STOVE-TRUCK.

SPECIFICATION formingpart of Letters Patent No. 439,776, dated November 4, 1890.

Application filed March 28, 1890. Serial No. 34=5,'787. (No model.)

To all whom it may concern.-

Be it known that I, LEWIS GWINNER, of Hamilton, Butler county, Ohio, have invented a certain new and useful Stove-Truck, of which the following is a specification.

My invention relates to improvements in adjustable stove-trucks; and the objects of my improvements are to provide such con- 'struction as affords simple and reliable means of adjustment to diiferent sizes; of retaining arectangularform; of preventing the several parts detaching themselves while the truck is being adjusted; of being placed in the form of a trapezoid or of a triangle; of the several parts being detachable and interchangeable, which permits the truck to be knocked down for shipment and again set up for use without reference to certain parts for certain places, and, finally, of folding the truck closely together to occupya small space. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 represents the truck in perspective; Fig. 2, a plan of the truck; Fig. 3, an elevation of one of four similar parts which compose the truck; Fig. 4, a plan of Fig. 3, and Fig. 5 avertical section of a corner-plate.

Similar letters refer to similar parts throughout the several views.

A represents the corner-plate, on which one of the stove-feet rests B, a caster on which plate A is mounted.

O and D are similar parallel rods extensibly arranged in relation to each other, and which connect adjacent corner-plates A and form the sides of the truck. Rod 0 is rigidly attached to plate A by means of lug J and extends therefrom at a tangent in the plane of said plate.

Eisa guide rigidly attached to the extremity of rod 0 at a vertical angle and provided with a hole through which rod D slides; F, a guide similar to guide E, attached to an extremity of rod D, from which it depends, and is provided with a hole through which rod 0 slides; G, aset-screw inserted in guide Fand operating on rod 0; H, a pin formed on the projecting end of rod D, which depends vertically therefrom.

I and J represent lugs integral with plate A, locatedon opposite corners thereof. Lug

I is provided with a vertical hole, through which pin H of rodD is inserted. It extends outwardly, as shown at O, to receive stop K. Lug J is provided with a horizontal hole, through which one extremity of rod 0 is inserted and riveted. Its height equals the top of rod D.

Kisa stop removably inserted in extension 0 of lug I to limit the outward swing of rod D on pin H; L, a removable cotter inserted through the extremity of pin H, which projects through the hole in lug I to retain said pin in place.

M is a vertical flange raised on the outer edge of plateA integral therewith and connecting lugs I and J, which it strengthens. It is of even height with lug J and serves to prevent stove-feet placed on plate A from slipping off.

Nis a caster-stem depending from the center of plate A, either integral therewith or attached thereto by rivets or other ordinary means; 0, an extension of lug I outward to receive stop K, which is either removably inserted therein or cast integral thereto.

The truck consists of four similar-described parts, (illustrated by Fig. 3,) and is set up by inserting pin H of rodD of each part through the hole in lug I of each adjoining part throughout, said pins being retained by the insertion of cotters L. By the equal extension of opposite pairs of parallel rods 0 and D the truck may assume the form of a rectangle, when stops K, inserted in the extension 0 of lugs I, bear against rods D and retain said form. Difierent-sized rectangles may be secured by simultaneously extending or contracting opposite pairs of parallel rods 0 and D. Set-screws G, turn ed tightly against rods 0, retain any desired adjustment.

By removing any one of pins H from the lug I through which it is inserted each side of the truck maybe turned inwardly on pins H until the four sides are closely folded together.

By removing stops K from extension 0 of lugs I of any two adjacent corner-plates A of the rectangular truck said two corner-plates A may be adjusted near together, while the two corner-plates opposite thereto may be farther apart, thus causing the truck to take the form of a trapezoid, and is adapted to stoves Whose rear feet are nearer together than the front ones.

In setting up the truck three similar described parts only may be used, which will make a three-sided or triangular truck adapted to stoves having but three feet, and which is also convenient for carrying barrels Whose end is placed thereon, with flanges M resting against the barrel-head and against the chine.

The removal of stops K is necessitated only to form the truck to a trapezoid. For rectangular or triangular trucks said stops K may be integral with extension 0 of lugs I.

As flanges M are flush with the top of rods D, boxes and like'articles may be placed on the -,truck and conveniently moved'without'.

there being anyprojecting parts liableto inury.

W-henthe folding or knockdown features are notdesired, lugI may besimilar tolug J and rod I) inserted and fastened thereinwsimilar torod O in lug J throughout, which will produce a rigidadjustable-truck. This constructionisshown in Fig. 5.

For casters that havea non-rotating stem thesame maybe cast integral with plateA, as shown at N, Fig. 5; or said stem-may answer for asocket for rotating caster-stems by having a vertical hole provided therein.

GuidesE and F mayconsist of loopsfform ed on the extremities of rods OandD, respectively, through which the adjoining rod may slide.

I am aware thatadjustable stove-trucks mounted on casters have heretofore been made. .I do not therefore claim such a com- 1. In an adjustable stove-truck, the combiand mountedon a casterat one-end and supported at theother by a detachable hinged connection to other of said parts, substantially as described, and for vthe purpose set forth. Y

3. An adjustablestove-truck consisting of a series of similar parts, cach rovided with a vertical hole at oneend. and a vertical pin at the other, byv means of which said parts may be hinged together. 4. In a rectangular adjustable stove-truck,

thecombination, substantially as described,

with corner-plates A, provided with lugs I and J. and. flange M and mounted on casters B, rods Qattached to lugs J rods D, parallel to rods'O and extensibly attached'thereto by guides'E and F, and pinsI-I, dependingfrom the extremity of rods'D, inserted through lugs I, of stopsK, attached to lugs I to prevent rods D forming an obtuse angle with rod 0, extending from the. same corner-plate.
