HENRY HUBER, OF CRESTLINE, OHIO.

PORTABLE LADDER FOR GATHERING FRUIT.

SPECIFICATION forming part of Letters Patent No. 310,43t, dated January 6, 1885.

Application filed October 23, 15554.

To (LZZ whom it may concern.-

Be'it known that I, HENRY HUBER, a citizen of the United States, residing at Crestline, in the county of Crawford and State of Ohio, have invented certain new and useful Imp rovements in Portable Ladders for G athering Fruit, of which the following is a specification, referenee being had therein to the accompanying drawings.

My invention relates to a portable adj ustable ladder for fruit picking and for other purposes; and the novelty consists in the construction, arrangement, and adaptation of parts, as will be more fully hereinafter set forth, and specifically pointed out in the claims.

The essential object of the invention is to provide a ladder which, in connection with a wheeled truck and a supporting-frame, may be adjusted to suit inequalities in the surface of the ground, side hills, &c. The degree of inclination may be readily adjusted to suit, and the wheels may be readily adjusted on the axles to allow the mounted ladder to be moved in the are of a circle or around a tree, as requirements may suggest.

Various means are provided for anchoring the device againstacci dental movement, among which are the carrying-wheels, one of which may be readily shifted to either side of the tongue, or upon the end of the same in a plane transverse to that of the tongue. A platform attachment is provided which, having one end rest upon the main ladder, is provided at the other end with a hook to engage with a limb of the tree, the hook being covered with rubber to prevent slipping. An adjustable platform is also provided, and is adapted to be readily engaged with the rungs of the main ladder. The parts pack snugly together for transportation.

The invention in its details is fully illus- 1' rated in the accompanying drawings, in which Figure 'l is a side elevation of the complete device with all its parts in position for service. Fig. 2 is an end elevation broken away to show the pivot of the vertical frame, and in dotted lines showing the means for maintaining the equilibrium of the ladder upon uneven ground. Fig. 2 is a top plan view show- (No model.)

I iug the wheels set to have the truck move in the are of a circle. In dotted lines I show a position in which the wheels anchor the truck against movement. Fig. 3 is an enlarged view of a detail in plan, and Fig. 4 a vertical section corresponding therewith. Fig. 5 is afront view, and Fig. 6 a vertical section, of the top' of the ladder with the basket or standing platform attached. Fig. 7 is a detail section; Fig. 8 a side view of the horizontal ladder attachment, and Fig. 9 a detail View of an anchoring-leg.

Referring to the drawings, in which similar letters of reference indicate like parts in all the figures, A designates the main axle in plates a and a, upon the upper and lower side of each end of which are furnished journalbearings for stub-axles B. These stub-axles are -shaped, the vertical arm 1) serving as a pivot for the wheel 0, and the horizontal arm I) as aspindle for the same. stubaxle is a toothed or perforated segment, B, which is engaged by a spring-catch, B, located upon the upper side of the axle A. By these means the angle of the wheel 0 may be readily adjusted to direct the truck in any desired direction or to anchor the same against movement, as seen in Fig. 2.

Pivoted to the axle A at (Z is a vertical frame, D, consisting, essentially, of an upper and lower horizontal bar, (1 and (Z respectively, and two uprights, d", the latter being perforated at (1* in the are of a circle having the pivot (Z for a center. Iins d", passed through the axle A and frame, allow the frame D to be adjusted to suit inequalities of the ground, as seen in Fig. 2.

To the bar (I is hinged at e the tongue E, and this tongue is provided with a wheel-spindle, e, upon its free end, and a spindle, e", upon either side near said end. These spindles are for the reception of a wheel, E, and this wheel may be changed from either side of the tongue to the end thereof, or vice versa, at

' will. In transportation this wheel is ordinarily arranged at the side of the tongue, and is arranged at the end when the machine is in use, as in being moved around a tree. A supplemental tongue, F, is provided with a series of vertical perforations, f, and it operates loosely 7 Rigid with the in straps f f secured upon the tongue E and projecting below the same, a pin, f, passing through the tongueE and into any one of the holes f to give a proper adjustment to the tongue F. A metal strap, f, is also secured to the rear end of the tongue-extension E, and this strap is adapted to receive avertical leg, G, which has a sharp end, 9, and is adapted to anchor the truck or support the same as necessity may require. The rear tongue or extension F is provided with a series of transverse horizontal holes, 71, and the tongue E is provided with similar series of holes, 2'. The holes 71 are adapted to receive a pin, h, which, passing through the perforated ears h and one of said holes h, serves to adjustably secure to the extension F a brace, II. This brace 11 has a series of holes, h, and, passing through straps h", secured upon the fellow brace H, is secured adj ustably thereto by a pin, h. The brace II is hinged'to the rear side of the bar d of the frame D. By a similar arrangement upon the front side of the bar (1 a brace, I, is hinged to the bar d, and has straps i, which receive a brace, I, a pin, passing through the brace I and into one of a series of holes, 5, in the'brace I. The lower end of the brace I has perforated ears '5, through which a pin, 17", serves to secure the said brace to the tongue E by engaging one of the holes 6. rangement it will be observed that I may readily and quickly adjust the frame I) with reference to the plane of the axle A by the pins (1 and that I may adjust it upon either the front or back side by means of the braces and pins last described.

The parts thus far described comprise the truck and its'vertical frame. By adjusting the wheels properly the truck may be easily forced in any desired direction, as around a tree, for instance, as indicated in Fig.

I will now describe the ladder and its relative features.

Hinged to the bar d of the frame I) is abar, J, and pivoted at j to this bar J is a block, K, having two lockingguides, 7.1, which receive plates L, secured upon the under side of the standards of the ladder M. This ladder is trussed longitudinally, as seen at m, and transversely, as seen at m, the ends of the truss-rods being fitted in sockets in plates on, secured to the sides of the ladder, and the lower ends of the standards have metal points m which are adapted to enter the soil. These points on? are used when the ladder is to remain stationary for any considerable time; but when the machine is to be frequently moved I provide that the ladder shall be carried bodily. For this purpose a pin, on. is passed through the ladder-standards and engaged in one of the holes v1 in the tongue E.

To hold a basket or other receptacle, or as a standing platform for the operator, I provide the device 1?, which may be secured to any of the rungs of the ladder, and may be adjusted to accommodate the incline of the ladder and By this arpreserve a horizontal plane to the bearing at will. This device is shown in detail in Figs. 5 and 6, and consists, essentially, ofaplatform, 1), having hooks 99, which engage one of the rungs of the ladder, and hooks p carried by adjustable braces 19, which hooks 1) engage the rung below. The braces 12" may be lengthened or shortened to suit the angle of the lad derby the pin 1)", or equivalentholding means.

R designates a ladder attachment having a hook, 1', covered with a rubber sheath, 1', and having round or flat plates of metalr secured to the under surfaces of the longitudinal bars, as shown in Fig. 9. The body of So this attachment may extend from one of the rungs of the main ladder, or from the platform 1? to a limb of the tree, and form a horizontal platform, upon which the operator may step to reach different portions of the tree which are inaccessible from the main ladder.

The rubber covering 1- is designed to prevent the hook from slipping or breaking the bark of the tree-limb or support over which the hook may be engaged. The attachment It packs snugly within the frame of the main ladder, as seen in Fig. 2, and the leg within the part B.

From the foregoing description the opera tion and ad vantages of the device will be readily understood.
