JAMES T. HAMBAY, OF HARRISBURG, PENNSYLVANIA.

TUBULAR-FRAME WHEELBARROW.

To all 'whom'z't may concern:

Be it known that I, 'JAMEs T. HAMBAY, a citizen of the United States of America, and resident of the city ofHarrisburg, county of Dauphin, State of-Pennsylvania, have invented a new and useful Improvement in Tubular-Frame Vheelbarrows, of which the following is a specification.

My invention relates to tubular-frame wheelbarrows and the object of the invention is to improve the construction of the same so that they will be more satisfactory in use than heretofore. In the mounting of the tray on the frame it has been the practice to secure the same by rivets or bolts to cross-braces spanning between the two sides of the frame, the cross-braces being secured to the tubular-frame at each endby clamping the same thereto as hereinafter described. .As .it would weaken the frame too much at these points to make bolt holes therethrough, the securing of the braces to the frame has been ,dependent vupon frictional engagement. This has resulted in the serious defect of permitting the tray to slide forward on the frame against the wheel, caused by the striking of the frame or wheel of the barrow against obstructions. While this defect has been recognized for years and many'thousands of barrows are made each year, no efiectlve method for preventing-it has yet been put into practice.

The object of my invention is to remedy this defect by simple and effective means.

In the following I'have described, in connection witlnthe accompanying drawings, 'a

form of tubular-frame barrow showing my improvement in connection therewith.

In sa1d draw ngs, Flgure 1 1s a perspective view of a tubular-frame barrow pro-y vided with my improvement in one form;

Fig. 2 is a fragmentary side view on an en-' larged scale and partly. in section, showing another form of my improvement;.Fig. is afragmentary view, partly in section .and on an enlarged scale, of the form shown in Fig. 1; Fig. 4 is a cross-sectional view; of.

Similar letters of reference indicate SiIIli? lar parts throughout the several views.

7) indicates the reinforced edge 'of'thetray which adds to the strength of the tray and gives theedges a smooth finish.

I c indicatesthe tubular-frame, preferably formed of a singlelength of pipe bent to shape as shown.

(Z indicates the wheel, 6 the axle and f the axle bearing, securedto the frame by a bolt 9 which passes through the frame and also serves to, secure one end of front brace 7b, the other end of the brace being bolted or riveted to the tray.

2' and j indicate cross-braces spanning be tween the two sides of the tubular-frame and secured thereto by having their ends looped over the frame and bolted as shown in Fig.

.4, the bolts servingto hold the tray to the cross-braces, to secure the cross braces to the frame and to secure one end of strap is to the same. Strap 7c is shown as bent at Z to form a leg and then bent upwardly to form a brace m secured to cross-brace j in' a manner similar to that-shown in Fig. 4.

n indicates a leg-brace fastened at each of its lower ends to strap is at the leg bend i and at its upper bendtov the'cross-brace and ray. One form of my invention consists in lengthening the strap is so that it extends upper front portion of the from-cross-brace to aXle bearing f where it' is secured firmly to the tubular-frame by bolt g passing also through the axle bearing and the footof brace h, a hole through theframe at this point not'appreciably Weaken- The strap 70- thus abuts against any forward sliding movement. No part of the'tubular-frame is weakened by making additionalfholes therethrough, yet .the' whole structure isstiifened ands'trength- I ened.

In Fig. l the axle bearing fis shown as a single bearing secured to, the frame by but' one boltp- In Fig. 2 I have shown a double bearing secured to the frame by two bolts. Inthis latter, case the strap is k I may use a short length 0 andbolt the would be secured to the frame by the inner bolt as shown. Instead of lengthening strap j and the other for example to the inner belt of the axle-hearin This latter form could be readily utilized in connection with barrows already constructed so as to provide them with the improvement described What I claim anddesire to secure by'Letters Patent is -l. In a tubulai frame Wheelbarrow a cross-brace frictionally engaging the tuhular frame, an axle bearing and a rigid connection fastened at one point to the crossbrace and abutting against the axle hearing at its outer end, said outer end being secured to the tubular-frame adjaceni; the axle bearing.

Enema 7o 2. In a hubular-frame wheelbarrow cross-brace frictionally engaging the nub frame, an axle bearing and a rigid con tion fastened at one point to the crossand abutting against the axle bearing outer end, said outer end being secure the .tubulardrame by the same bolt an secures theaxle bearing thereto.

In testimony whereof I have signed specification in the presence of two suhse. ing witnesses" JAMES HA k'lrtnesses Gr. Ln Ann,
