Application filed May 25, 15 25.

This invention relates in gent-rat to snow plows of the type in which there is employed a rotary impeller for delivering the snow from the machine but more specifically the invention relates to ii'uproved means adapted for use in connection with the discharge chute oi the hope ler casii'ip the chute be .ing provided with a discharge outlet leading through the end thereof and another disclnirge outlet leading; throiug h the side thereoi", and one oi the objects oi the invention is to provide ll'l'lPl'OVOLl means tor selectively controlling the outlet openings whereby the n'iaterial delivered tliirough the chute may be selectively directed at will through one or the other of the said outlet opening-s, the said C(Jli'tIUlllllg means also operating as a deflector for the n'iaterial.

To the attainment ot these ends and the arr-oniplislnnei'it ot' other new and uselul oh lieclis as will appear, the invention (ZOllSltSllS in the 'lcatures of novelty in substantially the t.()t] %ll1l(f't l()l1 eoinhinatimi and arranogeinent oi the several parts hereil'la'liter more il ully described and clain'iediuul shown in the accompanying drawing illustrating this invention, and in which lii iture l a :lront plan VlOW ol. the scoop ot a snow plow and ii'upeller casino; with the discharge chute there'l or, partly in section and. having an attachment constructed in accordance with the principles of this invention applied thereto.

l igure is a detail top plan View of the outer end of the chute with the attachment applied thereto.

.llelcrring more particularly to the drawing the niuneral it) designates generally the scoop of a snow plow having an opening "l'l. in, the bottom thereof, through which the material is led to an impeller 12, the latter being out any suitable construction and which iinpeller discharges the material. through a discharge chute 13, the latter being plfOv'lClQtl with a discharge outlet opening;- let through the end thereotl and a lateral discharge openinp; 15 through the side lZl'lGT'QOf.

'lhe chute may be oi any desired size and cordiguration, and is preferably provided with guides 16 therein and on opposite sides thereof, and which guides arch in a direction across the chute and form a support for the ends of a plurality of elements 1? which are tleuibly connected together, such as by piroh and which elements are adapted to be projected across the chute to form a deflector :tor deflecting the material through the opening 15.

These elements 1'? may he of any desired construction and are preit' 'aoly connected at their extren'iities with chain like devices 18, which latter are provided with rollers it} adapt-ed to engage and. move upon the guides Hi.

The chute 13 is preterably provided with an opening 20 in the side thereof through which the elements 1.? only be retracted or projected into the chute.

11y suitable means may be provided. for shitting the deflector formed by the elements it", such as toothed or sprocket wheels 21., which latter are connected with a sl'ialt 22 journaled in suitable brackets 22-) in'etterably secured to a support or to the chute iii. A pulley 2st may also be connected with the shalt 22, and this pulley is adapted to be to tatedfrom any suitable source.

ll ith this .lll'lPlfOVtldGOllSljlllChlOll it will he manifestthat by controllingthe adjustment or position ol. the deflector formed by the elements 1'? the direction of travel given to the material from the chute 13 by the inipellor may be controlled. that is, the material may be caused to he delivered. through the outlet l4; or the outlet 15 as desired.

Vl hen it desired to deliver the material through the outlet: 15 the deflector 17 is moved into the position shown in Figure 1. That is it is projected into and across the chute 13, thereby closing the outlet opening ll; to the discharge of material there through,

l i hen the detlcctor 1'? is retracted. it will be withdrawn 'lroni the chute and will and adjacent the outside of the chute 13. l i hei'i in this position the material will be delivered through the outlet 14.

This construction is particularly advantageous in that when occasion may require, the snow or i'naterial being handled by the impeller will be prevented from being delivered on the sidewalk or a. portion of the road where it might be objectionable or in the way, and insi'u-es the delivery of the n1atorial at a position along; the road bed or line ot travel of the machine.

lVhile the preferred iorln ot the invention has been lterein shown and described it is to be understood that Various changes may be made in the details of construction and ill) in the combination and arrangement of the several parts, Within the scope of the claims, Without departing from the spirit of this invention.

What is claimed as new is:

1. In combination, a discharge chute having two outlet openings, one of said openings leading through the end of the chute and the other laterally through the side of the chute, a flexible deflector adapted to be projected across the chute for closing one of the said openings and for directing the material through the other of the openings, and means for causing the deflector to form an arch across the chute intermediate the said opening.

2. In combination, a discharge chute having two outlet openings, one of said open- 1 ings leading through the end of the chute and the other laterally through the side of the'chute, a flexible deflector adapted to be projected across the chute for closing one of the. said openings and for directing the material through the other of the openings, and curved guides for guiding the said doflector in its movements whereby the deflector will be caused to arch across the chute.

3. In combination, a discharge chute, said chute having an outlet leading through the end and an outlet leading through the side thereof, a flexible deflector adapted to be arched across the chute. between the outlet openings. for deflectingthe material through the outletin the side of the chute and for closing the other outlet, and means exterior ofthe. chute for actuating the said deflector at will.

4. combination, a discharge chute, said chute having an outlet leadingthrough the end and an outlet leading through the side thereof, a flexible deflector adapted to be projected across the chute between the oiulct openings for deflecting the material through the outlet in the side oi? the chute and :l'or

closing the other outlet, means exterior of the chute for actuating the said dellccior at will, the said dcl'lcctor clnluuljing a plan rality of elements pivotally connected together, and guides disposed adjacent the ends of the said elements.

5. in combination, a dclivcrv chute having tn'o outlet openings. at 'llcxible delicctor normally disposed outside oi? the chute. and means for projecting the deflector into and across the chute between the said openings to close one of the openings and tl'or directing the material through throthcr of the said openings, the said deflector arching across the chute and embodying a plurality ol? elements swingingl connected together.

(i. In combination, a deliver chute having tno outlet openings, :1 flexible dcilcclor normally disposed outside of the chute. means for projecting the deflector into and across the chute between the said openings to close one of the openings and lor directing the material through the other of the said openings, the said deflector arching across the chute and enibinlying a plurality oit'elements swingingly conncctcd l( 1f(l1ll(l. and guides Within the chute for the ends of the said elements.

In testimony whereof, I have signed. my name to this specification, on this lllh day of May, 1925.
