Definitions

  • This invention relates to the connection of typewriters, particularly of the portable type, to a base board.
  • the invention is also applicable to calculating and like machines. For the purpose of transporting such machinesand for protecting them from dust, it
  • the base board is provided with pins or projections over which are pressed rubber or other resilient sockets or feet on thc machine which are formed with corresponding holes and which A are also capable of lateral movement on the machine frame. Ifthe base board works, the only result is thatthe pins adjust themselves in the rubber feet, whilst differences in the distance between the pins and the distance between the fastenings holding the rubber feet to the machine frame are taken up by lateral'movement of the feet.
  • Figs. 1 and 2 are sectional views showing two constructions.
  • Fig. 3 is a perspective view of the machine frame.
  • Fig. 4 is a sectional view of one of the feet.
  • the machine frame 1 is provided with holes 2 into which rubber feet 3 are so forced that a groove 4 in the foot 3 receives two or more of the edge walls of the hole 2 in frame 1.
  • the sizes of the holes 2 and the outer diameter of the rubber feet 3 may be such that the feet can be pressedinto place.
  • the groove 4 is of such depth that it allows the rubber foot a small amount of horizontal sliding movement or play in the hole in the machine frame, as .shown in Figs. 1 and 2.
  • Holes 5 in the rubber feet 3 are pushed over pins 6 on the base board 7.
  • the distances between the pins and elasticity of the feet must be such, that the feet are held firmly by their contractile energy and against any tendency to spread under pressure and elongate the holes while being capable of being readily removed from the pins by hand.
  • the pins 6 may be fastened to the base board in any convenient manner. As illustrated they are screwed into the base board feet 8 by screw-threaded studs.
  • the pins may also have an upper enlargement as in Fig. 2 which fits. tightly through the hole in the rubber foot whilst the shank of the pin is smaller'than the hole in the rubber foot. In such case, greater play is pos- 'sible-in every direction without casual disconnection of the foot from the pin.
  • pins might be fitted to the machine frame and the rubber feet to the base board.
  • the pins or projections may be round, flat or any other desired shape.
  • Means for connecting the frame of a typewriting, calculating or like machine to a baseboard comprising, in combination with a machine frame, and a-baseboard, a set of fastening members consisting of pins on one of said parts and eoactingsupporting members consisting of keeper sockets of resilient material on the other of said parts, each socket having a pin receiving opening of smaller diameter than a portion of the pin for an elastic interlock between the socket and pin, whereby the pins and sockets are held connected by contractile action of the sockets and are adapted to be released under a predetermined disengaging force.
  • the combination with a machine frame, and a baseboard, of fastening projections on one of said parts, and resilient sockets on the other of said parts for engagement with the projections to detachably couple the parts and form cushioning supports for the machine frame, said sockets having an elastic gripping engagement with the proj ections but being otherwise free for slidable engagement with and disengagement from said projections under a predetermined separating force, the said elastic gripping engagement between the projections and sockets being suflicient to maintain a connection between them and to prevent the baseboard from dropping ofi when the machine and the baseboard are jointly lifted from the desk, table or like support.
