ICE-ELEVATO R.

SPECIFICATION forming part of Letters Patent No. 718,175, dated January 13, 1903.

Application filed April 14, 1899. Serial No. 718,069. (No model.)

T0 @ZZ whom t may concern:

Be it known that I, NEWELL l-I. TRASK, a citizen of the United States of America, residing in Kansas City, in the county of Jackson and State of Missouri, have invented a new and useful Improvement in Ice-Elevators, of which the following is a specification.

My invention relates to improvements in ice-elevating machinery.

The object of my invention is to provide an ice-elevator which is cheap in construction, readily applied to existing ice-chutes, not liable to get out of order, and economicallyand efficiently operated.

My invention provides certain novel and useful features hereinafter fully described and claimed.

In the accompanying drawings, illustrative of my invention, Figure I represents a vertical longitudinal sectional View of an ice-elevater constructed in accordance with the principles of my invention. Fig. AIl represents a transverse vertical sectional view taken on the dotted line ot b of Fig. I. Fig. III represents a top view.

Similar letters of reference indicate similar parts.

A indicates -the ordinary inclined chute,

. through which the ice is forced upwardly.

B indicates the water-section, U-shaped in cross-section, of the chute and hinged in any desirable manner at its inner end to the posts C, to which the lower end of the chute A is secured. The outer end of the water-section B floats upon the water and may be submerged therein to any desirable depth in the manner hereinafter described. On each side of the chute A is a pair of rails D, disposed one above the other, between which run the wheels E of a carrier or truck F, which has secured at its forward end a hoisting-rope G, secured to an eyebolt I'I, with which the carrier is provided. The vertical distance between the rail D is sufficient to permit the swinging of the free end of the water-section without cramping the wheels E of the carrier. An inverted U- shaped device I for engaging the ice is hinged by its horizontal section to the forward end of the carrier F at a point preferably above the eyebolt H. The downwardly-extending arms of the ice-engaging device I are adapted when in the position shown in Fig. I in solid Athe desired depth.

section.

lines to bear upon the forward end of the carrier below the eyebolt H. Vertically adjustable upon the arms of the device I is a transverse horizontal bar J, disposed upon the forward side of the said arms and secured theretoby any suitable means. Such means I have illustrated as comprising two U-bolts K, one embracing each arm and extending through holes provided in the bar J, to which they are secured by nuts L, having screw-thread connection with the U bolts. This barJis adapted to prevent the uptipping ot' thin ice in the chute, which otherwise might pile several layers deep against the arms. The rails D over the water-section B are pivoted to the posts C and are provided at their outer ends with transverse openin gs adapted to receive each a bolt M, adapted to be inserted in an opening, of which there are a series, indicated by Nin each of two upwardly-extending posts S O, rigidly secured to the outer end of the floating section B. Extending across the section B above the upper rails D and preferably supported thereon is a plank P, upon which a weight Q of any size may be placed for submerging the outer end of the section B to By moving the weight Q toward and from the posts C the submersion of the outer end of the oating section maybe adjusted to the degree desired. Any suitable power may be employed to drawthe carrier up the inclined track.

My invention is operated as follows: The various parts having been assembled, as hereinbefore described, sufficient weight Q is placed on the plank P to submerge the outer end of the section B, so that the bottom of the ice cakes (indicated by R) will just clear the bottom of the chute. lf submerged too deeply, the ice will turn over in the floating The outer ends of the track-rails D on the water-section are then vertically adj usted on the posts O to the proper height above thev 'water by inserting the bolts M in suitable openings N in the posts 0. The inner ends of this portion of the track need not be changed, as there is comparatively no vertical movement of the water-section at the inner end. The carrier F is then let down after the ice has been run into the water-section B, and the inverted-U-shaped device I will swing into the position shown in dotted lines in Fig.

I until the carrier has passed into a position in which the arms of the said device will drop behind the last ice cake. Power is then applied to the rope G and the carrier will be drawn upwardly on the track-rails D, and through the intermediacy of the device I the ice will be forced upwardly into the chute A, in which it may be carried to any point desired. 'If the ice is thin, the bar J may be utilized, being secured at the required distance from the bottom of the chute to prevent the rear end of the last cake uptipping. When the ice is quite thick, the bar .I `may be dispensed with. Many modifications may be made in construction without departing from the spirit of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In an ice-elevator, the combination with an inclined chute, having a water-section hinged at one end and floating at the other end, of a track adjacent to the chute and vertically adjustable with reference to the lioating end of the water-section, a carrier mounted upon the said track, and an ice-engaging device carried by the said carrier, substantially as described.

2. In an ice-elevator, the combination with an inclined chute, having a water-section hinged at one end and floating at the other end, of a track adjacent to the chute the lower end of the said track being supported by the floating end of the water-section and verticallyadjustable with reference thereto, a carrier mounted upon said track, and an ice-engaging device carried by the said carrier, substantially as described.

3. In an ice-elevator, the combination with an inclined chute, having a water section hinged at one end and fioating at the other end and provided at its floating end with upwardly-extending posts, of a track located adjacent to the said chute and vertically adjustable at its lower end upon the said posts, a carrier mounted upon the said track, and an ice-engaging device carried by the said carrier, substantially as described.

4t. In an ice-elevator, the Vcombination with an inclined chute, having a water-section hinged at one end and floating at the other end, of means for adjusting the degree of submersion of the floating end of the water-section, a track located adjacent to the chute, and vertically adjustable with reference to the said floating end of the water-section, a carrier mounted upon the said track, and an ice-engaging device carried by the said carrier, substantially as described.

5. In an ice-elevator, the combination with an inclined chute, having a water-section hinged at one end and floating at the other end and provided at the oating end with upwardly-extending posts, of means for adjusting the degree of submersion of the floating end of the water-section, a track located adjacent to the chute and supported at its lower end by and vertically adjustable upon the said posts, a carrier mounted upon the said track, and an ice-engaging device carried by the said carrier, substantially as described.

y6. In an ice-elevator, the combination with an inclined chute, having a Water-section hinged at one end and floating at the other end, of .a track located above the chute and the Water-section, the section of track over the water-section being hinged at the inner end and supported by and vertically adjustable upon the floating end of the water-section at the other end, substantially as described.

7. In an ice-elevator, the combination with a chute, of a track located adjacent to the chute, a carrier mounted on the track, an inverted- U-shaped device hinged to the carrier and adapted to engage the ice when the carrier is moved in one direction, and a bar secured transversely to the arms of said device for preventing uptipping of the ice relative to the said arms, substantially as described.

In testimony whereof I have affixed my signature in presence of two witnesses.

NEWELL H. TRASK.
