Knight's American mechanical dictionary : a description of tools, instruments, machines, processes and engineering, history of inventions, general technological vocabulary ; and digest of mechanical appliances in science and the arts . tlie edge. These operations are usually doneby separate machines, and with great rapidity. Heel-plate. The plate on the butt-end of a gun-stoek. Heel-polish-ing Ma-chine. {SJiociimking.)One tor smoothing tlie surface of a heel after it issliaped and trinuned. There are several modes. 1. In the El-Fig 2488. lis and Glidden machine, trim-ming and bur-nishing devices,actuated by alever, movearound thesurface ofthe heel,guided by aplate having theform of the fin-ished heel. 2. The bootis jacked and isrevolvedagainst a ro-tating burnish-er, as in 3. The boot isclamped to thesliding frame, and the polisher reciprocated over the surface of theheel by an eccentiie, whose rod is connected to theoscillating arm. (Fig. 2488.) 4. The boot is jacked, the arm b (Fig. 2489) reach-ing down the boot-leg and holding tlie heel to itsseat. The heel is held up to the polisher, and theedge of the heel against the polisher-flange, whichprevents the outer lift from spreading away at its Fig. Heel-seat Cutter. (Shuonakiiuj.) One eni-ployi^l to cut out the concavity in the heel to fitupon the convexity caused by the tilling jiicco ofthe shank. The invention combines with a re-ciprocating gouge-like shank means for relativeadjustment lietween the knife and heel-holder,adapting the same machine to cut heel-seats to titupon dilterent shanks. Heel-shave. {Shocmaking.) A Iiand-tool likea sjjokc-shacc, to shape the heel after the lifts ofapproximate shape have been fastened together. The attaching screws of the curved blade pass Fig. 2490.
