To all whom it mayoncem.'

Be itknown that I, WILLIAM WESTMAN, a citizen of the United States, residing at Essex, in the county of Page and St-ate of Iowa, have invented certain new and useful Improvements in Trucks, of which the followingis a specification, reference being had p to the accompanying drawings.

This invention comprehends certain new and useful improvements in trucks, and relates particularly to a truck designed for use in moving stoves. 4 p v i The invention has for its primary object a .simple durable and efficient construction of devicenof this character by the use of which a stove maybeeasily elevated and detached from its base and easily rolled from one place to another, as desired, the invention consisting in certain constructions and arrangements of the parts that I shall hereinafter` describe and claim.

For a full understanding of the invention reference is to be hadto the following description and accompanying drawing in whichz-f l 1 f Figure luis plan view of a stove truck constructed .in 'accordance with my invens tion. Figf. isV aside elevation thereof. Fig. 3is an enlarged sectional view on the line 3 3 of. Fig.-1, and, Fig-4 is a trans# verse sectional view-'on theV line 4 4 of Fig. 2.

Corresponding and like parts are referred to in the following description and designated in the accompanying drawing by like reference characters-f v u My improved stove truck includes a preferably rectangular frame embodying side bars 1 and end'bars 2 joined together at the corners of the frame by rivets or similar fasteningde'vices', lplate braces 3 being located at the corners of the frame in order to insure therigid'ity thereof. The frame also includes Vdiagonal arms 4 which extend in-v wardly from the corner braces 3 and whichmay be integral parts thereof, they inner ends' of thearms being joined to a frame` riig l5.

The diagonally disposed arms 4; ofthe frame of my device support'in suitable bearings shafts 6 which extendmlongitudina'lly ofthe diagonal arms, as shown, and which are provided at their inner ends with bevel pini'ons 7, all of said pinions meshing with a miter gear wheel 8 the teeth of which face downwardly and which is secured to a central shaft 9' held by a Cotter pin orthe like,

as clearly illustrated in the drawings, The shafts G are provided at their outer ends with bevel pinions 10, said lastnamed pinions meshing respectively with horizontally disposed bevel pinions 1 1 which are interiorly threaded as indicated; at 12 for engagement with ,the exterior threads of screw jacks 13 which pass through the threaded openings of the pinions 11 and are suspended thereby. 'l

In order to operate the miter gear 8, a pinion 111 is disposed in meshing relation thereto, said pinion being secured to the inner'end of an actuating shaft 15 which is supported on a frame arm 4 and which is provided at its outer end with a squared tory to being rolled underneath the body .portion of a stove according to the height of the stove to be moved, whereby it will'not be necessary, under some circumstances, to

rotate the shaft 1'5 for any length of time in .y

order to yeffect. the engagement of the revoluble heads of the jack screws 13 with the bottom of the stove.

To render the truck.

itself capable, of being elevated within cere,` 4

tain limits, for this purpose, I mount theground or traveling wheels 17 in brackets 18 which are pivotally connected to the sides of the truck frame by apertured ear-s 19 and pivot -bolts 2O passing therethrough.

The brackets extend underneath the sides, of

the frames at the front and rear ends there;

one edge of each bracket constituting a shoulder designated 21 adapted to bear v against the underside of the truck frame to supportl the lat-ter inl its relatively low v sdckets being arranged in longitudinally ex- `handing series. In the present instance, there are three sockets in each set, but it is to be understood that the invention is not limited to this or any number of sockets. It 'willi thus beseen that the frame may be raised and the wheel brackets 18 swung inwardly toward each other and secured in diterent adjusted positions to vation'fof the truck frame.

y Preferably, each bracket, 18" is formed,

adjoining its pivot .ears 19 with inwardly turned lugs 27 which together constitute a shoulder adapted to abntagainst the under side of the truck frame when the brackets 18 have been swung inwardly to relatively vertical positions so las to hold the truck'rame atts highest elevation.. Y

From'the foregoing description in connection with the accompanying drawing the i v,operation of my improved' stove truck will be apparent. In-the practical use vof the device the frame is elevated as required so as to reduce the gack raising operation to av minimum and the truck 'is then rolled underneath the body of the stove, the, base unscrewedr from the body and the shaft 15 rotated so as to raise the 'jackscrews 13 and thev stove body, supported thereby. The base can then b'e taken away, for the: ltruck and thel rolled to any other desired point.

veo

'l Any suitable handles such as those indicated at 27 are secured to the frame of the truck whereby vthe latter may be easily,

rolled over the floor.

The jack screws 13 are each formed with longitudinal groovesl?)a designed to receive tongues or splines A32* formed onthe plates 3 or arms 4, whereby the jacks will bev raised when the pinion's 11 are turned.

' It is to be understood 'that while I have shown the braces 23 as arranged in pairs, the innermost braces maybe omitted, if desir-ed. To secure the ears 19 in. place, their pivot bolts 20 pass through blocks 2OEl that are' riveted or otherwise secured-to the angle iron side bars of the frame-work.

vll' le the accompanying drawing dis- `ntoi' my invention, it is to be underi that the invention 1s not limited there- .ut that various changes may be'made leaving a cleartrack stove body may be' what I believe to be the preferred veinin the construction, arrangement and proportions of'the parts without departing from the'scope of the invention, as delined in the appended claims.

What I claim is 1. A truck'of the character described, embodying a wheel supported frame-work, a miter gear wheel mounted in said framework and supported thereby, a plurality of bevel pinions meshing -withsaidgear wheel, shafts, to the inner ends of which said pinions are connected, 'the' shafts extending radiallyv and outwardly from the gear wheel, the frame-work embodying diagonal arms on which the shafts are journaled, bevel pinions secured to the the respective shafts, with the last named pinions, and formed with' threaded openings a d jack screws mounted in the corners of lthe 'frame-work and having threaded engagement with the openings of the last named pinions, and means for turning said miter gear wheel, whereby to simultaneously rotate the shafts and elevate the screws. f

2. A truck of the 'character described, including a framework embodyin side bars, wheel brackets'l provi ed lwith apertured ears embracing the sides of the frame-work and. pivotally connected thereto, wheels journaled in the respective vbrackets, the rear sides of the brackets being adapted to abut against ,the bottom of the frame-work to` hold the frame-work ina relatively low position, the brackets being formed in advance .of their pivots with in' wardly turned lugs constituting shoulders adapted toengage the under lside of they frame-work with the brackets Vmoved inwardly and the frame-work vsupported. in 4a, relatively high position, and braces pivotally connected to the trunnions of the wheels and provided at their upper and inner ends with clamping screws 'working in the slots of the frame-work side bars. 'v

3. A truck of the character described, including a wheel supported frame-work, embodying side and end bars, corner plates connected to said side. and end bars, diagonally extending arms formedintegral with the, corner yplates and extending inwardly therefrom, a frame ring `secured to the inner ends of said arms,l a miter gear wheel '80 o uter ends of bevel pinlons'meshlng slotted supported on said frame ring and formed with. downwardly facing teeth, pinions meshing with said gear wheel,

shafts jour- ,naled' o n the diagonal arms and carrying 'said pinions, -jack screws working in the corner plates, bevel pinions secured to the outer ends of said shafts, horizontallyv disposed bevelpinions, meshing with the last namedl pinions and formed with threaded .openingsextending therethrough, the jack screws working-through said openings and held from rotating therein, the frame also iso including another arm, a shaft mounted on my signature in the presence of two Withis' 'mmed arm and a gevel pinion4 carried messes. y sai last ynamed sha t uid meshnr with f 1 y T the mter gearA Wheel, whereby the trnng VILLIAM WESTMN 5 of .said shaft will rotatejall of. the other VVnesses:`
