To all whom it may concern:

lie it known that l, Anniziri' N. lhiniienLe-i' of Newton, in the county of lilidtllesex nii Stute o4l Massachusetts, hiive invented certiiin new niid useful lm irovcmcnts in Icellarvcstcrn, of which the ollowing is u speci ficiition.

This invention relates to power mechanism for cutting piirnllel grooves in fields of ice preperntory to converting the icojnto blocks, it ing the practice to cut. interseetin grooves in the upper sui'fiico of the ioe tiel( about. two-thirds of the tliiekiieiis of the, ice, and then complete the detachment of the cakes of ice by splitting the ice in continuotion of said grooves.

My invention is embodied in ii vehicle adapted to run upon an ice field, und provided vvitli n motor. traction wheels ili'iveii thereby for iiiipelliug the vehicle, n troni-verse saw ahaft movable vertically relatively to the home of the vehicle, niul provided with a plurality of saws adapted to cnt groovce of an desired depth in t ic ice, and connections wacn the motor, the i-iiiw shaft nud the drivin wheels, said connections being ldapt to rotate the anw shaft in any position or at any height to which it. nuiy he ndjuat'cd, and to iliipel the driving wheels nt n speed proportiometc to the depth of the eut of the nwo, no tlmt the innchino muy be driven at its minimum speed when the saws are at their maximum depth, und at n maximum s when the siiwa are nt their minimum epth.

The invention consists in the several improvements which I will now proceed to dcacribo and claim.

Ofthe accoinpiin ing drawings, forming a part of thin speci nom-Figure l re reacnta a longitudinal vertical section o an ico-harvesting machine embodying my invention, the said section being on the plane l of line C D of Fig. 2. FiF. 2 re recente a ane horilontal notion on the p o line A B of Fim, and a plan view of the parte below aald Fig. represents a front end elevaticn of the machine. Fig 4 iepreeeiits a rear end elevation. representa in aaparate views, certain etaile ofthe saw shaft and laws. Figa. 0' and 7 l.r'preeent eectional details hereinafter refer to.

The lame numerals of reference indicate the camo parte in all the tlgu ras. The frainc' of the machina, which muy be of any euitebleform, liii supported by traction wheels 3 allixed to a driving axle 4, and runners 5 which are located at opposite sides of the frame.

o represents n horizontal anw carrying shaft, which entendu through the space ba tween the runners 5 und across said runnen, und is provided with u aerien of circular lawa 7. The saw shaft tl is journaled in bearings 8 8 having chunks or arms il, which are pivoted nt 10 to the end portions of a verticallyn'ioviible ca rrier l2, Said carrier being movable in iiides 13 affixed to the siipportin freine.. eens are provided for raisin and lowering the carrier l2 to corres riiise and lower the saw shaft an and thus cause the latter to enter the ice to n only nny desired depth, the said means comprising a. lever 14 pivoted at 15 to a han r 16 mid lever hiivin a movable do 17 at aptod to engage n note ed segment 1 to lock the lever, and hold the carrier l2 and the new! nt. any desired height.

lll represents a gasolene or other suitable motor, anp rted y the frame, the ahaft of the motor' ing shown at 20, and provided with n ily wheel 2l. The motor aliaft 20 formo one member of a rcctional shaft which imparts i'otiiry motion from the motor to thc min' shaft (l. said sectional shaft. including n section or member 22 having a bevel ar 23 nieshin with a bevel gear 24 allix to the saw aft, and an intermediate section or member 25 which is connected with the member 20 vby a clutch 26, and with the member 22 by n universel joint 27, eee Figa.

l and (l. en the members of the clutch 2t) aie engaged with each other, the sectional uhiift im arts motion from the motor to the new elia t, the universal joint 27 permitting the saw alinftto rige and fall aa'indicated by dotted linea in Fig. 1. made for driving the aaw aliaft at any height to .which it may be adjusted and for ci'iiinin each aaw to cut a groove oi any de aired vcpth in the icc. The clutch 26 cnablca the saw ahaft. to be disconnected from tbc motor when it i'a dcaired to impel the inacliine over the icc''witliout driving the nawa.

Connections are. provided between the motor shaft 20 and tli'cdriviiig axle 4, said colinections including nge aperd gear! 22 or other suitable means drivin the axle 4 and traction' wbaala at dieran speeds, ao that the speed of themacliine may be pro- Provision il tbiia y llt t "a" e d engeging ii iiitalil renten.
