COMBINED COVER PRESS AND I NAILING I AGHINE.

Application Med December 16, 1924. Serial No. 758,238.

To all whom it may concern: 7

Be it known that I, GEORGE D. PARKER, a citizen of the United States, residing at Riverside, in the county of-Riverside and State of California, have invented certain new and useful Improvements in Combined Cover Presses and Nailing Machines, of which the following is a specification.

This invention relates particularly to a machine for nailing the lids and cleats on filled orange or apple boxes, but is as well adapted to nailing covers on boxes of any kind whether containing fruit or other commodities, or for nailing the bottoms on empty boxes.

In packing oranges and apples it is customary to overfill the boxes so that the fruit extends considerably above theisides of the boxes. In nailing on the lids a bulge is created at the center of the top since the fruit when packed cannot be completely pressed into the boxes. This overfilling when packin is necessary to take care of natural shrin age of the fruit during shipment and storage so the consumer will get a full box.

The fruit is most carefully packed into each box by hand, each fruit usually being wrapped in paper and symmetrically placed in the box.

In nailing the lids or covers to the boxes, the practice heretofore has been to provide a foot press along the runway down which the boxes are passed, adapted for manual operation to spring and clam the cover in place and securely hold it w ile the operator places the end cleats over the corners of the covers and nails them in place, after which the clamping mechanism is released and the closed box passed and another placed in its position and operated on in the same manner.

This manner of securing the covers to orange and apple boxes is more or less of a laborious procedure and the nailing is not always secure, the placing of the nails and the numbers of nails used on each cover being more or less optional with the operator considerable variation in the quality of the work occurs during a days run and .many boxes are passed that are not as securely or as well nailed as they might be.

In the invention disclosed herein I proclamping and springing of the cover in correct and proper position on the box is a manual operation by manipulation of suitable mechanism for the purpose through the.

medium of a. foot lever.

It is a prlncipal object of the invention, therefore, to provide a machine wherein the important. operations of positioning and nailing the covers and cleats on the boxes is performed by suitable accurately operative automatic mechanism.

It is a further object of the invention to provide a machine for the purpose that will have the manipulatiomof the placin and clamping mechanism under the manna control of an operator so that propel-precautions may be taken durin this operation to prevent any damage or displacement of the fruit as it is being pressed down into the box by the cover as it is sprung and clamped into place for nailing.

It is also an object of the invention to provide a self contained unitary machine, simple in construction; easy and durable in operation and having automatically oper ative mechanism where such can be advantageously used and having manually manipulative mechanism where such seems better suited to the purpose, both of which mechanisms are coactive and cooperative to produce the result desired in the minimum of time and without the need of a skilled operator.

lVith such objects in view as well as'other advantages inherent in the invention, I wish it understood that the novel structural peculiarities; novel organization of elements and the separate and collective operations involved in carrying out the objects of my invention may be varied in their proportions, placements, general arrangement and operative relation without departing from the scope and nature of the invention.

In carrying out the objects of the invention-in a concrete form or machine other employ, and some of the parts and com binations of parts may be used without the others in different types of such machines without departure from the purview of my invention, and I regard myself as entitled to such variations from the shown and described devices as fall within the scope and meaning of the claims hereto appended.

Reference now being had to the accompanying drawings in connection with the description to follow will give a much clearer and more comprehensive understanding of the arrangement and operation of a machine emborying my invention.

Figure 1 is a front elevation of a machine embodying my invention. The position of the various parts in this view is just at the end of an operation. The box lid and cleats have been nailed in place on the box and it is ready to pass on and the next box takes its place. The movement of the boxes past the machine is in the direction of the arrows on the box sides. The nail hoppers and parts carried on the top of the machine have been omitted in this view. The nailing apparatus is substantially like that used on all of my various box nailing machines and has been repeatedly shown and described in previous patents so that it is deemed unnecessary to show it in detail in this application and drawings. The various operative arts that are new with this machine are 0 early shown. This view ver clearly shows how the bulge is produce in the top of the box when the cover is permanently applied, to take care of the natural shrinkage occurring during shipment and storage of the fruit. As the shrinkage takes place the cover will tend to flatten and hold the fruit in place so that at no time will it be loose enough in the box to lose its symmetrical arrangement of packing. When the fruits are hand packed in the boxes each individual fruit is wrapped in paper. In this view as well as subsequent views I have shown the fruit as packed without the paper wrapping to better show its arrangement in the box.

Figure 2 is a side elevation of Figure 1 looking from the right. The positions of the operative elements in this view, however, are more nearly like that of Figure 4. A box is in nailing position with the cleats and cover clamped in placed ready for the nailing operation. In this view I have shown the positions of the nail hoppers and the mechanism for operating them, merel as indicating how the appear on the mac ine.

Figure 3 is an enlarged view of the clamping mechanism in relation to a box cover in position to have the cover sprung down over the fruit and clamped in position ready for nailing. Most of the frame work has been omitted as well as all of the nailing mechanismw'The clamping mechanism is in transit, being under movement through the depression of'the foot pedal provided for the purpose. The flashers for engaging the ends of the cover and alignin it with the box have just reached the limit of their pivotal movement and are just about to advance .vertically, first carrying and positioning the cleats onthe outer ends of the cover and then springing the cover down onto the box and at the same time pressing the fruit down into the box with the bulge in the center being formed during this pressing operation.

Figure 4 is a similar view to Figure 3 but with the cover and cleats clamped in place ready for nailing and the bulge in the top fully developed. The foot lever is now ratcheted in place and another foot lever manipulated which sets the nailing mechanism in operation. This latter lever and the nailing mechanism are omitted from both Figs. 3 and 4 to give clarity to the drawings.

Before proceeding with a more detailed description of the construction and operation of the illustrated machine embodying my invention I wish to mention that the several views constituting the drawings herewith were selected and portrayed in a manner that was thought would best illustrate the inventive thought without confining the showing to an exact scale or dimensions. The operative features may be more or less diagrammatic; some parts may be more or less out of relative proportion and the engineering features of construction may be somewhat at variance with the best or preferred practices in machines of this type. With this understanding of the accompanying drawings we may proceed with the more detailed description of the construction and operation of the machine as illustrated.

The general arrangement of the machine contemplates a base member 1 on which are mounted frame supporting and bearing members 2 and 3, the members 2 and 3 carrying upright members 4 and 5 which latter members constitute the main support for the operative mechanism above the base structure.

A motor 6 provides suitable power for emma drivin the moving parts of the machine throng the medium of a silent chain drive indicated at 7, passin from the motor shaft to a clutch gear 8. he clutch gear 8 being manipulated through the movement of the clutching mechanism 9 operated by movement of the foot lever 10 and connecting parts. 11 indicates a brake drumand mechanism for stop ing the machine instantly whenever the c utch mechanism is released. The clutching and brake mechanism is standard construction as used universally in my various types of nailing machines as shown and described in my previous patents and needs no further description in connection with this machine as it forms no part of this invention except in its combination with other elements.

The clutch gear 8 is mounted on a shaft 12 the outer end of which carries a pinion 13 meshing with the large gear 14 mounted on the shaft 15. The large gear 14 forms a crank gear together with the crank arm 16 on the opposite end of the shaft 15, where- 1 by through the medium of the connecting rods 17 and 18 the nailing mechanism is brought into operation, whenever the foot pedal 10 is depressed.

On the left end of the shaft 12 is placed a hand wheel 20 for manual manipulation of the machine in emergency.

Integral with the clutch gear 8 is a pinion 21 meshing with the reduction gear 22, the hub of the gear 22 carries a pinion 23 meshing with the gear 24, the hub of the gear 24 carries a pinion 25 meshing with the gear 26.

On the shaft 27 carrying the gear 26 is mounted a crank 28 which crank operates the nail pan and attendant mechanism through the connecting rod 29. Figure 2 is the only view that shows these various gear connections as they all relate to the opera-. tion of the nail pan and are only introduced to give a comparatively slow movement to. the nail pan and mechanism in relation to the other movements in the machine and are not shown in further detail as they are practieally the same in operation, construction and general arrangement as is used in my other various box nailing machines and are fully described and illustrated in my previous patents.

We will now leave this part of the apparatus and proceed with a detailed description of the mechanism that forms the subject matter of this invention, understanding of course that the parts just described form a part of the invention in combination with the other operative mechanism.

Suitably positioned on the upright frame members 4 and 5 are table members 30 and 31 carrying on\ their upper faces the roller conveyor member 32 over which the boxes are passed in sequence as they are operated on by the nailing machine. This conveyor 32 forms a link of a continuous conveying stem over which the boxes are moved in t eir passage through the packing house and is placed in such alignment therewith that the boxes move onto and off thereof without any particuar attention from the operator of the machine.

The upper ends of the frame members 4 and 5 are tied by bein secured to the cross member 33, they thus orm rigid guides and sup orts for the cover clamping and nailing mec anism.

Mounted adjacent the top of these frame members 4 and 5 is the nailing frame 34. actuated by the connecting rods 17 and 18 which are also standard construction on my nailing machines, their action coming into effect during the nailing operation wherein the nailing members or chucks are brought into pressing contact with the parts to be nailed, the springs 36 compressing to' take care of oversize shocks thereby driving flush nails at all times. 4

Mounted on the frame members 4 and 5 directly under the nailing frame is the pressing mechanism for placing and holdmg the cleats and covers in place until engaged by the nailing mechanism.

This pressing mechanism comprises the clamping frame 37 carrying the bearing arms 38 on the outer. ends of which the flushers 39 are pivotally connected. Intermediate of the frame 37 are crank shafts 40 carrying on one end the cranks 41, the connectin rods 42 connecting the flushers 39 with the cranks 41. On the other ends of the crank shafts 40 are mounted the crank arms 42, having operative connection with the rock shaft 43 carried by the table members 30 and 31, through the medium of connecting rods 44. .A crank 45 mounted on the shaft 43 serves to actuate the rods 44 and the attendant connections just described. Also mounted on the shafts 40 are step members or arms 46 having adjustabie stop members in their outer ends for engaging the top of the frame member 37 and thus regulate the positions of the flushers when they are moved into clamping position, this action being clearly shown in Figure 4.

The operation of the pressing and clamping mechanism is entirely manual and is brought into action through the operation of the foot lever 47 finding pivotal connection at 48 in the bearing member 2. The foot lever 47 is shown in its highest position in Figure 1 and in its lowest position in Figure 2 in which cases the presser frame 37 is in its highest and lowest positions. Fig. 1 showing the highest, Fig. 3 an intermediate, and Fig. 4 the lowest positions. Fig. 2 also shows the lowest positions of the parts but they are not so clearly shown as in the other gures.

The foot lever has operative connection with the presser mechanism through the medium of the connecting rod 49 and crank arm on the shaft 43.

Pivotally mounted on the table member 30 is a swinging ratchet lever 51 held in a normal operative position by a spring abutting against the bearing member 2. Carried on the foot lever 47 is an' auxiliary foot operated ratchet lever 53, Fig. 2. When the foot lever 47 is fully depressed as in Fig. 2 the ratchet lever 53 is in operative engagement with the ratchet arm 51 thereby holding the foot lever securely in its downmost position b means of pawl 53 and spring, and also olding the box cover pressing mechanism securely down on the cover while the nailing operation takes lace.

The crank gear 14 carries on its rim a cam portion 54, Fig. 2, the purpose of which will be explained in referring to the operation of the machine. The ratchet arm 51 carries a cam roller 55 which coacts with the cam 54 to cause a release of the ratcheted arm 51.

I will now proceed with a description of the operation of the machine when nailing the covers on orange or apple boxes.

This description may vary somewhat for different conditions in different packing houses or for nailing the covers or bottoms on boxes for other purposes but will be substantially as here given for the fruits mentioned.

\Ve will sup ose that the machine is in the position 0 Fig. 1, the completed box in this view having been passed along the roller runway the next approaching box seen at the right is placed in position under the presser mechanism. The operator places the cleats 56 in the flushers 39 which are held in place with the spring pressed latches 57, he straightens the cover squarely on top of the oranges or apples and in'alignment. approximately, with the ends of the box, the side alignment being accomplished through placing the cover against the guide bar 58, best shown in Fig. 2, the guide bar 58 also serving to align the box laterally when it is placed in position. Below the guide bar 58 is a companion guide bar 59 carrying a box stop member 60 adjusted to position the box longitudinally as it is placed in position on the machine. Having placed the box, cleats and cover in approximate positions the operator places his foot on the operating lever 47 and begins depressing it. This depression actuates through the various connections described, the flushers 39, cranks 41, 42 and 46, moving them into the positions of Fig. 3. It is here seen that the stop cranks 46 are against the top faces of the presser frame 37 which brings the operating faces of the flushers 39 into engage ment with the ends of the cover and corrects any slight misalignment that may exist and places the cover in the desired alignment with the ends of the box.

Continued pressure on the foot lever 47 will now begin to move the presser frame 37 downward, all of the other mechanism hav ing been stopped when the arms 46 contacted with the top of the frame 37, the whole mechanism now moving as a single unit into the position of Fig. 4, carrying the cleats and cover down onto the box and compressing the fruit down into approximately the positions shown, leaving a bulge in the center of the cover. In order to prevent the bulge from remaining too high and thus shortening the cover so it will not be securely nailed at the ends a center pres'ser bar is provided as indicated at 61. .Vhen the mechanism has reached the position of Fig. 4 the foot lever will have reached the position of Fig. 2 and the auxiliary foot lever will have engaged the ratcheted arm 51 and thus locked the foot lever in place.

The cover and cleats are now securely held in place ready for nailing to the box. The operator now places his foot on the lever 10, actuating the clutch member 9 to engage the clutch with the operative mechanism through the clutch gear 8 and attendant parts as have been described. This act places in operation the nailing mechanism which descends and nails the cleats and cover to the box in substantially the same manner as takes place in any other of my nailing machines.

As soon as the operator has locked-the lever for clamping the covers in place and placed his foot on the lever for actuating the nailing mechanism he can if he desires di rect his attention to the next approaching box and cover as the remaining operations of nailing and releasing the clamping mechanism are entirely automatic.

As soon as the nailing mechanism is brought into action the crank gear 14 and crank 16 begin to rotate and lower the nailing mechanism down into contact with the cover and continued movement of these parts will drive the nails and return the mechanism to its up position, at which point the lever 10 automatically releases when the brake mechanism will come into play and stop the parts immediately.

When the crank gear 14 begins to rotate the cam 54 Fig. 2 rotates with it and as soon as the cam engages. the roller 55 on the ratchet arm 51, the arm 51 is drawn away from contact with the foot lever 53 which permits the foot lever 47 and all of the cover clamping mechanism to move up into their inoperative positions through the action of the spring 62 Fig. 1, the upper end of which is secured to the nailing frame 34 and the lower end to the connection carrying the lower ends of the rods 44. An additional spring 63 is also provided to assist in bringing the various parts back to their inoperative positions.

There are times when the cleats are nailed to the covers before'they are passed to the cover nailing machines. In these cases the spring pressed latches 57 are swung up out of the way and held by the same springs as hold them in operative position;
