SPECIFICATION forming part of Letters Patent No. 508,032, dated November 7, i893.

Application filed December 6. 1892. Serial No- 454,268- (No model.) d

To all whom it may concern.-

Be it known that I, BENJAMIN F. MAsoN, a citizen of the United States residing at Wildwood, in the county of Sumter and State of Florida, have invented certain new and useful Improvements in Box-Making Machines;

- and I do hereby declare the following to be a full, clear, and exact description of the inven tion, such as will enable others skilled in the art to which it appertains to make and use the same. Y i

This invention relates to improvements in box making machines, particularly to that class known as fruit and vegetable packing or shipping boxes.

The object of the invention is to provide a suitable machine of. such novel construction, whereby all measuring, adjusting, &c., in the construction of this class of box, shall be entirely dispensed with.

A further object is to employ such novel 'means, whereby certain members of a box,

after being properly secured on the clamping frame, remain in such position Without further adjustment throughout the entire operation, or until the remaining members have been attached, to complete the box.

A further object is to provide a revolubly mounted clamping frame, and means for automatically or manually rotating the same when elevated, thus greatly facilitating the ready operation, and increasing the efficiency of the machine. v

-A further object is to present a simpleand inexpensive construction in a box making machine and'at the same time, one that shall be capable of rapid action, producing as a result, satisfactory and accurate work.

With these objects in'view, the invention consists in certain novel details of construction, combinations and arrangements of parts, to be hereinafter more fully described.

In describing the invention in detail, reference is had to the accompanying drawings forming part of this specification, wherein like letters indicate corresponding parts in the several views, in which Figure 1. is a view in perspective of one form of machine embodying "my. improvements. Fig.2.isaview in front elevation of the same, showing a boxin thejfirs'tstage of construction.- Fig. 3. is an-end view showing by dotted lines the operation of the revolubly mounted clamp frame. Fig. 4. illustrates detailed views of one of the clamps. Fig. 5, is a detail view in perspective illustrating a modi-' fied form of construction. Fig. 5 is a view in elevation of a portion of the same showing the ratchet and pawl mechanism. Fig. 5 is a detail face View of one of the standards, showing the guide. slots and the pinion engaging the rack, also by dotted lines, the normal position of the stud shaft when the frame is at rest. Fig. 6. is a detailed perspective view showing one form of completed box.

- In the drawings, A indicates a bench or table having at each end thereof the standards or uprights a a. and adjacent these uprights, the slots a a which latter are adapted for the reception of the clamp frame supports 1) b. Suitably mounted between the cross braces a a is a rock shaft a having a foot lever a secured thereto, the said lever connecting with the lower end of the left hand support b and the link a forming a similar connection with the right hand support, as is clearly shown in Fig. 1. Thus as the foot lever is depressed, these sup ports are forced upwardly through the slots in the bench top to elevate the clamp frame B. This frame may be constructed and proportioned to contain any desired number of clamps as will be readily understood, the distance between the same corresponding with any determined length of compartment of the box. Each clamp comprises a backing formed of the outwardly projecting arms b 19 and the vertical brace 19 The clamp proper G hinged at c is provided with an inclined or tapering surface which is adapted to be engaged by a pressure arm 0 mounted on a shaft 0 the said shaft being journaled in frame B (as shown) and controlled and actuated by a hand leverc Extending in opposite directions from each of the backers on the extreme ends of the frame B are short shafts D journaled to turn loosely in apertures 12' in the upper ends of the supports b and having their outer ends reduced to enter and project slightly beyond the slots to, a formed in the standards or uprights a a. Thus it will be readily obvious that any one of a number of clamp frames, with the number of backers and the distance between the same varying, may be readily adjusted or substituted for that shown on the machine.

Referring to Fig. 3.wherein the rotary movement of the clamp frame is illustrated, it will be observed that with a machine constructed as there shown, the force of gravity tends to effect the first quarter revolution of the frame as it is elevated, thus making the circularadjustment partially automatic; furthermore, when the frame is nicely balanced, that is to Referring to Figs. 5, 5 and 5" I have illustrated a slightly modified mechanism, by which the clamping frame when elevated, may be automatically rotated through an arc of ninetyd-egrees. This mechanism comprises the ratchet disks e -e which are keyed or "otherwise secured ont-hestud-shatts D-- of theclamping frame adjacent the outer faces of the framesupports --b-b-, and on these supports, spring press-ed pawls-e-care pivotally secured and adapted to engage saiddisk-s, thus limiting the frame to revolve in but one direction. The stud-shafts --D-- are reduced at their-outer extremities to form spindles --e -e on which are mounted anti-friction rollers -e-e-. These rollers are adapted to enter and move in endless guide slots -e: e formed in the facesof the standards a whichlatter are suitablyconnected atone end with the stud shafts and secured at the opposite eud to the table, adjacent the standards,

so as to act or exert a pull on the frame only when the latter is elevated. It "will be "obviens, that these springs may be shortened if desired, to hold the clamp frame well down against the table, at the same time being capable of drawing the rollers rearwardly and into the return slot as above described. To prevent the rollers entering the return slots when the frame is elevated, these slots adj acent the lower ends are curved inwardly or toward the advance slots e so as to cause the roller to normally rest at the lower end, of the last named slots, as is clearly shown in Fig. 5

To revolve the frame, it must be first ele- 1 vated so as to swing clear of the table, and to efiect this rotary movement automatically,

I key "on the stud-shafts adjacent the friction rollers, spur gears e -e which are adapt- 1 ed to engage segmental rack-bars -e-e These racks are secured to the vertical sup ports and in the path of travel of thegears, and as the frameis drawn into the return slot by the action of the springs, the gears engage the racks, and as the frame is carried downwardly by its own weight or the action of the springs, it will be given a partial revolution, the ratchet and pawl holding it against backward movement.

In Fig. 6 the ends f and the partitions f of the box F are placed in the clamps and the operating lever drawn downwardly to lock the same in position. One or more bottom boards or strips f are then nailed on, say when the spindles or-stud shafts are well A journaled, it requires but a slight pressure of the hand to rotatethe same,when elevated.

and the foot lever depressed, which elevates the frameand effects an engagement between the pinions and segmental rack bars whereby the frame is given a quarter revolution. At the same time the springs e" acting will tend to pull the rollers towardthe rear and thus jshift them to the return guides a when the foot lever is released and the frame descends by its own weight and automatically adjusts itself to the proper position, that is to sayfor the attachment of the side boards or strips f and after such pieces have beensecured a similar operation will present the opposite side of the box as will be obvious.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

1. In a box making machine, the combination with movable supports, of a clamping frame rotatably mounted thereon, and a stop arranged in the path of -'the clamping frame a."--. Thus, as the footlever is depressed, the frame will be carried upwardly by its supports -h-b-'with the, frictional rollers -e--etraveling in the l vertical portion -e of the advance slots arranged in the path of the clamping frame and arriving at or near the limit of its upward 1 i movement, the rollers will be drawn toward the rear 'or horizontally and into the return slot e by the action of the springs c to check its rotary movement, as specified.

2. In a box making machine, the combination with movable supports, of a clamping frame rotatably mounted thereonyand a stop to check its rotary and rectilinear movement, as specified.

3. In a box making machine, thecombinationwith a rotatablymounted clamping frame, of movablesupp orts whose direction of movement is perpendicular to the-axis of theclamping frame and means for operating said supports, as specified.

4. In a box making machine, a supporting table, a revolubly mounted clamping frame arranged vertically movable thereon and normally held against rotation by engagement with the table, andnreans for elevating said frame, as specified.

5. A clamping frame, comprising a series of backers or stationaryjaws, a corresponding series of movable jaws having the outer faces thereof inclined, and a rotatably mounted shaft carrying presser arms which are adapted to engage the inclined faces of said movable jaws to operate the latter,as specified.

6. In a box making machine, a supporting table, a clamping frame vertically movable in guides, a lever controlling said vertical movement, and means for automatically revolving said frame when the latter is elevated, as specified.

7. In a box making machine, a supporting table, a revolubly mounted clamping frame vertically movable in guides arranged on the table, a foot lever connecting. with. said frame,

to raise and lower the sameuand means for effecting a quarter revolution of the frame when elevated, as specified.

8. In a clamping frame, a supporting table, a revolubly mounted clamping frame held engage the inclined face ofsaid jaw and a lever controlling the action of said arm, as specified;

9. In a box making machine, a supporting table-having at each end a slotted upright and adjacent thereto suitable openings, of the clamp frame supports, projecting through the openings the rock shaft having a foot lever and link secured thereon, said foot lever and link connecting with the lower ends of said supports, and the revolubly mounted clamping frame carrying a series of clamps and being provided with stud shafts loosely journaled in said supports,said shafts entering slotsformedin the uprights, as specified.

10. In a box making machine, a table, a vertically movable clamping frame arranged thereon and revolubly mounted in suitable supports and means for automatically efiecting apartial revolution of the frame when the latter is elevated, said means comprising the ratchet disks --6 and spur pinions -e' mounted on stud shafts of the clamp frame, saidshafts being provided with terminal antifriction rollers, thepawls carried by the frame supports engaging the ratchet disks, suitable tracks or ways adapted to receive and guide the terminal rollers of the said shafts, the rack-bars into which the spur pinions work and the spring -e connecting with the frame whereby the latter is given a horizontal movement, as specified.

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