IMOTOR-DRIVEN SWING-SAW.
One object of our invention is to provide a simple form of construction which will be readily adapted for the use of an independent electric motor for driving the swing saw. Another object is to provide adjustability in the structure, such as for adjusting the belt to the proper degree of tension and for adapting the same structure to motors of different makes.
In general, the object of our invention is to )roduce a swin saw construction which wil be simple, e cient and adapted to be readily manipulated.
These and other objects of our invention will be understood from the following de'-,
scription and accompanying drawings, in
which Figure 1 is a front elevation of one form of embodiment of our invention; Fig. 2 is a side view thereof; Fig. 3 is a view partially 5 in section showiing the eccentric construction;
Fig.4 is a front elevation of the motor showing adjustment to a different position than in Fig. 1; and Fig. 5 is a face view of the preferred form of washer for the motor.
The main supporting-frame is shown as having a base 1 adapted to be bolted to the.
supporting means and has extending therefrom thearms 2, 2 giving a main frame of U-form. Upon this main frame is formed 5 a seat or bed 3 supporting the electric motor 4 and to which the motor is bolted. The motor pulley 5 drives the belt 6, which in turn engages the ulleys 7 on the shaft of the saw 8. This sha is supported on opposite sides .Of the pulley 7 by the frame 9 having two extensions 10, 11 at the upper end thereof which have a pivotal connection with the arms 2.
It'may be desired to have the axis of the' m motor shaft coincide with the pivotal axis of Specification of Letters Patent. Patented Aug 24, 1909,
Application filed December 7, 1907.
Serial No. 405,523.
the arms 10 and 11, and so avoid any substantial change in the tension of the driving belt 6 for difl'erent positions of the arm In order to provide adjusting means for securing or approaching this condition, we have found it quite advantageous to provide'an eccentric adjustment in the pivotal connection between the arms 2 and 10 and 11. One form of such adjustment in indicated in Fig.
3, in which the connecting pin has a bearing portion 12 in the arm 2 of different diameter and eccentric to the other bearing portion 13 which engages the arm 11. Thus by turning this pin in the arm 2 the pivotal axis. of arm 9 can be raised or lowered conven- 7o iently and the adjustment fixed at any desired position by a bolt 14: which screws through the bearing portion of arm 2 and fixes the connecting pin in any desired position. It will be understood that a similar pivot connection is formed between the arm 10 and itsadjoining arm 2, and may be adjusted in the same manner. This feature of construction is particularly advantageous for adjustment to suit different makes of motors in which the height from the axis of the motor shaft to the plane of the base will vary appreciably. Thus if a motor when placed in position is of such dimensions that the axis does not coincide with the axis of the's s part 12, the eccentric pins may be turned as desired so that the axis of the parts 13 will be in the same horizontal plane as' the axis of the motor, and the motor may then be shifted slightly backward or forward on its seat 3 so that the motor axis will substantially coincide with the axis of parts 13 and bolted in place, the bed plate 3 having openings for receiving the bolts 16, such for example as slots 24 which are common in bed plates.
Also with the. same motor it may sometimes be desired to change the adjustment to suit particular conditions or change of conditions, and in such cases the adjustable eccentric serves to conveniently secure the desired adjustment.
It will be understood that the eccentric means 12, 13 is capable of 'securin the desired adjustment when the disp acement necessary to effect this adjustment is equal to or less than its eccentric radiusl. When the displacement is greater than the eccentric radius, we provide means for adjustlng the motonitself for the purpose of providing additional range of adjustment and for adjusting the tension of the driving belt, which means, in the particular form indicated in Figs. 1 to 5, comprises a plurality of washers 15 of U-form as shown in Fig. 5, through 5 which 'the'- bolts 16 pass, which bolts pass through the base of the motor and secure the motor to the seat or bed 3. In Figs. 1 and 2, thewashers- 15 are all shown on oneside .of the base of the motor and between this base and the heads of the .bolts 16, thereby securing a position of the motor directly upon the seat 3. If it be desired to loosen the belt or secure a different position of the motor, or from any other consideration, the bolt 16 may be loosened and the washers 15 may then be readily removed sidewise and placed around the bolts between the m0- tor base and the seat 3, the number of washers transferred being such as to secure the de- 20 sired adjustment. For example, in Fig. 4, two washers are shown inserted between the motor base and the seat 3-, and thus secure a lower position of the motor as a whole. The bolts 16 may then be tightened to firmly secure the motor in place.
For securing a biased position to the swing saw, we provide a lever 20 pivoted to one of the arms 2 as shown in Fig. 2, and having an adjustable-weight at its outer end. The
i level- 20 carries a roller 22 which engages a plate 23 fixed to the arm 9 and thereby tends to constantly force the arm of the swing saw to a backward position.
A motor starter or speed controlling switch will be conveniently arranged in a position near the operator so that he may readily manipulate the swing saw or controlling switch from the same position. We sometimes support the motor controlling 40 switch independently, but in some cases it 1 said rotary motor to transmit will be desirable to support the controlling switch directly u on the arm 9.
Having thus dgscribed our invention, we declare that what we claim as new and desire to secure by Letters Patent, is,
v 1. In a swing saw, thefcombination of a main frame having extensions, a rotary motor on said .frame located between said extensions, an auxiliary frame ivoted to said extensions and carrying a driven element, means for adjusting the axis of the pivot of said auxiliary frame with reference to said extensions, intermediate means fortransmitting power from said motor to said driven element, and means permitting adjustment of said motor on the frame to determine the position of the axis of the shaft of said motor with reference to the axis of the pivot of said auxiliary frame.
2. In a swing saw, the combination of a main frame having extensions spaced from each other, a rotary motor on said main frame located between saidextensions, an auxiliary frame pivoted to said extensions,
a driven element carried by said auxiliary frame, intermediate means cooperating with ower therefrom to said driven element, an means permittin adjustment of said motor on said main rame to determine the position of the axis of the shaft of said motor with reference to the axis of the pivot of said auxiliary frame.
In testimony whereof we affix our signa tures, in presence of two witnesses.
