If at any time a teacher or other public school employee who is willing to continue, is not re-employed or is discharged before the time when he or she would, under the provisions of this act, be entitled to a pension, then such teacher or other public school employee shall be paid back at once the money, without interest, he or she may have contributed under this act. Should a teacher or other public school employee duly accredited in a city of the first class, accept service in the public schools of another city of the first class, operating under this law, a sum equivalent to all payments, without interest, made by such teacher or other public school employee into the retirement fund shall be transferred to the retirement fund of the city in which such service is accepted. Any teacher or other public school employee who shall retire voluntarily from the service shall receive a refund of one-half of the money, without interest, he or she shall have contributed under this act.

And should any teacher or other public school employee die before receiving any of the benefits or pensions by this act provided, the board of education shall pay to such teacher’s or other public school employee’s heirs or estate the entire sum, without interest, which such teacher or other public school employee shall have paid into such pension fund; and further, if such teacher or other public school employee is retired as an annuitant at the time of his or her death, then if such an annuitant shall have died before he or she has received one year’s annuity, the heirs or estate of such annuitant shall receive an amount from said fund equal to the difference between the amount such deceased teacher or other public school employee has received and the amount he or she would have received under this act had he or she lived for one year after retirement under this act.
