' DELIVERY APPARATUS.

Application filed April 13, 1927. Serial No. 188,530.

This invention relates to new and useful improvements in delivery apparatuses The principal object of the invention is to provide a delivery apparatus whereby-articles such asblocks of ice or any other article, which, when supported on tracks,

have a tendency to hang or adhere thereto,

7 may be dislodged and caused to travel downward along saidltracks even thoughthe latter are not disposed at a steep inclination.

Another object of the invention isto provide certain improvements in connection with the delivery apparatus set forth in 'my co-pending application, Serial No. 152,849 which has since matured 1,647,530, issued Nov. 11, 1927 a g F A particular objectof the invention is to provide means operated by the, delivery mechanismforagitating the ice or articles on the tracks prior todelivery to the chute. J

Aconstruction designedfto'carry out the invention will be hereinafter described, to

gether with other features of the invention.-

The invention will be more readily understood from a reading. offthe following specificationand by referenceto the aceompany-' on the line 22 of Fig. 1, I

Fig. 3 is a view similar to Fig. 1 showing the delivery and agitating' 'means in operative positions,

:Fig. 4 is a plan n Fig. 3,

. Fig. 5 is a side View showingiin ean portion of the displacement rail inf tsnormal. position in full lines and in ts operative positionin'dotted lines, 3

Fig, 6 is a plan view of the same, Fig. 7. is a cross-sectional view taken on the line '77 of Fig'. 6, and Fig. 8 is a detai of the lever connection. In the drawings the numeral hers 11 are supported. Thesc tracks are spaced apart and are. preferably made of T-raiia which are inverted so as to form singis -i runners. The track disposed at a Fig. 2 isa transverse sectional view. taken nates in a handle 33.

sufiicient incline to cause blocks of, ice to slide down the same. The lower ends of the members 11 are fastened to the bottom of an inclined chute 12 by means of hangers 3 13. The chute is disposed at a much greater pitch than the track and is fastened on a pair of supporting members-14 of .suitable construction. The chute has side walls 12 and is provided at its lower end'with a housing 15 having'a frame 16, whereby, it is secured in the wall 17 of thestructure in which the apparatus is mounted. The track.

members 11 have their'lower ends terminatspaced below the surface of the bottom of stop or abutment.

Blocks of ice, A, B and C, or other objects, 7

when placed on the track members 11 will slide down the same, the lower front edge of theblock A engagingv the stopf18, as is shown in Fig. 1. -Theblockswi1 l be held in i this position until the block A is dislodged- It will be seen that by elevating thefront .end of the block A and moving it forwardly,

it will be deposited in the chute113 and will thus slide down the same and be delivered.

On the members 12 I mount bearing boxes 19 in which a transverse rock shaft journaled. On the shaft-Ifasten a pair of split collars 21, each having a pair of ears 22. "Between'eachj pair of ears, a dog 23 is pivoted on a pin24, as is shown in detall in Fig. 2. Each dog is tapered to a point and has atripping weight 25 at its opposite end. The weightacts as a counter-balance, but the dog 23 has sufli- Y cient weight outwardly beyond the pivot 24 v I "to normally hold the weight up against view of the parts shown i the collar 21, as is shown in fulllines in 'Figs. 1 and 3. The bottom of the chute 13 has slots 26 extending downwardly from the edge 18 located over the dogs so that I I 29 is provided with a shoulderedaxle 30 7 1O designates" a standard on which a pair of track inemcarrying a roller 31 enga edinfthe slot 28.

' if allowedz-to stand {any length-ftin-1e,-may

tend to adhere to the rails. "The tongues of the T-shaped rails have a tendency to embed in the, under. sides of. the blocks. '[Fhisfcoul'd 1 be overcome \to a great extentl'byigiving'athe track a greater pitch or inelination,but this would involve lifting the bloeks-ef 'iee a greater height to load thern onto the rear of the track and would also create a greater .pressure against the block A, which lrnust .be'glifted 0nto'the1cl1ute'12.

In order to agitateor impel the blocks of'ice" I mount a riserbar or rail 85'between" TlllS rail 35 1s also pre'ferably T- 'shapedi andis inverted to form t a single runner. The riser rail rests at its forward their forward ends'fastened to the sides 12 of the chute. t
