PAD-MACHINE.

Specification of Letters Patent.

Patented Dec. f4, T9115.

Application filed September 14, 1910. Serial No. 582,066.

To all whom it may concern:

Be it known that I, ALBERT 1D. ALEXAN- DER, a citizen of the United States, residing at Fredericksburg, in the county of Spottsylvania and State of Virginia, have invented certain new' and useful Improvements in Pad-Machines, of which the following is a specification.

My invention relates to pad machines, and more particularly for making that class of pads used in packing furniture, and the like, in which excelsior or analogous material is used. y W

The object of the invention is to so construct the same that it may be connected with an excelsior machine, the material from the excelsior machine be received by the device and by the mechanism thereof may be properly directed and distributed upon the paper, the glue automatically applied, and the pad delivered from the machine and cut into proper lengths. I

A further object of the device is to make a simple, cheap, and easily constructed device that will have as few parts as possible, that can be easily assembled and repaired when necessary, and one in which single or double pads may be manufactured, as desired.

In the drawings forming a part of this specification, and in which like symbols of reference represent corresponding parts in the several views :Figure 1 is a sectional side elevation of the machine; Fig. 2 a similar view to Fig. 1, showing the picker cylinder and filling chamber; Fig. 3 a front view of the knife and its operating mechanism; Fig. 4 a front view of the filling chamber showing the regulating sides; Fig. 5 a plan view of the folder; and Fig. 6 a view of the glue pot.

1 is a power belt leading from the pulley 2, driven by any suitable power; 3 the picker-shaft to receive motion from the same; 4 the picker-head; 5 the casing surrounding the picker-head; and 6 the spring to hold the hinged support 58in place.

7 is a band communicatingmotion to the pulley 8; 9 a sprocket-chain connecting picker-shaft 3 with speed change pulley 10, said pulleys 10 and 11 being adjustable speed pulleys operating by friction, to regulate the speed of the device and 12 a chain belting for delivering the excelsior from the excelsior machine.

13- is a press belt to hold the excelsior on the feed belt; 14 and 15 are supporting timbers of the device; 16 base timbers connected to the same; and 17 upper platform of the same.

The feed belt 12 and presser belt 13 are preferably located between two brace timbers, not shown connected to the vertical support 14.

18 is a presser roller to hold the excelsior as it passes to the picker cylinder.

19 is the filling chamber in which the excelsior is received and delivered to the paper, said chamber having wings 20 and 21, shown in Fig. 4, for the purpose of regu-. lating and properly distributing the excel- S101. This chamber may be used in any machine.

22 are the hinges supporting said wings and permitting regulation of the same; 23 a bar contacting with the wings and 24 thumb nuts for adjusting the bars and holding the wings in their adjusted position.

25 and 26 are bars and 27 and 28 thumb nuts for bracing and holding the frame of the filling chamber.

29 and 30 are the glue pots regulated by

valves

31 and 32.

The glue feeds into a perforated cylinder 33, shown in Fig. 6. The

paper

34 and 35 is fed over the cylinder 33 and receives at its edges theglue as it is delivered from the glue pots. When a single pad is to be made only one paper strip is used; but when a double pad is desired, the two strips are brought into requisition. The excelsior is fed between the

rolls

36 and 37 and passes down between

rolls

38 and 39, the paper being on both sides of the same.

Rollers

37 and 39 are journaled in a hinged support 58, which is connected to the main frame by hinge 59; said support being held in place by a spring 6, heretofore referred to.

40 is a presser roller to hold the paper down, and 41 a folder in proximity to the same, said folder being pivoted at 42 to the frame, so that its forward part, which has overhanging or depending edges dips down and contacts with the edges of the paper and curls the border of the same. The float is, preferably, three-fourths of an inch thick, and its inclined or overhanging edge is, of course, more inclined at one side to give the initial turn to the paper and thus permit one side to be received within the other, to make a fold. In a single pad the edges are folded upon each other, and in a double pad suficient of the edges turned to permit the supplemental strip being connected to the same. Of course this presser roller 40 will be of a width in accordance with the size of the pad desired.

43 and 44 are rolls operated by sprocket chains 45 and 46, which are operated from the driving mechanism, for delivering the paper pads upon the belt carrier 47.

48 is a knife which automatically severs the pads at a predetermined time as they are delivered from the machine. This knife is normally held raised by a spring 19, but as the sprocket chain 50 is operated through the medium of sprocket chain 51 the lug 52 comes in contact with cross-bar 53 of frame 54, which carries the knife, and lifts the knife-frame against the power of spring 49, so that when the lug releases the frame the spring causes the knife to descend upon the pad and sever the same.

55 are links connecting spring 49 with cross-bar 53.

56 is a sprocket wheel fOr operating sprocket chain 51, the same receiving power from sprocket wheel 57 on change pulley 11.

The operation of the machine will be apparent from the foregoing description. The

excelsior is received, as it is delivered from the excelsior machine, upon the feed chain belting 12 and passes up onto the picker head whence it is delivered into the filling chamber and properly distributed through the medium of the rolls upon the paper; in the meantime the glue is being automatically applied and the pad is severed by the knife and delivered upon the carrier belt.

Having now described my invention, what I claim as new and desire to secure by Letters-Patent, is

1. he pad machine, the combination'with means for delivering filling material to the same, of paper strip supplying means, valvecontrolled glue pots having perforated cylinders connected to the same to guide the strip and spread the glue thereon, and means for directing the filling material on the pasted strip.

2. In a pad machine, the combination with means for delivering the material to the same, of a picker head to receive and distribute the' material, a filling chamber to receive the material, rolls to deliver the paper and the material on the same, including fixed rolls and movable rolls cooperating therewith, a hinged support carrying the cooperating rolls, and a spring at the upper portion of said hinged support to normally hold the movable rolls in contact with their companion rolls.

8. In a pad machine, the combination with means for delivering the filling material to the same, of a picker head to receive'the material, a filling chamber to receive and regulate its supply, means for feeding the paper strip forward, glue pots having perforated cylinders connected therewith for spreading the paste upon said strip, rolls to deliver the filling material to the pasted strip, means for normally holding the rolls in contact, and an oscillating folder provided with overhanging edges adapted to curl the paper and form the pad.

4. A pad machine, comprising means for conveying the material to the same, means to regulate its supply, rolls to feed the paper and material, means for supplying the glue, a presser'roll for the paper, a converging folder toform the pad, a chain carrying a lug, aknife adapted to be operated by the lug, a frame journaled in the machine and carrying a knife, a spring to hold the frame normally suspended, and connecting means between the various rolls, so that they may all be operated from the common source of power.

In testimony whereof I afiix my signature in presence of two witnesses.

ALBERT D. ALEXANDER.
