Specification of Letters Patent.

Patented June 22, 1909.

Application filed January 25, 1909. Serial No. 474,035.

To all whom it may concern:

Beit known that I, ERNEST P. LORCH, a citizen of'the United States, and a resident of the city of New York, borou h of Brooklyn, in the county of Kings and Estate of New ments in power scoops, and more particularly to certain features of construction whereby the machine is rendered more efl'icient in its operation and whereby the material operated upon is removed from the ground and conveyed to a truck separate from the power scoop.

In the type of machines to which mine relates, a vehicle is provided with a prime mover for propelling said vehicle, and is also provided with a scoop for removing the snow or other material from the ground and deliverlng it to a conveyer. The conveyer is also driven by the prime mover and transports.

the material from the scoop to the upper portion of the machine. The material is then permitted to descend by the action of gravity to a separate truck or wagon adjacent the vehicle.

One object of my invention is to provide certain improvements whereby if the scoop in advancing should meet an obstruction, such asa projecting manhole cover or the like, it may slide backward and in doing so reach a higher level and pass over the ob struction, the scoop being immediately returned to its original position by means of a compressed elastic medium or member.

A further object of my invention is to facilitate the transferring of the material from the scoo to the conveyer,'for accomplishing which 0 ject I provide a baffle wheel which may also serve to break up the material.

A further important feature of my invention residesin the chute whereby the material transfcrred to the conveyer may be deposited in a truck at either side of the vehicle desired, there being two separate side chutes Reference is to be had to the accompanylng drawings, forming a part of this s-pecifica tion, in which similar dharacters'of reference indicate corresponding parts in all the figures, and in which- Figure 1 is a side elevation of a power scoop constructed in accordance with my invention; Fig. 2 is a rear view thereof, a portion of one chute being broken away Fig. 3 is a central vertical section of the front endof the scoop, said section being taken on theline 3-3 of Fig. 4; Fig. 4 is a vertical transverse section through the scoop, said section being taken on the line 4-4 of Fig. 3; Fig. 5 is a sectional detail of a portion of thescoop; Fig. 6 is an end view of an ice-breaker, which may be employed in place of the baflie wheelshown in Figs. 1, 3 and 4; and Fig. 7 is a sideelevation of the ice-breaker shown in Fig. 6.

In the specific construction illustrated in the accompanying drawings, 1 provide a vehicle having a main frame 10, front steering wheels 11, and rear driving wheels 12. The vehicle carries any suitable form of motor 13-, for driving a shaft 14, and this shaft is connected to the rear wheels by a chain 15, and to a countershaft 16 by a chain 17. The conveyer hereinafter referred to is driven from the shaft 16, so that it will be noted that the engine operates not only to drive the vehicle, but also to drive the operating parts of my improved mechanism. The details of construction of the vehicle-driving means and" connections from the motor to the conveyor may be varied at will, as the details illustrated are not considered at all important. At the front of the vehicle and between andin advance of the front wheels 11, I provide a drum 18 over which the belt 19 of the convcyer passes, and at an elevation above the frame of the vehicle and adjacent the rear end, I provide a second drum 20, also having provided, foldable to inoperative position.

and both of them designed to receive the material at their upper ends.

Other special features of construction and important parts of my invention will be set forth hereinafter and particularly pointed I for engaging with the material to prevent it out in the claims.

engagement with and supporting the conveyer belt. The front drum ma be supported by hangers 21, extending own from the frame 10, while the upper and rear drum may be supported by any suitable form of standard 22. The two drums may be held at a definite distance from each other and the hangers 2.1 and the standard 22 may be braced by connecting bars 23. The con veyer belt carries a plurality of rods, plates, or flanges 24, extending transversely thereof from sliding down the belt, the number and size of these being dependent upon the nature ofthe material erated upon.' The detail construction of t e conveyer itself con- 5 stitutes no portion of my'invention.

At the front end of the vehicle and sli htly in advance of the drum 18, is an inc ined plane constituting a scoop and made up of two se arate sections 25 and 26, slidably connecte together. One of these sections 25 is hinged at its rear and upper end, and at its front end it is supported upon small rollers or wheels 27, so that the relative position of the scoop in respect to the ground will not be varied by the passing of a vehicle wheel over an obstruction or into a depression in the ground or avement over which the vehicle travels. e rear hinged end of the section 25 is on substantially the level of the axis of the drum 18, andextending downwardly from the hinged edge'is a curved shield 28, concentric with the drum and serving to a certain extent as a container into which the ,material is deposited from the upper end of thescoop and from which the material is removed by the conveyer. The curved shield ".28 serves as a housing to also protect the lower end .of the conveyer. The front sec-' t'ion 26 has its front ed e adjacent the ground andits rear edge ovefiaps the other section 25. The two sections are slidably connected together and suitable mechanism is provided for normally holding the front sectlon 26 in its forward or advanced position. This mech- 85 anism may include a plurality of cylinders 29 carried by the section 25 upon its under surface, and within these cylinders may be provided istons 30 connected to piston rods 31 exten mg to points adjacent the under surface 4 of the forward section 26. The front ends of the drilston rods are extended u wardly and r gi y secured to the under side of the section 26, and the cylinders in the rear of the pistons may contain any elastic material or medium under compression, for instance, com ressed air. A coil spring may be used 1m p ace of the compressed air, if desired. The front edge of the section 26 travels closely adjacent the ground or pavement, so

as to remove as large a quantity as possible of the snow or other material, but should this front edge strike an obstruction, as, for Instance a manhole cover, or the like,'the section may slide rearwardly over the upper surface of the rear section 25, and, at the same time, these'ction 26 will be lifted upwardly, as the front end of the section 25 is positivel supported by the wheels 27. The rearwar movement of the section 26 compresses the air, spring, or the like, in the cylmder 29, so that as soon as the'front section asses over the obstruction, it is immediately orced forwardly and downwardl again into its normal operatin position. he section 5 26 may be formed 0 a single plate, ifidesired,

the material upwardly along the upper surbelt 39.

or it may be subdivided longitudinally of the machine into a plurality of separate pieces independently connected to the section 25,- so that should one piece strike an obstruction .and be forced rearwardly, the remaining 7a pieces of the section may remain in operative position, as shown particularly in Figs. 4 and 5. The section 26 is subdivided into three separate pieces and the meeting edges of the a jacent pieces are protected and concealed by stri s26? These strips extend longitudinal y of the machine and are carried by one piece of the section and extend over a portion of the adjacent piece.

The two sections 25 and 26 are preferably so held in respect to each other that any other movement than a sliding movement is prevented, but this movement is facilitated as much as possible. For instance, the section 25 may have slots 32 extending longitudinally thereof, and the top section 26 may have depending brackets 33 extending through these slots. .Each bracket may i have a roller 34 disposed within theslot for engagement with the sides thereof, so as to prevent lateral movement of theupper section, and may have oppositely-disposed rollers 35 in engagement the under side of the section 25, to prevent the uppersection from being raised out of engagement with the lower section.

The front edge of the front section 26 is considerably wider than the vehicle, so that the scoop will cover a very wide path, but as the conveyor is narrower than the distance between the vehicle wheels 11, I PTO, vide the rear section 25 with side plates 36 having their front ends adjacent the side edges of the section 26 and having their rear ends converging toward the conveyer'and terminating adjacent the opposite sides thereof. Intermediate the two side plates 36, I provide a rotary member for advancing face of the S000 and depositing it adjacent the lower end-o the conveyer. In the form shown in Figs. 1, 3 and 4, this rotary member is in'the form of a drum 37, having outwardl extending baffles 38, the drum bein rotatable about an axis substantially paralle to the axis of the drum 18.

The baflle wheel is rotated in the reverse direction to the drum-18, that is, its under side travels rearwardly, whereas, the under side ofthe drum 18 travels forwardly. For driving the drum 37 from'the drum 18, I may provide any suitable mechanism, for instance, a crossed Instead of making the baffles 38 continuous throughout the length' of the body, of the rotary member, I ma} divide them into sections and utilize the rotary member as a pick or breaker forsubdividin the materia As shown'in Figs. 6 and 7, provide the drum 37 with a plurality of outwardly-curved and pointed baflles or 130 sub- QM... In.

teeth 38, which serve to break up and subdivide any large pieces of ice orfrozen snow, which might tend-to injure the conveyer were they directly delivered thereto.

The material upon being delivered to the conveyer is moved upwardly along with the latter and is prevented from slipping off the edges of the conveyer by any suitable means as, for instance, side bars 40. At the upper end of the conveyer I provide a receiver 41 into which the materlal is deposited and from which it may be delivered to a wagon or truck at the side of the vehicle. The under side or floor of the receiver is formed of two sections 42, 42, inclined in opposite directions and adjacent the lower and outer edges of these floor sections are pivotally connected two chutes 43, 43. Each chute extends outwardly at an angle to the reoeiver and terminates at a distance from the side of the vehicle and at such an elevation that a truck or cart 44 may be drawn along at the side of the vehicle and beneath the end of the chute toreceive the material delivered therethrough. Each chute is preferably hin ed at its upper end and is supported at its ower end by a movable brace or bracket 45, so that the chute may be held outwardly in its operative position or may be swung downwardly into engagement with the side of the vehicle, as indicated in dotted lines at the left-hand side of Fig. 2. Each chute at its outer end is provided with a damper, valve or controller for preventing the material from passin 'therethrough, said damper valve or contro ler being preferably in the form of a curved plate 46, movable transversely of the chute throu h a slot in the by arms 47 pivoted to the sides of the chute.

Within the receiver 41 and pivoted at the intersection of the two inclined bottom sections 42, is a partition 48, subdividing the receiver into two separate compartments.

\This partition may extend upwardly, as indicated in Fig. 2, so that the material will'be deposited in the receiver in approximately equal quantities upon opposite sides and be delivered to both of the chutes, or the partition may be swung in either direction until its upper edge comes adjacent the sidewall of the receiver and the partition lies substantially in alinement with the opposite floor section 42. With the partition in one of its limiting positions, all of the material delivered. to the receiver will go to one of the chutes, while with the partition in the opposite limiting position, all of the material {will be conductedto the opposite chute.

For controlling the position of the artition, the latter is preferably provided wit a downwardly-extending arm 49, intermediatethe two floor sections 42, and a cord 50-is connected to the lower end of this arm and extends over'two pulleys '51. By pulling down one end of the cord, the partition maybe swung toward the opposite side pf the receiver.
