Abstract

110,387. Gill, H. A., (Angular Drill & Machine Corporation). Oct. 16, 1916. Drilling-machines for producing square holes are arranged for portable electric motor operation. A stand 40, Fig. 2, with a serrated base for engaging the work and with holes 45 for spikes or pins, has a splined connexion with a casing 20 containing a square guide in two interfitting parts adjustable by a right and left hand screw. A groove and set-screw 42 limit the extent of movement under the influence of a spring 28. A yoke 16 for engagement with the electric motorhas set-screws .17 engaging a groove in the casing, a ball bearing 27 being interposed as shown. The stand may be modified as shown in Fig. 8 or as in Fig. 9, while the jaws 48 are adjustable by a right and left hand screw. Lathe and like devices.-A driver 53, shaped as shown in Fig. 3, is secured to the drill shank by a screw 54 hooked by a spring 57, to allow the necessary float.
