste to flow through and a spreader carried by said arms and removed from said longitudinal slot so as not to prevent the free flow of paste directly to said sheets, said arms being adapted to lift said paste-well ina substantially vertical direetion and means for sustaining said arms when lifted.

3. In a pasting-machine, the combination of a paste-well having its bottom in close prox-- imity to the sheets to bepasted and having a longitudinal aperture through which the paste is free to flow forward upon said sheets, and a spreader resting upon the topmost sheet at a point considerably removed from said opening so as to permit the paste to flow forward upon said sheet but act to limit its forward flow, said paste-well being capable of an independent movement relatively to said spreader.

t. In a pasting-machine,'the combination of a frame having pivoted arms 0 0, a pastewell '5 i 6 adapted to be lifted thereby and normally in close proximity to the sheets to be pasted and having an aperture 17?. permitting the paste to flow forward upon said sheets, and a spreader f mounted in said arms at a distance from said aperture so as to permit the paste to flow forward on said sheets but act to limit said forward flow thereon, said paste-well being capable of an independent vertical movement relatively to said spreader.

5. In a pasting-machine, the combination of a base a, a frame having arms 0 c pivoted thereto, the paste-well 2' 2' adapted to be lifted thereby and normally in close proximity to the sheets to be pasted and having an aper- ROBERT F. PICK.
