REAR-LOADING SCOOP.

Specification of Letters Patent.

Patented Oct. 18, 1921.

Application filed February 12, 1920. Serial No. 358,076.

T 0 all whom it may concern:

Be it known that HARRY MoKnAN CON- NER, deceased, late a citizen of the United States, and a resident of Scranton, Penn, had prior to his death invented certain new and useful Improvements in Rear-Loading Scoops, of which the following is a specification.

The invention relates to scoops designed for mining operations and which are automatically in operation both-in loading and unloading.

The invention provides a character specified which will prevent the rear closing member from digging into the bottom of the gallery, chamber or passage and which will insure a positive closing ofv the rear gate when the pull rope or cable is drawn upon to move the scoop with its load from-the receiving point to-the point of discharge.

The invention consists in the peculiar formation of therear gatein two members, the manner of mounting and the relative dis-' position of said members, the unique structure of the body with its sides extended to prevent the lower closing member of the gate from digging into the bottom of the gallery, chamber or like opening, and the general structure and arrangement all as more fully set forth hereinafter and pointed out in the subjoined claims and illustrated in the accompanying drawings, in which Figure 1 is a top plan view of the self loading and dumping scoop embodying the invention.

Fig. 2 is a rear end view thereof, Fig. 3 is a front end view of the scoop, Fig. 4 is a central longitudinal section of the scoop showingthe parts on alarger scale,

the full lines showing the relation of the end gates when-closed, and the dotted lines the position of said-parts when open,

Fig. 5 is a detail perspective view of an end portion of the lower rear closing member of the gate.

Fig. 6 is a detail view of an end portion of the lower rear closing member, a portion of. the side of the body and the connecting means between such parts,

Fig. 7 is a detail perspective view of a connecting element of the upper rear closing member,

Fig. 8 is a sectional detail of the connectscoop of the ing means between the upper rear closing member, the body and the operating means.

Corresponding and like parts are referred to in the following description and indicated in the several views of the drawings by like reference characters.

The body of the scoop comprises opposite sides 1, a bottom 2 and front and rear gates. In the preferable form,the body of the scoop is oblong and rectangular. The bottom 2 is formed along its longitudinal edges with upstanding fianges 3 which extend along the lower edges of the sides 1 and are riveted or otherwise secured thereto. The sides 1 are formed at their lower rear corners with ex tensions 4 which are designed to prevent the penetrating edge of the lower closing member of the rear gate from digging intothe bottom of the gallery, chamber, passage or like opening from which the material is to be removed. The lower rear edges of the eXtensions 1 are made'running to constitute runners whereby the scoop may upon its rear movement ride obstructing places. The front gate 5 consists of a plate which is pivotally mounted so as to swing upwardly into open position as indicated by the dotted lines in Fig. 4:. Upper bars 6- and lower bars '7 are secured to the upper and lower portions of the. gate 5 and project rearwardly and are pivoted at their rear ends to the sides of the body as indicated at 8. A lifting element 9 is attached centrally to the upper portion of the ate 5 and providesmeans for swinging said gate into open position when the scoop reaches the unloading point in its forward delivery. The element 9 may be manipulated by hand or operated automatically as preferred.

The rear gate comprises an upper member 10 and a lower member 11 each of said members consisting of a plate. The upper closing member 10 is curved between its upper and lower edges whereas the lower closing member 11 is flat. Both members 10 and 11 are of a length to eXtend' between the sides 1 and the lower member 11 is relatively narrow to prevent its offering a great resistance to the closing movement when extended into the material to be loaded. The rear gate is set forwardly from the rear edges of the sides 1 o that when closed, the members 10 and 11 occupy a position between the sides 1 as indicated most clearly V a socket member 18 similar in Fig. 4. The upper member 10 is pivotally mounted about in line with its upper edge so that'it swingsupwardly and rearwardly when opening as indicated by the dotted line in Fig. 4. The lower closing member 11 is pivotally mounted about in line with its lower edge so that its upper edge swings rearwardly and downwardly when opening. A socket member 12 is secured to each end of the member 11 and is formed with an ear 13. A pin 14 projecting inwardly from the lower rear corner of each of the sides 1 enters the co-acting socket member 12 thereby forming the pivot connection between the member 11 and the sides of the body. If desired anti-friction rollers 15 are disposed between the pins 14: and walls of the socket members so as to facilitate the opening and closing movements of the member 11. A link 16 connects the car 13 of each socket member 12 with a link 17 of, a sectional operating bar. Longitudinal movement of the operating bar effects an opening and closing of the rear gate. The upper closing member 10 is provided with to the socket member 12. A pin 19 projects inwardly from the upper rear corner of each of the sides 1 and enters the cooperating socket 18 thereb pivotally connecting themember 10 to he sides 1. Links 20 connect the socket members 18 with the links 17. When the rear gate is closed the members 10 and 11 assume the position substantially as hown by the full lines in Fig. 4. en the rear gate is open the members 10 and 11 assume the position indicated by the dotted lines in Fig. 4. r The upper edge of the mem ber 11 is beveled so as to readily penetrate the material to be loaded into the scoop. When the rear gate is in open position, the penetrating edge of the member 11 is within the outline of the rear extensions 4, hence is prevented from digging into the bottom of the gallery, chamber or other openin in which the mining operations are carrie on. The lower portion of the closing member 11 overlaps the rear portion of the bottom 2 and is supported thereby. The member 11 is beveled at its upper edge upon the rear side so that the beveled edge occupies the lowest position when the rear gate is open.

This enables uch beveled edge to ride over obstructions.

A sectional operating member is provided at each side of the scoop and is disposed adjacent the inner face of the side 1 and com prises elements 17, 21, 22, 23 and 24. The elements 21 and 24 are pivotally connected to opposite ends of the links 17. Suitable guides 25 secured to the inner face of the sides 1 give properdirection to the operating members and the elements 21 are slidably mounted therein. The end elements 23 and 24: operate through cut away portions of the end gates. A front spreader bar 26 is connected at its ends by links 27 with the forward ends of'the sectional operating members. The-pull rope or cable 28 is connected to opposite ends of the spreader bar 26 in any manner. A spreader bar 29 is connected at its ends with the rear ends of the side operating members and a rope or cable 30 isconnected to the ends thereof.

The pull rope or cable 28 and tail rope or project and are adapted to engage catches 33 at the rear edges of the sides 1. At a suitable point in the rear delivery of the scoop the locking bar 31 is tripped, either by hand or otherwise thereby releasing the engagement so that its members may swing into open 7 lines inFig. 1. This is arranged to take place when the scoop is within a short distance of the load. 'A continued rearward movement of the scoop causes the loose material to pass into the scoop and over the rear member 11. After the scoop has moved rearwardly a distance to receive the required load, a forward pull upon the rope or cable 28 effects a closing of the rear gate by swinging the members 10 and 11 into the position shown by full lines in Fig.4. 'When the scoop reaches a point in its forward movement at which the load is to be discharged the element 9 is drawnupon upwardly thereby swinging the front gate into open position. At this time the scoop tilts and as a result the load automatically discharges therefrom. Any suitable means' may be provided for moving the scoop in opposite directions to receive the load and to 2. A rear end loading scoop having lower rear extensions, a rear gate pivotally'mounted between the sides of the scoop and adapted when in open position'to line within the said rear extensions, and about in line with the lower edges thereof to prevent the digposition as indicated by dotted 7 orm guards,

ging of the closing member into the bottom of the mine openlng during the rearward movement of the scoop.

3. In a rear end loading scoop, a body having lower rear extensions, a rear gate comprising upper and lower closing mem bers disposed forwardly of the rear edges of the sides of the bod the lower closing memher being relative y narrow and adapted when in open position to lie between the said rear extensions and prevented from digging into the bottom of the mine opening thereby.

4. In a rear end loading scoop, a rear gate comprising upper and lower closing members pivotally mounted and means for operating the closing members in unison with each other.

5. In a rear end loading scoop, a rear gate comprising upper and lower closing members, the upper member being pivotally mounted at its upper edge to swing upwardly and rearwardly at its lower edge, the lower member being pivoted at its lower edge to swing rearwardly and downwardly at its upper edge, the lower member being relatively narrow so as to close against the load with a minimum resistance and the upper member being rearwardly curved between its upper and lower edges, and means for operating the closing members in unison with each other.

In testimony whereof I afiix my signature.
