CHARLES H. SNYDER, OF PERCIVAL, IOWA.

ROAD-SCRAPER.

Be. it known that 1, CHARLES H. SNYDER, a citizen of the United States, and a resident of Percival, in'the county of Fremont and- State of Iowa, have invented certain new and useful Improvements in Road-Scrapersjzof which the following is a specification.

This invention'is an improvement in road scrapers, especially desi ned for use as a four-horse road drag; am the invention consists in certain novel constructions and corn binations of parts, as will be hereinafter described and claimed.

.Fig. 2 is afsi e view thereof.

In the drawings Figure 1 is a top plan view of a sore. er. embodying my invention. Fig. 3 is a detail perspective view of one of the side sections. Fig 4 is a detail view illustratihg the draft chains 1n a different adjustment vfrom that shown in Figs. -1 and 2, and Fig. 5

is a detail perspective view illustratingthe tie chain for connecting the rear ends of the op osite sectionsof the scraper.

- 11 carrying out my invention 1 make the scraper with two side sections A, A, which are alike and are arranged side by side and being alike a description of one will answer for both. The side section A comprises the bladesA arranged in' series and one in rear of the other, and these blades are provided with stamlardsA and A securely fastened at their'lower ends to the blades and project mg upwardly therefrom, and the standards A are made longer than the standards A and pro ect higher than the said standards A and the several standard: A of each construction which permits the adjustment of the blades-to any suitable angle in the operation of the invention. The beams B and B are composed 'of bars of metal bent at their middles at B to form the opposite side bars, which extend back on opposite sides of their respective standards and the bent portions B at the front end of the beams orm seats in which are swiveled'the links 0 for'eonnection with the chains 1) leading to.

the evener bar E, as best shown in Fig.1 of the drawings. It will be noticed that I provide these chains D between the evener bar i E and each of the beams B and B. and by as wil be understood from Figs. 1 and 4, the

so 'takin up or letting out these short chains D,

opposite sections can be set in anydesired position.-

, In adjusting the blades to different inclinations, I provide one of the links A at its rear end with aclasp F, whiclmnay. be bent from the link and is open at its upper side to receive the upper rear end of t e slide bar G, which is pivoted at its lower end .G

to the beam B and is provided near its upper end with the bolt holes G which register with similar holes G in the links G to receive a,

pin H, the said construction operating when adjusted as shown, for instance in Figs. 2 and: 3, to form a )ositive connection betweeathe beam B and the link A, and thussecuring', the blades in any suitable adjustment to which they maybe set in the use of'the invention. This construction is simple, easily operated, and provides an efficient means for securing the blades of the scraper in any desired adjustment. A chain 1 connects the sections A at. their rear ends and preventssaid sections from spreading too farin'the operation of the invention.

Brackets'J on the o )POSitO sections are secured to the beamsB and project 11 wardly therefrom and are provided with aterally opening loops J in which the seat bar ear. rying the seat K is movable laterally so more or less of the riders weight maybe exerted] upon one or the other of the sections A, as

may be desired, pins K on the bar K limiting the lateral movement of saidbar as shown in the drawings. It will be noticed that each scctionhas its blades provided with integ nediatc standards A and with the side stand-' ards and for convenience in ad usting thebla'des to different angles, I referto provide the rear intermediate stanr ard with an extension A forming a handle or lever for use in adjusting the angle of the'different blades when the detent II is released.

In operation the drag may be set to draw the dirt from both sides of the road, and to fill up and smooth all ruts in both wagontracks, and when the sections are set with the blades straight across, the drag maybe op.- erated to pulverize and smooth the road.

It will be understood that each section may":

be set toany desired position by adjustingthe dr: chains D, as before suggested, and the bla es can be set to various angles by roperly manipulating the adjusting slides E}, as describe Iclaim"- I 1. The improved road scraper herein described,.comprising a air of sections each 1 side b side, each section having blades arran e one in'rear of the other and rovided wit upwardly rojectinginterme rate and side standards, earns connectin their respective 'standards and pivote thereto,

' links pivotedto and connecting the intermediate standards above the beams thereof and providedv with clasps opening upwardly, adjusting slides-npivoted at their lower ends to thebeams of the intermediate standards and inclining jthence upwardly andrearwardly, and restingin the clas s of their res ective links, said'adjusting sides and lin s having coincident openings, and a pin ing upwardly from the opposite SGClUlOHSfiIld operating in said openings, bracketsp'rojectprovided above the same with laterally openmg loops, a seat, a seat bar supporting the seat and held'in said laterally o ening loo s, an equalizer bar extending in a vanes of t e opposite sections, and chains connecting said bar with the beams of the opposite sections, substantially as set forth.

. 2. In a scraper substantially as described the combination of a series of blades 'arrangedone in rear of the other and provided each with an intermediate upwardly projecting standard and with upwardly projecting standards on opposite si es thereof, beams extending between and pivoted to their re spective standards, links pivoted'to and ex- 1 tending between the intermediate standards, and above the beam thereof, and an adjusting slide between the beam and links .of the-intermediate standard whereby to se a link connecting said intermediate standards above the'beam thereof, said link being provided with an upwardly opening claslp, an adjusting slide pivoted to the beam of t e intermediate standards and fitting in said clasp, and means for securingthe said slide in different, adjustments to the link, substantially as set forth.

' 4. A road scraper comprising-a series of blades arranged one in rear of t e other and provided with upwardly projecting standards and beamsfor said standards composed of bars bent between" their ends forming side bars lap ing on opposite sides of their standards an fitted thereto, and draft links in the bent forward ends of the said beams, substantially as set forth.

5. The combination ma road scraper of' l the op osite sections having blades and means fiir adjusting the same to different angles, brackets mounted on said sections and rovided with laterally opening loo 5, a seat Ear held in said loops, and a draft earn ex-.- tending across the front end of said sections, and connected therewith, substantially as set forth. i

6. In a road scraper substantially as 'described the combination of blades having upwardl projecting intermediate .and side standarc s and'having beams pivoted to and connecting their respective sections, one of the intermediate standards being provided with an u wardly projectin portion form ing a ban le in adprstingtie angle of. the blades, a link connecting the intermediate standards above the beam thereof, and adjusting means between said link and beam, substantially as set forth. i

7. The combination of a series of scrapers having upwardly pro'ecting standards and arranged one in rear 0 the other, a beam ivoted to and connecting said standards, a ink pivoted to and connecting the standards above the said beam, and an adjusting slide extending betweenthe beam and standard arid adjustably connected with one of said parts, substantially as'and for the purpose set forth.
