VENEER COlLlNG AND NAILINQ MACHINE.

SPECIFICATION forming part of Letters Patent No. 628,085, dated J uly 4, 1899.

Application filed July 30, 1898. Serial No. 687,249. (No model.)

T at whom it may concern.-

Be it known that I, GEORGE A. GAGE, acitizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Veneer Coiling andNailing Machines, of which the following is a specification.

My invention relates to veneer-packageforming machines, and has particular reference to coiling and nailing the veneering to form cylindrical packages.

The main object of my invention is to provide a machine which will facilitate the abovementioned operation' To this end I provide a nailer operating in conjunction with an improved collapsible coiling-drum.

The objects of the particular features of construction hereinafter claimed will be understood from the following description, with reference to the accompanying drawings, in which- Figure 1 is a front elevation of a machine constructed according'to myinvention. Fig. 2 is a side view of the friction-

pulleys

12 and 18, showing the position of the depression 12 when the pulleys are out of frictional contact. Fig. 3 is a top plan of the machine, showing mainly the mechanism for operating the nail'er and omitting other details of the machine. Fig. 4 is an end elevation Fig. 5 is a vertical section through the lever at and shafts within same on the line a: sect Fig. 1. Fig. 6 is a horizontalsection through the lever 4 and shafts on the line y y of Fig. 5. Fig. 7 is a Vertical section through the sleeve 7 and shafts within same on the line z z of Fig. 1. Fig. 8 is a vertical section of the casing 31, showing the inclosed mechanism of the nailer. Fig. 9 is a side View of the cam 34 of the nailer.

, Fig. 10 is a perspectiveview of a metal nailing-strip adapted for use with my nailer.

The machine consists, mainly, of aoollapsible drum mounted on the shaft 2 and having an umbrella action operated by the lever 4 andanailer travelinglengthwise of the drum. The shaft 2 is hollow, slotted at 2 and 2, and journaledin the

members

13, 15, and 16 of the frame. .The shaft 1 is longitudinally movable in the shaft 2 and has a pin 1 projecting through the slot 2 into an annular groove 3 in the sleeve 3. The sleeve 3 is loose on the shaft 2 and is pivoted to the le ver 4 at 4. The lever 41 is provided with a handle at its free end and is pivoted to the frame at 5. The sleeves 6 of the drum are rigid on the shaft 2, and the sleeves 7 are longitudinally movable thereon and are con nected to the shaft 1 by a pin 1, passing through the slot 2". Arms 8 are pivoted at theirinner ends to lugs 9 on the sleeves 6 and 7 and at their outer ends, at 10, to the segments 11 of the drum.

The shaft 2 is driven by the friction-pulley 12, which is rigid thereon. The pulley 12 is driven by frictional contact with the pulley 18, which is rigidly mounted on the shaft 19 of the driving-pulley 22, journaled in the member 13 of the frame. The pulley 12 is at rest when the depression 12 is presented to the pulley 18, as shown in Fig. 2. To start the pulley 12, the operator depresses the step 20 of the lever 20, and the tooth 20, engaging with one of the teeth 12 on the pulley 12, will turn same sufficiently to bring it into frictional contact with the pulley 18, and thus cause same to make a single revolution. The lever 20 is slightly flexible at the part between the fulcrum 21 and the spring 21. The lever 20 is fulcrumed on the frame 21 and is normally held in the position shown by the spring 21'.

When the lever 4. is pulled toward the drum, the same, operating on the sleeves 7 through the shaft 1, will collapse the drum. Before the drumis collapsed at the end of each revolution the nailer is brought into operation, the operator depressing the step 26 of the lever 26. The lever 26 is fulcrumed at 25 on the member 25 of the frame, and its arm 26, acting against the sheave 23,throws its clutch 23 into engagement with the pulley 22 and turns the sheave so as to wind up enough of the cable 27 to carry the 'nailer the required distance along the drum. This is done by a single revolution of the sheave 23, which is then thrown out of engagement with the pulley 22 by suitable mechanism, such as a cam '23 on the sheave 23, having contact with an arm 14 on the member 14 of the frame. The fulcrum 25 is in a slightly-higher horizontal plane than the free end of the arm 26, thus permitting the movement of the sheave 23 by the action of the cam 23. The cable '27 is secured at one end of the sheave 23, passes over the sheaves 28 and 29, and has a weight 30 for bringing same back into the position shown in Figs. 1 and 3 when the pulley 23 is out of engagement with the pulley 22. The sheave 28 is journaled in the position shown on a suitable support, which is not shown in the drawings.

The casing 31 of the nailer is rigidly secured to the box 35' by the arms 31 and has a plunger 32 vertically movable therein and pressed normally downward by the spring 33, one end of which is seated in the casing and the other end in the plunger. Ashoulder 34 on the plunger has contact with the cam 34 for raising the plunger. The striking member 32 is secured in the end of the plunger by the set-screw 32". The cam 34 is rigid on the shaft 35. The shaft 35 is also journaled in the

boxes

35 and 35, which are slidingly mounted on the rods 46. The rods 46 are secured to the

members

46 and 47 of the frame. A sleeve 27 is loose in the shaft 35 and is secured to the cable 27. The pulley 37 is rigid on the shaft 35. The clutch 37 is feathered to the shaft and normally urged into engagement with the pulley 37 by the spring 35. The member 37" is rigid on the member 46'of the frame and throws the clutch 37 out of the engagement with the pulley 37 when the naileris in the position shown. The pulley 37 is driven by the belt 38 over the driving-pulley 40, which is journaled in a suitable support. (Not shown in the drawings.) The idler 39 is journaled in bearings 34, sliding on the members 44 of the frame in similar manner as the boxes 35' and 35 slide on the rods 46, the members 44 being supported by the

members

45 and 46 of the frame. A sleeve 43 is loose on the shaft of the idler 39 and is secured to the cable 43, which passes OVGI the sheave 41 and has a weight 42 at its free end. The idler 39, acted upon by the weight 42, preserves the proper tension on the belt 38. Aguide 36 is secured to the casing 31 and serves to hold a pronged metal nailing-strip in proper position to be operated upon by the nailerin securing same to the veneer package. A presser-roll 48 is pivoted to the rod 49, which is slidingly supported in the member 47 of the frame. \Veights 50 are seen red to the rod 49 and keep the roller in contact with the veneering while same is being coiled upon the drum.

In operating the machine a sheet of veneering is fed from the front upon the drum with its forward edge in the groove 11 in one of the segments 11 when in the position shown in Fig. 4. The operator then starts the pulley 12 by means of the lever 20, and the drum is thereby caused to make a single revolution, coiling the veneering so that its ends overlap. The outer lap of the coil is then under the nailer, the drum having stopped at the end of its revolution through the position of the recess l2in the pulley 12. The operator now throws the sheave 23 into engagement with the driving-pulley 22 by means of the lever 26, and thereby starts the nailer on its course across the drum, a nailing-strip 51 having been previously inserted in the guide 36 with its front end projecting under the nailer. As soon as the clutch 37 is free from the member 37 the clutch engages the pulley 37 and starts the operation of the nailer. The spring 35 now forces the clutch 37 into engagement with the pulley 37, thereby causing the shaft 35 to revolve, causing the cam 34 by action against the shoulder 34 to raise the plunger at each revolution, the spring 33 driving same down upon the nailing-strip, and thus driving the prongs 51 into the material of the package. When the nailer has traveled to its limit toward the member 47 of the frame, the sheave 23 is disengaged from the pulley 22, as before described, and the action of the weight 30 then draws the nailer back to its former position until .its clutch 37 again comes in contact with the member 37, whereby the pulley 37 is caused to run loose on its shaft and stop the operation of the nailer. The drum is now collapsed by means of the lever 4, and the member 16 by means of the handle 16 is tilted away from the shaft 2 on its pivotal connection at 16", so as to permit the removal of the veneer package.

It is plain that the details of construction of my device may be altered in numerous ways Without departing from the spirit of my invention. I do not therefore confine myself to such details.
