Serial No. 637,953.

To (All whom it may concern.

Be, it known that I, LESLIE M. SHERIDAN. a citizen of the United States, residing at Anaconda. in the county of Deerlodge and State of Montana. have invented a new and useful Ore-Sampling Device, of which the following is a specification.

This invention relates to improvements in ore sampling devices. and the primary object of the invention is the provision of an ore sampling means adapted to be disposed between the spout of an elevating apparatus or delivering hopper provided with a receiving hopper having a sampling discharge and an ore discharge, with means interposed therebet-wecn for intermittently permitting the ore to enter the sampling discharge and during other period of time to cause the ore to tlow in the. regular ore discharge into the proper concentrating or amalgamating apparatns,

A further object of the invention is the provision of a novel structure of what is termed ore cutter disposed for sampling ore and operably connected by a peculiar form of cam whereby said cutter is operated to permit the ore to How for the greater length of time to the proper ore discharge and at intermittent periods and for a short period of time to conduct a sample from the main ore flow to the sample discharge. thus producing a cutter of very simple construction and of few wearing parts, and so timing the same as to produce the desired result.

A still further object of this invention is the provision of a novel form of receiving hopper having a sample discharge and what is termed a rejection discharge in combination with an oscillatory ore cutter disposed above the said hopper and operably connect d with a cam device for disposing the same with relation to the discharge spout of an ore hopper so that the ore is permitted to flow at the desired time into the sample dis charge spout or to the rejecting discharge spout.

Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed. it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without dcparting from the spirit of the invention.

in the drawings Figure 1 a side elevation of the complete device, dotted lines illustrating the position of the cutter and cam and permitting the ore to be discharged in the sample spout. Fig. 2 is a top plan view of the invention showing the support ing frame. Fig. 3 is an elevation taken from the upper end of the apparatus, the sampling hopper being shown in cross section with the cutter discharging into the rejection discharge of the apparatus. Fig. 4 is a detailed perspective view of the cutter removed. Fig. 5 is a detailed view showing the rocking arm and roller for engaging the cam to operate the cutter.

Referring to the drawings. the numeral 1 designates the elevator hopper or tunnel or in fact any device which is adapted to receive the ore and convey it for sampling and concentration or amalgamation the same being provided with the discharge spout 2. which empties into and above the receiving hopper 23. This receiving hopper as clearly shown is provided with the central curved partition wall 4 which divides the hopper into the main receptacle 5 and the sample receptacle 6, the main receptacle being provided with the discharge spout 7 while the sample receptacle hopper is provided with the discharge spout 8. the said discharge spouts being disposed. as shown in Fig l at oppositely disposed angles. for conveying the ore in the desired direction and place for concentration and amalgamation or for sampling.

The main framework as clearly shown has disposed therein the transverse shaft 10. and upon its end near the hopper is a sleeve or collar 11. carrying the integral depending lug or connecting arm 12. for the detachable reception of the lug 13 of the cutter or deflecting spout 14. which is provided with the two inwardly inclined triangular shaped walls 15, which cause the cutter to be a chute or spout to normally be held below the lower end of the spout 2 and convey the. greater portion of the ore therethrongh into the receptacle 5 and through the spout T.

Mounted upon and adapted to rock with the shaft 10 at the opposite end from the collar 11 is a crank arm 16. provided with a pin 17. which pivotally connects the said crank arm to the pitman or connecting rod 18, whose other terminal is pivotally mounted upon the pin it) carried in the lower free end of the oscillatory arm or link 20, whose upper end is pivotally connected upon the shaft in the brackets 21 as clearly shown in Figs. 1 and 2. It will thus be seen that the said arm or link 20 when being rocked or reciprocated will impart to the cutter l t a movement to cause the same to assume the position as shown in full and dotted lines in Fig. t. In order to actuate the said link 20 and the rod 19 and consequently the cutter 14 as desired, upon the inner end of the pin 19 is mounted an antifrictional roller 32, which normally moves within the cam groove of the cam 23, the said groove 24 being provided with the small inner concentric portion It and the enlarged outer concentric portion 7), the inner portion of the cam 23, holding the cutter 1-1- in the position as shown in full lines in Fig. 1 but when the said roller 22 is in engagement with the portion of the cam at 1), the said cutter 14 will assume the position as shown in dotted lines in Fig. l and therefore permit the flow of the ore to the spout 8 not deflecting the same into the spout 7. The cam '23 is keyed upon the outer end of the shaft 25, which is mounted in the frame 9 and is operated by the fast and loose pulleys 26 as clearly shown.

From the foregoing description it is evident that the cam may be so constructed to time the operation of the cutter or chute it so that the desired sampling of the ore will be accomplished momentarily and at the desired time the quantity taken for a sample being determined by such timing and not interfering in the least with the discharge of the ore from the elevator hopper or other source. It will also be seen that the hopper is disposed to convey the ore to the spout T and is not employed to convey the ore to the spout 8, the same being mounted above the compartment 6 and when in operable relation with the spout 2 will at all times convey the ore to the compartment or receptacle 5 and the spout 7, and when in the position for sampling will be from below the spout 2 to permit access of the ore to the spent 8 of the compartment or receptacle 6. By this means the wear upon the spout is greatly reduced and even in case where the same needs replacing, it is simply necessary to detach it from the arm 12 and replace it with a new one.

What is claimed is 1. The combination with an ore supply hopper and a sampling hopper divided longitudinally by a partition having a curved upper edge and having two oppositely inclincd spouts, one upon each side of said partition, of a frame, a power shaft journaled therein, a cam rotatable with said shaft, a link pivoted at one end to a fixed pivot and having its free end in engagement with the cam, a rod pivoted to the free end of the link, a rock shaft journaled in said frame. a crank arm carried at one end thereof and operably connected with said rod, a connecting arm carried upon said rock shaft at the opposite end to the crank and depending above one side of the hopper, and a cutter carried by said connecting arm and disposed for oscillation within the hopper above the partition and between the spouts and the supply.

2. The combination with an ore supply hopper and a sampling hopper divided longitudinally by a partition having a curved upper edge and having two oppositely inclined spouts, one upon each side of said partition, of a frame, a power shaft journaled therein, a cam rotatable with said shaft, a link pivoted at one end to a fixed pivot and having its free end in engagement with the cam, a rod pivoted to the free end of the link, a rock shaft journaled in said frame. a crank arm carried at one end thereof and operably connected with said rod, a connecting arm carried upon said rock shaft at the opposite end to the crank and depending above one side of the hopper, and a cut ter connected to the connecting arm, said cutter having an inclined chute and two inwardly inclined walls, the lower edge of the cutter projecting beyond and below the curved upper edge of the partition of the hopper and describing an arc of a circle to conform to the curved upper edge of the partition when reciprocated.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

LESLIE M. SHERIDAN.
